Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the braking system.

2. Check Brake Fluid Level

Open the master cylinder reservoir cap.
Inspect the fluid level; if low, top up with manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Replace the cap securely.

3. Inspect for Leaks

Visually inspect all brake lines, hoses, and connections for signs of fluid leaks.
If leaks are found, replace the damaged components.
Ensure all connections are tight.

4. Bleed the Brake System

Start at the wheel farthest from the master cylinder (right rear).
Use a brake bleeder kit or a helper to pump the brake pedal.
Open the bleeder valve to allow fluid and air to escape until clear fluid flows.
Close the valve and repeat on the left rear, then right front, and finally left front.
Ensure the master cylinder reservoir remains filled during this process.

5. Inspect and Replace Components (if necessary)

If brake pads or rotors are worn, replace them according to manufacturer specifications.
Reassemble any removed components and ensure proper torque specifications are followed (typically 75-100 ft-lbs for caliper bolts).
