How do you Unseize motorcycle brakes?
Gently pump the brake lever (without pulling it right back to the bar) while watching the action of the pistons. They should come out then return very slightly. If they don’t return, or you can’t push them back, the piston may be partially seized. Don’t panic, in 99% of cases, we can deal with this easily.
What causes a motorcycle brake caliper to lock up?
You need to leave some room in the reservoir for the brake fluid to expand when it heats up, otherwise it will expand into the calipers and push the pistons out. Fill to just below the max line. Or you just have air or water in your lines that is expanding with heat and causing the lock up.
Why are my brakes bleeding in my BMW?
Besides regular maintenance brakes bleeding, another problem has been that the owner that pays little attention to anything but the fluid level in the master cylinder. That level should normally DROP over a long period of time, as the brake pads wear, & it takes more fluid in the caliper to fill the space the piston previously occupied.
When do BMW front brake pads start to wear?
It is entirely possible for pads to wear, & the fluid level NOT go down, due to accumulated water! THAT is hardly ever discussed. In general, BMW front brake pads tend to wear VERY SLOWLY, and the rear DISC pads tend to wear much faster.
Why do BMW front brakes wear faster than rear?
In general, BMW frontbrake pads tend to wear VERY SLOWLY, and the rear DISC pads tend to wear much faster. Some of this is because of the rider’s habits, but even with good use of the brakes, the faster rear wear is normal. It is my guess that part of this has to do with position (dirt]
What causes the brake to lock up on one wheel?

This video will give information on how to test each of these components in order to get a better idea of what is causing your brake problem.
