Checking Brake Pads

→ Only use the type-specific brake pads listed in the Porsche Parts Catalogue.

→ Replace the brake pads when the brake pad wear indicator light comes on, but no later than when there is a residual pad thickness of 2 mm on each axle.

→ Replace the brake discs on each axle as soon as the brake pad wear limit is reached.

→ Use two assembly pins when removing and fitting the wheel.

→ Carefully guide the wheel towards the wheel hub, thereby preventing any heavy impact on the (ceramic) brake disc.

Information 

• If brake pad wear is indicated by the warning light, the warning contact (sender including wire and plug connection) must also be replaced. 
• Replacing the warning contact can be avoided by replacing the brake pads no later than when the pad thickness is 2.5 mm -arrows-  .

• Warning contacts must be replaced if the core of the wire is worn. 
• However, if only the plastic part of the warning contact is worn, there is no need to replace it. 

Visually inspect the brake pads for wear.
