Got a yamaha XS400 1982...
Front brakes works fine...just filled up the master cylinder with new brake fluid. Doesnt look like there is any leak but it builds up pressure and sometimes the brake gets tighter and grabs the disk way to hard... Doesn't lock completely but shouldn't grab that hard.
Any suggestion where it could be coming from.
I bled it yesterday to release the pressure but today again... it is a little too tight!
Thanks for your help!
