Dodgy Knees Posted May 26, 2020 Share Posted May 26, 2020 There's a simple fix here somewhere... take it all apart and wheel off and reassemble taking your time. Pay close attention to spacers, caliper movement, disc alignment. Piston/pad movement. Grease where necessary. Check if it all goes tits up when axle bolt tightened. Don't rush the job. 5 Link to comment Share on other sites More sharing options...

If it worked before the wheel was removed and then doesn't work anymore when reassembled, the answer is somewhere in the assembly. 1 ***2015 Candy Red FJ-09*** Link to comment Share on other sites More sharing options...

When you had the wheel off to change tires, did you remove the sprocket carrier /cush drive from the wheel? The sprocket carrier separates from the wheel and has the rubber dampers inside, separate it from the wheel and re-seat it, make sure it is fully inserted in the hub. 1 ***2015 Candy Red FJ-09*** Link to comment Share on other sites More sharing options...

Nope, didn't touch anything past the sprocket. So everything is back in place. Chain is adjusted etc etc. No brake grabbing, rubbing or grinding but I haven't hit the pedal yet... 10, 9, 8, 7, 6..... And failure! Back piston won't release. Bike for sale! Lol Edited May 26, 2020 by hammer Cheers! Link to comment Share on other sites More sharing options...

Lol Finally, a voice of reason, sell that crap. I don’t know but it’s possible that you have a bad caliper, I mean that never ever happens right? No way they could make a bad one or it just happen to go bad when you changed the tire......nope, completely impossible. Link to comment Share on other sites More sharing options...
hammer Posted May 26, 2020 Author Share Posted May 26, 2020 I'm totally stumped now. Bled the brake with no air. Wondering if something happened when the pedal got pushed down with no rotor to grab? Cheers! Link to comment Share on other sites More sharing options...

Lol is this with the caliper bolts installed? it still looks like your brake pad is not sitting parallel to the rotor. something is wrong somewhere here..... are your caliper pins bent? the caliper shouldnt just lock up like that with a tire change. EDIT: if you rotate the wheel with the caliper off, can you see any waves in the rotor side to side? Edited May 26, 2020 by trevinator Link to comment Share on other sites More sharing options...
hammer Posted May 26, 2020 Author Share Posted May 26, 2020 Bolts are in, no wave. Just might look off due to the angle. Ordered a piston kit and new pads. Hopefully they're in this week. Cheers! Link to comment Share on other sites More sharing options...

Is it possible that the first assembly was off kilter and damaged the piston/caliper on first hard use? That first set of photos showed the caliper not sitting quite right. Could be worthwhile taking the caliper apart to inspect for damage. Anyway... curious to know what you find, and good luck with the repair.

My thoughts exactly. When you noticed that the bike feels harder to push around the garage after reinstalling the wheel, that would have been the time to stop, investigate, disassemble etc. At that point things might have been reversible. Taking the bike for a spin and stepping on the brake lever may have been what caused the real damage. Any time you perform work on the bike and something seems slightly amiss after it would be best to not ride until all things are put back to normal. 1 There is nothing like spending a day riding with friends in the grip of a shared obsession.

com3 Posted May 27, 2020 Share Posted May 27, 2020 Sounds like the rear master cylinder valving might have gone sideways... Most likely due to installation error (spacers on the wrong side, or maybe you didn't seat the sprocket carrier well enough) when you put it back together....and if the caliper was binding and you rode it anyways, it got real hot and boiled the fluid...thus damaging the piston seals as well. 1 Link to comment Share on other sites More sharing options...
