Intermittent failure under hard braking....lever comes completely in intermittently...once or twice, not every time he rides though..happened to me when loading on truck once too :scream: ....no leaks...no air in syst...changed fluid, master cyl. guts, pads... Suzuki says no reported problems...the intermittent part is the problem , it won't do it when needed to...any opions short of changing master cylinder housing, then line , then caliper??? THANKS

Sorry on this one. No trouble here. Is caliper binding anywhere...just a thought.

really sounds like the master cylinder to me. you replaced the plunger I take it? Maybe the bore is out of spec? Shouldn't be considering its so new.

Are you using DOT 4 fluid, not DOT 3? Is the fluid new?

Check to make sure that the rotor isn't bent. This happened on our KTM 65. Put the bike on a stand and spin the wheel slowly. When you find the bent portion, use a crescent wrench and bend it which everway it needs till the brake works correctly.

also double check you master cyclinde and caliper for any possible leaks.
