Loyale 2.7 Turbo

Yes, the New -to me- Mazda Booster is workin' Awesome! As I told in previous posts, I've switched cars with my Wife, 'till I got this brakes' issues sorted, Now seems like is time get back onto my beloved Subaru "BumbleBeast" and give back the "KiaStein" to her. Thank you, Josh! _________________________________________________________ I always take Photos and Measurements to go along the explanations, because I Hope that the info I Share, might be Helpful for other people; this "KiaStein" thread seems to be very Huge, because I've all the information regarding to said Kia, on this thread only; While in the case of my Subaru "BumbleBeast", I Wrote Individual Writeups for each different problem & Solution / adaptation \ Improvement that I've done to it; each writeup has been published at the USRM, and all the links to them can be found on the "BumbleBeast" Thread, which is an Index; whose link is at my Signature. Also, at my "BumbleBeast" thread, you'll find a list of links to useful Downloadable Files related to Different Subarus. _________________________________________________________ Back on the KiaStein topic, I'm very Glad to inform that the Brake Pedal is Working Really Awesome, like Never ever Before. Kind Regards.

Now I only need to Change the Rear Drums Brakes, with Rear Disc Brakes. That will improve braking performance by: ► Avoiding the Rear Wheels from Locking easily: that will add Safety. The Rear Drums are Oval, which somehow is "Normal" after 160K Miles / 15 Years of use in an Automatic Car. ► A greater Chamber for brake fluid on the Rear Calipers, will compensate the increased bore Master Cylinder. ► Also, as a Bonus: I'll Get Rid from the Monthly adjustments to the rear shoes, due to the Useless Self adjusters on the Rear Drum Brakes. Kind Regards.

I already Tested the Vehicle's Braking Behaviour on Different Speeds at different tipes of grounds, and I found this, so far: The Brake Pedal is Tall, but is Very Soft and Responsive, plus it has much more sensibility, like a Brand New Car, rolling out from the Dealer; it only needs 25% of the Brake Pedal Travel to stop the Car on average usage, while it needed 75% of Travel on identical usage & circumstances, before I changed these parts. I was Able to Lock all the Four Wheels going at 60 MPH's using 50% less Leg Effort!!! ... and the Brake Pedal still has more travel available, just in case... with the old parts, the pedal would needed to be floored for the same purpose.

The Protege's Booster + Sportage's Master Cylinder installed on the Kia Sephia: This is the Clearance, between the Booster and the Relay & Fusible Box: Now I have Much More Reasons to call this car, the "KiaStein"

After the Install was Finished, I Tested the Vehicle, immediately I noticed an increased sensibility on the Brake Pedal, which still was Tall, but Really much Softer than it was with the Kia's Single Diaphragm Booster. In fact, the Brake Pedal now feels a little taller and Softer than the Average Car on same Size / Segment.

I am Really Glad that I got Rid from the Old worn Master Cylinder and the Damaged Brake Booster from the Kia Sephia, which are pictured here:

Despite that the Outlet pipe on the Boosters, for the Vacuum Hose, are placed a little bit Differently; I managed to plug the same Hose that already was on the Kia, onto this Mazda Brake Booster, and the route for said hose changed a little bit: Now it touches the IAC Valve which was noisy, and now somehow it became much Quieter! The install was extremely easy: Just removed the Old Kia Booster and installed the New -to me- Mazda Booster on its place; I has nothing to change nor adapt, it was a pretty straight install. Despite that the Mazda Booster has a Thicker Body, since its overall diameter is smaller than the Kia Booster, there was enough Room for it plus the Master Cylinder; it fits Perfectly!!!

These are the Differences Between the Kia Sephia Brake Booster I Removed (on the Left) And the Mazda 323 / Protege Brake Booster I installed (on the Right):

I searched on internet for the car on which this Brake Booster came from... ...and it came on an Automatic models of the Mazda 323 / Protege from the 1990's decade. But also it might came in another Mazda models as well... I investigated further online, and I found that the Automatic Mazda 323 / Protege which features this Dual Diaphragm Brake Booster, has the Following Part Numbers: ► BC1G-43-800A ► BG3K-43-800A The ABS model of the Kia Sephia / Spectra with Dual Diaphragm Booster, has a pretty similar part number: ► K2A3-43-800 _______________________________________________________ -----Equivalent / Cross Reference parts numbers for Said Mazda Booster, according to info found online, are: Wagner / Cardone = 53-2528 Bendix = R 2517997 -----Equivalent / Cross Reference parts numbers for the Kia Booster, according to info found online, are: Single Diaphragm Booster: Wagner / Cardone = 53-2049 Double Diaphragm Booster: Wagner / Cardone = 53-8323 ________________________________________________________ DISCLAIMER: I have Not measured nor Tested any other Brake Booster than the JKC 852-04927, so I can not guarantee that the other numbers here written, are exactly the same or equivalent as that one, nor guarantee that they'll fit and work properly; since all this information on part numbers and cross references, were found online at different web sites. I only measured and tested the JKC 852-04927 Brake Booster, but I'm not telling you to do this parts swap; I'm only telling my story; so use all the information I post, at your Own Risk.

