Solution

1. Preparation

Tools Required:
- Socket set
- Torque wrench
- C-clamp or brake caliper tool
- Brake cleaner
- Clean rags
- Jack and jack stands
- Lug wrench
Parts Required:
- New brake pads (specific to Porsche Cayenne E3)
- Brake grease (for caliper pins and backing plates)
Safety Warnings:
- Ensure the vehicle is on a flat surface and securely supported by jack stands.
- Wear safety glasses and gloves to protect from debris and chemicals.

2. Remove Wheel

Loosen lug nuts on the wheel where brake pads will be replaced.
Lift the vehicle using a jack and securely support it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Brake Caliper

Locate the caliper mounting bolts and remove them using a socket.
Carefully slide the caliper off the rotor. Do not strain the brake line; support it with a bungee cord or similar device.
Remove the old brake pads from the caliper bracket.

4. Compress Caliper Piston

Use a C-clamp or brake caliper tool to gently push the caliper piston back into the caliper housing. This will create space for the new, thicker brake pads.
Ensure the brake fluid reservoir cap is loosened to allow fluid to return without pressure buildup.

5. Install New Brake Pads

Apply a thin layer of brake grease to the backing plates of the new brake pads to reduce noise and ensure smooth operation.
Place the new brake pads into the caliper bracket where the old ones were removed.

6. Reinstall Caliper and Wheel

Reposition the caliper over the new brake pads and align it with the mounting brackets.
Secure the caliper by tightening the mounting bolts to the manufacturer's specified torque (typically around 30 Nm, but refer to service manual for exact value).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to the specified torque (usually around 120 Nm).

7. Final Checks

Pump the brake pedal several times to seat the new brake pads against the rotor.
Check the brake fluid level in the reservoir and top off if necessary.
Test the brakes at low speed to ensure proper function before driving normally.
