Solution

1. Preparation

Tools Required: Wrench set, brake fluid tester, OBD-II scanner, clean rags.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Wear safety goggles and gloves for protection.

2. Inspect and Refill Brake Fluid

Locate the master cylinder reservoir (usually near the driver's side).
Check the brake fluid level; if it's low, add the appropriate DOT fluid (refer to owner's manual for specifications).
If fluid is dirty or contaminated, proceed to flush the brake system.

3. Bleed the Brake System

Start by securing the vehicle with wheel chocks and jack stands.
Remove the tire to access the brake calipers.
Locate the bleeder valve on each brake caliper.
Using a wrench, open the bleeder valve and have an assistant press the brake pedal slowly.
Close the valve before the pedal reaches the floor. Repeat until clear fluid comes out.
Top off the brake fluid in the master cylinder as needed during the process.

4. Inspect Brake Components

Check brake lines for any signs of wear, damage, or leaks.
Inspect brake pads and rotors for wear; replace if necessary.
Examine the brake booster for any signs of air leaks or malfunction.
