Hi All,
I just finished putting on rebuilt rear brake calipers done by PMB. Also, new braided steel brake lines and set of new Textar pads on all 4 wheels (1975 914). I took it out to do the “bedding” break-in process and I noticed it was pulling to the right. So, (after doing cool down slow driving)when I got home I checked temperature of rotors. Both back rotors were about 125 degrees. However front right was about 240 degrees. BUT front left was only about 85 degrees. To a novice like me seems like front left is not working. Any suggestions on diagnostic procedures or what to check out. Thanks PDXBob |

Rear brakes are damn hard to get hot enough to "bed" in using street driving as the front do most of the work anyways.
Having the fronts operate as they are on your car would stop me from trying to bed anything. Fix the fronts first and then worry about bedding pads. All the suggestions have been good. I have another... Do the proper bleeding, make sure both sides squirt equal amounts out of the top bleeders. Re-check the rear pad adjustment, this does need to be correct. Put both front tires up in the air and spin test them. Both spin free, have an assistant jam on the brakes and release. Both spin free- you have something way weird going on. One stays locked up? Break bleeder free. Squirt like a bitch? You have a restriction in the system. Old lines are a common culprit but yours are new. If it's holding pressure against the caliper, you can slowly move up the system releasing each fitting until you find one that's not under pressure. Your restriction will be between the last pressurized fitting and the un-pressurized fitting. No squirt from locked caliper? Send your front calipers to PMB for the same treatment you just had done to the rears... |
