🔧 Grand Cherokee - Rear Brake Pads & Rotor Replacement

You’ll be removing the rear wheels, swapping the rear brake pads, and replacing the rear rotors. On your Grand Cherokee, the parking brake uses small “drum-in-hat” shoes inside the rear rotor, so rotor removal sometimes needs a quick parking-brake adjuster step.

Difficulty Level: Intermediate | Estimated Time: 2.0-3.5 hours

⚠️ Safety & Precautions

• 🛑 Work on level ground and chock the front wheels before lifting the rear.
• 🧯 Brake dust is harmful—use brake cleaner, not compressed air.
• 🔥 Brakes can be hot—let everything cool before touching parts.
• 🧱 Support the SUV with jack stands; never rely on a floor jack alone.
• 🧪 Do not let the caliper hang by the brake hose—support it with a hanger.
• 🔓 Keep the parking brake fully released before removing rear rotors.

📋 Before You Begin

• 🧭 Park on level ground, shift to P, and fully release the parking brake.
• 🧱 Chock both front wheels using wheel chocks.
• 🛞 Crack the rear lug nuts loose 1/2 turn with a 21mm socket and breaker bar before lifting.
• 🧪 Open the brake fluid reservoir cap (under the hood) and set it loosely on top. This helps the rear caliper piston compress easier. Do not overfill afterward.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the rear

• Use a floor jack (rated 3-ton minimum) to lift the rear at a proper lift point, then set the vehicle onto jack stands (rated 3-ton minimum, pair).
• Remove the rear wheels using a 21mm socket and ratchet.

Step 2: Remove the rear caliper (pads still inside)

• Turn the steering wheel is not needed for rear work—just position yourself for access.
• Locate the two rear caliper slide/guide bolts on the back of the caliper.
• Remove the slide/guide bolts using a ratchet (3/8" drive) with the correct metric socket (commonly 13mm) and hold the slide pin with a metric wrench if it spins.
• Lift the caliper off the bracket, then hang it from the suspension using a bungee cord or mechanics wire.

Step 3: Remove old pads and hardware

• Pull the old brake pads out of the bracket by hand. Use a flathead screwdriver (medium) gently if they’re stuck.
• Remove the old pad hardware clips from the bracket using a flathead screwdriver (medium).

Step 4: Remove the caliper bracket

• Remove the two caliper bracket bolts using a breaker bar (1/2" drive) and the correct metric socket (commonly 18mm or 21mm depending on build).
• Set the bracket aside on a towel.

Step 5: Remove the rear rotor (parking brake “drum-in-hat” inside)

• If the rotor slides off, remove it by hand.
• If the rotor is stuck to the hub, spray the hub center with brake cleaner spray, then tap the rotor hat with a rubber mallet to break rust loose.
• If the rotor won’t come off because the parking brake shoes are holding it, back off the adjuster:
  • Use a flathead screwdriver (medium) to pop out the small rubber access plug in the rotor hat (if equipped).
  • Rotate the rotor until the access hole lines up with the star-wheel adjuster.
  • Use the flathead screwdriver (medium) to turn the star wheel to retract (loosen) the parking brake shoes until the rotor comes off.

Step 6: Clean and prep the hub and bracket

• Use a wire brush to clean rust off the hub face (where the rotor sits).
• Spray the area with brake cleaner spray and wipe with shop towels.
• Apply a very thin film of anti-seize compound to the hub center (not on the wheel studs).

Step 7: Install the new rotor

• Clean the new rotor surfaces using brake cleaner spray and shop towels (this removes shipping oil).
• Slide the new rotor onto the hub.
• If the rotor drags hard and won’t sit flush, the parking brake shoes are still too tight—repeat Step 5 adjuster retraction using a flathead screwdriver (medium).

Step 8: Reinstall the caliper bracket

• Reinstall the bracket over the new rotor using the original bracket bolts with a ratchet to start them by hand.
• Tighten with a torque wrench: Torque to 125 Nm (92 ft-lbs).

Step 9: Install new pad hardware and pads

• Install the new hardware clips into the bracket by hand (they should snap in). Use a flathead screwdriver (medium) if needed.
• Apply a thin layer of brake caliper grease (silicone-based) on the pad ears where they touch the clips. Grease only metal-to-metal contact points.
• Slide the new pads into the bracket.

Step 10: Compress the rear caliper piston

• Place an old brake pad against the caliper piston, then use a C-clamp brake piston tool to slowly push the piston fully back into the caliper.
• A C-clamp brake piston tool is a screw clamp that presses the piston straight in.
• Watch the brake fluid reservoir while compressing—if it starts to overflow, stop and remove some fluid (do not spill on paint).

Step 11: Reinstall the caliper

• Set the caliper back over the new pads.
• Reinstall the slide/guide bolts using a ratchet (3/8" drive) and correct metric socket.
• Tighten with a torque wrench: Torque to 35 Nm (26 ft-lbs).

Step 12: Reinstall wheels and torque lug nuts

• Reinstall the wheels and hand-thread the lug nuts.
• Lower the SUV off the jack stands using the floor jack.
• Torque the lug nuts in a star pattern using a torque wrench: Torque to 135 Nm (100 ft-lbs).

Step 13: Set the parking brake (only if rotor was tight)

• If you loosened the parking brake adjuster in Step 5, you may need to re-adjust it so it holds properly.
• With the rotor installed, use a flathead screwdriver (medium) through the access hole to tighten the star wheel until you feel light drag, then back off slightly so the rotor turns freely with minimal contact.

✅ After Repair

• 🦶 Pump the brake pedal 10–15 times before driving until it feels firm (this seats the pistons against the new pads).
• 🧪 Check brake fluid level and top off if needed (do not overfill).
• 🛞 Test at low speed first: confirm normal stopping and no pulling/noise.
• 🔥 Bed-in (break-in) the pads: do 6–8 medium stops from ~40 km/h to 10 km/h, letting brakes cool 30–60 seconds between stops. Avoid hard stops at first.
• 🔍 Recheck lug nut torque after 50–100 km using a torque wrench.
