Brake master cylinder

I was unsure of the correct size of the Lockheed brake master cylinder for the JB Van, so I dropped into Darwin's Winnellie Brake Centre today on the off chance that they had a kit listed somewhere. Sure did! Old mate picked up the Lockheed stock catalogue, and flicked through a few pages to "Morris - JB".

The book showed that the master cylinder bore was 7/8", the same as the pre-1962 Morris Minor. In fact, a cross-check showed that the seals were identical, having the same individual stock numbers. The only difference was in the external rubber boot, the MM kit having a plain boot, and the JB kit having a "concertina" type boot. Tongue in cheek I asked him if he had a seal kit on the shelf, at which he smiled and produced a JB one, and said that he always carried one kit. The price was AU$24 which I thought was most reasonable. So I got my master cylinder seal kit, and he is going to get another in for me for the clutch. The only difference between the brake kit and the clutch kit is that the one-way valve is not used.

So, coming up shortly is a master cylinder re-kit for both brake and clutch, and for the clutch slave cylinder.

  1. Nice work Bugly! I think these are the same brake people who helped me. They had the JB on the books. Great service. they have helped me with my Sunbeam Alpine, 1968 Saab 96 and even with my NSU Ro80 - they have just about everything.
