Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear appropriate safety gear, including gloves and safety glasses.

2. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if low, top off with the manufacturer's recommended brake fluid (typically DOT 3 or DOT 4).
If the fluid level is low, check for leaks in the system.

3. Inspect Brake Pads

Remove the wheel to access the brake assembly.
Visually inspect the brake pads; replace if the friction material is less than 3mm thick.
Check for uneven wear and replace pads as needed.

4. Examine Brake Lines and Hoses

Inspect all visible brake lines and hoses for cracks, bulges, or leaks.
Replace any damaged lines or hoses immediately to ensure system integrity.

5. Test Brake Master Cylinder

Check for fluid leaks around the master cylinder.
If there are signs of leakage or if the pedal feels soft, consider replacing the master cylinder.

6. Reassemble and Test

Reattach the wheel and torque the lug nuts to the manufacturer’s specifications.
Lower the vehicle and perform a brake test in a safe area to ensure proper function.
