Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Wheel

Use a lug wrench to loosen the wheel nuts slightly before lifting the vehicle.
Lift the vehicle using a jack and secure it with jack stands.
Completely remove the wheel nuts and take off the wheel.

3. Remove Brake Caliper

Locate the caliper mounting bolts and remove them using a socket set.
Carefully slide the caliper off the brake rotor.
Support the caliper using a bungee cord or rope to avoid straining the brake line.

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and inspect for damage or corrosion.
Install new brake pads, ensuring they are properly seated in the bracket.

5. Reassemble Brake Components

Slide the caliper back over the new brake pads.
Reinstall the caliper mounting bolts and torque them to the manufacturer’s specification (typically around 25-35 ft-lbs, but verify with repair manual).
Reinstall the wheel and torque the lug nuts to the manufacturer’s specification (typically around 100-110 ft-lbs).

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Pump the brake pedal several times to seat the pads.
Test the brakes at low speed to ensure proper function.
