A disc brake is the best present you can give to your Vespa suspension. And if you convert it to a fully hydrostatic system you're in brake heaven. The pressure point is very exact, operation is very easy, the power transmission is perfect. We offer different master brake cylinders from GRIMECA. The very high quality MBCs also have a very good price / performance ratio. We stock different pressure pistons. The pressure piston should be at least Ø 11mm and at a maximum, Ø 13mm. The Ø 11mm is very small and unobtrusive. The PX`98 version is attached to the PX`98 steering wheel or a corresponding attachment, the others are attached to the throttle tube. The steering column has to be modified on all Vespa models apart from the PX'98/'MY/'11.
