Hey guys, my '93 VX-R is making strange noises from the rear brakes. It started out as a groaning noise when creeping slowly in other forward or reverse, then progressed to the occasional high pitch squeeling noise when driving at normal speeds.
I thought it was a stone in one of my brakes to I jacked the car up and took both wheels off and inspected the pads and rotors but couldn't see anything obvious. I put the wheels back on and with the handbrake off I spun each wheel. The left hand side would spin freely but would make a scuffing noise once per rotation or thereabouts - as if there is a high point on the disc rotor or something. I tried the right hand side and it was exactly the same, except the scuffing noise on that side was a bit louder and if the wheel was going slow enough it would bring the wheel to a stop when it reached the 'high point'.
Is this normal? The disc rotors are in good condition with no scoring and no lip on the edge of them. The brake pads both have alot of meat left. There's no play in either of the rear wheels and there's no constant grumbling/groaning noise so I doubt it will be a wheel bearing too.
I'm pretty sure it still makes the noise if I lightly apply the brakes too, so not sure how that's related (my mechanic asked if it made the noise while braking lightly).
I don't want to go ahead and replace brake parts if they aren't the problem, especially the rotors as the VX-R is the only model with these rear rotors (260mm ventilated). The rest either have solid (or drums) and the VR-4 has 280mm ventilated. The VX-R is not a common model so parts like these will be hard to come by.
Cheers for any help
