Solution

1. Preparation

Tools Required: Wheel chock, jack, jack stands, lug wrench, socket set, torque wrench.
Sub-steps:
1. Park the vehicle on a flat surface and engage the parking brake.
2. Place wheel chocks behind the rear wheels for safety.
3. Loosen the lug nuts on the front wheels (do not remove them yet).

2. Raise the Vehicle

Sub-steps:
1. Use a jack to lift the front of the vehicle.
2. Place jack stands under the vehicle to securely support it.
3. Remove the front wheels by fully unscrewing the lug nuts.

3. Remove the Brake Caliper

Tools Required: Socket set, caliper hanger or bungee cord.
Sub-steps:
1. Remove the bolts securing the brake caliper using a socket wrench.
2. Carefully slide the caliper off the brake rotor.
3. Support the caliper using a caliper hanger or bungee cord to avoid stretching the brake line.

4. Replace the Brake Pads

Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Clean the caliper bracket and inspect for any damage.
3. Apply a thin layer of brake grease to the backing of the new pads to prevent noise.
4. Install the new brake pads into the caliper bracket.

5. Reinstall the Brake Caliper

Sub-steps:
1. Compress the brake caliper piston using a caliper tool to allow the caliper to fit over the new pads.
2. Position the caliper over the new pads and align the mounting holes.
3. Reinstall and torque the caliper bolts to the manufacturer’s specifications (typically around 30 Nm).

6. Reassemble and Test

Sub-steps:
1. Reinstall the front wheels and hand-tighten the lug nuts.
2. Lower the vehicle and remove the jack stands.
3. Torque the lug nuts to the manufacturer’s specifications (typically around 120 Nm).
4. Pump the brake pedal a few times to ensure proper brake pad seating.
