Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the braking system.

2. Remove Wheel

Use a jack to lift the vehicle and support it with jack stands.
Remove the lug nuts with a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Brake pad spreader, torque wrench.
Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor.
Remove old brake pads from the caliper bracket.
Check the condition of the shims and replace if necessary.
Install new brake pads in the bracket.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are scored or warped, remove them by unscrewing the retaining screws.
Clean the hub surface before installing new rotors.
Install new rotors and secure them with screws.

5. Reassemble Brake Components

Reinstall the caliper over the new brake pads and secure it with caliper bolts.
Use a torque wrench to tighten to manufacturer specifications (usually around 20-30 ft-lbs, but check specifications).
Reinstall the wheel and lug nuts, tightening to the proper torque specifications (typically 80-100 ft-lbs).

6. Final Checks

Reconnect the battery.
Pump the brake pedal to ensure the pads seat against the rotors properly before driving.
