Solution

1. Preparation

Gather tools and parts needed for the repair.
Safely lift the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the brake components.

2. Inspect and Replace Brake Pads

Tools Required: Socket set, brake cleaner, torque wrench, C-clamp.
Remove the caliper bolts using a socket.
Carefully slide the caliper off the rotor, supporting it with a bungee cord or similar device to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the brake pad backing for wear indicators. If the pads are worn down to the indicator, they need replacement.
Clean the caliper bracket and install new brake pads, ensuring they are properly seated.

3. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Brake rotor puller (if stuck), torque wrench.
Check the rotor surface for grooves or excessive wear.
If the rotor is damaged, remove the rotor by unscrewing any retaining screws and pulling it off the hub.
Install new rotors, ensuring they are oriented correctly and secure any retaining screws.
Torque the rotor to the manufacturer's specifications.

4. Reassemble and Test

Reinstall the caliper over the new brake pads, compressing the pistons slightly with a C-clamp if necessary.
Tighten the caliper bolts to the specified torque.
Reattach the wheel and lower the vehicle.
Pump the brake pedal to reset the brake pad position before testing.
