Check for a frozen wheel cylinder:

When inspecting the rear brakes, tap the brake shoes with the palm of your hands back and forth.Don’t tap too hard. Only tap hard enough to ensure that the brake shoe link pins are moving freely.

If they move freely, the wheel cylinder is still working. If they don’t move freely, you have a frozen wheel cylinder that you should replace.

Checking for leaks:

To check for leaks, pull back the dust boot to inspect the bore of the wheel cylinder. If brake fluid drips out of the bore, you need to replace the wheel cylinder. In this case, we noticed the dust boot was ripped and fluid was escaping from the rip. Therefore, we will have to replace this wheel cylinder.
