Did all P6B's have vacuum assisted brakes?

Hi Rob,

Yes. Dual line brakes were certainly on the North American models (NADA) and quite possibly for models exported to some European countries. Not sure about those exported to the Middle East and Japan, but at a guess I dare say they likely had them too.

I am sure I recall seeing a Rover locally (think it was 4 pot) with twin boosters. Not sure what sort of brake design that one would have had. Harvey will certainly know!

I did a clutch on a 2200TC with that twin servo system dual line set up. That one was LHD. I think they were for export to Europe. Federal?

I don't know much about them TBH, I just used to open the bonnet and fix what was broken....

4 cyl cars have twin servos. V8s had a single servo on a dual circuit system similar to modern installation

None of my 4cyl P6s had dual circuit brakes. They do not get mentioned in my 4cyl parts book 606128.
More to the OP's question, every car I have had with disc brakes has had a booster. My V8 has a single booster on a single line system - only one outlet line on the booster.

Did your 4cyl P6s have twin boosters JP?

I don't know about the 4s but all the V8s that came to Australia officially were single line designs.

All US models had dual circuit brake systems after around 67-68 when legislation made it mandatory here. 66 and earlier were single circuit.

Ron,

No, my 4 cyls had single boosters, and single line circuits. And I would have known, I did lots of miles in them, and all the maintenance.
