My bike(s)

Found 1 result

  1. 2002 Le Mans with 23K miles. While the front wheel was off for a new tire I decided to clean the calipers. Still connected, pads in, I brought a bucket of water with a little dishwashing liquid up to them and scrubbed with a nylon bristled dish brush. No drama. How much water would they get during a ride in a rainstorm, right? Once reinstalled they pumped right up but as soon as the bike moved the brake lever went to the bar. I bled them, same thing. Bungied the lever back overnight, same thing. Bled the M/C, same thing. The lever gets pressure but loses it the moment the wheel turns. So - removed the calipers, emptied the system, removed the pucks one at a time - all looked and felt fine, although a couple had feint striations of lighter color I couldn't feel. Buckets were perfectly clean. Seals felt fine to my finger and didn't show any visible damage. Reassembled everything using brake fluid as lube. Same thing: Lever pumps up and holds until the bike moves. The odd symptom is the lever pumps up to perfect - and stays like that - until the wheel goes a few rotations. Then all bets are off. I've done loads of brakes in decades if riding without problem so I can't call this one. Anyone know what's going on?
