Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the 12V battery to prevent electrical issues while working.

2. Remove the Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Use a socket set to remove the lug nuts and take off the wheel.

3. Inspect Brake Pads

Locate the brake caliper and its mounting bolts.
Use a socket wrench to remove the caliper from its bracket.
Carefully slide the caliper off the rotor without disconnecting the brake line.
Measure the thickness of the brake pads. Replace if they are less than 3mm thick.

4. Replace Brake Pads (if necessary)

Remove the old brake pads from the caliper.
Compress the caliper piston using a brake tool or C-clamp to create space for the new pads.
Insert new brake pads into the caliper bracket.
Reinstall the caliper over the new pads and tighten bolts to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and lug nuts, then lower the vehicle.
Reconnect the battery and ensure all tools are removed from the area.
Perform a test drive to ensure brakes function properly.
