Replace the masyer cylinder where you put the fluid in,it could be inoperatable in the rear sylinder.Also replace the remainder of the rear lines you havent,the lines could be pluged expecialy if you live in a high moisture or cold climates where moisture can get in and rust inside the lines if it has set for any period of time. All of this will cost you around 30-50 buck if you can do it your self

Just changed front brakes now have slight pull to right. no steering whel play or extra pull on breaking, where should I start in diagnosing


Did you remove all rust from caliper and pad abutments
(sliding surfaces) ?
Did you put anti-seize on those parts, that need to slide
and be protected from future rusting?
Did you machine the rotors?
You don't put new pads on worn rotors
Did you bleed all 4 wheels (flush)
The right side is pulling because you most likey
have a caliper not completely releasing.
Sounds like you put the problem in there

Got a 94' chevy 1500 having brake problems, and replaced the master cylinder and bled the lines. but the pedal is still not working right, the pedal when pushed with the truck running will just go to the...


With he engine running your pedal action is assisted greatly by the brake servo. The servo is a large diaphragm that is acted on by the suction delivered by a vacuum line from the the intake manifold. The fact that the pedal goes to the floor when the engine is running just shows how much assistance the engine suction provides to your foot pressure. It is obvious that you still have air in your system. I would suggest that you top up the master reservoir, start your engine and pump the brakes quickly until you feel some hard back pressure. This will ensure that the brake pistons have been fully extended. Starting with the most remote caliper (right rear) bleed off about half a pint of fluid. Ensure that no air is allowed to **** back in via the bleed nipple at any time. Refill the master reservoir. Next the left rear caliper, bleed off about a quarter of a pint. Refill reservoir. Bleed off a about quarter of pint from both front brakes. This should sort it out.

We changed the disc pads on a 2001 silverado we had to open a brake line.we bleeded the brakes now we cant get the pressure back at the pedal.any suggestions?


When you bleed your brakes you have to start at the wheel longest distance from the master cylinder keep bleeding and putting fresh fluid in until fresh fluid comes out the bleeder screw do this by pumping brakes real slow tighten screw. do this at each wheel working your way closer to the master cylinder. The point of doing this is to replace old fluid and if done right you get all the air out of the brake system. You still have air in the system have you tried to put the lid back on your brake fluid reservoir and pump your brakes to the floor they should get tight unless you have a lot of air in the system. you mave have to do each wheel again just to get the air out.

Pull to the left, Brakes


Sounds like it was pulling before the brake job...if so the only thing you didn't replace was the rotors, I assume you turned them? and did you see hard spots on the rotor? discolored area that didn't cut the same......switch the rotors left to right and see if the problem moves or just replace them if they've been cut twice.
