🔧 Grand Cherokee - Rear Brake Pads and Rotor Replacement

This repair replaces the rear brake pads and both rear rotors on your Grand Cherokee. The rear parking brake uses small drum-style shoes inside each rotor, so the parking brake must remain released while removing the rotors.

Difficulty Level: Intermediate | Estimated Time: 2-3 hours

⚠️ Safety & Precautions

• ⚠️ Work on level, solid ground and support your Grand Cherokee with jack stands. Never work beneath a vehicle supported only by a jack.
• ⚠️ Release the foot-operated parking brake before removing either rear rotor.
• ⚠️ Chock both front wheels because the parking brake must remain released.
• ⚠️ Brake dust can be harmful. Do not blow it away with compressed air.
• ⚠️ Do not press the brake pedal while a caliper is removed.
• ⚠️ Never allow a caliper to hang from its rubber brake hose.
• ⚠️ Brake cleaner damages paint. Wipe spills away immediately.
• Battery disconnection is not required for this repair.

📋 Before You Begin

• Park your Grand Cherokee on level pavement, select Park, switch off the engine, and release the parking brake completely.
• Place wheel chocks firmly in front of and behind both front tires.
• Open the hood and inspect the brake-fluid reservoir. If it is near the MAX line, remove a small amount before compressing the caliper pistons.
• No infotainment service mode or scan tool is required because your Grand Cherokee uses a pedal-operated mechanical parking brake.
• Complete one side at a time so the assembled side remains available as a reference.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Rear Wheel Nuts

• Use the 22mm deep socket and 1/2-inch breaker bar to loosen each rear wheel nut about one-half turn.
• Do not remove the wheel nuts while the tires are still supporting the vehicle.

Step 2: Raise and Support the Rear

• Use the 3-ton floor jack at the approved rear lifting point to raise your Grand Cherokee.
• Position the 3-ton jack stands beneath the approved rear support points, then lower the vehicle onto them.
• Give the body a gentle push to verify that it is stable before proceeding.

Step 3: Remove the Rear Wheels

• Use the 22mm deep socket and 1/2-inch breaker bar to remove the wheel nuts.
• Remove both rear wheels and place them flat away from the work area.

Step 4: Remove the Rear Caliper

• Use the 13mm socket and 3/8-inch ratchet to remove the upper and lower caliper guide-pin bolts.
• If a guide pin turns, hold its flats with the 15mm open-end wrench while loosening the bolt with the 13mm socket.
• Lift the caliper from the bracket and support it with a brake caliper hanger hook.
• Do not twist, stretch, or kink the brake hose.

Step 5: Remove the Old Brake Pads

• Use the large flat-blade screwdriver to lift the inner and outer pads from the caliper bracket.
• Use the large flat-blade screwdriver to remove the old stainless-steel abutment clips. Abutment clips are the small metal guides on which the pads slide.
• Note the orientation of the wear indicator before discarding the old pads.

Step 6: Compress the Caliper Piston

• Place an old brake pad against the piston, then use the single-piston brake caliper compression tool to press the piston slowly and evenly into the caliper.
• Watch the brake-fluid reservoir while compressing the piston. Remove excess fluid with clean shop towels if it approaches the top.
• The rear piston presses straight inward; it does not need to be rotated.

Step 7: Remove the Caliper Bracket

• Use the 18mm socket, 6-inch extension, and 1/2-inch breaker bar to remove the two caliper-bracket bolts.
• Remove the bracket and set it on a clean surface.

Step 8: Remove the Rear Rotor

• Confirm once more that the parking-brake pedal is fully released.
• Use the Torx T30 bit socket and 3/8-inch ratchet to remove the rotor retaining screw.
• Pull the rotor straight off the hub.
• If the rotor is rusted to the hub, use the 8-ounce rubber mallet to tap around the rotor hat.
• If the rotor moves outward but catches on the parking-brake shoes, remove the rubber access plug with the large flat-blade screwdriver. Use the drum-brake adjusting spoon to retract the star-wheel adjuster a few clicks, then remove the rotor.
• Count adjuster clicks for easier reassembly.

