Solution

1. Preparation

Gather necessary tools and parts before starting.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Check and Replace Brake Fluid

Tools Required: Brake fluid, funnel, clean cloth
Sub-steps:
1. Open the brake fluid reservoir cap and inspect the fluid; if it is dark or contaminated, it needs replacement.
2. Using a funnel, pour fresh brake fluid into the reservoir until it reaches the maximum level.
3. Replace the reservoir cap securely.

3. Inspect and Repair Brake Lines

Tools Required: Wrench set, brake line tool
Sub-steps:
1. Visually inspect all brake lines for signs of wear, corrosion, or leaks.
2. If any leaks are found, replace the damaged brake line using the wrench set to disconnect and install new lines.
3. Ensure all connections are tight and free of leaks.

4. Bleed the Brakes

Tools Required: Brake bleeder kit, clear tubing, container for old fluid
Sub-steps:
1. Attach clear tubing to the bleeder valve on the brake caliper and place the other end into the container.
2. Have an assistant pump the brake pedal several times and hold it down.
3. Open the bleeder valve to release air and old fluid, then tighten the valve before the assistant releases the pedal.
4. Repeat this process for all four brakes until clear fluid without bubbles flows from each caliper.
5. Check and top off the brake fluid reservoir as needed.

5. Inspect and Replace Brake Pads and Rotors (if necessary)

Tools Required: Jack, jack stands, socket set, torque wrench
Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the brake components.
3. Inspect brake pads for thickness; replace if they are below manufacturer specifications.
4. Check rotors for wear and warping; replace if necessary.
5. Install new pads and rotors, ensuring to torque any bolts to manufacturer specifications.
