Rear Brakes Problem

[inman91]

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.

I have not seen an aftermarket yet.....
I have seen a guy make a bracket to make a honda work , but it appeared to lock up too easy for my tastes. just buy the rebuild kit and replace the o-rings inside ( if you are capable) if not order the kit , remove your master and take them to a hydraulic shop,
( after they are done laughing) they will charge you alot less than a Dealer

Woodward specialties used to make a killer, all-billett setup for the hondas and YFZ's. Worth a try, I had one on my YFZ.
