Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted using jack stands.
Wear appropriate safety gear (gloves, goggles).

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Remove the brake fluid reservoir cap.
2. Inspect the fluid level; if low, top it up with the manufacturer's recommended brake fluid type.
3. If fluid is contaminated, proceed to flush and replace the brake fluid throughout the system.
Tools Required: Brake fluid, funnel, rag for spills.

3. Check for Leaks

Sub-steps:
1. Visually inspect brake lines, hoses, and connections for any signs of leaks.
2. If leaks are found, replace damaged hoses or fittings as necessary.
3. Tighten any loose connections and check for leaks again.
Tools Required: Wrench set, replacement hoses, and fittings.

4. Inspect and Replace Master Cylinder

Sub-steps:
1. Disconnect the battery to prevent electrical shorts.
2. Remove the master cylinder from its mounting using a socket set.
3. Inspect for any signs of internal failure or leaks; replace if necessary.
4. Install the new master cylinder and ensure proper torque on mounting bolts (typically around 15-20 ft-lbs).
Tools Required: Socket set, torque wrench, replacement master cylinder.

5. Inspect Brake Pads and Rotors

Sub-steps:
1. Remove the wheel to access brakes.
2. Inspect brake pads for thickness and surface condition; replace if worn beyond specifications (usually 3mm or less).
3. Check rotors for warping or scoring; replace if needed.
Tools Required: Jack, jack stands, lug wrench, brake caliper tool, replacement brake pads/rotors.
