Solution

1. Preparation

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

2. Check and Top Off Brake Fluid

Tools Required: Brake fluid, funnel
Remove the master cylinder cap and inspect the brake fluid level. If low, add the appropriate type of brake fluid (DOT 3 or DOT 4, as specified by the manufacturer).
Replace the cap securely.

3. Inspect Brake Lines

Tools Required: Visual inspection tools (flashlight), wrench set
Inspect brake lines for any signs of damage or leaks.
Tighten any loose connections and replace damaged lines as necessary.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, clean rags
Start with the wheel farthest from the master cylinder (usually the right rear).
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve on the brake caliper; allow fluid to flow until no air bubbles are visible, then close the valve.
Repeat this process for each wheel in the correct order (right rear, left rear, right front, left front).
Check fluid levels throughout the bleeding process and top off as needed.

5. Replace Brake Pads and Rotors (if required)

Tools Required: Socket set, torque wrench, brake caliper tool
Remove the wheel and inspect the brake pads and rotors.
If worn beyond specifications, remove the caliper by unscrewing the mounting bolts.
Replace the pads and rotors, ensuring to apply brake grease to the backing plates of the new pads.
Reassemble and torque bolts to manufacturer's specifications.
