Solution

1. Preparation

Gather tools and parts required for the brake pad replacement.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent accidental engagement of the brake system.

2. Remove Wheel

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

3. Remove Brake Caliper

Locate the caliper mounting bolts and remove them with a socket wrench.
Carefully slide the caliper off the brake rotor. Do not allow it to hang by the brake line; use a bungee cord or wire to secure it in place.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the caliper for any signs of wear or damage.
If necessary, compress the caliper piston using a brake caliper tool to make room for the new pads.
Install new brake pads in the caliper bracket, ensuring they are properly seated.

5. Reassemble Components

Reattach the brake caliper over the new pads and tighten the caliper mounting bolts to the manufacturer's specified torque (typically around 25-30 Nm).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Steps

Lower the vehicle to the ground and fully tighten the lug nuts to the manufacturer's specified torque (typically around 120 Nm).
Reconnect the battery.
Pump the brake pedal several times to ensure proper pad seating and brake pressure.
