Tools You'll Need:
* Jack and jack stands: Absolutely crucial for safety. Never work under a car supported only by a jack.
* Wheel chocks: To prevent the car from rolling.
* Lug wrench: To remove the wheels.
* Wheel socket: The correct size for your lug nuts.
* C-clamp or caliper compression tool: To compress the caliper piston.
* Rotor removal tool (optional but highly recommended): These tools help prevent damaging the rotor during removal.
* Wrench(es) for caliper mounting bolts: Usually 14mm or 15mm, but check your repair manual.
* Socket and wrench for caliper bracket bolts (if applicable): Some models require removal of the entire bracket.
* Brake cleaner: To clean the mating surfaces.
* New rotors: Make sure you get the correct size and type for your Concorde.
* Torque wrench: Essential for tightening bolts to the correct specification.
* Gloves and safety glasses: Protect yourself from dirt, grease, and sharp edges.
* Penetrating oil (optional): To help loosen stubborn bolts.
Procedure:
1. Safety First: Park the car on a level surface, engage the parking brake, and chock the rear wheels. Raise the front of the car using the jack and securely support it with jack stands.
2. Remove the Wheel: Remove the lug nuts and carefully take off the wheel.
3. Compress the Caliper Piston: Using the C-clamp or caliper compression tool, slowly compress the caliper piston. This will give you enough room to remove the rotor. You may need to turn the piston as you compress it. Be careful not to damage the piston seal or brake lines.
4. Remove the Caliper: Depending on your model, you may need to remove the caliper completely or just unbolt it and swing it out of the way. If removing it, securely hang it using a piece of wire to avoid stretching the brake line.
5. Remove the Rotor: Some rotors may simply slide off. Others might require a rotor removal tool to prevent damage. If it’s stuck, gently tap it with a rubber mallet. Avoid damaging the wheel studs.
6. Clean the Hub: Thoroughly clean the wheel hub mating surface with brake cleaner. Remove any rust or debris.
7. Install the New Rotor: Carefully slide the new rotor onto the wheel studs. Ensure it’s seated properly.
8. Reinstall the Caliper: Reinstall the caliper and tighten the bolts to the manufacturer's specified torque.
9. Reinstall the Wheel: Put the wheel back on and tighten the lug nuts finger-tight. Then, using a lug wrench, tighten them in a star pattern (opposite nuts, then the others). Finally, torque the lug nuts to the manufacturer’s specification using a torque wrench.
10. Lower the Vehicle: Carefully lower the vehicle using the jack.
11. Final Checks: Double-check that all lug nuts are properly tightened. Pump the brake pedal several times to ensure the brakes are working correctly. Take the car for a short test drive to ensure everything is functioning properly.
Important Considerations:
* Brake Fluid: If you’re replacing brake pads at the same time, you may need to bleed the brakes afterward to remove air from the system.
* Caliper Bracket: Some models require the removal of the caliper bracket, making the job slightly more complex. Consult your repair manual.
* Rust: If you encounter significant rust, penetrating oil may be helpful in loosening bolts.
* Professional Help: If you're not comfortable performing this repair, it’s best to take your car to a qualified mechanic. Improperly installed brakes are extremely dangerous.
This is a general guide, and variations exist. Always refer to a repair manual specific to your 1999 Chrysler Concorde model for precise instructions and torque specifications. Safety should be your top priority when working on your vehicle's brakes.
