Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is off.
Gather necessary tools and parts.
Disconnect the battery to avoid any electrical issues.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Use a socket set to remove the caliper mounting bolts.
3. Carefully slide the caliper off the rotor and support it with a bungee cord or similar tool.
4. Remove the old brake pads from the caliper bracket.
5. Inspect the caliper for any sticking or damage; replace if necessary.
6. Install new brake pads, ensuring they are properly seated.
7. Reattach the caliper and torque the mounting bolts to the manufacturer’s specifications (usually around 30-40 Nm).

3. Check and Replace Brake Rotors (if necessary)

Sub-steps:
1. If rotors are warped or scored, remove them by unscrewing the retaining screws.
2. Clean the hub surface where the rotor mounts to remove rust and debris.
3. Install new rotors, ensuring they are properly aligned.
4. Torque the rotor retaining screws to the specified torque (typically around 10-15 Nm).

4. Bleed the Brake System

Sub-steps:
1. Reconnect the battery.
2. Use a brake bleeder kit to remove air from the brake lines.
3. Start at the wheel farthest from the master cylinder (usually the passenger rear).
4. Open the bleeder valve and pump the brake pedal until fluid flows without bubbles, then close the valve.
5. Repeat for the other wheels in the correct order (rear passenger, rear driver, front passenger, front driver).
