Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety gloves and goggles.

2. Check and Replenish Brake Fluid

Tools Required: Brake fluid, funnel
Instructions:
1. Open the hood and locate the brake master cylinder reservoir.
2. Check the fluid level; add the correct type of brake fluid (DOT 3 or DOT 4) if low.
3. Close the reservoir cap securely.

3. Inspect and Repair Leaks

Tools Required: Wrench set, brake line repair kit (if necessary)
Instructions:
1. Visually inspect all brake lines, calipers, and wheel cylinders for leaks.
2. Tighten any loose connections.
3. Replace any damaged or corroded brake lines or components as needed.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, clear tubing
Instructions:
1. Start with the brake farthest from the master cylinder (usually the right rear).
2. Attach the clear tubing to the bleeder valve on the brake caliper and place the other end in a container.
3. Have an assistant press the brake pedal while you open the bleeder valve to allow air and fluid to escape.
4. Close the valve before the assistant releases the brake pedal and repeat until no air bubbles are present.
5. Repeat for the remaining brakes in the correct order.

5. Inspect Brake Components

Tools Required: Jack and jack stands, socket set
Instructions:
1. Lift the vehicle and secure it on jack stands.
2. Remove the wheels to access brake pads and rotors.
3. Check brake pad thickness; replace if below specifications.
4. Measure rotor thickness and look for any scoring or damage; replace if necessary.
