Here's a general overview. Specifics may vary slightly depending on your Avenger's trim level and options. Always consult a repair manual specific to your year and model for detailed instructions and torque specifications. A Haynes or Chilton manual is a good investment.
Tools You'll Need:
* Jack and jack stands: Essential for safety. Never work under a car supported only by a jack.
* Lug wrench: To remove the wheels.
* Wheel chocks: To prevent the car from rolling.
* Socket wrench set and ratchets: Various sizes, including metric.
* Wrench set: For caliper bolts and brake line fittings (if replacing lines).
* C-clamp or brake caliper compression tool: To compress the caliper piston.
* Brake cleaner: To clean parts thoroughly.
* New brake pads and rotors (if needed): Ensure you get the correct parts for your Avenger.
* Gloves: To keep your hands clean.
* Safety glasses: To protect your eyes.
* Torque wrench: Crucial for tightening bolts to the correct specification, preventing damage and ensuring safety.
* Penetrating lubricant (like PB Blaster): To help loosen rusted or stuck bolts.
Steps (Front Brakes - Rear brakes are similar but simpler):
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks on the wheels opposite the ones you're working on.
2. Jack Up and Secure: Safely jack up the vehicle and securely place it on jack stands.
3. Remove Wheel: Remove the lug nuts and then the wheel.
4. Remove Caliper:
* Locate the caliper bolts holding the caliper to the caliper bracket.
* Apply penetrating lubricant if necessary and carefully remove the bolts.
* Gently support the caliper with one hand as you remove the bolts to avoid stressing the brake line.
5. Compress Caliper Piston: Using the C-clamp or compression tool, carefully compress the caliper piston. This creates space for the new, thicker brake pads. Be careful not to damage the piston seal.
6. Remove Old Brake Pads: The old brake pads should now slide out.
7. Inspect Rotor: Inspect the rotor for wear, scoring, or excessive rust. If it's worn or damaged, it needs to be replaced.
8. Install New Pads: Carefully install the new brake pads into the caliper.
9. Reinstall Caliper: Reinstall the caliper onto the bracket, making sure the caliper slides freely. Tighten the bolts to the manufacturer's specified torque.
10. Reinstall Wheel: Reinstall the wheel and tighten the lug nuts to the manufacturer's specified torque (in a star pattern).
11. Repeat on Other Side: Repeat steps 4-10 for the other front wheel.
12. Lower Vehicle: Carefully lower the vehicle from the jack stands.
13. Pump Brakes: Pump the brake pedal several times to build up pressure.
14. Test Drive: Take a short test drive to ensure the brakes are working correctly. If you feel any unusual vibrations, noises, or spongy feeling, there is something not right.
Rear Brakes: The rear brakes are typically simpler, often using drum brakes or simpler disc brakes. The process will be similar, but you might be dealing with different components. Again, consult your repair manual.
Important Considerations:
* Bleeding Brakes: If you replace any brake lines or significantly disturb the brake system, you'll likely need to bleed the brakes to remove air bubbles from the lines. This requires two people and a bleeding kit.
* Rotor Resurfacing: Slightly worn rotors can sometimes be resurfaced on a lathe to remove uneven wear. However, if the rotor is excessively worn or damaged, replacement is necessary.
* Brake Fluid: Check and top off your brake fluid level after the job. Brake fluid is corrosive, so clean any spills immediately.
This is a simplified overview. Always consult a repair manual specific to your 1999 Dodge Avenger before attempting this repair. Improper brake installation can lead to serious injury or death. If you are unsure about any step, it's best to seek professional help from a qualified mechanic.
