Rear brakes on 2000 explorer need to be replaced, this I can do. My question is - what is the problem when brake fluid is coming out of one of them. Need some help on the cause, and what else I will need to do to fix it.

 

If it's brake fluid look at the caliper,hose or steel lines.Sounds like it could be axle lubricant also,is it coming from inside the rotor?If so you will need axle seals and parking brake shoes.Let us know what you find.

 

You're going to need a wheel cylinder, so replace both sides. When you get the drum off the wheel cylinder will be easy to find. Replacement consists of disconnecting the braake line from the back side and removing a couple of bolts (after getting the brake shoes out of the way). Do one side completely at a time so that if you loose your place you can refer to the other side.

When you get it back together (both drums on), you'll need to bleed the system.

 

Oops, I was refering to drums. Does it have disk brakes in the rear?
