I just plan on changing the pads. Whenever you release the brake aren't the pads supposed to release the rotor a bit? I took the caliper off, turned on bike and pumped the rear brake and the brakes just closed up all the way. When I release it the pistons would open up 50% of what they just closed. So every time I pressed the brake pedal they came closer and closer together.
Yes, but just enough to where the rotor spins.Whenever you release the brake aren't the pads supposed to release the rotor a bit?
There's no need to turn the bike on, the brakes are not power assisted.I took the caliper off, turned on bike and pumped the rear brake and the brakes just closed up all the way.
??? Not supposed to do that.When I release it the pistons would open up 50% of what they just closed.
Exactly, that's what they're supposed to do, but with the rotor between them. It's when you release the brake lever and the calipers don't release at all and the pads maintain constant braking pressure on the rotor that you have problems.So every time I pressed the brake pedal they came closer and closer together.
I usally use brake cleaner spray and a toothbrush before EVERY pad change.Take the top off the master reservoir and take out about half of the fluid. It should be easier to push back the pistons with the top off the reservoir. You should probably clean the pots before you try pushing them back in. Use some brake cleaner or WD40 and wash it off after. Then push in the pots.
But I want to wrench on my bike though, so thanks for all the input fellas. Sounds like all is good I just need new pads
Hey......!!! We both live to the same city Athens by name only.You're in Ga ....I'm in Greece.Your point is good , but very rare to happen on a bike JMOIf you haven't figured out your problem yet, check your brake line. Pull it off and try and blow through it from the caliper side to the resevoir side. The inside of the brake line could have colapsed on you which will cause the brakes to apply, but not let the pressure back to release. I had this happen on my moms truck, she could apply the brakes and stop, but the driver front wouldn't release. The inside of the rubber line had collapsed. Changed line, bleed the air out and she was good to go. Just something to try.
