Dual Circuit Master Cylinder for 4-Wheel Disc, Standard Type 1

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 standard Type 1 only.  Do not run this master cylinder if you have front disc brakes only.
