Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a flat surface and securely lifted with jack stands.
Wear safety gloves and goggles.

2. Inspect and Fill Brake Fluid

Tools Required: Brake fluid, funnel
Check the brake fluid level in the master cylinder reservoir.
If low, add the appropriate type of brake fluid (DOT 3 or DOT 4, as specified in the owner’s manual).

3. Check for Leaks

Tools Required: Flashlight
Visually inspect brake lines, calipers, and wheel cylinders for signs of fluid leaks.
If leaks are found, replace the damaged components (e.g., brake lines, calipers).

4. Bleed Brake Lines

Tools Required: Brake bleeder kit, wrench, container for old fluid
Start with the wheel furthest from the master cylinder (usually the passenger rear).
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve on the brake caliper, allowing air and fluid to escape. Close the valve before the pedal is released.
Repeat until no air bubbles are visible in the fluid.
Move to the next wheel in order (driver rear, passenger front, driver front) and repeat the process.
Ensure brake fluid level in the master cylinder remains full throughout bleeding.

5. Replace Worn Components (if necessary)

If the brake pads or rotors are worn beyond specifications, replace them.
Tools Required: Socket set, torque wrench
Remove the wheel and caliper, replace pads or rotors, and reassemble, ensuring proper torque specifications are followed.
