Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
- Open the master cylinder reservoir cap and check the fluid level.
- If low, top off with the manufacturer's recommended brake fluid type (usually DOT 4).
- Replace the cap securely.

3. Inspect and Repair Brake Lines

Tools Required: Wrench set, brake line wrench
- Visually inspect all brake lines for cracks, corrosion, or leaks.
- If any leaks are found, replace the damaged section of the brake line.
- Ensure all fittings are tightened to the manufacturer's specifications to prevent leaks.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing
- Start with the wheel farthest from the master cylinder (usually rear passenger).
- Attach the clear tubing to the bleeder valve on the brake caliper.
- Open the bleeder valve and have an assistant press the brake pedal.
- Close the valve before the pedal reaches the floor and repeat until no bubbles appear in the fluid.
- Repeat for each wheel in the correct order (rear passenger, rear driver, front passenger, front driver).

5. Inspect Brake Components

Tools Required: Brake caliper tool, torque wrench
- Remove the wheel to access the brake components.
- Inspect brake pads for thickness; replace if worn below the minimum specification.
- Inspect rotors for warping or damage; resurface or replace if necessary.
- Reassemble the brake components and torque to manufacturer specifications.
