It is possible that you won't need to change the rear brake pads on your Jeep Liberty as often as the front pads. Nevertheless, you should inspect the rear brake pads whenever you change the front pads. The brake calipers on the Liberty's rear wheels are slightly different than the front ones; thus, changing the pads requires a different procedure.
Open the cap on the brake fluid reservoir in the engine compartment. If the brake fluid level is at or near the maximum level, siphon out up to two-thirds of it using an unused turkey baster or similar suction device.
Raise the vehicle's rear end, support it on jack stands and remove the rear wheels. It will help to loosen the lug nuts with the tire iron before you raise the vehicle.
Wash off the brake caliper assembly with aerosol brake cleaner.
Compress the caliper piston using a C-clamp; the piston is located under the center arch of the caliper. Watch the brake fluid level in the master cylinder as you compress the piston, and make sure it doesn't overflow.
Remove the two mounting bolts from the caliper with a wrench; don't remove the banjo bolt for the brake hose. Swing the caliper up and remove it from the disc, and tie it to the coil spring with a wire.
Remove the brake pads from the caliper. Pry the outer pad out with a flat screwdriver; the inner pad is seated in the caliper piston with a prong-like retaining clip.
Remove the anti-rattle clips from the caliper's mounting bosses. Clean and reinstall them.
Install the new inner brake pad into the caliper piston using its clip. Line up the outer pad's protrusions with the slots on the caliper frame, and push the caliper in until it seats in the caliper.
Pull out the bushings from the caliper and clean them. Apply an anti-seize compound to the bushings and install them back in the caliper.
Reconnect the brake caliper to its mounting bracket--engage the upper end with the anti-rattle clip at the bracket's top end, and swing the caliper down onto the bracket. Install and tighten the mounting bolts.
Reconnect the rear wheels and lower the vehicle after changing both sets of brake pads.
Refill the brake master cylinder reservoir with brake fluid as needed.
Press the brake pedal multiple time until it feels firm to seat the brake pads.
