Default 78' Wheel Squeak

I have seen this subject before and have tried a few things related to a recurring squeak I hear possibly from passenger side rear wheel. Doesnt squeak at first while driving then appears. Stops when I apply brakes. I have new rotors, pads, and calipers but still have the noise. I tried putting lubricant behind pads between caliper but still there. Anymore ideas?

Possibly a wheel bearing/? rotors that need cleaning since new components installed? Jim

Did you bed your rotors when you replaced them? If not, search on the net for that term, there are lots of opinions out there on how it should be done, but all are similar.

I have had 2 C3's and on both cars when I got a rear wheel squeak it was the 1/2 shaft u-joints in both cases

Ok so wheel bearing would stop squeaking when brakes applied?

I did follow the instructions that came with the rotors and pads. The squeak was there before and after rotors and pads were replaced

I sprayed white grease or Teflon spray on the u joint and drove the car. The squeal went away or lessened briefly enough to determine that was the cause. Then I replaced the u-joints.

Just had the same thing on my wife's 78. Both outer half shaft u-joints were toast. I replaced all four and everything is good again.

Just under 70,000 miles. The right side was making a squeaking noise and the left side, after heating up was making a snapping sound like you were tapping a hacksaw blade on a metal table. The needles on the left side were binding and broken up. If you are doing it yourself, it's also a good idea to use a flange reinforcement plate to keep from distorting or bending the flanges when removing the joints.

Checked the half shafts and u joints and they looked ok. I drove it until squeaked then quickly jacked up but still couldnt find the problem.

see if you happen to notice any excessive brake dust around that wheel.
could be a partially collapsed brake hose. that will sometime not let the brake fluid return. the noise from this type of problem would be very minor.
