Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Sub-steps:
1. Use a jack to lift the front or rear of the vehicle, depending on which brakes are being inspected.
2. Secure the vehicle with jack stands.
Tools Required: Hydraulic jack, jack stands.

3. Remove Wheel

Sub-steps:
1. Loosen the lug nuts using a lug wrench.
2. Remove the lug nuts completely and take off the wheel.
Tools Required: Lug wrench.

4. Inspect Brake Pads

Sub-steps:
1. Look at the brake pads through the caliper. Measure the thickness; replace if less than 3mm.
2. Check for uneven wear or damage to the pad surface.
3. Inspect the caliper and rotor for any signs of wear or damage.
Tools Required: Caliper gauge (optional).

5. Replace Brake Pads (if necessary)

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads by sliding them into the bracket, ensuring they are properly seated.
5. Compress the caliper piston using a brake caliper tool to make space for the new pads.
6. Reattach the caliper and torque the bolts to the manufacturer's specifications (usually around 25-35 ft-lbs).
Tools Required: Socket set, brake caliper tool, torque wrench.

6. Reassemble and Lower Vehicle

Sub-steps:
1. Reinstall the wheel and tighten the lug nuts by hand.
2. Lower the vehicle and then torque the lug nuts to the specification (typically around 76 ft-lbs).
Tools Required: Torque wrench.
