Solution

1. Preparation

Gather tools and materials: brake pads, jack, jack stands, tire iron, socket set, brake cleaner, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel using a tire iron to access the brake assembly.

3. Remove Old Brake Pads

Locate the caliper bolts and remove them using a socket set.
Slide the caliper off the rotor, being careful not to stretch the brake line.
Remove the old brake pads from the caliper bracket; note their orientation for installation of new pads.

4. Inspect and Clean Components

Inspect the brake rotor for scoring or warping; replace if necessary.
Clean the caliper and bracket with brake cleaner to remove dust and debris.
Apply anti-squeal lubricant on the back of the new brake pads.

5. Install New Brake Pads

Position the new brake pads into the caliper bracket, ensuring proper alignment.
Reinstall the caliper over the new pads and tighten the caliper bolts to manufacturer specifications (typically around 23-30 Nm).

6. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the specified torque (typically 110 Nm).
Reconnect the battery and pump the brake pedal a few times to seat the new pads.
