Solution

1. Preparation

Gather necessary tools and parts.
Tools Required:
- Torque wrench
- Socket set
- Brake pad spreader tool
- Jack and jack stands
- Lug wrench
- Brake cleaner
- Safety glasses and gloves

2. Lift the Vehicle

Park the vehicle on a flat surface and engage the parking brake.
Use the lug wrench to loosen the lug nuts of the front or rear wheel (depending on which pads are being replaced).
Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheel completely.

3. Remove Old Brake Pads

Locate the brake caliper and remove the caliper bolts using the socket set.
Gently slide the caliper off the rotor and support it with a bungee cord or rope to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.

4. Inspect and Clean Components

Inspect the brake rotor for any signs of wear or damage; replace if necessary.
Clean the caliper bracket and rotor surface using brake cleaner to remove dust and debris.

5. Install New Brake Pads

Apply brake lubricant to the back of the new brake pads to prevent noise.
Install the new brake pads into the caliper bracket securely.
Reposition the caliper over the new brake pads and align it with the bracket.
Torque the caliper bolts to the manufacturer's specifications (typically around 25-30 Nm).

6. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove the jack.
Use the torque wrench to properly torque the lug nuts to the manufacturer's specifications (usually around 100 Nm).

7. Test the Brake System

Before driving, pump the brake pedal several times to ensure proper pad seating and brake fluid pressure.
Check the brake fluid level and top off if necessary.
