Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, C-clamp or brake caliper tool, torque wrench, safety glasses, gloves.
Sub-steps:
1. Park the vehicle on a level surface and engage the parking brake.
2. Wear safety glasses and gloves for protection.
3. Loosen the lug nuts on the front or rear wheels (depending on which brake pads you are replacing) with a lug wrench.

2. Lift the Vehicle

Sub-steps:
1. Use a jack to lift the vehicle and place it securely on jack stands.
2. Remove the lug nuts and take off the wheel.

3. Remove Brake Caliper

Sub-steps:
1. Locate the caliper mounting bolts and remove them using a socket set.
2. Carefully slide the caliper off the rotor. Do not let it hang by the brake line; use a bungee cord or similar to secure it.
3. Remove the old brake pads from the caliper bracket.

4. Inspect and Prepare Components

Sub-steps:
1. Inspect the brake rotor for wear; replace if necessary.
2. Clean the caliper and bracket with brake cleaner to remove dust and debris.
3. Apply a thin layer of brake grease to the caliper sliders and the backing of the new brake pads.

5. Install New Brake Pads

Sub-steps:
1. Position the new brake pads into the caliper bracket.
2. Use a C-clamp or brake caliper tool to compress the caliper piston back into the caliper housing.
3. Reattach the caliper over the new brake pads and align it with the mounting holes.

6. Reassemble and Lower Vehicle

Sub-steps:
1. Tighten the caliper mounting bolts to the manufacturer's specified torque (typically around 30 Nm, check specific values).
2. Reinstall the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and then tighten the lug nuts in a star pattern to the specified torque (usually around 120 Nm).

7. Final Checks

Sub-steps:
1. Pump the brake pedal a few times to ensure proper brake pad seating.
2. Check the brake fluid level and top up if necessary.
3. Perform a test drive to ensure proper brake function.
