Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety glasses and gloves for protection.

2. Remove the Wheel

Use a lug wrench to loosen the wheel lug nuts, but do not remove them completely.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Visually check the brake pads for wear. Replace if the friction material is less than 3 mm.
Inspect the brake rotors for any signs of damage or excessive wear. Replace if there are deep grooves or if they are below the minimum thickness specification.
Check the caliper for proper movement and any signs of fluid leaks or corrosion.

4. Replace Brake Pads and Rotors (if necessary)

Brake Pads:
1. Remove the caliper bolts using a socket wrench and carefully slide the caliper off the rotor.
2. Remove the old brake pads from the caliper bracket.
3. Install the new brake pads, ensuring proper orientation.
4. Compress the caliper piston using a brake caliper tool or C-clamp to allow for new pad thickness.
Brake Rotors:
1. Remove the caliper bracket by unscrewing the bolts.
2. Remove the old rotor by sliding it off the hub. If it’s stuck, gently tap it with a rubber mallet.
3. Clean the hub surface with brake cleaner.
4. Install the new rotor, ensuring it is seated correctly.

5. Reassemble the Brake Assembly

Reattach the caliper bracket and torque the bolts to the manufacturer’s specifications (usually around 79 ft-lbs).
Reinstall the caliper over the new pads and secure it with the caliper bolts, torquing to specifications (typically around 25 ft-lbs).

6. Reinstall Wheel and Lower Vehicle

Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands using the jack.
Once on the ground, torque the lug nuts to the manufacturer’s specifications (usually around 76 ft-lbs).

7. Final Checks

Pump the brake pedal several times to ensure proper pressure is restored.
Check the brake fluid level and top off if necessary.
