Spongy front brake

(1/2) > >>

jasbadboy:
Has anybody any tips on getting a good response from a front brake. My brakes are dia compe 901's via a hollow stem bolt and it just seems really spongy and slow to respond. It is also difficult to get the calipers to pull in equally on both pads.
Is this just due to the routing of the cable? Does it reduce performance when you cut the cable length?

if your cable loop coming out of the bottom of the fork crown area into the brake is too tight then it reduces performance...try and get as big a loop as you can without it looking dumb...



personally I never use a cable guide on the forks ... just use a cable tie and leave it as loose as possible.



take the cable out squirt some WD40 down it and see if its any better... always works for me.

Ed sort it out, running your cable through that purpose designed cable guide is hardly going to reduce the stopping power you may already have!?!?!  ::)

Well Rob... in my opinion ( IMO ) it does help so I posted up what works for me.

Its a much tighter line through the cable guide...it a bitch to get in ( and out ) and fooks up the cable. The way I have it is a better curve for the cable and is easy to do... especially when you are setting up a new bike and might need to take it on/off a few times...and the brake works perfectly.

so  :P

 :D

901's were never designed to be used on a Potts Mod conversion, DC introduced the 880 for that purpose.  You'd probably be better off trying to get an 880 or maybe one of the later DC Nippon / Bulldog brakes.
