Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent accidental electrical issues.

2. Raise Vehicle

Tools Required: Jack and jack stands.
Raise the vehicle using a jack and support it with jack stands.
Remove the wheels to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully lift the caliper off the rotor and secure it with a bungee cord (do not let it dangle from the brake line).
Inspect the brake pads for wear; replace if they are below the minimum thickness (usually 3mm).
Sub-steps:
- Remove the old brake pads.
- Install new brake pads, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

Check rotors for any signs of scoring or warping; replace if damaged.
Tools Required: Torque wrench.
Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install new rotors, ensuring they are clean and free of oil.
Torque the rotor retaining screws to the manufacturer’s specifications.

5. Reassemble Braking System

Reposition the caliper over the new pads and rotor.
Tighten caliper bolts to the specified torque value.
Reinstall the wheel and lower the vehicle.
