📋 Before You Begin

• Keep the brake fluid cap loose while pushing pistons back.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and remove the wheel

• Use the 21mm socket and breaker bar to loosen the lug nuts before lifting.
• Raise the front corner with the floor jack and support it with jack stands.
• Remove the lug nuts and take off the wheel.
• Set the wheel flat under the truck as a backup.

Step 2: Remove the caliper

• Use the 14mm socket and ratchet to remove the two caliper slide pin bolts.
• Lift the caliper off the rotor carefully.
• Hang the caliper with a bungee cord or mechanic’s wire; do not let it dangle by the brake hose.

Step 3: Remove the old pads and hardware

• Pull the old inner and outer brake pads out of the bracket.
• Remove the pad clips and hardware if they are included in your kit.
• Use the flat-blade screwdriver if the pads are stuck, but do not damage the rotor or bracket.

Step 4: Inspect and clean the bracket

• Use the wire brush and brake cleaner to clean the pad contact areas on the bracket.
• Check the rotor for deep grooves, cracks, or heavy rust.
• If the slide pins move stiffly, remove and clean them before reassembly.
• Smooth pin movement helps prevent uneven wear.

Step 5: Compress the caliper piston

• Use the C-clamp or disc brake piston tool to slowly push the piston back into the caliper.
• Go slow and watch the brake fluid reservoir so it does not overflow.
• If the piston resists, stop and make sure the bleed screw is closed and the tool is seated correctly.

Step 6: Install the new pads and hardware

• Install the new hardware clips in the bracket if your parts kit includes them.
• Apply a thin layer of brake grease to the pad ears and contact points only.
• Install the new inner and outer pads in the same positions as the old ones.
• Make sure the friction material faces the rotor.

Step 7: Reinstall the caliper

• Slide the caliper over the new pads and rotor.
• Use the 14mm socket and ratchet to reinstall the caliper bolts.
• Torque to 35 Nm (26 ft-lbs).

Step 8: Reinstall the wheel

• Put the wheel back on and hand-start the lug nuts.
• Lower the truck and use the 21mm socket and torque wrench to tighten the lug nuts in a star pattern.
• Torque to 131 Nm (97 ft-lbs).

Step 9: Repeat on the other side

• Perform the same steps on the opposite front wheel.
• Replace pads in pairs so braking stays balanced.

✅ After Repair

• Before driving, pump the brake pedal slowly until it feels firm.
• Check the brake fluid level and top off if needed.
• Make sure the lug nuts are still torqued correctly after a short test drive.
• Test the brakes at low speed first.
• For the first 200 miles, avoid hard stops unless needed for safety.
• New pads need a short break-in period.
