Question:

Jeep makes a brake system that is disc and drum brakes in one?

Has anyone else ever seen this? I was working on a 1998 Jeep Grand Cherokee. I removed the back what appeared to be brake rotors, and discovered that it has brake shoes under the rotor/drum/whatever you want to call it. The shoes are NOT the e-brake. They react with the brake pedal. It also has a caliper with pads on the rotor/drum/whatever. Has anyone else ever come across this? I was very surprised, and so was everyone I know. I believe it‘s called a disc-over-drum brake system.

Answer:

i think your mistaken .i think it's the e-brake unless you found another e-brake some wear else
The drum brake is the e-brake. It is common on many cars with 4-wheel disk brakes. Some cars don't have the disk and drum, but yours does.
the disc part is the hydraulic section that your foot uses, the drum part in the center of the hub section is the e brake. gm uses this also.
