Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing Tandem Brake Master Cylinder

I'm trying to find a dual circuit (tandem) brake master cylinder to replace the single-circuit stock unit on the +4.

I just received the "upgraded tandem" unit from Morgan Spares. It looks wonderful, but will not clear my gear reduction starter. This wouldn't be an issue if the car was LHD which it looks like the kit MS sells is geared for.

I have ordered a Subaru BRAT/Brumby/Shifter MC, but am worried I may also have clearance issues against the starter. Wanted to know if anyone could confirm this would fit. The main difference between the MS unit and the Subaru one is that the MS outlets are on the left side of the MC body, angled right at the starter, whereas the Subaru outlets are straight down, with bleed screws angled towards the starter.

I did find one other master cylinder from Wilwood that has the outlets angled down, and the bleed screws to the right, away from the starter. The only problem is that it's a 1" bore instead of the OEM 3/4". I went ahead and ordered this too to maybe play around with. My pedal is already stiff enough though.

Any Ideas?

If you really get stuck for space might be worth having a look at these, I believe much smaller than a standard starter motor http://www.autoelectricsupplies.co.uk/category/138

How about two single circuit master cylinders with a balance bar.

Think that there is a kit available in the UK (mulfab I think)

Malcolm, I was also thinking about that too. I'll see how the ones I ordered fit but may go two singles. I have a few contacts at PFC (Not sure if y'all have that company on your side of the pond) that could probably help me out too.

I certainly intend to go the two cylinder route on my +4, I converted my TR4 in a similar way some time ago and it has worked very well as well as being 'period'.

If the link works, here is the Mulfab solution
