Sticking brake pedal - SV650.org

21-01-11, 05:13 PM

Hi all,

The trouble Im currently having is that when the brake pedal is pressed (has to be very hard for it to work) it does not return back up again. Have checked and both springs are still attached.
Was working fine (but still needed alot of pressure) until the rearset was bent when the bike was knocked over. So my thinking is that now the rearset is bent it is stopping the pedal from moving freely?

From reading the haynes manual, would loosening off the footrest holder bolt create a little more room for the brake pedal and possibly enable it to move more freely?

Thanks
Dan

I wouldn't loosen off any retaining bolts as these are of a set length for the job they do. check the master cylinder is still in alinement, if the carrier is so bent it's not you may get away for the interim by using longer bolts and spacers on the mastercylinder mount, and the pedal moves without physical impedance, then if that's OK, check the caliper is in a serviceable condition (this maybe why you have to push it so hard). but this in no way means you shouldn't replace the damaged parts as soon as you can.

Cheers Mark.

Could maybe be your caliper piston seals because they act as a self return, just a thought though.

I'm also experiencing the same problem, so i'm quite curious, i'd just put it down to the pedal not being used as the bike's barely been out recently!

Try stripping the lever off and greasing it up.

Happened to me last year

Yeah, i've tried to, got the rearset off no bother, but couldn't get the single bolt that holds the pedal to loosen up... i'd seen a few warnings that they were made of cheese so I have exercised caution!

You'd need to get the rearset off the bike, minus the brake system

put it on the ground and use a decent length allen key, it should release it a bit effort

+1
did mine a few days ago, same method to get it undone
brake pedal is all lovely now, just remember not to loose split pins and put washers back where theyre supposed to do you dont have to take it apart again, its a reasonably simple job though

Another thing liberally grease up the bearing metal of the lever

Thats tomorrow evenings plan then. Is a particularly difficult job to remove the brake components from the back of the plate?

PS, sorry for the hijack, but hopefully the responses will benefit the OP too!
