Solution

1. Preparation

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

2. Inspect and Top Off Brake Fluid

Open the hood and locate the master cylinder.
Remove the cap and check the brake fluid level.
If low, add the appropriate type of brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
Inspect the fluid for contamination; if dirty, proceed to flush the system.

3. Inspect Brake Lines and Components

Visually inspect all brake lines and hoses for cracks, wear, or leaks.
If any leaks are detected, replace the affected brake line or hose.
Inspect brake calipers for leaks; if found, replace the caliper.

4. Bleed the Brake System

Prepare a brake bleeder kit and gather necessary tools.
Starting with the wheel farthest from the master cylinder (usually the right rear), loosen the bleeder valve.
Have an assistant press the brake pedal multiple times and hold it down.
Open the bleeder valve to allow brake fluid and air to escape, then close it before the pedal is released.
Repeat this process for all wheels in the proper order (right rear, left rear, right front, left front).
Check fluid levels and top off as necessary.

5. Replace Worn Components (if necessary)

If brake pads or rotors are found to be worn beyond specifications, replace them.
For brake pads: remove the caliper, replace the pads, and reassemble.
For rotors: remove the caliper and wheel, replace the rotor, and reassemble.
