Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Wear safety goggles and gloves for protection.

2. Check and Top Off Brake Fluid

Sub-steps:
- Locate the master cylinder reservoir.
- Remove the cap and check the brake fluid level.
- If low, add the correct type of brake fluid (DOT 3 or DOT 4 as specified).
- Replace the cap securely.

3. Inspect Brake Lines and Hoses

Sub-steps:
- Visually inspect all brake lines for leaks or corrosion.
- Check all brake hoses for cracks, bulges, or signs of wear.
- Replace any damaged components as necessary.

4. Bleed the Brake System

Sub-steps:
- Start at the wheel farthest from the master cylinder (usually rear passenger side).
- Use a brake bleeder kit or a clear tube and a container.
- Have an assistant pump the brake pedal several times and hold it down.
- Loosen the bleeder screw to release air and fluid.
- Tighten the bleeder screw before the assistant releases the brake pedal.
- Repeat until no air bubbles appear, moving to the next wheel in the correct order (rear passenger, rear driver, front passenger, front driver).

5. Inspect and Replace Brake Components

Sub-steps:
- Check the brake pads for thickness; replace if below the manufacturer's minimum specification.
- Inspect rotors for warping or scoring; replace if necessary.
- Install new brake pads and rotors according to manufacturer's specifications.
- Torque all bolts to the specified values using a torque wrench.
