Kaw. brakes locking up

[XFT LOU]

Hello, my buddies 02 kx 250 rear brake slowly locks up after about four laps. The pads are new the linkage works fine no dirt or mud, its a very clean and well maintained bike. This has been going on for about a year. We bleed it he even rode around not using or touching the pedel. Any suggestions ... to repair this bike.... not to start a yamaha buy post. Thanks

Usually that means the bleedback hole in the master cylinder is stopped up

kawi's are just prone to PROBLEMS!!!

ye sounds like either a master cylinder problem or possibly the piston in the caliper could be dirty and not returning properly

make sure there is some free play in the back break pedal. if there's not, it will drag heating the fluid and causing it to lock. this is very common if they are out of adjustment.

Yep, M/Cyl. Happened on the biggest POS I ever rode, a 4 speed YZ450F.

Check the floating caliper pins, make sure they are greased. Then check the pins the brake pads hang on, if they have any grooves in them, replace them.
