Stops Great. Could use a little more protection before packaging
Great Master Cylinder. Fast Shipping. Perfect for my hydroboost conversion setup.only problem IMO, is that they really need to oil better or clear coat these cast iron masters before packaging mine already had small amounts of rust on the exterior just from ambient air.A master cylinder isnt exactly something thats ideal to do any type of sanding or other prep work before painting.
