My car is a four door LX, rear drums, non ABS.
This fall I believed I had a failing brake booster. My brakes would work normal sometimes and other times I would need to pump them. I never knew when to pump so somtimes I would give too much brake and end up looking like a newby driver.
I performed a booster check that was outlined in my Chilton manual as well as a vacuum check valve test. check valve passed, booster failed.
I thought I could live with it a bit more. But once winter set in, locking up the brakes when the booster worked, proved dangerous on ice.
So I bought a new booster. Along with it I bought some pads and shoes and drum brake hardware. I figured I might as well while I was at it.
Installing the booster was no fun, but I did it. And afterwards my brakes felt great. I drove around the block a few times and it seemed as though I fixed my problem. Nothing feels better than that. I was lovin it!
I pulled into my garage and performed the booster test again to be sure. The first step is to depress the brake pedal several times to make sure there is no change in pedal height. Well, while doing that, all of a sudden, the pedal gives and goes to the floor. Urrrg!!!
No pedal!!! I start the car, try pumping, and I get nothing!
Long Story... please stick with me.
After sleeping it off and doing more research i inspected some things.
No leaks to be found, under car or under hood.
I cracked open the drums and replace the shoes and hardware.
Found a bad wheel cylinder on the drivers side, so I rebuilt it.
Started to bleed the system.
started at the rear drivers side, then front passenger, then front driver.
at the front driver, no fluid or air would come out unless I had my assistant continually pump the pedal.
at that point I stopped out of frustration, cold, and a broken finger.
my plan was to try and bleed from the passenger rear today. and maybe figure out how to adjust the rear brakes without taking the wheels off. My manual says something about an adjuster located on the inboard side, underneath the control arm. I'm not sure what the inboard side is... Hopefully it will be clear once I look at it.
Anyway, I'm kinda stuck just stabbing at things. I'm learning as I go. I'm thinking that I have to adjust the rear brakes, bleed all the air, and possibly flush the brake lines somehow? Alot of IDK's. Fluid being bled is also very very dark and dirty.
Please, the more ideas and suggestions. the better. Gotta baby coming this spring and need to get my car back on the road.
