On a rm 125 when you first pull the brake lever the brakes grab, but if you keep holding it the lever leaks off, and the front brake releases.

Does this mean the master cylinder needs to be rebuilt?

Thanks for all replies

If there are no external leaks on the line or caliper, yes it is probably the master cylinder.

Or it may just need bleeding to get the air out. I'd try that first then move on to the cylinder like 1500 said.

Sounds like the seal in the MC. air would feel spongy on the pull. I think rebuild kits are fairly cheap.
