This automotive "how-to" guide was specifically written to assist owners of the 2nd generation 2008 to 2012 Jeep Liberty SUV in replacing the rear disc brake pads.

Owners of other Jeep, Dodge or Chrysler vehicles such as the Cherokee, Compass, Patriot, Wrangler, Grand Cherokee, Grand Caravan, Nitro, Dart, Avenger, Challenger, Durango, Journey, Charger, Town & Country, 300, and 200 may also find these rear brake job DIY instructions to be helpful.

The tools needed to complete this procedure include a floor jack, two jack stands, a lug nut wrench, a 13mm socket with a ratcheting wrench, a "C" clamp, a set of new rear brake pads and a 17mm spanner wrench or a pair of pliers.

A few compatible aftermarket rear brake pads include the following with their respective part numbers: Wearever PNAD1274, EBC DP61799, ACDelco 17D1274MH, Akebono ACT1274, Wagner MX1274 or QC1274, Bendix MKD1274, Raybestos PGD1274M, and Monroe # DX1274.

Pull Off Rear Wheel
The first step is to chock the front wheels to prevent the vehicle from moving.

Then slightly loosen the 5 lug nuts on the rear wheel with the tire iron by turning them counter clockwise, raise the vehicle with the floor jack and securely support it with the two jack stands.

Pull off the rear wheel to reveal the brake rotor, caliper bracket and caliper.

Loosen Caliper Bolts
Locate the two bolts on the back of the caliper and loosen them with the 13mm socket and ratcheting wrench.

If the caliper slider pin begins to spin as you try to loosen the caliper bolts, hold it in place with a 17mm spanner wrench or a pair of pliers.

Once both caliper bolts have been removed, you can carefully lift the caliper out of the bracket.

Rest the caliper on the rear suspension without placing any stress on the rubber brake fluid line.

Wear Bar - Bottom Inner Pad
Pull the old rear brake pads out of the caliper bracket and make a mental note of how the wear or "squeal" bar is situated.

The wear bar on this 2012 Jeep Liberty was located at the bottom of the inner brake pad.

Thoroughly clean off the brake rotor, caliper bracket, brake caliper assembly and the lug nut studs with a brake parts cleaner spray. Do not use compressed air or blow air with your mouth to clean off the brake parts since inhaling brake dust can be harmful to your health. Brake dust can be carcinogenic (causes cancer) if inhaled.

If your vehicle exhibits shuddering, pulsating, or vibrations during braking, you may need to have your rotors "turned" (resurfaced) or just replace them with brand new rotors. If this is the car's first rear brake job and the rotors appear to be in excellent condition, you should be able to just replace the pads with great results.

Replace Anti-Rattle Clips

In order for the rear brake caliper to work properly, the two caliper slider pins need to be well lubricated.

Pull the upper and lower caliper slider pins out of their rubber dust boots to inspect them. If they appear to be dry, apply a generous amount of a high pressure moly lubricant or "caliper pin grease". Re-insert the caliper pins back into their dust boots until they snap securely into place.

If your new set of rear brake pads came with new metal anti-rattle clips, remove the old ones and install the new ones at the top and bottom of the caliper bracket.

Compress Caliper Piston
In order for the brake caliper to fit over the thicker new brake pads, the caliper piston will need to be compressed backwards using a "C" clamp.

Before you begin compressing the piston, move to the engine bay and twist off the brake fluid reservoir cap. Removing the cap will allow the brake fluid to easily travel backwards through the brake lines.

Attach the "C" clamp to the rear caliper piston using the back of an old brake pad to evenly distribute the force across the piston. Repeatedly check the brake fluid level in the reservoir to prevent if from overflowing as you compress the piston.

Be sure to replace the brake fluid reservoir cap after compressing the caliper piston since brake fluid is hygroscopic (absorbs water).

Wear Bar - Bottom Inner Pad
Install the new rear brake pads with the wear bar situated at the bottom of the inner pad.

Press the new brake pads flush against the rotor and gently lower the caliper down into the caliper bracket.

If the caliper won't fit over the thicker new brake pads, you may need to compress the caliper piston back a bit further.

Insert Caliper Bolts
Insert the two caliper bolts and thread them a few turns by hand to prevent them from becoming cross threaded.

Tighten the caliper bolts with the 13mm socket and ratcheting wrench to just past hand tight or about 25 ft lbs of torque. If the caliper slider pin turns as you tighten the caliper bolts, hold it in place with a 17mm spanner wrench or a pair of pliers.

Double check that both the caliper bolts are tight before moving on to the next steps.

If your brake pedal previously felt soft or spongy, the brake fluid may be contaminated with water or the brake lines may contain some air bubbles.

It would be best to bleed the brake lines at this time in order to flush out the old fluid and replace it with fresh DOT3 brake fluid. For more on this topic, check out my Brake Line Fluid Bleeding With An Assistant DIY Guide or alternatively the Brake Line Fluid Bleeding With A Power Bleeder Guide.

Replace Rear Wheel
Replace the rear wheel and spin on the 5 lug nuts by hand to prevent them from becoming cross threaded.

Lower the rear of the vehicle from the jack stands and the floor jack.

Tighten Lug Nuts
Progressively tighten the lug nuts in a "criss-cross" or star pattern to about 1/4 to 1/2 turn past hand tight. It would be best to use a torque wrench or an air gun with a torque stick to tighten the lug nuts to about 75-100 ft lbs of torque.

Sit in the driver's seat of the vehicle and pump the brake pedal a few times to restore brake line pressure. Check the brake fluid level in the reservoir and verify that it is at the proper level.

To break in your new rear brake pads, just drive normally for the first several hundred miles while trying to avoid any hard or "panic" stops which may glaze over the new brake pads and cause them to be noisy and/or not perform as well.

It's also a good idea to regularly check your driveway for drops of brake fluid which may indicate a leak, check the brake fluid level in the reservoir, and also check that the lug nuts are still tight.
