Braking question

[Vegard]

I'm changing the brakes on my 69 Pickup for drums to S brakes. Would I need a different brake valve for this? To be honest I've never checked if there is one present at all The car has just always worked.

What did the Cooper S have from the factory?

21A1774.
As fitted to all MK1/2 plus all Cooper S.
Hope this helps.

Thanks.
I guess it's already there. I've owned the car for 9 years, but I do not know this

Brake valve OK, but I'd suggest going to smaller rear wheel cylinders.

[Vegard]

Yup. I've already got a set of 1/2" ones. I needed these on my racecar as well. Less sideways action

Will get into trouble at "Biltilsynet" (Mot)?
I suspect that a -69 Pickup got a 250 lbs/in² reduction valve and 3/4" rear cylinders?

ps; is there any formula one drivers that do not left foot brake?

I don't know.. As long as there is next to no brakes on the rear, I'm happy
