When running disc brakes on all four wheels, you'll need a larger master cylinder to supply the proper pressure and brake bias.  This master cylinder is designed specifically for that purpose.  You'll also need to run a residual pressure valve inline with the rear brake supply tubing, so be sure to order one of those, too!  Fits Super Beetle only.  Do not run this master cylinder if you have front disc brakes only.
