misalignment brake/caliper ..need help
Posted: Sat Sep 23, 2000 7:12 pm
Eric, I've seen bike mechanics struggle with this problem when changing tires on my KLR.( Happened to me once!) Now I sometimes explain to them at the start it is a lot faster when removing & reinstalling the wheel to remove the brake caliper first. It sounds to me that you need to fidgit with the positioning of the pads relative to how they fit into the caliper. If there is no longer a sufficient gap between the pads for the rotor to fit in, you'll never get it back together. You probably knocked the pads out of alignment when reinstalling the wheel or pumped the lever extending the caliper piston. Make sure the "stationary pad" is in the correct position, I think there is a trick with that part but can't remember without tearing one apart. Just like when you change old worn pads with new thick pads, remove the brake fluid reservoir cover to allow you to push the caliper piston in allowing more room for the pads. Caution:Don't allow any air into the line. Hope this helps.
