Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely supported with jack stands.
Wear safety goggles and gloves for protection.

2. Inspect and Replace Brake Fluid

Sub-step 1: Remove the master cylinder cap and check the brake fluid level.
Sub-step 2: If fluid is low, add new brake fluid that meets the manufacturer's specifications (typically DOT 3 or DOT 4).
Sub-step 3: If fluid is contaminated, proceed to flush the brake system.

3. Bleed the Brake System

Sub-step 1: Begin at the wheel farthest from the master cylinder (usually rear passenger side).
Sub-step 2: Attach a clear hose to the bleeder valve on the brake caliper and place the other end in a container.
Sub-step 3: Have an assistant pump the brake pedal several times and hold it down.
Sub-step 4: Open the bleeder valve to allow fluid and air to escape, then close the valve before your assistant releases the pedal.
Sub-step 5: Repeat until no bubbles are visible in the fluid. Move to the next wheel in the order: rear driver side, front passenger side, and finally front driver side.

4. Inspect and Replace Brake Components (if necessary)

Sub-step 1: If brake pads are worn, remove the caliper and replace pads with new ones.
Sub-step 2: Check rotors for warping or damage; replace if necessary.
Sub-step 3: Inspect brake lines for leaks; replace any damaged lines.
