Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake caliper tool, torque wrench, brake cleaner, and safety goggles.
Sub-steps:
1. Park the vehicle on a flat surface and engage the parking brake.
2. Wear safety goggles for eye protection.
3. Loosen the lug nuts on the front or rear wheels slightly before raising the vehicle.

2. Raise the Vehicle

Sub-steps:
1. Use a jack to lift the vehicle at the designated jacking points.
2. Secure the vehicle on jack stands to ensure stability.
3. Remove the wheels using the lug wrench.

3. Remove Brake Caliper

Sub-steps:
1. Locate the caliper bolts and remove them using the socket set (usually 13mm or 15mm).
2. Carefully slide the caliper off the rotor and support it with a wire or bungee cord to avoid straining the brake line.

4. Replace Brake Pads

Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Use a brake caliper tool to compress the caliper piston back into the housing to accommodate the new pads.
3. Place the new brake pads in the caliper bracket, ensuring they are seated correctly.

5. Reassemble Components

Sub-steps:
1. Slide the caliper back over the new pads and align it with the bracket.
2. Reinstall and tighten the caliper bolts to the manufacturer’s specified torque (usually around 25-30 Nm).
3. Reattach the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Steps

Sub-steps:
1. Carefully lower the vehicle back to the ground.
2. Tighten the lug nuts to the manufacturer’s specified torque (usually around 120 Nm).
3. Pump the brake pedal a few times to ensure the brake pads are seated and the pedal feels firm.
