Step-by-Step Instructions
1. Safety First: Park your truck on a level surface and engage the parking brake.
2. Locate the Brake Pad Sensor: Remove the front wheels and locate the brake pad sensor on the inside of the brake caliper. It is usually a small, black or green wire with a connector.
3. Disconnect the Sensor: Use a Phillips head screwdriver to loosen the screw holding the sensor in place. Then, gently pull the sensor out of its connector.
4. Replace the Brake Pads: Remove the old brake pads and install the new ones. Ensure they are properly seated in the caliper and that the anti-rattle clips are in place.
5. Apply Brake Caliper Grease: Apply a thin layer of brake caliper grease to the back of the new brake pads and the contact points between the pads and the caliper.
6. Reconnect the Sensor: Insert the brake pad sensor back into its connector and tighten the screw.
7. Reset the Brake Pad Monitor: Turn the ignition key to the “On” position without starting the engine. Then, press and hold the odometer reset button on the instrument cluster for approximately 10 seconds. The “Brake Pad Monitor Reset” message will appear on the display.
8. Reinstall the Wheels: Mount the wheels back onto the truck and tighten the lug nuts.
