Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake fluid, clean rags.
Sub-steps:
- Ensure the vehicle is parked on a flat surface and the ignition is off.
- Engage the parking brake for safety purposes.

2. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Remove the wheel using the lug wrench.
2. Unbolt the brake caliper and support it without stressing the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper for any damage or leaks.
5. Install new brake pads, ensuring they are aligned properly.
6. Reattach the caliper and tighten bolts to the manufacturer’s torque specifications.

3. Inspect and Resurface/Replace Rotors

Tools Required: Brake rotor gauge, brake cleaner.
Sub-steps:
1. Remove the brake rotor from the hub by unbolting it.
2. Measure rotor thickness and check for warping.
3. If the rotor is within specifications, clean it thoroughly with brake cleaner.
4. If worn beyond specs, replace with new rotors.
5. Reinstall the rotor and secure it properly.

4. Bleed the Brake System

Tools Required: Brake bleeder kit.
Sub-steps:
1. Attach the brake bleeder kit to the brake bleeder valve on the caliper.
2. Have an assistant pump the brake pedal and hold it down.
3. Open the bleeder valve to release air and fluid, then close it before the pedal is released.
4. Repeat until no air bubbles are visible in the fluid.
5. Check brake fluid level in the reservoir and top off as necessary.
