1995 Ford Ranger rearend locks when brake applied

if it was on one side then i would sy check the rear brake. with both sides i wonder if the master cylinder is realising. try jacking it up in the rear. Turn the wheel by hand and have a friend put the brake on. Then release the brakes. If the wheel then turnes free then check the rear brakes themselves. If not then have the master cylinder checked.

You might want to make sure the rear axle seal isn't leaking.That grease will fet on your pads and make them lock up.I had the same problem.

Remove drums. If no grease or brake fluid leaks, then resurface drums on a lathe. Purchase Motorcraft brand brake shoes and install.

I had this exact same problem. Switched to Motorcraft shoes. Turned drums; problem solved.

Also had this problem with a GM minivan. Turned drums, purchased/installed AC-Delco brand shoes. Problem resolved.

Ford/Motorcraft shoes simply have the correct friction material to work with the iron composition brake drums. Spend the extra $$ for Motorcraft. It'll be worth it.

This is a known issue. Google the problem. there are sites that sell all the TSBs. they tell you how to solve it. I have just lived with it. It happens in the cold, or on wet and foggy mornings. I don't mind but think my neighbors may have.
