⚠️ Safety & Precautions

• Work on level ground and chock the rear wheels before lifting the front.
• Use jack stands; never rely on a floor jack alone.
• Let the brakes cool if the truck was recently driven. Rotors and calipers can be very hot.
• Do not press the brake pedal with the caliper removed.
• If your truck has a brake pad wear sensor on the front axle, disconnect it carefully before removing the pads.
• No battery disconnect is required for this repair.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and remove the wheel

• Use the 21mm lug 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 wheel.

Step 2: Remove the caliper

• Use the 18mm socket to remove the caliper guide pin bolts.
• Lift the caliper off the rotor and hang it with a bungee cord. Do not let it dangle by the brake hose.
• Tip: Hang the caliper right away.

Step 3: Remove the old pads and hardware

• Slide the old pads out of the bracket.
• If equipped, unplug the pad wear sensor carefully.
• Remove the pad clips and hardware from the bracket.
• Use the flat-blade screwdriver if the hardware is stuck.

Step 4: Inspect and clean the bracket

• Use brake cleaner and a wire brush to clean the pad contact points.
• Make sure the slide pins move freely. If they are dry or sticky, clean and regrease them with brake grease.
• Inspect the rotor surface. Replace the rotor if it is deeply grooved, cracked, or below spec.

Step 5: Compress the caliper piston

• Use a C-clamp or brake caliper compression tool (specialty) to slowly push the piston back into the caliper.
• Watch the brake fluid level in the master cylinder so it does not overflow.
• Tip: Compress slowly and evenly.

Step 6: Install the new pads

• Install the new hardware clips in the bracket.
• Apply a thin coat of brake grease to the pad ears and contact points only. Do not get grease on the rotor or pad friction material.
• Slide the new pads into place.
• Reconnect the pad wear sensor if equipped.

Step 7: Reinstall the caliper

• Set the caliper back over the new pads.
• Install the guide pin bolts with the 18mm socket.
• Torque to 50 Nm (37 ft-lbs).

Step 8: Reinstall the wheel

• Put the wheel back on and start all lug nuts by hand.
• Lower the truck and use the 21mm lug socket and torque wrench to tighten the lug nuts in a star pattern.
• Torque to 190 Nm (140 ft-lbs).

Step 9: Repeat on the other side

• Replace the pads on both front wheels.
• Do not replace only one side.

✅ After Repair

• Press the brake pedal several times before moving the truck. The pedal should become firm.
• Check the brake fluid level and top off if needed.
• Test the brakes at low speed first.
• Listen for unusual noises and recheck lug nut torque after a short drive.
• For best pad life, perform a few moderate stops to bed in the new pads.
