Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Loosen the lug nuts on the wheels before lifting the vehicle.

2. Lift Vehicle and Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts using a socket set.
Slide the caliper off the rotor and support it with a bungee cord (do not let it dangle).
Remove old brake pads from the caliper bracket.
Inspect the caliper guide pins for lubrication; replace or lubricate as necessary.
Install new brake pads in the caliper bracket, ensuring correct orientation.

4. Reassemble and Bleed Brakes

Reinstall the caliper over the new pads and tighten the caliper bolts to manufacturer specifications (typically around 25-30 Nm).
If brake fluid was lost, bleed the brake system using a brake bleeder kit.
Reattach the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Test

Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to the specified torque (typically around 100 Nm).
Start the vehicle and pump the brake pedal several times to seat the new pads.
