Product details
Connect the matching Wilwood D31 rear brake conversion to your Porsche’s brake lines with this 16-inch braided hose arrangement. Select it by the installed Wilwood kit number, not by vehicle model alone.
For the specified Wilwood calipers. This is a conversion hose and fitting arrangement; do not treat it as a direct replacement for an original-caliper hose kit.
Before ordering: Contact PMB to confirm the supplied adapters, hose connections and package count for your installed rear brake kit.
