Plastic master cylinder is incorrect. They came in around 1970/1971 Sent from my SM-N960F using Tapatalk |

For a 67 model it would have had tin brake and clutch master cylinders originally |

Here is the engine bay for a 1967 S. If your car is pre YKG2S2 3792 it would have also been fitted with the plastic extensions. The brake master should be Lockheed .7" and have a tall reservoir. The clutch master should be a Lockheed .75" and have a shorter reservoir.

I had the same question today ! My 67 deluxe came with the same setup as yours , so obviously its been changed out along the way too. My plastic tank is PBR and must be for the clutch ....cant remember which side I pulled it off ! This is what happens to the tin after 50 years   Sent from my iPad using Tapatalk |

I bought a new one recently, and found it was a slightly different shape to the older style ones. The old ones were parallel the whole way up, and the new one I bought was thinner above the thread. E.g.

My Mk2, 1969 car 940, had the tall plastic clutch master cylinder & the original Mk1 type tin brake master cylinder, which I believe was correct for the era? |

Many thanks for the Service Liasion Letter It makes reference to "... and spacers are used to obtain pedal height" Can anyone tell me where these spaces are located and what thickness they are. |

This suggests that my plastic reservoir replacement is inappropriate as my threads on the pedal box will be too short ... let me go measure them. Didn’t know there were 2 types of pedal boxes Sent from my iPhone using Tapatalk |

These 2 spacers came with a car I'm rebuilding. They are 1/16" or 1.6mm thick. Both master cylinders are the plastic reservoir type and spacers are placed between cylinder body and the pedal box mounting point. Have no idea if they are original. I'm sure an expert will set this straight. I also have a car with a metal brake master and a plastic reservoir clutch master which has metal spacer. |
