Solution

1. Preparation

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

2. Inspect Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top up with the appropriate DOT fluid specified in the owner’s manual.
If the fluid is dark or contaminated, it may need to be completely flushed and replaced.

3. Inspect Brake Pads

Remove the wheel using a jack and a socket set.
Inspect the brake pads; they should not be less than 3mm thick. If they are worn down, replace them.
Note any signs of uneven wear, which may indicate issues with calipers or alignment.

4. Inspect Brake Rotors

Check the surface of the rotors for any grooves or scoring. Use a micrometer to measure rotor thickness; replace if below manufacturer specifications.
If the rotors are warped, consider resurfacing or replacing them.

5. Inspect Brake Lines

Visually inspect all brake lines for any leaks or damage.
If leaks are found, replace the affected line. Ensure connections are secure and free of corrosion.

6. Test Brake Components

Reassemble the wheel and lower the vehicle.
Press the brake pedal; it should feel firm and engage smoothly without excessive travel.
Conduct a short test drive to assess braking performance and listen for unusual noises.
