How do you change rear disc brakes on 1999 Ford Taurus?

Replacing rear disc brakes on a 1999 Ford Taurus is a moderately involved job requiring some mechanical aptitude and tools. This is a general overview; consult a repair manual specific to your vehicle year and model for detailed instructions and torque specifications. Improperly installed brakes can be extremely dangerous. If you're not comfortable with this, take it to a professional mechanic.

Tools You'll Need:

* Jack and jack stands (SAFETY FIRST: Always use jack stands, never rely solely on a jack)

* Wheel chocks

* Lug wrench

* Socket wrench set (metric)

* Torque wrench

* Brake caliper compression tool

* C-clamp or similar for caliper piston compression

* Wire brush or brake cleaner

* New brake pads

* New brake rotors (likely needed, as rotors usually wear with pads)

* New caliper bolts (recommended)

* Penetrating oil (like PB Blaster)

* Gloves

* Safety glasses

Steps:

1. Safety First: Park on a level surface, engage the parking brake, and chock the front wheels. Raise the rear of the vehicle using the jack and securely place it on jack stands.

2. Remove the Wheel: Remove the lug nuts and carefully take off the wheel.

3. Remove the Caliper:

* Use a wire brush to clean away any accumulated dirt and debris. Apply penetrating oil to caliper bolts if needed.

* Use the appropriate socket to remove the caliper mounting bolts. These bolts are often 13mm or 14mm.

* Carefully support the caliper with a bungee cord or wire to prevent it from hanging by the brake line. Do not let the brake line dangle or become stressed.

4. Compress the Caliper Piston: Use a caliper compression tool (best) or a C-clamp to carefully push the brake caliper piston back into the caliper bore. This creates space for the new, thicker brake pads. You may need to turn the piston as you compress it.

5. Remove the Brake Pads: Remove the old brake pads. Note their orientation, as some may have wear indicators or other identifying features.

6. Remove the Rotor (if replacing): Depending on the design, the rotor may be held on by bolts or it might just slide off after removing the caliper. Refer to your repair manual.

7. Install the New Rotor (if replacing): Clean the rotor mounting surface thoroughly. Install the new rotor, ensuring it's properly seated.

8. Install the New Brake Pads: Install the new brake pads, ensuring they slide freely in their guides.

9. Install the Caliper: Reinstall the caliper, making sure the caliper bracket is properly aligned. Tighten the caliper mounting bolts to the manufacturer's specified torque.

10. Reinstall the Wheel: Install the wheel and tighten the lug nuts in a star pattern to ensure even pressure.

11. Lower the Vehicle: Carefully lower the vehicle from the jack stands.

12. Torque Lug Nuts: Torque the lug nuts to the manufacturer's specified torque using a torque wrench.

13. Pump the Brakes: Get back in the car and pump the brake pedal several times to build up pressure and engage the new brakes.

14. Test Drive: Before driving, double-check everything is securely fastened. Take a short test drive to ensure the brakes are functioning correctly. Listen for any unusual noises.

Important Considerations:

* Brake Fluid: If you have to bleed the brakes, consult your repair manual on how to do so properly. Low brake fluid levels are a safety hazard.

* Repair Manual: A repair manual specific to your 1999 Ford Taurus is highly recommended. It will provide detailed diagrams, torque specifications, and other crucial information.

* Parts: Use high-quality replacement parts from a reputable supplier.

* Safety: If you are not comfortable performing this repair, take your vehicle to a qualified mechanic. Improperly installed brakes can lead to serious injury or death.

This is a simplified guide. Always refer to a repair manual for your specific vehicle for detailed instructions and safety precautions. Remember safety is paramount.
