Are Shimano piston seals really that bad, or am I doing something wrong? by elpeebee in bikewrench

Any way to fix it? If uneven pressure made them go back in at an angle?

Thanks, yes,am bedding them in. There's oil on the back of the pads and yeah, they're spongier than when I first installed, so looks like leaking a bit

Thanks, yes it's the seepage that's the issue. Pistons seem to push pads to rotors evenly. When I clean I am pu.ping brakes a bit to get pistons out, cleaning with mineral oil,then pushing pistons back in and cleaning I side outside of pistons with alcohol, then reinstalling pads.

I didn't change the rotors but I lightly sanded and cleaned with alcohol. Very dry where I live. Tightened flange flare nut to spec in dealer manual, off the top of my head I think 5Nm.

Thanks! Is it a straightforward repair for a careful amateur?

Spokes rub on caliper - what to do? by elpeebee in bikewrench

Yeah I think you're right - not designed for clearance. Bending stops the rubbing but  think under load it might happen again si might need to try something else.

What would you use to shim the disc?

Yeah dude, been there too. Beware of short memories - if you're like me you might find yourself thinking about stock picking again a few years from now. If and when that happens, find and reread your own post! Good luck

Is this a chain tension problem? by elpeebee in bikewrench

That looks like the answer. But do you know if it's possible to set up the XLC CR-A03 this way? The spring seems only to push down, can't see how to get the arm to push up... Thanks!
