not all brakes work on the front, the proper, fly rear brakes, bicycle union, superstar, demolition all wont work due to the angle of the part where the cables hook into is facing downwards causing the cable to rub on the arms
dia compe ad990's, textro's and oddy evo's will work fine as the arms are angled up slightly where the cable runs through as not to rub on the brake arm
( i run a evo 2)
