Hi, wondered if anyone can help?
I'm just changing my front brake hoses (PO fitted two that only attached correctly at on end) and wanted to confirm what callipers these are?  Is it an original 914 - 4 front calliper?? Thanks Nick |

Looks like an early front caliper to me.

Okay, got some guidance from an expert : it's a 1967-69 911/912 M-Caliper.
Thanks all for your input! |

QUOTE(bdstone914 @ Jun 18 2020, 02:34 AM) Bruce, will have a look tomorrow, need to change the flex line on the drivers side! How hard is it to change the master cylinder - Eric suggested a 19mm might be a good move! |

The M calipers cover a wide variety of shapes and applications. That could well be a 911/912 caliper judging by the bolt & nut; appear to be 8mm. The 914 front calipers are from the VW 411/412.; they have 42mm pistons. The 911/912 have 48mm pistons. Other than that they are fairly similar but not identical. The ATE is important, but the letters & numbers are not.

Probably a wise decision to change ALL the flex hoses (IMG:style_emoticons/default/idea.gif)
