I am renovating a Austin Healey 100/6 Bn4 I would like to fit a break servo bit it has to be original 1957 or before. The car is being prepared so that I can enter the Italian 1000 Miele race so every thing has to be original or as could have been fitted up until 1957. I would be happy to refurbish ,or one already refurbished, a unit and will consider any condition.

Yes I know but for 1000- Mile race you can have upgrades as long as they are age related. so the
keep the original front brake drums I was hoping to uprate the efficiency of the braking system. May be just to ambitious so I will stay with original setup.
Thanks for your reply though it was helpful.

I converted my 100 6 to disk brakes, it was a great improvement in braking power. I think it was an option available for the cars so would be period correct.

Early 3000 disc brakes (Girling) are a direct bolt on to a BN4. I believe the 100S disc brakes were Dunlop. And those are unobtainium.

I might have found my own answered to this? The BN1 seal is 2.3/4 inches for all other cars it states on the suppliers sites BN4 To BJ7 2,7/8 inch I measured mine and it is actually 2.3/4 inch so even though it a a BN4 car it still uses a BN1 Oil seal.
I know that the can was and early BN4 Longbridge built car, so may be this is the reason ?
