Solution

1. Preparation

Gather tools and parts, and park the vehicle on a level surface.
Ensure the parking brake is engaged and the engine is off.
Safety goggles and gloves are recommended.

2. Inspect and Repair Leaks

Tools Required: Wrench set, brake line tool
Check all brake lines for leaks. If found:
- Use the wrench to loosen the fittings.
- Replace damaged sections of the brake line or fittings as necessary.
- Ensure all connections are tight after replacement.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing, jar
To remove air from the brake lines:
- Start at the wheel farthest from the master cylinder (usually the right rear).
- Attach clear tubing to the bleeder screw and place the other end into the jar.
- Have an assistant pump the brake pedal several times, then hold it down.
- Open the bleeder screw to release air and fluid, then close it before the pedal is released.
- Repeat until no air bubbles are visible, then proceed to the next wheel.
- Continue to the left rear, right front, and finally left front.

4. Replace the Brake Fluid

Tools Required: Brake fluid, funnel
If the brake fluid is contaminated or low:
- Remove the master cylinder cap and use a funnel to fill it with new brake fluid (DOT 3 or DOT 4 as specified).
- Replace the cap securely.

5. Inspect and Replace Components

Tools Required: Socket set, torque wrench
If the brake pads or rotors are worn:
- Remove the wheel and inspect the components.
- Replace brake pads and/or rotors if they are below minimum thickness or damaged.
- Reassemble, ensuring to torque bolts to manufacturer specifications.
