Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely supported with jack stands.
Disconnect the battery to prevent electrical issues.

2. Check and Refill Brake Fluid

Locate the master cylinder reservoir.
Inspect the brake fluid level; if low, add the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
If fluid was added, check for leaks in the system.

3. Inspect Brake Lines and Hoses

Visually examine all brake lines and hoses for signs of wear, cracks, or leaks.
Replace any damaged hoses or lines with parts that meet OEM specifications.

4. Brake Pad and Rotor Inspection

Remove the wheel using a lug wrench.
Inspect brake pads for thickness; replace if less than 3mm.
Check rotors for warping or excessive wear; if necessary, resurface or replace them.

5. Bleed the Brake System

Reconnect the battery.
Have an assistant pump the brake pedal several times until it feels firm.
Use a brake bleeder kit to bleed each brake caliper, starting with the caliper farthest from the master cylinder.
- Open the bleed screw, have the assistant press the brake pedal, and close the screw before they release the pedal.
- Repeat until no air bubbles are present in the fluid.
