Bike is a 2012. Riding and started getting a bit of wobble after some heavy braking. After getting the bike home and taking a look I came to the conclusion that my front rotor had begun to warp. Yesterday I replaced pads, rotor & did a fluid flush. I go for a quick test run just around the block. I'm lightly braking just to seat the new pads and rotor. I stop at a stop sign and as I begin to pull away I notice the brakes stay firm enough to make the front of the bike sag while I begin accelerating and the lever seems stiff. I pull back in the driveway and my brakes are HOT and I'm unable to push the bike in neutral. I'm thinking my caliper may be the culprit but I'd like a second opinion. Is there something I might be missing? The piston pushed back in no problem when I was putting the pads on and I greased the pins before reassembling. If anyone can help or just guide me in the right direction it would be appreciated. Thanks.

 

Anyone?
FWIW I tried cracking the bleeder to free up the front wheel but no luck still tight.

 

how does the pin look? any damage. sand it smooth and regrease

 

Hey thanks for the reply. Been busy but had time today to pull my caliper off and take a look. After removing the pads I pumped my front brake to find that the front piston was stuck shut. I pushed the rear piston in and used a screwdriver handle to block it so I could force the front one out. No marks or pitting of any kind but decided to clean both pistons up anyway only to have the same problem with the front staying shut. Any advice on what to do from here? Does the front caliper need rebuilding?
