Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Engage the parking brake for added safety.

2. Address Brake Fluid Level

Sub-step 1: Open the hood and locate the master brake cylinder.
Sub-step 2: Check the brake fluid level; if low, top it off with the recommended brake fluid type (DOT 3 or DOT 4).
Sub-step 3: Inspect for any signs of contamination or discoloration in the fluid.

3. Inspect Brake Components

Sub-step 1: Remove the wheel to access the brake components.
Sub-step 2: Examine the brake pads for thickness; replace if worn below 3mm.
Sub-step 3: Check the brake rotors for scoring or warping; machine or replace as necessary.

4. Check for Leaks

Sub-step 1: Inspect all brake lines for signs of fluid leaks.
Sub-step 2: Look for leaks around the calipers and wheel cylinders.
Sub-step 3: Tighten any loose fittings or replace damaged lines as needed.

5. Test Brake System

Sub-step 1: Reinstall the wheel and lower the vehicle.
Sub-step 2: Start the engine and pump the brake pedal to build pressure.
Sub-step 3: Perform a brake test at low speed to ensure proper functionality.
