Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and goggles for protection.

2. Check Brake Fluid

Open the hood and locate the brake fluid reservoir.
Remove the cap and inspect the fluid level. If low, top it off with the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
If the fluid is contaminated (dark or has particles), proceed to replace the fluid.

3. Inspect for Leaks

Visually inspect all brake hoses, lines, and connections for signs of leakage or wear.
If leaks are found, replace the affected components. Use a wrench to disconnect the damaged line and install a new one, ensuring all connections are tight.

4. Bleed the Brake System

Start at the wheel farthest from the master cylinder (usually the passenger rear wheel).
Attach a brake bleeder kit or clear tubing to the bleeder valve.
Have an assistant pump the brake pedal several times, then hold it down.
Open the bleeder valve to allow air and old fluid to escape. Close the valve before the pedal is released.
Repeat until no air bubbles are present in the fluid.
Move to the next wheel, following the order: passenger rear, driver rear, passenger front, driver front.

5. Test and Finalize

After bleeding all brakes, check the brake fluid level again and top off if necessary.
Replace the brake fluid reservoir cap securely.
Perform a test drive to ensure the brake pedal feel is firm and responsive.
