My rear disk brake is driving me crazy. Can anyone assist in directing me to what to do with this?
The situation is that these are Hayes So1e brakes. Hydraulic. The pad that they call "inner" which is closest to the hub seems to be stuck open and will not engage the rotor. When I brake it just presses the rotor the that side but does not engage the pad because it doesnt extend. I tokk it off several times yesterday and messed around without really knowing what i was doing. Its seems like I can get it to act properly but once I tighten down the adjuster thing it just locks up. Does it need to be bled?
How old is the system? Has it been rebuilt? (nevermind...from the questions above, I can deduce the answer to that)
May have a sticky piston.
Here's what I did one time to free a piston:
1. Push both pistons all the way in...like "retracted" in not "clamped" in. (leave pads installed and use a tiny "flat bar" or broad/flat metal prying device.
2. Put metal flat thingy between the pads (where the disc rotor goes) and hold firmly against the pad/piston that's working properly.
3. Have a buddy gently pull the brake lever while you impede the movement of the functioning piston. This should cause the other piston to move.
4. Let up on the lever and push pads all the way back to the retracted position.
Do this a couple times and lube the pistons with Hayes compatible brake fluid. If sticky piston persists, have the caliper rebuilt or buy a decent set of hydraulic disc brakes.

If I'm understanding this correctly, it wouldn't work. The Sole only actuates from one side.
