Brake Noise
Everytime I apply the brakes I get a rubbing noise from the right rear.
CVs are new, rotors and pads are 5K old. Only makes the noise when I apply the brakes. Could this be wheel bearing or e-brake? Thoughts? -g ------------------ Geoff Baltz '86 944 Turbo http://www.ninefiveone.com |
Well, since you only get the rubbing noise when you apply the brakes, and you didn't mention if you get a pulse in the brake pedal or a shimmy in the steering wheel; and it is only on one side, and considering everything else is fairly new, you might have a caliper that is freezing/sticking.
Pull the rear wheels and see if there is a significant difference in the pad thickness between drivers and passenger side (they should be pretty damn close to one another.) If you have a frozen caliper, you can get a rebuild kit for about $20. The only downside is having to bleed the system when you are finished. another possibility is a warped rotor (not likely since you say they are new) At that point, since you already have the wheels off, now would be a good time to adjust the parking brake - the rear wheels should just barely turn when you have the lever raised to the second click.

Is the noise constant or does it have a frequency like the speed of the wheel. Once I had a slightly bent hub which I thought was a warped rotor. It took me a year and several rotors to figure it out.
Raise the rear of the car, take off rear wheels, start engine, put in 1st gear, and let out clutch. Put a light under the rotor and look at where the top of the pads contact the rotor. Watch gap to see if it opens and closes a lot. Or if you have a dial indicator, you can measure runout. I think the book specifies 0.006 inch maximum but you should check that number. Also put something on the ground really close to the end of the hub nut/thread to check its runout. It should turn true. Had I done that at first, it would not have taken me nearly a year to fix the problem. And don't get your tie wound up in the rotor! Some pads just make noise. I use PF pads (93) and they are noisy. |
