Beetles have 40 mm pistons, while type 3s & 4s (and 914/4s) have 42 mm pistons, so the beetle seal rings will be a bit small. They may work, however. Early type 4 (and 914) calipers are the same as late type 3 calipers. Late type 4 (and 914) calipers are different and take a distinctively different rebuild kit.

I've done this, too, but in the end it's easier to just pump the pedal. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
