Rear Brake Pedal Suddenly Stiff and No Braking Power
OK, just took a trip to CO after having recently replaced seals in the rear caliper and bleeding the system. Also replaced rear rotor and one of the front ones, as well as pads all around. Cleaned and lubed caliper parts as well.
So everything seemed pretty good with my braking system throughout most of the trip, but then on maybe the last day the brake pedal started feeling weird. Like I'd push it and very little braking power would result. If I jam it really hard the bike dives forward as if I'm squeezing the front brake (probably because the front piston is activating and working well).
So I thought maybe there was some gunk in the system, blocking brake fluid from getting to the rear caliper pistons? Today I jacked the bike up, spun the rear wheel, and pushed the pedal. It did stop the wheel from spinning -- so at least something is happening with that caliper. Then I figured I would bleed the rear caliper some more, and then see if that helped. Did that and went for a test ride, and the problem is still there.
Any ideas about what might be causing this? All this brake stuff has been a learning experience along the way, but man, this is just one thing after another.
