Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Use wheel chocks for added safety.

2. Remove Wheel Assembly

Tools Required: Socket set, jack stands
Raise the vehicle using a jack and secure it on jack stands.
Remove the lug nuts with a socket and take off the wheel.

3. Inspect and Remove Brake Components

Inspect the brake pads and rotors for damage.
If pads are worn down to the backing or rotors are scored, proceed with replacement.
Remove the caliper bolts using a socket.
Carefully slide the caliper off the rotor and support it with a bungee cord or rope to avoid straining the brake line.
Remove the brake pads from the caliper bracket.

4. Replace Brake Pads and Rotors (if necessary)

If the rotors are damaged, remove retaining screws (if applicable) and slide off the old rotor.
Install new rotors by aligning them with the hub and securing them with screws.
Insert new brake pads into the caliper bracket, ensuring they are seated properly.

5. Reinstall Caliper

Tools Required: Torque wrench
Position the caliper over the new pads and rotor.
Reinstall caliper bolts and tighten to manufacturer’s torque specifications (usually around 25-35 ft-lbs).
Ensure the caliper is properly aligned and moves freely.

6. Reassemble and Test

Reinstall the wheel and lug nuts, tightening them in a crisscross pattern to the manufacturer’s specifications (typically 80-100 ft-lbs).
Lower the vehicle off the jack stands and remove wheel chocks.
Pump the brake pedal to ensure proper caliper contact with the pads.
