bronsen Posted July 25, 2007 Share Posted July 25, 2007 Hi, Can anyone tell me why my rear brakes are jamming up. The brakes work fine for several presses, but they slowly jam against the disc. The pedal travel is reduced and the pads seem to stay closed against the disc, not returning to there proper position. Which is causing the disc to overheat. Is it the master cylinder at fault or the rear brake calipar. Here in Australia, xs750 parts are around, but are extremly dear to buy. If I open the bleed nipple, the brakes return to normal, but slowly jam up again. Will putting a kit in either stop the problem. Would anyone know which is causing the problem - Master cylinder or the brake calipar. I would be most gratefull for any help. John Australia. Bike - 1976 XS750D Hi Again, Solved the problem. Rear calipar piston covered in old sticky brake fluid (Like glue). when brake was applied, the piston would move out, but was jammimg at a certain stage and wouldn't return back. Cleaned piston and inside calipar housing with a light coat of thinners and used a pencil grinder fitted with a nylon brush. Brakes are now working perfect.

chuck_zc Posted July 29, 2007 Share Posted July 29, 2007 May also be a collapsed brake hose. Had one give out on me last week in my minivan. Same symptoms. Crack the banjo nut at the master cylinder and see if the caliper releases. Link to comment Share on other sites More sharing options...
