Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake fluid, socket set, torque wrench.
Ensure the vehicle is on a flat surface, and engage the parking brake.
Disconnect the battery to avoid any electrical issues during the repair.

2. Inspect Brake Components

Sub-steps:
1. Raise the vehicle using a jack and secure with jack stands.
2. Remove the wheels using a lug wrench.
3. Visually inspect brake pads for thickness; replace if worn below 3mm.
4. Check brake rotors for scoring or warping; replace if necessary.
5. Inspect calipers for leaks or damage; replace any faulty calipers.

3. Replace Brake Pads and Rotors (if necessary)

Sub-steps:
1. Remove the caliper bolts with a socket set and carefully slide the caliper off the rotor.
2. Remove the old brake pads from the caliper bracket.
3. If replacing rotors, remove the rotor by loosening any retaining screws and sliding it off the hub.
4. Install new rotors onto the hub, securing with screws as needed.
5. Install new brake pads into the caliper bracket.
6. Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer's specifications (typically around 25-30 ft-lbs).

4. Bleed the Brake System

Sub-steps:
1. Reconnect the brake fluid reservoir if it was disconnected.
2. Use a brake bleeder kit to remove air from the brake lines.
3. Start at the wheel furthest from the master cylinder (generally the right rear) and work towards the closest (left front).
4. Fill the reservoir with new brake fluid as necessary during the process.
5. Ensure there are no air bubbles in the fluid before closing the bleeder valve.

5. Final Checks

Sub-steps:
1. Reinstall the wheels and lower the vehicle back to the ground.
2. Torque the lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).
3. Reconnect the battery.
