2002 saturn L100 brake problems
 

hello folks i am a retired person (Translation old f#rt) on a very limited income
i have a 2002 L100 2.2L and the breaks are driving me crazy
i had to replace the brake lines going to the rear being one ruptured
then the rear left brake cylinder went bad (the piston was completely out of it)
i replaced it and in just a few days it went bad
i replaced it 3 times and it keep blowing the last time i replaced it i replaced the springs and pads with it
now i have that line capped so i can drive it
now one of the front brakes as a twisted caliper mounting bracket
someone said that it maybe a faulty proportional valve sending too much pressure to one wheel
did an internet search and could not find any mention of that
however i have been told that some cars use the ABS control to regulate break pressure
does anyone know if a 2002 L100 has a proportional value or if it is handled by the abs unit?

• please treat this as a desperate plea Because it is

Sorry that I can't help you, but I have heard that there are adjustable proportioning valves out there that people use on hot rods. I have no idea how the hell they adjust them, but maybe DD or Bones will, if they read this. I don't even know if your car has ABS on it or not. If so, I suspect you'd see the ABS module mounted on the brake lines near the master cylinder. Can you post a photo of the firewall and master cylinder area?

It dose have the abs module with traction control

Okay, I'm not that familiar with the modern ABS systems. I'm an old fart that's used to working on drum brakes and disc pads on the front of the car. The whole ABS thing just pisses me off because that's just another computer controlled something to go wrong with a car nowadays. I miss the emergency brakes on the drive shafts like I had on my 48 Plymouth in the days of my youth.

I dont believe it has a proportional valve per se.
The ABS unit takes care of that.
I find it hard to understand how the piston can come out of the wheel
cylinder if the brake shoes are correctly adjusted.

Are you putting pressure on the brake cylinder before the springs and shoes are all in place and the drum back on?

I don't believe the average the caliper mounting bracket can be physically twisted. They are likely cast and functionally would be most resistant 2 distortion perpendicular to the length of the piece.

The only way I see a caliper mounting bracket bending is as a result of an accident. It's going to throw the alignment of the pads to the rotor off and then who knows what braking pressure is going where?

I would not expect adjustment of a proportioning valve even if there was one would make any sense as you don't know which way you're trying to adjust what. The solution is to fix the existing issues Ias opposed to determining temporary workarounds. Unfortunately, that costs money or bartering with a good friend who knows cars.

Could you please post a picture of the twisted caliper bracket?

Are you sure you got all of the springs back in the right place on the rear drum brakes? Watch this video by richpin and make sure you have it put back together correctly. If you left out the self adjuster or didn't get the shoes properly seated in the notch of the wheel cylinders, you'll have problems.
