Rear Brake Locking Up!

[Matthew04833]

I have a Lifan in which the rear brake locks up quite frequently. Any solutions to the problem? We've tried adjusting the brake adjusting bolt... Please Help! Thanks!

Make sure the reservoir is not overfilled.

Run a search, your problem is not new.

Look in the DS prep thread.

Ok, Dad and I have figured out the deal on this. If you look at the bottom of your rear break master cylinder (not the slave at the wheel) you will see where the armature pushing in has two linkages with a bolt and two nuts for adjustment. Well, even with the nuts in the lowest setting where the linkages are both resting on the top nut, the master cylinder armature is still being pushed into the master cylinder creating some pressure. So, you will need to permanantly remove the nut between the two linkages and shorten the bolt (a grinding wheel may work well) so that the two linkages are touching. This will allow the master cylinder armature to release all the way out. We believe it's not necessarily a design flaw, but more of where the weld ended up for the bracket that holds both the rear foot peg bracket and the master cylinder. If this bracket weld had been about 1/2" higher the master cylinder armature would be allowed to extend all the way out with the stock bolt and nuts adjustment.

I had to adjust the pushrod part of the master cylinder out some. After I did that I have not had a problem.

Took about 5 minutes with hand tools.
