⚠️ Safety & Precautions

• ⚠️ Work on a flat, solid surface and support the vehicle with jack stands. Never rely on a jack alone.
• ⚠️ Brake dust can be harmful. Wear safety glasses and nitrile gloves, and avoid blowing dust with compressed air.
• ⚠️ Front brakes are critical safety parts. If a caliper bolt, hose, or bleeder is damaged, stop and repair it before driving.
• ⚠️ Brake fluid can damage paint. Wipe spills immediately with water and a clean rag.
• ⚠️ No battery disconnect is required for this front brake repair.

📋 Before You Begin

• Park your Grand Cherokee on level ground, shift to Park, and apply the parking brake.
• Place wheel chocks behind the rear wheels.
• Open the hood and check the brake fluid reservoir. If it is very full, remove a small amount with a clean suction tool before compressing the caliper pistons.
• A brake caliper piston compressor is a tool that pushes the caliper pistons back in so the thicker new pads will fit.
• A torque wrench is a tool that tightens bolts to the correct tightness so they are not loose or over-tightened.
• Do one side at a time so the other side can be used as a reference.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Wheel Lug Nuts

• Use a 22mm lug nut socket and 1/2-inch drive breaker bar to loosen each front wheel lug nut about half a turn.
• Do not remove the lug nuts yet.
• Loosen wheels before lifting.

Step 2: Lift and Support the Front of the Vehicle

• Use a floor jack to lift the front of your Grand Cherokee at the front center crossmember or approved front lift point.
• Place jack stands under the approved front frame/suspension support points.
• Lower the vehicle gently onto the jack stands and lightly shake the vehicle to confirm it is stable.

Step 3: Remove the Front Wheels

• Use the 22mm lug nut socket to remove the loosened lug nuts.
• Remove both front wheels and set them flat on the ground.

Step 4: Inspect the Brake Assembly

• Use safety glasses and nitrile gloves before touching the brake parts.
• Look at the brake hose, caliper, and rotor before disassembly.
• If the hose is cracked, leaking, or twisted, it must be repaired before driving.

Step 5: Remove the Caliper Slide Pin Bolts

• Use a 13mm socket and 3/8-inch drive ratchet to remove the two caliper slide pin bolts from the back of the caliper.
• A slide pin lets the brake caliper move slightly so both pads clamp evenly.
• If a slide pin spins, hold the pin with an appropriate wrench while removing the bolt with the 13mm socket.

Step 6: Remove and Support the Caliper

• Use a flat-blade screwdriver or small pry bar to gently work the caliper off the rotor.
• Hang the caliper from the suspension using a bungee cord.
• Do not let the caliper hang by the rubber brake hose.

Step 7: Remove the Old Brake Pads

• Pull the old brake pads out of the caliper bracket by hand.
• Use a flat-blade screwdriver if a pad is stuck in the bracket.
• Note which pad had the wear indicator so the new pads can be matched correctly.

Step 8: Remove the Caliper Bracket

• Use a 21mm socket and 1/2-inch drive breaker bar to remove the two caliper bracket bolts.
• Remove the caliper bracket and set it on a clean surface.
• These bolts are usually tight, so keep the socket straight on the bolt head.

Step 9: Remove the Old Rotor

• Pull the rotor straight off the hub by hand.
• If it is rust-stuck, use a dead blow hammer to tap around the rotor hat area until it loosens.
• Do not hit the wheel studs.
• Rust makes rotors stick.

Step 10: Clean the Hub Face

• Use a wire brush to clean rust and dirt from the wheel hub face.
• Use brake parts cleaner and shop towels to wipe the hub clean.
• The rotor must sit flat against the hub to prevent brake vibration.

Step 11: Prepare and Install the New Rotor

• Spray both sides of the new rotor friction surface with brake parts cleaner.
• Wipe it dry with shop towels.
• Slide the new rotor onto the hub.
• Thread one lug nut on by hand to hold the rotor in place while you work.

Step 12: Clean and Prepare the Caliper Bracket

• Use a flat-blade screwdriver to remove the old brake hardware clips from the caliper bracket.
• Use a wire brush to clean the bracket where the clips sit.
• Install the new clips from the front brake hardware kit by pressing them into place by hand.
• Apply a thin layer of brake lubricant to the pad contact points on the clips.
• Do not put lubricant on the rotor or pad friction material.

Step 13: Reinstall the Caliper Bracket

• Position the caliper bracket over the rotor.
• Start both bracket bolts by hand to avoid cross-threading.
• Use a 21mm socket and 1/2-inch drive torque wrench to tighten the caliper bracket bolts.
• Torque to 176 Nm (130 ft-lbs).

Step 14: Compress the Caliper Pistons

• Place the old inner brake pad against the caliper pistons.
• Use the brake caliper piston compressor to slowly push the pistons fully back into the caliper.
• Watch the brake fluid reservoir under the hood while compressing the pistons. Do not let it overflow.
• If needed, use an 11mm wrench and brake bleeder bottle to open the bleeder slightly while compressing, then close it before releasing the compressor.

Step 15: Install the New Brake Pads

• Slide the new brake pads into the caliper bracket by hand.
• Make sure the friction material faces the rotor.
• The pads should move smoothly in the new hardware clips.
• If they bind, remove them and clean the bracket contact areas again with the wire brush.

Step 16: Reinstall the Caliper

• Remove the bungee cord and place the caliper over the new pads and rotor.
• Start both caliper slide pin bolts by hand.
• Use a 13mm socket and 3/8-inch drive torque wrench to tighten the slide pin bolts.
• Torque to 32 Nm (24 ft-lbs).

Step 17: Repeat on the Other Front Side

• Use the same tools and steps on the other front brake assembly.
• Replace pads and rotors in pairs, so both front brakes match.

Step 18: Reinstall the Front Wheels

• Remove the temporary lug nut holding each rotor.
• Install each wheel and start all lug nuts by hand.
• Use the 22mm lug nut socket to snug the lug nuts in a star pattern.

Step 19: Lower the Vehicle and Torque the Lug Nuts

• Use the floor jack to raise the vehicle slightly and remove the jack stands.
• Lower the vehicle until the tires touch the ground.
• Use the 22mm lug nut socket and 1/2-inch drive torque wrench to tighten the lug nuts in a star pattern.
• Torque to 176 Nm (130 ft-lbs).

Step 20: Pump the Brake Pedal

• Before starting or driving, press the brake pedal several times until it feels firm.
• This moves the caliper pistons back into position against the new pads.
• If the pedal stays soft or sinks, do not drive until the brake system is inspected and bled.

✅ After Repair

• ✅ Check the brake fluid level and top off with DOT 3 brake fluid if needed.
• ✅ Start the engine and press the brake pedal again. It should feel firm and steady.
• ✅ Test drive slowly in a safe area first. Confirm the vehicle stops straight and quietly.
• ✅ Bed in the new pads and rotors: make 8-10 moderate stops from about 30-40 mph, allowing time between stops for cooling.
• ✅ Avoid hard panic stops for the first 200 miles unless needed for safety.
• ✅ Recheck lug nut torque after the first short drive: 176 Nm (130 ft-lbs).
