Im no expert, but I can share what I know.
I was looking to upgrade my 72 super's MC. Turns out it's a 19mm MC, which is an UPGRADE for 914's (17mm i think). So, I just went with a new german stock 19mm MC. That's what I know.

I think a 911 unit would work well in that application. Usually 914s "upgraded" to the 911 MC especially when putting on BMW 320i front calipers.

Are you saying that 320i calipers will work on the beetle stock disk/spindle? Martin PS:I've just started a new topic about calipers, you can post any info there. |

It really depends on whether the rears are floating cylinders or not. Basically a floating cylinder only has a cylinder on one side of the pad. A non floating cylinder has cylinders on both sides of the pad. A floating cylinder requires alot more fluid before it reaches the rotor. Therefore a larger diameter MC. Unfortunately the larger MC requires more petal pressure due to a less desirable mechanical advantage. A major reason most floating systems have vaccuum assist. With a dual pot front and a dual pot rear the stock dual circuit MC should work fine.
The 914 people use a 320i caliper on the front as an upgrade. It is susposed to bolt right up. I just don't know it the caliper bolt pattern is the same as the bug bolt pattern. Some one with both needs to clarify this once and for all. Hope this helps. |
