Lastnoel Posted March 16, 2019 Share Posted March 16, 2019 Got a good deal on a nice 87 GL Wagon 4WD 1.8L engine and am trying to get it solid again. Brakes - it seems to have a leak from the unit located under the master cylinder that is the hill locking device. Can I just remove it from the system and plug the line that goes to it from the Master cylinder? There are a number of vacum lines that plug into the air cleaner that may not be hooked up correctly. Looking for a good diagram that shows where each goes ( what it does). The AC has been removed. Also looking for a good source of parts, new or used. Thanx!

FerGloyale Posted March 16, 2019 Share Posted March 16, 2019 you can remove the hill holder, but you must replace it with a "T" The brakes for Front left and rear right go through it. If you simply plug it off you will have no brakes at those 2 wheels. As for Vac lines......yeah......uh many have little "orifice" restrictors in them, so don't just toss them willy nilly. Best diagrams sare from the 86 FSM. Though when the 87s came out there were a couple changes.....and they were never noted in the 87 books.....Carbs were being phased out so they barely even mention the carb system in the 87 FSM. There was big corporate restructuring at that time too.....so 87 is a goofy year for a lot of stuff. Many of the Vac lines are not needed. Can you post any pics? we can maybe direct you to what needs to stay and what needs to go. 1 Quote Link to comment Share on other sites More sharing options...
Lastnoel Posted March 17, 2019 Author Share Posted March 17, 2019 Great, thanks for the feedback. From what I can see, the line from the master goes out and through the firewall, then comes out again and goes to the hill holder unit - with this info I will do some more investigating. Thanx! Good point on the 87 being different - found that the distributer is from an 80 Brat! Let me brake (no pun intended) out my camera and see what kinds of pics I can get. Stay warm and dry up there in the NW . . . we had one day of high wind, a little rain and the sun is back out. Quote Link to comment Share on other sites More sharing options...

Thanx! there are 2 separate circuits in the brake system. 1 cicuit goes out of the master out of 2 ports near each other, 1 line to pass front, 1 line to driver rear. The other circuit, comes out of a single port as one line, then splits going through the hill holder. The lines through the firewall are just the "out" lines to the proportioning valve, then on to the rear wheels. they don't come back up front.

Lastnoel Posted March 18, 2019 Author Share Posted March 18, 2019 Thanks again, I now know where the two lines thru the firewall go and will not deal with them. Got an old Haines (the new Chilton is next to useless) book from the guy who sold me the car and it is very helpful. I talked to a service manager at the local dealer who validated my idea to first disconnect the cable from the clutch that goes to the unit so it does not operate the valve when the clutch is pressed and check how much fluid I am still leaking, if a little, I can live with it (checking the reservoir periodically). If it continues to be a problem, I will put a T in place of the unit and by pass it all together which should solve the problem . . . Thanx! Gotten more of a handle on the Vacuum lines and will probably rebuild the Carb as I am having additional problems ( hard start, bad idle, low mileage etc.). Trick will be to get the number off the carb to make sure the kit I order is correct. You observation on the weird auto year (87) seems to be true and gives me a heads up on what I need to do to get the correct parts. Do you have a good cheap source for these older models? At any rate, it is starting to make sense with your input being important . . . thanks again Owe you a hot bath in the local springs if you ever get down here to southern NM Quote Link to comment Share on other sites More sharing options...
greg454 Posted March 19, 2019 Share Posted March 19, 2019 My hill holder was also leaking. I removed the cable years ago and it has not leaked another drop. Quote Link to comment Share on other sites More sharing options...
DaveT Posted March 19, 2019 Share Posted March 19, 2019 keep an eye out on ebay for a factory service manual. It will likely take a while, but they are worth it if you find one. Quote Link to comment Share on other sites More sharing options...
Lastnoel Posted March 20, 2019 Author Share Posted March 20, 2019 Thanks for the follow up. Disconnected the cable and it seems to have fixed the problem. Will certainly keep an eye on the reservoir for a while. While monitor ebay, thanks. Quote Link to comment Share on other sites More sharing options...
Lastnoel Posted March 23, 2019 Author Share Posted March 23, 2019 Got the hill holder issues resolved and I would like to rebuild the carb. Seems to have 2 different carbs that came with it. Is there a straight forward way to determine which carb it is? This is that weird year when many parts where different from the book. Finally, checked with my local parts house and they did not have rebuild kits for any of the carbs listed with that year/model. Is there a good source for older rebuild kits or a direction where to start looking? Quote Link to comment Share on other sites More sharing options...
FerGloyale Posted March 23, 2019 Share Posted March 23, 2019 (edited) 87 will have the Hitachi. "walker" make a kit with teh correct parts. FWIW, it's not nessecary to really replace everything in the carb. Just pull and blow out the emulsion tubes, and replace the tiny o-rings that seal the air horns to the venturi passages. Maybe pull the drain plugs ont eh bowl and clean the bowl out too. Edited March 23, 2019 by FerGloyale Quote Link to comment Share on other sites More sharing options...
Lastnoel Posted March 24, 2019 Author Share Posted March 24, 2019 Thanx, I 'll give it a shot. I can get the 'O' rings locally. Quote Link to comment Share on other sites More sharing options...
Subarule Posted March 28, 2019 Share Posted March 28, 2019 Replace the Hitachi with a Weber and you won't have vacuum line nightmares. Quote Link to comment Share on other sites More sharing options...
