4
Inspect brake lines for corrosion or punctures.

Solution

1. Preparation

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

2. Inspect the Brake Fluid Reservoir

Locate the brake fluid reservoir under the hood.
Clean the area around the reservoir cap to prevent contamination.
Remove the cap and check the fluid level; add new brake fluid if necessary.

3. Identify and Repair Leaks

Inspect brake lines and hoses for any signs of leaks or damage.
If leaks are found, replace the affected brake lines or hoses as necessary.
For leaks at the master cylinder or calipers, replace the respective components.

4. Replace Brake Pads and Rotors (if necessary)

Remove the wheel to access the brake assembly.
Unbolt the caliper and remove it from the rotor.
Inspect brake pads for thickness; replace if worn below specifications.
Inspect rotors for warping or excessive wear; replace if necessary.

5. Refill and Bleed Brake System

Refill the brake fluid reservoir with the appropriate type of brake fluid (DOT 3 or DOT 4).
Bleed the brake system to remove air bubbles, starting from the wheel farthest from the master cylinder.
Ensure all air is purged from the system to restore proper brake function.
