X-PRO^® Rear Hydraulic Brake Assembly for 50cc 70cc 90cc 110cc 125cc ATV
[220-999001]

Excellent. Work great. My 5 year old is strong enough to lock up his wheels on a 70cc atv. Needed to make one bracket out of an old piece of steel (cut to size with a grinding wheel and drilled 4 holes) and they bolt right up!
