Solution

1. Preparation

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

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Remove the cap and inspect the fluid condition; if it appears dark or contaminated, proceed to replace it.
3. Use a turkey baster or siphon to remove old brake fluid from the reservoir.
4. Refill with new, manufacturer-recommended brake fluid (DOT 3 or DOT 4 as specified).

3. Locate and Repair Leaks

Sub-steps:
1. Visually inspect all brake lines for cracks, corrosion, or damage.
2. Tighten any loose connections and replace any damaged lines or fittings.
3. If leaks are found at calipers or wheel cylinders, replace those components as necessary.

4. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads for wear; replace if the thickness is below the manufacturer's specification (usually around 3mm).
3. Install new brake pads, ensuring they are properly aligned and secured.

5. Inspect and Replace Master Cylinder

Sub-steps:
1. Check the master cylinder for leaks and ensure the seals are intact.
2. If a leak is present, remove the master cylinder by unbolting it from the brake booster.
3. Replace with a new master cylinder, ensuring proper alignment and torque specifications are followed.
