Rear disc brake issues

A couple years ago I bought a rear disc kit from Master Power( never again)
I got parts i couldn't use, had to have the rotors machined etc, etc.
The problem is that every once in awhile the pads keep rubbing after braking and going around a corner.Its a pretty embarassing sound.Looking in the FAQ's one solution might be to eliminate my c-clips, eliminating side to side play. Any other ideas? I'm ready to start another kit if I have to.Thanks !

Re: Rear disc brake issues

I don't think therer are too many of us that have done this conversion judging form hambone1958's posts...

Disc brake pads are supposed to gently rub against the disc. The vibration of the rotors gives them the clearance that is required. In your case you may have defective disc pads. I have bought some pads before that had so much metallic imbedded in them that it sounded like it was grinding metal on metal. I exchanged them for a different brand and took care of the problem.

It may also be that yours are not retracting fast enough. I'm sure you replaced all of the rubber hoses including the one on top of the rear axle going to the frame. But, if you didn't those old rubber hoses will swell up on the inside causing restricted flow. In other words, fluid will flow under pressure to the brakes, but is restricted or slow to return causing the brakes to "grab" until it slowly returns to the master cylinder...
