Enough time has passed since the Rear Disc Brakes' Swap and after some Highway Travels and many city daily driving, including some unintentional Panic Braking to avoid accidents; I could assure that the "KiaStein" featuring all the Brake parts updated as I explained in previous posts of this Thread, now has an Outstanding braking Behaviour, using way less Space to Stop, and Without Lockin' the Wheels too Hard.
As I explained, the car needed these parts:
► Improved "Groveless" Proportioning Valves.
to avoid air getting onto the system / leaking brake fluid.
► Increased Bore Master Cylinder + Dual Diaphragm Booster.
to solve the "Deep Traveling" brake pedal, which goes even Deeper with Rear Disc Brakes, due to the increased Brake Fluid Chamber on the Calipers.
► Rear Disc Brakes.
to get rid from the noisy rear drums and their useless self adjusters, that lead the drums to do almost nothing, letting the front discs to bear almost alone with the vehicle's braking, with the consequent premature wear / warp of the front brakes.
Unlike the useless rear drum brakes, the Rear Disc Brakes' setup on these Sephias is Awesome; the only drawback is that the Parking Brake on the Drums is Stronger than the Parking Brake on the Discs. After the install I also cleansed and painted the front Calipers with same High Temp anti-rust ceramic paint; let me share a couple of Photos:
The Front Calipers:
(By the Way, here you can see the '03 Spectra T8D engine)
the Rear Calipers:
So now I can Assure that the Weak Brakes problem on my Wife's Kia Sephia, the "KiaStein" has been completely Solved, and if you review carefully this thread, you'll notice that the Kia Engineers did almost the same upgrades I did, on their Sephias that featured Rear Disc Brakes from Factory.
