Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Raise Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brake pads you are inspecting.
Secure the vehicle with jack stands to ensure stability.

3. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the brake assembly.

4. Inspect Brake Pads

Visually check the brake pads for thickness; they should be at least 1/8 inch thick.
If the pads are worn down to 1/8 inch or less, they need replacement.

5. Replace Brake Pads (if needed)

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor.
Remove the old brake pads from the caliper bracket.
Install new brake pads in the caliper bracket.
Compress the caliper piston using a brake caliper tool to allow new pads to fit.
Reattach the caliper over the new pads and secure it with the caliper bolts to manufacturer specifications (typically 25-35 ft-lbs).

6. Reattach Wheel

Place the wheel back on the hub.
Hand-tighten the lug nuts, then lower the vehicle and torque the lug nuts to manufacturer specifications (usually 80-100 ft-lbs).

7. Test Brakes

Pump the brake pedal several times to ensure proper brake engagement.
Test drive the vehicle at low speed to ensure brakes are functioning correctly.
