my problem is that the rear wheels do not block with my escort, I have tried it already on races but no chance. even with full pedal pressure the wheel can be set up, with effort, still with the hand dream and that on both sides behind. I have already opened the brakes and could not detect anything, no oil, brake cheeks io, and the wheel brake cylinders are also running. if I put on the hand brake only a raster to block the wheels and can also not be used with all can someone tell me how to do this that I can only achieve a minimum braking effect in the rear? mfg rigo56
