However, if you are experienced and proceed with caution, here's a general overview. Always consult your Avalanche's specific repair manual for detailed instructions and torque specifications. These specs are crucial for safety.
Tools You'll Need:
* Jack and jack stands (crucial for safety!)
* Lug wrench
* Wheel chocks
* Socket wrench set (metric)
* Wrenches (metric)
* C-clamp or brake caliper compressor tool
* Brake cleaner
* New brake pads and rotors (if needed)
* Anti-seize lubricant
* Gloves
* Safety glasses
General Steps (May vary depending on your year and model):
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels opposite the one you're working on. Raise the vehicle using the jack and securely support it with jack stands. Never work under a vehicle supported only by a jack.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Inspect the Brakes: Carefully inspect the brake pads and rotors for wear. Replace both pads and rotors if the rotors are scored or excessively worn. Pay attention to the brake caliper and its components for any signs of damage.
4. Remove the Caliper: There are usually bolts holding the caliper to the bracket. Unscrew these bolts. You may need to use a C-clamp or caliper compressor tool to compress the caliper piston to create space for the new, thicker brake pads. Carefully support the caliper while working to avoid damaging the brake line.
5. Remove the Brake Pads: The old brake pads should now be easily removable. Clean the caliper bracket and piston with brake cleaner.
6. Replace the Rotors (if needed): If replacing rotors, remove the old rotors, usually by unscrewing them from the wheel hub. Clean the hub before installing the new rotors.
7. Install New Brake Pads: Install the new brake pads into the caliper bracket.
8. Reinstall the Caliper: Reinstall the caliper onto the bracket, ensuring the caliper slides smoothly.
9. Reinstall the Wheel: Put the wheel back on and tighten the lug nuts.
10. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
11. Bleed the Brakes (Very Important): After installing new components, bleeding the brakes is crucial to remove air from the brake lines. This is typically done by opening the bleeder valve on each caliper while someone pumps the brake pedal. This requires two people and a wrench. If you're unsure, consult a repair manual or have a mechanic do this.
12. Test the Brakes: Before driving, carefully test the brakes several times to make sure they work correctly.
Again, this is a simplified overview. Consult your Avalanche's repair manual for year-specific instructions and torque specifications. Improperly installed brakes can lead to brake failure, resulting in serious injury or death. If you have any doubts, take your Avalanche to a qualified mechanic.
