Metal grinding noise in back wheel-Brake pads?
I have a 1995 911 Carrera with 13,000 miles. I recently developed what sounds like a metal grinding noise in the right back wheel. My guess is this is the brake pad indicator and I am scheduling service to replace the pad. Does this sound right? Could it be anything else like a wheel bearing?
Need to try to pinpoint as I live in a small town in South Dakota and must trailer my 911 to FT. Collins, Colorado. What a pain. Anyone help>?>? Thanks, Dave |

13,000 miles? I doubt it is a brake pad unless someone was doing some serious hard driving over those miles. My first guess would be a wheel bearing, my second guess would be a CV joint, although that is more of a clunking noise. Jack up the rear wheel and try and locate the noise/feel. Does it only make the noise when you are braking? Can you grab the top and the bottom of the wheel and feel any play? Oh and where do you live in South Dakota?

I would at the least take the wheel off to see how much pad you have left. It the pads are ok then your parking brake is dragging. Follow the adjustment proceedure in "101 Projects" and save yourself a lot of trouble.

Dave,
Sounds like it's time to learn how to look after your own car. Invest in a nice sturdy Sears floorjack and get a jackpad adapter (looks like a round hollow hockey puck with a nipple in the center costs $15) for the 993 jack point under your car. Loosen the wheel nuts and take off the wheel to inspect the rear brake pads. Easy to replace pads yourself in all Porsches. There is a big main spring in the center of the caliper which can be pinched out of its' retaining slot so it swivels up to allow removal of the pads. Take one out at a time and see if it is down to the metal backing plate.....often the source of a grinding sound when brake pads have been worn too much. Tom |

If you bring it all the way to Fort Collins (where I live), have Steve at Poudre Sports Car do the work. He is trustworthy and does a good job....
My opinion... Bill |

Dave,
Come to think of it most stock wheels on 993's have such ample openings that one can see the pads directly through the spoke openings at the calipers. Look for disc scoring and roughness or cracked rotor (cracks between the holes on the rotors). All this can be seen without removing the wheel. I use to feel for the thickness of the pad linings in situations where you can't get a direct line of sight. Hope it's just that or mayby some gravel got caught in the wheel and needs to be removed.
