I just noticed that when I firmly apply my front brakes, the left wheel slow/locks up prior to the right wheel. I bled the brake lines and the same still ocurs. The right wheel calipers do apply pressure and stop the wheel. Just wondering if they should be more in sync?
Is this really a problem?

 

So you can actually feel the P650 pull to the left? I never heard of this before. As for being a problem, it will probably wear out the left side pads if they are doing most of the stopping. I guess you have taken the calipers apart for inspection?

 

no sir it didn't pull to the left. I just noticed the left wheel locked up. The bike stopped straight. I am guessing this is not an issue to worry about. Like you said, the left pads may wear a little faster. I may pop off the right caliper on a rainy day and clean it out.

 

Prairiedude, have you had any prior issues with the front end? Have you ever busted a CV joint or anything like that? I busted a front Cv joint and when it cut loose, the axle flew up and hit the caliper. It bent the mounting bracket to the point where the caliper was forcing that front wheel to brake harder than the other wheel. If you've ever wedged a stick or something in there, it might have done the same thing.

 

this might be a long shot, but it happens to cars when they get older. it is possable that the rubber brake line is swelling shut. brake fluid has an effect on rubber after a long period.

another long shot, your left caliper. your piston might be rusting in the bore and causing a tighter fit.

this has happened to me on cars. i know the quad is only a couple years old but you never know. maybe a bad batch of hoses or a bad seal on the caliper.

 

I think I fixed the problem. I removed the right brake caliper last night, removed the pads and pistons. Blew compressed air through the caliper. Cleaned it out good. Reassembled and bled the brakes. Now both brakes stop pretty much equally.

 

so i wasnt that far off, with the caliper. i hope it works out for you.
