Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Wheel Removal

Using a jack, lift the vehicle and secure it on jack stands.
Remove the wheel using a socket set.
Tools Required: Jack, jack stands, socket set.

3. Brake Rotor Inspection

Inspect the brake rotor for warping using a dial indicator.
- If the rotor is warped, proceed to replace it.
Clean the rotor surface with brake cleaner if it is scored but usable.

4. Brake Pad Inspection and Replacement

Remove the caliper bolts with a socket set.
Lift the caliper away from the rotor and secure it (do not let it hang from the brake line).
Remove the old brake pads and inspect them for wear.
Replace with new brake pads if necessary.
Tools Required: Socket set, brake cleaner, caliper tool (for compressing pistons).

5. Reassemble Components

Reinstall the caliper over the new brake pads.
Tighten caliper bolts to manufacturer's specified torque (usually around 25-30 Nm).
Reinstall the wheel and lower the vehicle.
