I have a 1980 RX7 that I purchased with a GSL-SE third member and GSL axles/brakes.

There is a passenger side rear end noise, kind of a "woop woop woop woop woop" noise, as I gain speed it gets faster but not noisier. It happens on both acceleration and deceleration, seems louder at lower speeds and on left turns. If i touch the brakes or the parking brake, it goes away until the brake is released.

I have had the brakes apart many times, it happened with the old pads, and with the new pads. I pressed on new wheel bearings TODAY and am still having the problem. The driver side caliper is new, the passenger caliper (the side that the sound comes from) is not, I have been able to screw in the parking brake on the caliper, but it definitely takes effort. I plan on replacing that caliper, but don't have the funds yet...

From my description, does anyone have any ideas of what it may be?

Check your brake rotors for runout.

Yeah, sounds like a warped disc...

Well, hopefully its not what happened to me... I thought my bearings were going out, turned out it was a bent axle, which was pushing the caliper down and making the noise. Took me 4 weeks to find someone willing to part with an axle.

guess; bent rim,bad tire,bad brake rotor,bent axle,exhuast rubing, wide tire rubbing. that should be good to start.
