Anyone else added the quad-brakes yet? I put them on and it stops on a dime, but it acts erratically by having a pulsing feel when slightly applied. I thought that one of the rotors was warped, but both front and rear does it. It sometimes holds when off throttle and sometimes it doesn't. I had a clutch fail and I now think that the brakes were applied slightly that caused the clutch to overheat and fail. When engine off and chassis rolling with transmitter on, it rolls freely...I am also trying new springs while waiting on Mugen springs and I am currently trying Ofna gray clutch springs. Are these stiffer than stock? They seem to be. I also think that it may take the brakes some time to seat themselves as they wear in the pads. I checked the linkages and it seems to not have slop or excessive play. Any help would be greatly appreciated.