Step 9: Inspect the Parking Brake

• Use the safety glasses and a small nylon cleaning brush to inspect the parking-brake shoes, springs, and adjuster.
• Replace contaminated, cracked, loose, or excessively thin parking-brake shoes before installing the new rotor.
• Use brake cleaner and shop towels to remove loose dust. Do not use compressed air.

Step 10: Clean and Install the New Rotor

• Use brake cleaner and shop towels to remove the protective coating from both friction surfaces of the new rotor.
• Use the wheel-hub cleaning brush to remove rust from the hub face. The new rotor must sit completely flat.
• Slide the new rotor over the parking-brake shoes and onto the hub.
• Install the retaining screw with the Torx T30 bit socket and 3/8-inch torque wrench. Torque to 12 Nm (106 in-lbs).
• If the parking-brake adjuster was retracted, use the drum-brake adjusting spoon to return it by the same number of clicks. The rotor should turn with only slight, even shoe contact.

Step 11: Prepare the Caliper Bracket

• Use the large flat-blade screwdriver to remove any remaining old hardware from the bracket.
• Use brake cleaner and the small nylon cleaning brush to clean the pad-contact areas.
• Install the new abutment clips by hand, then use the large flat-blade screwdriver only if gentle seating pressure is needed.
• Apply a very thin layer of high-temperature silicone brake lubricant where the pad ears contact the clips. Keep lubricant away from the pad material and rotor.
• Pull each guide pin out by hand, wipe it with shop towels, apply silicone brake lubricant, and reinstall it. Make sure the rubber boots seat correctly.

Step 12: Reinstall the Caliper Bracket

• Apply a small drop of medium-strength threadlocker to the clean caliper-bracket bolt threads.
• Install both bolts by hand, then tighten them with the 18mm socket and 3/8-inch torque wrench.
• Torque to 100 Nm (74 ft-lbs).

Step 13: Install the New Brake Pads

• Install the new inner and outer pads into the bracket by hand, matching the wear-indicator position from the original pads.
• Slide each pad by hand to verify that it moves freely in the abutment clips.
• Do not put lubricant on the pad friction material or rotor surface.

Step 14: Reinstall the Caliper

• Remove the caliper from the hanger hook and place it over the new pads without twisting the hose.
• Install both guide-pin bolts by hand.
• Use the 13mm socket and 3/8-inch torque wrench to tighten the guide-pin bolts. Hold a turning guide pin with the 15mm open-end wrench.
• Torque to 44 Nm (32 ft-lbs).

Step 15: Repeat on the Opposite Side

• Use the same listed tools and repeat Steps 4 through 14 on the other rear wheel.
• Both rear rotors and all rear pads must be replaced together.

Step 16: Reinstall the Wheels

• Install each wheel and start all wheel nuts by hand.
• Use the 22mm deep socket and 1/2-inch torque wrench to snug the nuts in a star pattern.
• Use the 3-ton floor jack to raise your Grand Cherokee slightly, remove the jack stands, and lower it to the ground.
• Use the 22mm deep socket and 1/2-inch torque wrench to tighten the wheel nuts in a star pattern. Torque to 176 Nm (130 ft-lbs).

✅ After Repair

• ✅ Before moving your Grand Cherokee, press the brake pedal slowly several times until it feels firm. This seats the caliper pistons against the new pads.
• Check the brake-fluid reservoir and use DOT 3 brake fluid only if the level is below the proper mark.
• Apply and release the parking-brake pedal several times. Confirm that both rear wheels release fully.
• Start the engine and verify that the red brake warning lamp turns off after the parking brake is released.
• Perform a slow test drive in a safe area. Confirm that the pedal remains firm and that there is no pulling, scraping, or fluid leakage.
• Bed in the pads with 8-10 moderate stops from approximately 50 km/h to 15 km/h. Avoid coming to a complete stop during the sequence, then drive for 10 minutes to cool the brakes.
• Avoid hard braking and prolonged pedal holding for the first 300 km unless needed for safety.
• Recheck the wheel-nut torque after approximately 80-100 km.
