I'm experiencing a problem with the brakes on my 1994 Jeep Grand Cherokee. I replaced almost every component of them over the course of the 2 years. Most of the replacements occurred in April 2012, because of problems similar to what I am having now.
Front brakes: (disc)
- In April 2012, Replaced all pads and rotors
- In Mid-2011, replaced caliper on driver-side disc brake
- In Mid-2010, replaced caliper on passenger-side disc brake
Rear brakes: (drum)
- In April 2012, replaced both sets of shoes
- In Early 2011, replaced both drums
When I completed the repairs in April 2012, all of my brake problems completely went away; the car stopped perfectly. This lasted for about 3-4 months. Symptoms started popping up again in August. When braking, even a light tap on the brakes can cause the car to start to skid, even after the brakes have been in use for 10-15 minutes.
It feels like it is the drum brakes locking, but I don't know for sure. Do the self tensioners sometimes over-compensate and need to be backed off? One more useful piece of information: back in August when the brakes began manifesting problems, it felt as if the brakes were catching due to uneven areas (while applying the pedal slightly, you could feel a drag-spin-drag-spin on the vehicle.)
** EDIT **
Two other things to note:
- The tires are only about 9-10 months old. Plenty of tread, 5-6K miles on them at most.
- The skidding can happen at VERY low speeds, even under 5 mph, while barely depressing the pedal.
