Mick.
I sat the larger one where they usually sit in my 850. There's not enough room between the engine and where it should sit?
Took a couple pics.

| Post subject: | Brake booster rubber diaphram |
Greetings All. The brake booster I have is missing the rubber diaphram. It's a Mk1 vh44 It has a PBR 260550 slave cylinder. Where can I source a new diaphram? Is there a part number I can google? I have a Mk2 booster which is the same hydraulics, but with a larger diaphram (Protex 40-10) Is there a parts site or list somewhere I can use? Cheers Alex |

Very easy to get. Hoppers Stoppers will have them, but they're just one name of thousands of suppliers however.\ Great website however. Its like wiki for brakes. http://www.hoppers.com.au/ |

VH44's were on mk2 mini's and GT's. mk1's had Lockheed ones. Unless there are two types of VH44Ja boosters (but im 98% sure there isn't) I think the diaphragm went in mine too, so good thing to know where I can get em. Cheers Mick |

Mick. Just went out and had another look. They both have PBR 260550 slave cylinders. They are exactly the same. Under the little filter grill, they both have VH44-4 in the casting. The steel chambers both have PBR stamped on them. The only difference is that one is 7&3/4 inches and has a diaphram rubber (Protex 40-10) The smaller one is 6&1/4 inches and missing its rubber diaphram. Nothing has Lockheed on it? Cheers Alex. |

Your larger 7.75" unit is your VH44 (7.5" Diaphragm). This is the one to rebuild. I'm not sure of the other smaller unit. VH40 units are larger at 9" |

The measurements tell me different, but I may be wrong. The larger one is a VH40 with the smaller unit being the VH44. Similar in construction, but the larger unit brings more pressure to bear on the brakes. Too much perhaps for a mini, hence the 44's are the ones we usually use. |

Doesn't the bigger one belong in the Landcrab? |

Yes. That's where I started, then wondered off. The larger one was out a 1800 at the wreckers (why?) becuase it was there. I then thought it was possibly Mk2 and the small one Cooper. Anyhow, I'm going to clean up the small one and visit a place in Adelaide called Power Brakes. I've been to I need a VH44-38 diaphram rubber. The slave cylinder on the larger one is in perfect condition. I'll check the cups and use that with the smaller chamber. Cheers all. Alex. |
