Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect Brake Fluid

Remove the brake fluid reservoir cap.
Check the fluid level; top up with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
If the fluid appears dark or contaminated, proceed to replace it.

3. Bleed the Brake Lines

Reconnect the negative battery terminal.
Start with the wheel farthest from the master cylinder (right rear, left rear, right front, left front).
Use a brake bleeder kit or a helper to press the brake pedal.
Open the bleeder screw on the brake caliper, allowing fluid and air to escape until no bubbles are seen.
Close the bleeder screw before releasing the brake pedal.
Repeat until all calipers are bled, ensuring the brake fluid reservoir does not run dry.

4. Inspect and Replace Brake Components (if necessary)

Check brake pads and rotors for wear; replace if they are below the manufacturer's specifications.
If the master cylinder is leaking or failing, remove it and replace it with a new unit, ensuring to bench bleed it before installation.

5. Final Checks

Refill the brake fluid reservoir to the recommended level.
Recheck all connections and ensure there are no leaks.
Test drive the vehicle to ensure the brake pedal feels firm and responsive.
