Solution

1. Preparation

Gather necessary tools and parts.
Safely lift the vehicle and secure it on jack stands.
Remove the wheel to access the brake components.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and support it so the brake line is not strained.
3. Remove the old brake pads from the caliper bracket.
4. Compare the thickness of the old pads to the manufacturer’s specifications. Replace if below the minimum thickness.
5. Install new brake pads in the caliper bracket, ensuring proper orientation.
Tools Required: Socket set, torque wrench
Safety Warnings: Ensure the vehicle is securely lifted and supported.

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. If the rotors are scored or below specification, remove the caliper bracket by unbolting it.
2. Slide the rotor off the hub.
3. Clean the hub surface to ensure proper seating of the new rotor.
4. Install new rotors, ensuring they are aligned correctly.
5. Reattach the caliper bracket and torque the bolts to manufacturer specifications.
Tools Required: Torque wrench, socket set, rotor puller (if needed)
Safety Warnings: Handle rotors carefully to avoid injury from sharp edges.

4. Reassemble and Test

Sub-steps:
1. Reinstall the caliper over the new pads and secure it with the caliper bolts.
2. Reinstall the wheel and torque the lug nuts to proper specifications.
3. Lower the vehicle and pump the brake pedal to seat the pads against the rotor.
Tools Required: Torque wrench
Safety Warnings: Ensure all components are properly secured before lowering the vehicle.
