Solution

1. Preparation

Gather necessary tools and parts.
Safely lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.

Tools Required:

Jack and jack stands
Lug wrench
Socket set
Torque wrench
Brake cleaner
Wire brush

2. Remove Brake Components

Sub-step 1: Unbolt the caliper using the socket set; support it with a bungee cord or wire to avoid stress on the brake line.
Sub-step 2: Remove the brake pads from the caliper bracket.
Sub-step 3: If necessary, unbolt and remove the caliper bracket for better access to the rotor.
Sub-step 4: Inspect the brake rotor; if replacement is needed, remove the rotor by unscrewing any retaining screws and sliding it off the hub.

3. Inspect and Replace Components

Sub-step 1: Check the brake pads; replace them if they are worn down (less than 3mm thickness) or damaged.
Sub-step 2: If the rotor is damaged, resurface it if within specifications or replace it with a new rotor.
Sub-step 3: Clean the new rotor with brake cleaner and install it onto the hub if replaced.
Sub-step 4: Reinstall the caliper bracket and torque the bolts to manufacturer specifications.

4. Reassemble and Test

Sub-step 1: Reinstall the brake pads into the caliper and reattach the caliper to the bracket.
Sub-step 2: Ensure all bolts are tightened to the correct torque settings.
Sub-step 3: Reinstall the wheel and lower the vehicle.
Sub-step 4: Pump the brake pedal a few times to seat the pads before driving.
