I have 04 foreman 4x4. The right front brake began squeaking and eventually locked up. I noticed the hand lever was so tight I couldn’t pull it so I bled the caliper and it worked fine, for a while but after a week or so I noticed the hand brake getting stiff and the brake was squeaking again so I bled it again. Worked fine for a while. This has continued for a while so does anyone have an idea what’s going on?
