Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.

Tools Required:

Brake fluid
Wrench set
Brake bleeder kit
Jack and jack stands
Torque wrench

2. Inspect and Repair Brake Lines

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Visually inspect brake lines for any signs of wear or leaks.
3. If a leak is found, replace the damaged brake line.
4. Tighten any loose connections to prevent future leaks.

3. Check Brake Fluid Levels

Sub-steps:
1. Open the brake fluid reservoir cap.
2. If the fluid is low, top up with the manufacturer-recommended brake fluid.
3. Inspect for any signs of contamination in the fluid.

4. Bleed the Brake System

Sub-steps:
1. Start at the furthest brake from the master cylinder (usually the passenger side rear).
2. Attach the brake bleeder kit to the bleeder valve on the brake caliper.
3. Have an assistant press the brake pedal while you open the bleeder valve.
4. Close the valve before the pedal is fully released to avoid sucking air back in.
5. Repeat this process until no air bubbles are visible in the fluid.
6. Move to the next brake and repeat until all brakes are bled.

5. Reassemble and Test

Sub-steps:
1. Reinstall the brake fluid reservoir cap securely.
2. Lower the vehicle from the jack stands.
3. Start the vehicle and gently press the brake pedal to ensure it feels firm.
4. Test drive the vehicle at low speeds to confirm brakes are functioning properly.
