Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety.
Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Remove Wheel

Use a jack to raise the vehicle and support it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-step 1: Remove the caliper bolts with a socket wrench.
Sub-step 2: Slide the caliper off the brake rotor and secure it with a bungee cord to avoid stress on the brake line.
Sub-step 3: Remove the old brake pads from the caliper bracket.
Sub-step 4: Install new brake pads, ensuring they are oriented correctly.
Sub-step 5: Reinstall the caliper over the new pads and tighten caliper bolts to the manufacturer’s torque specifications.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-step 1: If rotors are scored or warped, remove the rotor by unscrewing the retaining screws.
Sub-step 2: Clean the hub surface and install new rotors, aligning them properly.
Sub-step 3: Secure the new rotors with retaining screws.

5. Reassemble and Test

Reinstall the wheel and tighten the lug nuts in a crisscross pattern to the proper torque.
Reconnect the battery.
Lower the vehicle and perform a test of the brake system.
