Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Check Brake Fluid Level

Remove the master cylinder cap.
Inspect the brake fluid level; if low, add the appropriate DOT brake fluid to the recommended level.
If fluid is low, investigate for leaks before sealing the cap.

3. Inspect for Leaks

Visually inspect all brake lines and connections for signs of fluid leakage.
Check the brake calipers and master cylinder for any signs of fluid seeping out.
Tighten any loose connections and replace any damaged components as needed.

4. Inspect Brake Components

Remove the wheel to access the brake assembly.
Check the brake pads for thickness; replace if they are below 3mm.
Inspect the rotors for scoring or warping; resurface or replace as necessary.

5. Bleed the Brake System

Using a brake bleeder kit, start with the wheel farthest from the master cylinder (usually the rear passenger).
Attach a hose from the bleeder valve to a container and open the valve while a helper presses the brake pedal.
Close the valve before the pedal is released to prevent air from entering. Repeat until no air bubbles are visible in the fluid.
Repeat this process for each wheel in the proper order (rear passenger, rear driver, front passenger, front driver).
