Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Wear safety gloves and goggles for protection.

2. Raise Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on which brake pads you are checking.
Secure the vehicle with jack stands to prevent accidental lowering.

3. Remove Wheel

Use a socket set to remove the lug nuts from the wheel.
Carefully take off the wheel and set it aside.

4. Inspect Brake Pads

Examine the brake pads for thickness; they should be at least 3mm thick.
If they are thin, proceed to replace them.
Check the brake pad wear indicator; if it is worn down, replacement is necessary.

5. Replace Brake Pads (if necessary)

Remove the caliper by loosening the caliper bolts with a socket wrench.
Carefully slide the caliper off the rotor and support it using a bungee cord or a suitable hook to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Install the new brake pads by sliding them into the caliper bracket.
Reinstall the caliper over the new pads and tighten the caliper bolts to the manufacturer’s torque specifications (typically around 30 Nm).

6. Reassemble

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (typically around 120 Nm).

7. Final Checks

Pump the brake pedal a few times to ensure the pads seat properly against the rotor.
Check the brake fluid level and top off if necessary.