Finally, I Found it!!! After taken all the Measurements with my Vernier Scale, and triple check them, I found a Double Diaphragm Booster that only had written in white paint marker letters: "99 Mazda" which has the Perfect Measurements. It says "Bendix License" and has stamped the part number: 852-04927 and the Brand is JKC, which is a Japanese subsidiary of BOSCH. ► It has identical measurements to the Sephia's one on the Rear / Base that has the screws to mount it to the Car / Brake Pedal, also with same long and size screws. Despite that the total lenght of the pin that goes to the pedal was one centimeter shorter, it has adjustment and enough thread left to be adjusted to the proper lenght. ► Also it has identical measurements to the Sephia's one on the front that has the screws to mount the Master Cylinder, also with same long and size screws. The opening also has the same Measurements (inner & Outer) to fit the Sportage's Master Cylinder I Used, which seals perfectly. (so it would work with the Sephia's master cylinder too). I took it Home, it didn't has rust but some paint was fading and was pretty dirty on the outside; so after some cleansing, I decided to spray some Rustoleum Painting, Except the area around the Openings, which were covered with Maskin' tape, to avoid the paint from going inside and damaging the Rubber Diaphragms with its solvents. This is the Brake Booster I Purchased: Note: My Camera's lens creates a weird effect on the Photos that are taken very close, because the mounting screws looks like they were awry to the sides, but they're perfectly straight to the front.

So, searching among different Brake Boosters on their "Brakes" areas at different "Yónkers", I did not found any Kia Sportage / Hyundai Tucson Brake Booster with the proper style I was searching for, only the other style; also there was not a single ABS Spectra Brake Booster available. But, since many Kia Products are based upon Mazda Products; I started to search among Mazda Brake Boosters; after all, the Kia Sephia is based on the Mazda 323 / Protege. So, the Brake Booster I was searching, must have the Proper Measurements to receive with perfect fit, the 1" Master Cylinder I Used: Also it should have the Same Measurements and design, to be installed onto the Brake Pedal as the original one, without any dangerous adaptation: And I Discovered that the Mazda Miata, MX-6, Millennia, certain 626, etc... uses the Same Style Brake Boosters + Master Cylinders than the ones on the Sephia: With elongated push rod that comes out from the Master Cylinder.

The Local Junk Yards, called here "Yónkers" are not like the PaP (Pull a Part) or other styles in USA, because in my Li'l country, they remove the useful parts from the cars, and write on them with water paint markers, the Name / Model \ Year of the car where the part was taken from. The rest of the Car, is sent to the Recycler. So, our "Yónkers" ends being some sort of poor men's department stores, which are organized like this: Overview: Doors / Tailgates: Tail Lights / Grilles: Engines: And much more different Areas, which have only Seats, Bumpers, ECU's, Transmissions, Stereos, Brakes, Glasses, Steering parts, Suspension Parts, etc...

► Then, I went to one of the Local Kia Dealer's parts stores and asked to the salesman to let me see the Sportage's Brake Booster that goes with the Sportage's Master Cylinder I installed, and he showed it to me... but they wanted a Crazy Amount of Money for it... around five times more than the Master Cylinder costed to me; also I asked for the ABS Spectra's (Dual Diaphragm) Booster, but that wasn't available; so I left the Place without buying anything... ► After that, I Went to many, many Aftermarket parts' stores... Sportages came with two different Master Cylinder / Booster designs, one is identical to the Sephia, which has an elongated push rod that comes out from the master cylinder to the Booster; and that mere design, which is the one that I was searching for, is very hard to Find; salesmen at those aftermarket stores, showed to me the other design, which is the traditional where the Master Cylinder only has a hole to receive the Booster's pin. ► Finally, I went to many Junk Yards, which are called here "Yónkers" searchin' for that Sportage's or ABS Spectra's Brake Booster...

PROBLEM: SOLVED!!! And in an Awesome way, let me tell you the long story, short: First I removed the Brake Booster from the "KiaStein" and using my Vernier Scale, I measured how much free space the engine bay has, to accomodate a Bigger / Beefier Brake Booster; in order to see if I could install without problems, the Sportage's Dual Diaphragm Booster that should go with the Sportage's 1" bore Master Cylinder I installed onto the "KiaStein". I found this measurements on the Booster's back:

Yes, of Course!

