What master cylinder would you use for this?

For now I'm using the std none servo master cylinder but once the rear disc brake conversion is done I will see how it goes and if needed I will buy a a better master cylinder and servo :)

Wow, no servo on discs, that must take a firm push to get anything happening.

It’s a good test of bulkhead integrity, for certain!

I am still bleeding my brakes (lockdown and remote garage so no access) so it will be interesting as I only have room for a short pedal tower and no servo on RRC brake MC. It may turnout to be too much as LR increased the pedal tower height for the brake pedal but I have to use a LHD clutch pedal for it as it is in a S1 with low bonnet. Actually it is the length of the dual MC that is too long to fit a tall brake tower without modification as it angles the MC down towards the S1 dashboard.

Can you fit a remote servo?

Yes I had one on the single line drum brakes and I have a pair that I was going to fit with the RRC twin cylinder twin line front calipers. Now I have fitted 90 front calipers I don't need twin lines to the front and don't want the rear through a servo particularly. Time will tell (once I can return to it) as if it is too hard I will add a the pair of servos. The Volvo 303 6x6 had them like that.

You can still use the RR master, blanking the unused port with one of those plugs that looks a lot like a solid bleed screw without a head.

I run a coiler NRC4772 servo on 4 x Heystee discs. Mine was undriveable without, and the reason is school-boy stuff,. Friction is a factor of force not area. Without a servo to make-up the force deficit now that the self-servo effect of the drums has been removed,  it can't be great. Got to give it to you, you've got balls. Force from the drums now removed, if it's an improvement, what state were the drums in!
