Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety while working on the braking system.

2. Remove Wheel

Use a jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts with a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the brake caliper bolts using a socket set.
- Carefully slide the caliper off the rotor and support it using a bungee cord (do not let it hang by the brake line).
- Remove the old brake pads from the caliper bracket.
- Compare new brake pads with old ones to ensure correct fitment.
- Install new brake pads ensuring they are aligned properly in the caliper bracket.

4. Inspect and Clean Brake Rotors

Sub-steps:
- Check the rotor surface for wear and warping by using a micrometer and a straight edge.
- If needed, resurface or replace the rotors.
- Clean the rotor surface with brake cleaner to remove dust and contaminants.

5. Check Caliper Functionality

Sub-steps:
- Inspect the caliper slides for proper movement and lubrication.
- Apply brake grease to the caliper slides if necessary.
- If the caliper is seized, replace it with a new unit.

6. Reassemble Components

Sub-steps:
- Reinstall the caliper over the new brake pads and secure it with the caliper bolts.
- Replace the wheel and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.

7. Final Checks

Reconnect the battery and pump the brake pedal a few times to seat the new pads.
Check brake fluid level and top off if necessary.
