rc30sp1 Posted June 18, 2009 Report Share Posted June 18, 2009 the front brakes on my sp1 seem to be binding. if you lift the front and spin the wheel it may only spin one revolution. iv rebuilt my calipers,replacing seals,fluids, and pads.iv also goodridge hoses fitted. the bike feels fine on the road any ideas. thanks stephen.

Cibbersicks Posted June 19, 2009 Report Share Posted June 19, 2009 When you rebuilt your calipers, and fitted your new seals, did you use red rubber grease to lubricate the seals so the pistons slide nicley? Link to comment Share on other sites More sharing options...

Cibbersicks Posted June 19, 2009 Report Share Posted June 19, 2009 no It's obviously not absolutely essential, but it may well be the cause of the impromptu binding of which you speak.... Link to comment Share on other sites More sharing options...
rc30sp1 Posted June 19, 2009 Author Report Share Posted June 19, 2009 i cleaned the pistons and smeared brake fluid over seals before rebuilding. the brakes have been doing this for a long time not just from the rebuild. Link to comment Share on other sites More sharing options...
David W Posted June 19, 2009 Report Share Posted June 19, 2009 It's a long shot, but could the rivets on the discs be full of brake dust and not letting the disc float? They get bunged up and need cleaning now and then by turning them and spraying brake cleaner into them. Link to comment Share on other sites More sharing options...
rc30sp1 Posted June 20, 2009 Author Report Share Posted June 20, 2009 mmmm will give that a shot. i think i should oil my disks,that might help seriously i think i will try all of above,it cant hurt. Link to comment Share on other sites More sharing options...
Mr.Pigdog Posted June 20, 2009 Report Share Posted June 20, 2009 Before you installed the new seals did you clean the seating area?often they bind as corrosion builds up behind the seal and 'pushes' it making it grip the piston and hence bind.

roadracer Posted June 20, 2009 Report Share Posted June 20, 2009 Those Honda brakes are known to be a little "bindy", even when hot, but my guess is it's not even a brake issue-but a front wheel alignment issue. Try loosening the pinch bolts and axle bolt, then re-tighten axle to torque spec. Take the bike off the front stand and bounce the forks up and down a couple times with the brakes on to align the calipers and discs/seat axle properly, then re-tighten the pinch bolts to torque spec. The brakes will be much less bindy when hot, but you won't get perfect drag-free brakes like brembo's HPK kit, for example. Apply a brake contact cleaner to the discs as well, then wipe off with a clean rag to finish the job and remove any contaminants. Another cause may be that the pads are contaminated, but if they're clean and new (with the caliper rebuild...) I doubt that will be a problem Link to comment Share on other sites More sharing options...
rc30sp1 Posted June 21, 2009 Author Report Share Posted June 21, 2009 wiil try that but iv no torque settins as iv ohlins forks and machined spacers to suit. by the way the brakes were binding on standard forks also. Link to comment Share on other sites More sharing options...
Cibbersicks Posted June 21, 2009 Report Share Posted June 21, 2009 Hey RC30SP1 have you read the other thread? Have you checked your discs with a dial gauge to see if they are running true? The slightest of run-out on them will cause the brakes to bind/stop the wheel from freely spinning. HTH Cibbers Link to comment Share on other sites More sharing options...
