Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, torque wrench, socket set, C-clamp or brake caliper tool.
Safety Warning: Ensure the vehicle is on a flat surface and the parking brake is engaged before lifting.

2. Remove Wheel

Loosen lug nuts with a lug wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspect: Check the brake pads for wear and replace if less than 3mm thick.
Remove Caliper: Unbolt the caliper from the bracket using the appropriate socket.
Remove Old Pads: Slide the old brake pads out of the caliper bracket.
Clean Components: Use brake cleaner to remove dust and debris from the caliper and rotor.

4. Install New Brake Pads

Install New Pads: Place the new brake pads into the caliper bracket in the same orientation as the old ones.
Reinstall Caliper: Position the caliper over the new pads and secure it with the bolts. Ensure proper torque specifications (typically around 25-30 lb-ft, but refer to the service manual).

5. Reassemble and Test

Reattach the wheel and tighten lug nuts to the manufacturer’s specifications (typically around 76 lb-ft).
Lower the vehicle and pump the brake pedal to seat the new pads.
Test drive the vehicle at low speeds to ensure proper brake function.
