1988 Isuzu Trooper. Disc brakes in the rear.

Parking brake is probably only working about 10%, which means, it's not working!

I get under the car, tighten it up, and it's still not working. If I tighten it too much, it becomes VERY difficult to pull, and even when I do, it still doesn't work!

I watched as my wife pulled the e-brake and I can see the springs move, I can even see the pads moving slightly to apply a BIT of pressure, but I can still easily turn the wheel...

When the brake pedal is pushed, they work fine. Anybody know what's going on?

 

did you take the disc off to see the pads and the ajusting piston if the pistion is closed open it a bit at a time untell you find the place you want worked for mine.

 

hmm.. does that piston adjust both the e-brake AND the brake when I push the pedal? So are you basically saying I need to 'reset' it? I think it adjusts by turning it clockwise/counterclockwise, but I didn't try.

 

let me know if that helped you...trooper76
