Use a brake fluid tester to check for moisture content in the brake fluid.
4
Inspect the brake pads and rotors for wear or damage.
5
Scan for any error codes related to the braking system using an OBD-II scanner.
6
Perform a brake pedal feel test to assess the pressure and response.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Check and Refill Brake Fluid

Sub-steps:
- Locate the master cylinder reservoir (usually near the driver's side).
- Remove the cap and visually inspect the brake fluid level.
- If low, add the recommended brake fluid type (DOT 3 or DOT 4) until it reaches the full mark.
- Replace the cap securely.

3. Inspect Brake Lines and Components

Sub-steps:
- Visually inspect all brake lines for signs of wear or leaks.
- Check the brake calipers for any fluid leaks or damage.
- If leaks are found, replace the affected brake lines or calipers as necessary.

4. Bleed the Brake System

Sub-steps:
- Attach a clear hose to the bleeder valve on the brake caliper.
- Have an assistant pump the brake pedal several times, then hold it down.
- Open the bleeder valve to release air and old fluid, then close it.
- Repeat until no air bubbles are present in the hose.
- Ensure to check and refill the master cylinder reservoir as needed during this process.

5. Replace Brake Pads or Rotors (if necessary)

Sub-steps:
- Remove the wheel to access the brake components.
- Remove the caliper and bracket.
- Inspect brake pads for thickness; replace if worn beyond specifications.
- Check rotors for grooves or warping; replace if damaged.
- Reassemble with new pads/rotors according to manufacturer specifications.
