Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Check and Top Off Brake Fluid

Tools Required: Brake fluid, funnel
Check the brake fluid level in the master cylinder.
If low, add the recommended type of brake fluid (DOT 3 or DOT 4 as specified by the manufacturer).

3. Inspect and Repair Leaks

Tools Required: Wrench set, brake line tool
Visually inspect brake lines, calipers, and connections for leaks.
Tighten any loose fittings or replace damaged brake lines or calipers as needed.

4. Bleed the Brake System

Tools Required: Brake bleeder kit or clear tubing, catch container
Start with the wheel farthest from the master cylinder (right rear), then move to left rear, right front, and finally left front.
Attach the tubing to the bleeder valve and submerge it in the catch container.
Have an assistant pump the brake pedal several times, then hold it down while you open the bleeder valve to release air and fluid.
Close the valve and repeat until no air bubbles are seen.
Ensure to keep the master cylinder topped up during the process.

5. Replace Worn Brake Components

Tools Required: Socket set, torque wrench
If brake pads or rotors are worn beyond specifications, remove the wheel and caliper.
Remove the old pads and measure rotor thickness; replace if below minimum specifications.
Install new pads and reassemble the caliper, ensuring to torque bolts to manufacturer specifications.

6. Final Assembly and Testing

Reinstall the wheel and lower the vehicle.
Pump the brake pedal several times to ensure proper feel before driving.
Conduct a test drive to confirm the brakes are functioning properly.
