⚠️ Safety & Precautions

• ⚠️ Work on a flat, solid surface only. Never rely on a jack by itself.
• ⚠️ Support your Wrangler with jack stands before removing wheels.
• ⚠️ Wear safety glasses and gloves. Brake dust can irritate skin and eyes.
• ⚠️ Do not press the brake pedal while the caliper is removed.
• ⚠️ Keep grease and brake cleaner off the pad friction surface and rotor face.
• ⚠️ Battery disconnect is not required for this front brake job.

📋 Before You Begin

• 🅿️ Park your Wrangler on level ground and leave the transmission in 1st gear.
• 🛞 Set the parking brake and place wheel chocks behind the rear tires.
• 🧼 Open the hood and check the brake fluid reservoir level. If it is full, remove a small amount with a clean turkey baster before compressing the caliper pistons.
• 📌 A caliper is the clamp that squeezes the brake pads against the rotor.
• 📌 A rotor is the round metal disc behind the wheel that the pads squeeze to stop the vehicle.
• 📌 A torque wrench tightens bolts to the correct tightness so they are not loose or over-tightened.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Lug Nuts

• Use the 19mm lug nut socket and 1/2-inch drive breaker bar to loosen the front wheel lug nuts about 1/2 turn.
• Do this while the tires are still touching the ground.
• Tip: Do not remove them yet.

Step 2: Lift and Support the Front

• Use the floor jack under the front axle tube to lift one side, or lift from the center of the front axle if stable.
• Place jack stands under the front axle tubes on both sides.
• Lower your Wrangler gently onto the jack stands.
• Use your hands to lightly shake the vehicle. It should feel stable before you continue.

Step 3: Remove the Front Wheels

• Use the 19mm lug nut socket and 1/2-inch drive ratchet to remove the lug nuts.
• Remove both front wheels and set them flat under the frame area as an extra safety backup.

Step 4: Inspect the Brake Assembly

• Use a flashlight if needed and look at the caliper, pads, rotor, and brake hose.
• Check for brake fluid leaks, torn rubber hoses, or uneven pad wear.
• If one pad is much thinner than the other, the caliper slide pins may be sticking.

Step 5: Remove the Caliper Slide Bolts

• Use the 13mm socket and 3/8-inch drive ratchet to remove the two caliper slide bolts on the back side of the caliper.
• A slide bolt holds the moving part of the caliper to the bracket.
• Hold the caliper steady with your other hand as the last bolt comes out.

Step 6: Remove and Support the Caliper

• Use the flat blade screwdriver to gently pry the caliper away from the rotor if it feels stuck.
• Lift the caliper off the rotor.
• Use the bungee cord to hang the caliper from the coil spring or frame.
• Do not let the caliper hang by the rubber brake hose.

Step 7: Remove the Old Brake Pads

• Use your hands or the flat blade screwdriver to remove the old inner and outer brake pads from the caliper bracket.
• Notice how the pads and metal clips are positioned before removing them.
• Tip: Take a photo before disassembly.

Step 8: Remove the Caliper Bracket

• Use the 21mm socket, 6-inch socket extension, and 1/2-inch drive breaker bar to remove the two caliper bracket bolts.
• The caliper bracket is the heavy metal mount that holds the pads in place.
• Remove the bracket and set it on your work surface.

Step 9: Remove the Old Rotor

• Slide the rotor straight off the wheel studs by hand.
• If the rotor is stuck, use the rubber mallet to tap around the rotor hat until it loosens.
• The rotor hat is the raised center section of the rotor.
• Do not strike the wheel studs.

Step 10: Clean the Hub Surface

• Use the wire brush to clean rust from the wheel hub face where the rotor sits.
• Use brake cleaner spray and shop towels to wipe the surface clean.
• This helps the new rotor sit flat and prevents brake pedal vibration.

Step 11: Prepare the New Rotor

• Use brake cleaner spray and shop towels to clean both sides of the new rotor.
• New rotors often have an oily coating to prevent rust during shipping.
• Slide the new rotor onto the wheel studs by hand.
• Thread one lug nut on backward by hand to hold the rotor in place.

Step 12: Clean and Prepare the Caliper Bracket

• Use the flat blade screwdriver to remove the old brake hardware clips from the bracket.
• Use the wire brush and brake parts cleaning brush to clean the pad contact areas.
• Install the new hardware clips from the front brake hardware kit by hand.
• Apply a thin layer of brake caliper slide pin grease only where the pad ears touch the clips.
• Pad ears are the small tabs on each end of the brake pad backing plate.

Step 13: Reinstall the Caliper Bracket

• Position the caliper bracket over the new rotor.
• Start both caliper bracket bolts by hand to avoid cross-threading.
• Use the 21mm socket, 6-inch socket extension, and 1/2-inch drive torque wrench to tighten the bracket bolts.
• Torque to 169 Nm (125 ft-lbs)

Step 14: Compress the Caliper Piston

• Place one old brake pad against the caliper piston.
• Use the brake caliper piston compressor tool to slowly push the piston fully back into the caliper.
• The piston is the round part inside the caliper that pushes the brake pad.
• Watch the brake fluid reservoir while compressing. Remove excess fluid if it approaches the top.
• Tip: Compress slowly to protect seals.

Step 15: Install the New Brake Pads

• Use your hands to install the new inner and outer brake pads into the caliper bracket.
• Make sure the pad friction material faces the rotor.
• The friction material is the rough surface that contacts the rotor.
• The pads should slide smoothly in the new clips. If they bind, remove them and clean the bracket 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 bolts by hand.
• Use the 13mm socket and 3/8-inch drive torque wrench to tighten the slide bolts.
• Torque to 35 Nm (26 ft-lbs)

Step 17: Repeat on the Other Side

• Repeat Steps 5 through 16 on the other front brake assembly.
• Always replace front brake pads and rotors in pairs.

Step 18: Reinstall the Front Wheels

• Remove the temporary lug nut holding each rotor.
• Install each wheel by hand.
• Use the 19mm lug nut socket and 1/2-inch drive ratchet to snug the lug nuts in a star pattern.
• A star pattern means tightening across the wheel instead of going around in a circle.

Step 19: Lower the Vehicle

• Use the floor jack to lift the front axle slightly off the jack stands.
• Remove the jack stands.
• Lower your Wrangler carefully to the ground.

Step 20: Torque the Lug Nuts

• Use the 19mm lug nut socket and 1/2-inch drive torque wrench to tighten the lug nuts in a star pattern.
• Torque to 129 Nm (95 ft-lbs)
• Recheck the torque after a short drive.

✅ After Repair

• 🛑 Before starting or driving, press the brake pedal slowly several times until it feels firm.
• 🧪 Check the brake fluid reservoir and top off with DOT 3 brake fluid if needed.
• 🔍 Look behind both front wheels for brake fluid leaks.
• 🚗 Test drive at low speed in a safe area before normal driving.
• 🔥 Bed in the new pads and rotors with 8-10 moderate stops from about 30 mph to 5 mph, allowing a short cooling period between stops.
• ⚠️ Avoid hard braking for the first 200 miles unless needed for safety.
