Rene Herse Centerpull Bushing Tool
The Rene Herse Centerpull Bushing Tool allows for removal and installation of bushings in Compass and Mafac brakes. Simply insert the tool in the existing bushing and tap with a mallet to remove. To install, place the new bushing onto the tool, line up with the hole in the brake arm, and tap with a mallet until the bushing is flush with both sides of the brake arm. We use a soft piece of wood beneath the brake arms whenever inserting or removing bushings in order to protect the finish.
Since not all Mafac brakes were made with precisely the same size holes for bushings, we recommend reaming them out with a 10H7 reamer before installing Rene Herse bushings.
