Abs Brake Adjustment.

[tpunx99GSX]

Ok heres the deal. When i swapped my brake pads when i was in minnesota i think i fucked up a little, my car hasnt been the same since. Ive never had a car with ABS before so i think i messed with the adjustment and tightend it too much. first off i remember when i finished the job i pulled out of my driveway and started to accelerate to hear a loud scraping and very little power, the car was moving but when i let off the gas the car slowed down very fast. so i pulled back into the driveway and loosened the bolts i thought were the problem, still the problem exists that when i am at a stoplight i can let totally off the brake pedal and the car will not move, (remember im still an automatic at the moment) usually if you let off the brake the car will roll foreward. so im thinking that the brakes are still set too tight, and i think this may be causing my car to get horrible gas milage due to the added stress on the motor. Is there any way to adjust the ABS brakes so that they are to spec?

Did you open the bleeder screws before you forced the caliper piston back in?

[tpunx99GSX]

bleeder screws??? i dont think so

[LightningGSX]

Bleeder screws on the calipers.I don't have much experience with DSM ABS, but with others, its easy to damage valves in the ABS, if your not careful

Don't open the hydraulic system if you don't have to.

There really isn't any adjustments for disc brakes. did you put the pads in backwards? :stick:

But seriously... Unless you removed the hub/bearing I doubt you f'd up your ABS system. Unless you damaged the back of the sensor by bumping/hitting it with the caliper while you were messing around back there.

Actually on ABS systems you should always open the bleeders when you compress the caliper pistons back in.I've seen plenty of ABS damage by NOT doing so.

no the pads are not backwards, but like i said "first off i remember when i finished the job i pulled out of my driveway and started to accelerate to hear a loud scraping and very little power, the car was moving but when i let off the gas the car slowed down very fast. so i pulled back into the driveway and loosened the bolts i thought were the problem,"

I've never opened the bleeder to compress the caliper piston in my life and never had a problem. Just squeeze it with the trusty old ChannelLock pliers.

The sensor is in the hub/spindle on mitsu's, not in the caliper

The caliper slider bolts are not your problem Tom, I would retighten them. Did you check to see if your rotor backing plate/dust sheild is scraping on the rotor?

The position of the sensor has nothing to do with it, it valves inside(external on some vehicles) the ABS unit/pump that can be damaged by reverse pressure
