Checking Thickness Of 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 upon reaching the wear limits.

Information

• Replacement of the warning contact can be avoided by replacing the brake pads no later than when the pad thickness is 2.5 mm -arrow-  .

• Warning contacts must be replaced if the core of the line 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.
