why does my Porsche Cayenne E3 (2018-Present) display show “check brake pads”

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and secure with wheel chocks.
• Disconnect the negative terminal of the battery for safety.

2. Lift the Vehicle

• Use a jack to lift the front or rear of the vehicle as necessary.
• Secure the vehicle on jack stands to ensure stability.

3. Remove the Wheel

• Use a lug wrench to loosen and remove the lug nuts.
• Take off the wheel to access the brake assembly.

4. Inspect and Replace Brake Pads

• Inspect: Check the thickness of the brake pads. If they are below the manufacturer's minimum thickness (usually around 3mm), they need to be replaced.
• Remove old pads: Unbolt the caliper using a socket set, support it with a hanger to avoid stress on the brake line, and remove the old brake pads.
• Install new pads: Position the new brake pads into the caliper bracket, ensuring they are correctly aligned.
• Reinstall caliper: Carefully push the caliper back over the new pads and secure it using the original bolts. Torque to manufacturer's specifications (typically around 25-35 Nm).

5. Reassemble

• Reinstall the wheel and hand-tighten the lug nuts.
• Lower the vehicle from the jack stands and remove the jack.

6. Final Checks

• Tighten the lug nuts to the specified torque (usually around 100-120 Nm).
• Reconnect the negative battery terminal.
• Reset the brake pad warning light if necessary, using the vehicle's onboard diagnostics.
