I did search and read through the posts on TT, what it appears is that you guys bought 2009 crf master cylender's. I see one on motosport brand new for $125 which i intend to buy, but my question is does anything else need to be replaced (brake line, caliper, calper bracket)? I would really prefer to hear from people who have done this already. Thanks

Initially I put on a I put on a braided brake line and that seemed to work initially, however after a few laps the spongy feeling resurfaced slightly but not as bad. Then put on over sized rotor and re blead the line and that did the trick, i only use 1 finger on lever now with good feel and ample stopping power.

I'll add the rotor is just a no name off eBay works well with new genuine pads no obvious sign of wear yet, about 7 hours MX.

I guess i will try that first but, i have never done anything like this before so like my original question does the caliper or caliper bracket have to be changed or adjusted to fit the oversized rotor?

I answered my own question on motosport the oversized rotor comes with pads and a caliper bracket, so now i have 2 more question the most importan why is a rotor a set of pads and a bracket $350 do you know of any cheaper ones and second when i have to replace the brake pads it "oversized" a standard size?

I use the EBC 280mm kit with a braided stainless line. Its touchy, but it still has some potential. I have heard that the 09 CRF master cylinder will help, but I am unwilling to TRY it for 150 bucks. Plus, its a Honda part....wouldn't it be smarter to just buy a full Brembo setup? Haha
