Solution

1. Preparation

Tools Required: Socket set, torque wrench, jack and jack stands, brake cleaner, C-clamp or brake caliper tool, safety glasses.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues.
Gather all tools and components needed for the replacement.

2. Lift the Vehicle

Loosen the lug nuts on the wheel before lifting.
Use a jack to raise the vehicle and secure it with jack stands.
Remove the wheel by fully unscrewing the lug nuts.

3. Remove Brake Caliper

Locate the caliper mounting bolts; remove them using a socket and ratchet.
Carefully 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. Prepare New Brake Pads

Inspect the caliper bracket for debris and clean it using brake cleaner.
If necessary, use a C-clamp or brake caliper tool to compress the caliper piston into the caliper housing.
Install the new brake pads into the caliper bracket, ensuring they are properly aligned.

5. Reinstall Brake Caliper

Carefully reposition the caliper over the new brake pads.
Tighten the caliper mounting bolts to the manufacturer's specified torque (typically around 30 Nm).
Reinstall the wheel and tighten the lug nuts in a crisscross pattern to ensure even distribution.

6. Lower Vehicle and Final Checks

Lower the vehicle off the jack stands using the jack.
Reconnect the battery.
Pump the brake pedal several times to ensure proper brake pad seating and restore brake pressure.
