Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Tools Required: Jack and jack stands, socket set, brake fluid, brake bleeder kit, OBD-II scanner.

2. Check and Top Off Brake Fluid

Locate the master cylinder reservoir under the hood.
Remove the cap and check the brake fluid level. If low, add the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
Replace the cap securely.

3. Inspect and Repair Brake Lines

Visually inspect all brake lines and hoses for signs of wear, cracking, or leaks.
If leaks are found, replace damaged sections of the brake line using a brake line repair kit.
Tighten any loose connections to prevent further leakage.

4. Bleed the Brake System

Attach the brake bleeder kit to the brake caliper of the furthest wheel from the master cylinder.
Open the bleeder valve and have an assistant press the brake pedal repeatedly until no more air bubbles appear in the fluid.
Close the bleeder valve before the assistant releases the brake pedal.
Repeat for each wheel, moving from the furthest to the closest to the master cylinder.

5. Inspect Brake Components

Remove the wheel and inspect brake pads and rotors for wear. Replace if pads are less than 3mm thick or if rotors are scored.
If necessary, replace worn brake components with OEM or equivalent parts.
