Francis thanks for your help and time bro , my MRX4-R is about a year in a half old with about 30 races on it and tons of weekend play time the brakes started to fade away 2 races ago so I bought some new pads but still had the problem, I know it could be a # of things but thought I would come to some Mugen Bro's for some help. Again thank and I will try the yellow and black pad combo.
