Here's a general outline of the process. This is not a complete, step-by-step guide, and specific procedures may vary slightly depending on your Avenger's exact model and trim. Always consult a repair manual specific to your year and model for detailed instructions and torque specifications.
Tools you'll likely need:
* Jack and jack stands (Crucial for safety)
* Lug wrench
* Wheel chocks
* Socket wrench set (metric)
* Torque wrench
* Caliper piston compression tool (C-clamp can sometimes work, but a proper tool is recommended)
* Wire brush or brake cleaner
* Rotor removal tool (sometimes needed, depending on the rotor's fit)
* New brake rotors and pads (replace pads at the same time for best results)
* Gloves
* Safety glasses
General Steps:
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels. 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 carefully take off the wheel.
3. Remove the Caliper: You'll need to remove the brake caliper assembly. This usually involves removing a bolt or two securing it to the caliper bracket. Once removed, carefully support the caliper using a bungee cord or wire to prevent it from hanging by the brake line.
4. Compress the Caliper Piston: Use the caliper piston compression tool to push the piston back into the caliper housing. This creates space for the new, thicker rotor. Be careful not to damage the piston seal.
5. Remove the Old Rotor: Sometimes the rotor slides right off; other times it might be stuck. A rotor removal tool can help if it's seized. If it's particularly stubborn, try using a hammer and punch (carefully!) to tap it loose. Be careful not to damage the wheel hub.
6. Clean the Hub: Clean the wheel hub thoroughly using a wire brush and brake cleaner to remove any rust or debris.
7. Install the New Rotor: Carefully slide the new rotor onto the wheel studs. Make sure it's seated properly.
8. Reinstall the Caliper: Reinstall the caliper assembly, ensuring it's properly seated and the bolts are tightened to the manufacturer's specifications (use a torque wrench).
9. Reinstall the Wheel: Put the wheel back on and tighten the lug nuts to the manufacturer's specifications (use a torque wrench).
10. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
11. Check for proper function: Before driving, pump the brake pedal several times to ensure the brakes are working properly. Then take it for a short test drive and check for any unusual noises or vibrations.
Important Considerations:
* Brake Pad Replacement: It's highly recommended to replace your brake pads at the same time as the rotors. Replacing worn pads with new rotors only leads to uneven wear.
* Torque Specifications: Use a torque wrench and consult your repair manual for the correct torque specifications for all bolts. Over-tightening can damage components, while under-tightening can lead to looseness and failure.
* Brake Fluid: If you're doing a complete brake job including bleeding the brakes, you might need to bleed the brakes afterward. This should only be done if you know how.
Again, if you're not comfortable with this process, take your car to a professional mechanic. Brakes are a critical safety component, and a mistake could have serious consequences.
