The rear brake master cylinder on my 450X must have blew a seal or something in it because when you push the brake lever down, it slow the rear tires then just completely gives out. i know its not because of the rear pads, i know its not low fluid, or air in it, because i had fluid changed and my father who did it has been an atv and car mechanic his entire life, but my question is, i race XC in the Iowa series, and i was wondering if there is an aftermarket master cylinder out there, not really wanting to buy the oem part, after the problems i seem to have with the rear brakes.
