'98 Rear Disc Brakes
I replaced rear brake pads recently to find the driver side worn out while passenger was in decent condition, like half life on that side. Now maybe 2 months later the driver side is growling when brake applied and intermittent noise while driving. Not always, and periodically the noise will go away if I tap the brake lightly. Thinking I have a bad caliper on the driver side brake? Any help confirming diagnosis or other things to look for extremely appreciated

I had this just other day, did new brake pads all around and had front rotors cut. Week later passenger rear was getting hot from just short trips, other 3 rims cool. Bad caliper- when I disconnected brake line from that caliper I could not even get it to retract with a large “C” clamp. Replaced, had buddy help bleed air, all good. So I guess if you removed it from rotor, leave fluid line connected. Remove cap under hood to fill it. Put a “c” clamp to it and see if you can get it to go back in. Then, replace cap on fill under hood, press brake pedal and see if comes back out some? History for me over 20 years has been when bad they just don’t release (aka: retract). |
Thanks Trukntigger, researched through many posts here and came to the conclusion I'll just replace the caliper. Inspect the flex line and do pads and rotor while it's all apart, maybe get a rebuild kit and go over the caliper after the fact to develop another skill!

I would do the line before the caliper. Could save money

Hi , sorry to hear that you have had these brake pad problems
From my experience with brakes from the late '70's , if the pads on one side are more worn than the other , or even the inboard side being thinner than the outboard side , than there's a strong possibility that the piston is hanging up in the caliper bore , and not retracting enough . Confirmation by not getting flush into the caliper when using the c-clamp .

You can rebuild it for $15-25 including the phenolic steel piston, square seal and boot if you mix and match on Amazon. Bonus points for not dealing with a deposit or having another caliper sitting in the shop collecting dust. Even saw a nice video where the guy pumped the brake to push the piston all the way out instead of disconnecting the line and using an air compressor on the bench to shoot the piston out... If you have a helper that's quick with the line clamp, you won't even loose that much brake fluid AND have an easier time bleeding it afterwards. This is my next step in 'bringing back the brick' pedal for my 99. Left rear pads were a hair away from being metal on metal on RR had about a 1/3 left. To me, changing the lines are a bigger hassle with more chances to break/twist a hard line.

Thanks for the input, pulled it apart after I had everything there to completely replace any or all components. What I found was the caliper was hanging up, C-clamp had great effort to get it to retract, flex line looked good with no issue there. Installed new caliper, rotor, and pads, works like it should. Doing another inspection this weekend to ensure the caliper is operating correct and flex line wasn't contributing to the problem.

Yes, exactly what seems to have been the issue. Replaced the caliper, checking flex line to ensure no issue after some use