A Li'l off-topic, but very kindly let me tell you that I Really Like your "Senior" Pictures, This one... ...Somehow is the Better example of the Pride you feel from Driving a Car that you Personally have "Built" Kind Regards.

That is a good idea; but in the case of the "KiaStein", the RPM's are normal, it keeps idling stable at ~ 900 RPM's, a little high because the sedan is Automatic. However, now I Know what went wrong: The Booster Gave up! Today's late afternoon, I was driving back to home from my office, doing ~ 25 MPH behind a huge truck, approaching to a semaphore (Traffic Light) and suddenly, the Brake Pedal was stiff as a Wall... I had to push it extremely Hard to make the car to Stop, and almost hit the Truck, but nothing dramatical, due to the slow speeds and safe distance from it. At first I didn't know exactly what was goin' on, so I pulled on a side of the street to a Gas Station nearby and started checking everything; after seeing that all was "Normal", I noticed that everytime I touched the Brake Pedal, the idling engine looses its stability and acts like it has a Vacuum leak, first stumbling and then rough idling; also I can Hear said vacuum leak inside the Cabin, around the Pedal... I Did a small "Confirmation" test, I pumped the brake pedal with the engine off, then, keeping the foot on the brake pedal, I started the engine, in order to feel if the Brake Booster is working... and No, it is completely dead. After almost half hour, I managed to drive the car back to home, at very low speeds, with all my foot on the brake pedal... Seems like the many tests I did, some of them including "Stomping like Mad" on the Brake Pedal, have torn the rubber diaphragm inside the booster... shortening its lifespan... but it already has 15 years and more than 160K miles, and being automatic, the car relies more on the Brakes. Already I was thinking seriously about changing that Single Diaphragm Booster, intended for the 7/8" Master Cylinder; with a Double Diaphragm Booster, intended for the New 1" Master Cylinder, seeking to get Rid from the Stiff Pedal... so this situation only accelerated things up. Tomorrow I'll ask kind permission to my Boss, to not go to the office in the morning and I'll grab my Vernier Scale once again: I'll Hunt for a suitable Replacement Booster with Double Diaphragm; wish me Luck! Kind Regards.

Somehow, today's morning I started to feel the Brake Pedal on the Kia Sephia, more Stiff... Hmmm... Something seems to be going wrong...

Thank you! Yep! ... The Brakes has been already Tested in Many Situations, such as Dry Pavement, Sandy / Dusty Pavement, Gravel Roads, Unpaved Roads, Muddy Roads during Rain... Using Soft Braking, Medium Braking and Hard Braking / Stomping on the Pedal as Mad... and the Sephia stops nice in each situation as a Sephia could do. I mean the entire vehicle performs identical as it was before the Master Cylinder change, but now it has a much Taller and Responsive, but stiff brake pedal, which only needs to go in 25% of the travel, while before the Master Cylinder change, it needed to go 75% of the travel on the same average usage. I Hope that by Changing the Rear Drums with Rear Discs will improve braking performance by avoiding the Rear Wheels from Locking easily, since the Rear Drums are Oval, which somehow is "Normal" after 160K Miles / 15 Years of use in an Automatic Car. Also I'll get Rid from the Monthly adjustments to the rear shoes... Nope! Early Subaru EJ engines came with Factory Carburator & Distributor, up 'till 1994 (as you can see on a Link, posted at the Very First Post of this mere thread) but no Legacy nor impreza used an EA engine from factory, never. My "BumbleBeast" works awesome with his original EA82 Engine, which is Weberized; 300K miles and Rumbling strong, I don't need an EJ Swap 'cos it is not a race car. The Good Ol' EA82 is enough for my kind of driving; even lifted + 25" tires. More info clickin' on my Signature. Yes, Me too... Kind Regards.

Very Kindly, let me ask you... Why not change the Rims to wider specs, instead of using Spacers? Kind Regards.

This photo, is one of the very Few I could take in Costa-Rica, because after so many photos and videos taken on Nicaragua, the Battery on my Camera ran out of Power without any mercy, and the Charger was many hundreds of kilometers away, at home... So, I've learned a New English word (to me): "BLERCH" as seen in a Bumper Sticker, in a Costa-Rican Car, a prius hybrid; see: I found the explanatory website: Running On Sentences: The Blerch Kind Regards.

I'm really Glad that you liked them, Thank you for being here with me, This thread was some sort of Monologue... Kind Regards.

My Little Daughter took a Volcanic Rock with her, as "Souvenir" Here the Porous Black Rock, placed over the dirty "KiaStein" Kind Regards.

After driving for a while, from the Museum to the Mere Volcano, we reached the Top area where a Car could go, there is a Huge Parking Lot where you should leave your car and then go Walking to the Volcano's top. This is a Warning we saw at said parking Lot: This is the Volcano's Opening: Closer View: Another Perspective:
