What else could be my problem with my brakes?

Asked by Kurt Jul 20, 2022 at 10:59 AM about the 2000 Pontiac Sunfire SE

Question type: Maintenance & Repair

Ok my brakes went out completely so I

checked around and found fluid all over a

wheel hub on the rear drum brake. Found out

it was a wheel cylinder and I changed it. Got it

all together and tried bleeding from that wheel

filled fluid but the brakes are still not working.

It gains pressure but not barely any brakes.

Sounds like you still have air in the brake lines, you may have to bleed the entire system, start with the farthest first. As this has ABS try bleeding with the key turned on, and make sure you check the antilock motor assembly for a bleeder also.

If the master cylinder was dry then you may have to bleed that separate ( bench bleed ) . They make fittings to go on the master to do this and things need to be tight so that no air can get inside the fittings or tube . I open the bleeder and stick a piece of hose on it going up ward so that air will rise and not go back in . Depress the peddle only a few inches , nice and easy . You don't need a helper this way and you avoid all the " open , close " back and forth . For a completely empty line I disconnect it from the master , put a piece of hose on it and use a bulb syringe to load it up . Yes . all this is a P.I.T.A.
