My KLX suffered from a terribly insufficient front brake and I bought a new rotor, pads and a master. Tried the pads first and no change. Then put the new master on, going from the stock 13mm Nissan (rebuilt once) to a 13mm Brembo and VIOLA! Front brakes are powerful enough for a two finger stoppie even without positioning or trying to do a stoppie! I think I will send the rotor back, but not sure cause it does look real cool!
