hey guys, im new to this site and i really need some help. i just purchased a 2002 zx6r with only 2600 miles on it. it had been in a light accident so i need some plastics. anyway, ive repeatedly bled my brakes and every time i move3 the bike, forward or backward, i hav to pump the lines up again. it just goes dead after about 5 feet. ive inspected the pots and they are not leaking. the rotors are not warped at all. thanks for any advice, josh nance

One of the bleeder screws might be damaged, you might have a bad master cylinder seal, or there might be a crack in the line somewhere that you can't locate. Maybe the seal in one of the calipers has blown.

Its entirely possible that the brake failure is what caused the accident that it was in.

I'd concentrate on the master cylinder, though. It might have been damaged in the accident, and is sucking in air, ,but seals well under line pressure.

What I would do is pump up the brake, and tie the brake lever to the handlebar for a while, and see if there is a fluid leak that becomes visible, or if one caliper lost its grip on the rotor. That would help locate the problem area.

BC.

I know you said the rotors aren't tweaked at all, but if there are no leaks anywhere, my bet is on the rotors....

I'm betting on the rotors too.........had the same thing happen to a friend of mine.....

hint:remove rotors when removing the front tire from rim, when using tire irons!!

Might help.
