Hi, the problem your having sounds like you need the brake servo replacing this is a common problem on all makes of car and the cause is the servo.
The servo is the part under the bonnet that has all the brake pipes going to it and it also goes to your brake pedal these are not that expensive to buy but can be difficult to fit as you have to undo all brake hoses and pipes then when you fit new one you need to make sure the pipes are fitted correct else they will leek and also once the new one is fitted you will need to bleed the whole system at all four wheels to ensure their is no air left in the brake line.
Once this is replaced you should find you have no problems and then your brakes will be as good as new.

The only other problem to cause air in the brakes is if the back brakes are not disk then you need to remove the hub and check the brake cylinder that pushes the shoes onto the hub when braking but if your car has disk brakes on the back as well as front then i would replace the servo.
Hope this is some help to you let me know how you get on or if you have any questions ok

broken wire on harness? I have had troubles in the past with this kinds issue. remove wheel, brake caliper, rotor and you should have access to the sensor. most time they are connected with a allen bolt. remove abs sensor and you will find a fuzzy metal like stuff on it. Like draging a magnet on the dirt, sometimes just cleaning it off will do the trick. the fuzz interferes with signal and set off the code. Here is were its your choice ether clean it off and reinstall or replace with new sensor.

Right back brake locks up 1993 pontiac grand am


Make sure there is nothing leaking onto the brake shoes. Also, make sure that the emergency brake is dis-engaging and the cable isn't hanging up. If the original wheel cylinder had been leaking, the brakes may need to be replaced if they were contaminated. Also check that the drum itself is round. If not, the shoes will lock the wheel when they are on the high spot. An easy "backyard" way of checking the drum is to move it to the other side. If the problem moves to that side the drum is out of round.
