Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative terminal of the battery for safety.

2. Inspect Brake Pads and Rotors

Remove the wheel using a socket set.
Examine brake pads for thickness; replace if less than 3mm.
Check rotors for warping or scoring; resurface or replace if necessary.

3. Check Brake Fluid

Locate the brake fluid reservoir and inspect the fluid level.
If low, top off with the manufacturer-recommended brake fluid.
If the fluid is contaminated, flush the brake system and replace with fresh fluid.

4. Inspect Suspension and Drivetrain Components

Visually inspect suspension components such as control arms and bushings for wear.
Check the condition of the driveshaft and CV joints for any play or damage.
Replace any worn components as needed.

5. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Reconnect the battery terminal.
Test drive the vehicle to confirm the issue is resolved and observe brake performance.
