Hey everyone,

I just installed my Tyga muffler and carbon chain guard and my rear wheel was moving fine when it was on the stand. I was testing my brake lights so I slammed my rear brake pedal twice and now my rear brakes are locked on. The rear brake line is routed okay (no kinks) and the pedal isn't stuck at all.. Any ideas??

I put new rear pads in recently but I've done about 400kms since then and never had a problem using my rear brakes.


Cheers

I'm not an expert on brakes, is it really locked on or just binding? Will it let you pull away? Are you sure there's no kinks in the pipe? Tried bleeding it?

Do you have a return spring on the rearsets? Can you manually close the m/c? Just get the brake off the hanger and have a look. Might well want to be bled and serviced..

When you put the pads in, you didn't clean the piston up properly and now over time the dirt on the pistons catches in the seals, and you get a seizing cailper. Strip, clean, rebuild.

I bled them about 4-500kms ago. Definitely no kinks in the hose.

Yeah the pedal goes back up but the brakes are still locked on so I guess this means the piston is stuck and can't come back in. I bled the system and gave the pistons a real good clean when I did so, but they were in pretty bad condition so I guess the pistons are stuck now

Will do.

Can you move the bike forward or backwards

take it off the hanger then open the reservoir cap and the bleed nipple and then wiggle the caliper till it comes off had a similar problem on a mates gixxer and it worked

good luck
