Solution

1. Preparation

Gather tools: socket set, brake fluid, brake bleeder kit, wrench set.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Disconnect the battery to prevent any electrical issues.

2. Check and Refill Brake Fluid

Open the hood and locate the master cylinder.
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 for Leaks

Visually inspect all brake lines, connections, and the master cylinder for any signs of leakage.
If leaks are found, replace the damaged brake lines or components as necessary.
Tighten any loose connections and ensure seals are intact.

4. Bleed the Brake System

Using a brake bleeder kit, start with the wheel farthest from the master cylinder (usually the rear passenger side).
Attach the bleeder hose to the brake caliper and submerge the other end in a container with brake fluid.
Have an assistant press the brake pedal while you open the bleeder valve. Close the valve before they release the pedal.
Repeat until no air bubbles appear in the fluid stream, then move to the next wheel (rear driver side, front passenger side, front driver side).
Ensure the master cylinder does not run low during the process, adding fluid as necessary.

5. Inspect Brake Components

Remove the wheel to access brake pads and rotors.
Check the condition of brake pads; replace if they are worn down to the wear indicators.
Inspect rotors for grooves or scoring; resurface or replace if damaged.
