Just did the brakes on my car. Now I am getting a knocking sound that is speed dependent and it goes away with any kind of pedal pressure, but then comes right back. I have tried manually spinning the rotor to try and locate the sound but I don't seem to be able to get the speed high enough. Everything looks to be in the right places and I lubed the caliper pins at the same time. Anything I might have missed?
Can you detail what you actually did for the brake job? Routine Rear brake job: Check wheel bearing condition Turn rotor Inspect caliper seal and piston surface Inspect brake lines Inspect cable Clean all parts Replace pads Lubricate required parts Check fluid Replace wheels and torque lug nuts
I would at least pull the wheels off and make sure the wheel disc is there and look over everything than re install and torque um up! Sounds like you did every else? If you were in the neighborhood I would say run it by and have a look see....but...:smile5: FYI You should always turn the rotors when replacing brake pads.
Also... a speed dependant knock may be from crap being between the rotor and the hub, slapping the caliper back and forth. Is the metal spring well seated? Are the caliper guides tight? Do you have slotted rotors? I'm betting you take it all apart, clean everything up, and put it all together, and the sound goes away... Matt
Are you sure you got the new pads properly clipped onto on the pistons in the caliper - if you just slid them into the caliper, that's your problem. All you have to do is remove the pad and install it correctly.....those springs on the pads slip into a groove around the end of the piston
Well the knock is gone today so I believe, as the good Dr O has suggested, it was only some debris or a caliper slide sticking. Thanks for the help.
Ok......sorry to bring back the dead, but the noise came back earlier this week. Finally got the chance to get to the rear brakes today and guess what, the pad had come off of the clip on the drivers side. Good call Minidave !
You know what was weird.....it would only knock for a day or two then it would be quiet for days and days. It only made noise 4 or 5 times since the OP and it always happened early in the week. And by the time the weekend came around it was quiet, so no need to try and figure out why (and I usually forgot about it by then.....). Until this last time.....lol. Started making noise on Fri. so I remembered to finally check it out.
