Brake Caliper Adapter for Upgrading the Rear Axle of Golf 7, Audi A3 Series to Porsche Cayenne Calipers

This adapter allows the installation of Porsche Cayenne rear brake calipers on the rear axle of VW Golf 7, Audi A3, and related models. It is designed to be used in combination with Audi A6/A7 brake discs (356×22 mm).

The Porsche calipers are connected to the vehicle’s hydraulic system, enabling significant braking power. However, since these calipers do not have a handbrake function, the rear caliper from the VW Golf 7R is used separately as a parking brake. Its hydraulic connection is sealed with a blind plug, making it function solely as a handbrake caliper.
