My 96' CR sat for a few years leaving the front brake dragging excessively. This spring I fit new pads, EBC rotors, cleaned the calipers/seal grooves, pistons and bled everything.

The brakes work well but still leave the rotors hot after a ride. With the front end raised I get about 1 1/4 rotation with a hard yank. Both rotors seem like they are the same temp after a ride so it would seem the pistons in both calipers are not retracting correctly.

Another weird thing is brake feel. At the lever I have a very light pull until the last bit of travel, which is firm and abruptly stops the bike. This might be normal for all I know, but linear it's not. In addition, before every ride I have to pump the brakes to get pressure.

To me it seems like the pistons are not hanging up in the seals. Could it be the master cylinder? What else should I check?

Thanks

I bled the system a few more times and brake lever feels seems to have improved.

For the non-linear play in the break lever - I would keep at it, you could possibly have some stubborn air bubbles or build up in there. I'd try another good bleed or two before looking at a master cylinder.

As for the rubbing - The combination of new rotors & new pads is most likely whats causing the contact/heat. The new full width (unworn) rotor and full thickness (unworn) pads could be approaching the max in terms of clearances.

What type of pads did you put in? This could be multiplied if you installed more aggressive (track/racing) pads. Eventually it will go away once the pads wear a bit.
