What tool is used to remove the brake pads for Jeep Grand Cherokee 2001 8 cylinder 4x4

10 mm socket to remove the caliper slide bolts, a decent sized screwdriver to pry the caliper up off the rotor and a large "c" clamp to drive the piston back into the caliper housing so the new pads will fit over the rotor. Use an old pad over the caliper piston when driving it back in so you don't damage it, be careful not to pinch the piston boot under the new pad and make sure the slides move and that you use some grease on the slide bolts when putting them back in. Also be careful not to cross-thread the pins when re-installing. After you have finished, step on the brake a few times to get the pads into position and remove any excessive clearance. If you don't open the hydraulic system, no bleeding is necessary.
Rears are more complicated so get a haynes or chilton manual for that.
