Given that most people have the opposite problem with their series - ie not having enough brakes, I’m guessing you may be the first to do this. 😉
Can’t think why it wouldn’t work though, as long as you think your current braking is ok without it.
I have a need to remove the Brake booster from my Electric Series3
90% of my braking is done via regen braking and I simply don't need the Vacuum Booster or added complication of the noisy 12v vacuum pump . The service brakes are really only used to bring the car to a full stop or to hold it on a hill .
I never had an issue with stopping non boosted brakes on Series1 or 2A .
Installing a Series 2A non boosted Pedal box would be easy but I want to keep Dual Circuit brakes and I don't believe you can get a dual Master Cyl for a 2A , nor would a Series 3 MC fit a non boosted pedal box .
So I'm thinking of machining up an adaptor to bolt the Dual cct MC to the Series 3 pedal box to replace the vac booster. Then I can go ahead and remove the annoying vacuum pump.
Anyone done this before or bad idea ?

2 things will happen, maybe 3
1. you will develop a real talent for gearing and judging traffic and distance.
2. You will develop a right leg like a cent drivers left.
3. you will develop lighting fast foot co-ordination to get both feet on the brake pedal at the same time

Not sure, as its my EV Landy, Most of the braking is Regenerative , I only press the brake pedal down to actually come to a full stop .
I don't need to change gear to slow , The regen is powerful enough to lock the wheels if I screw it right up. As the car slows to under about 5kph the regen loses effect and thus need the brake to stop rolling.
However I understand if I need to stop on a steep low range hill , I'll need both feet on the pedal .
Im thinking if I go down a size in the Master cylinder at the expense of pedal travel , The friction material hardly gets any wear so wont need constant adjustment like an ICE powered Landy.
Hmm , wonder if these are ADR compliant

the only time the friction brakes are used here is to come to a stop in the carpark, the rest is regen braking only, notice no gear changing at all.
Tesla electric brake booster?

Just run a small elec vac pump and wire it up so it only.comes on when regen is happening.

I’m not sure I understand the problem. If you are not using the brakes then the vacuum pump should not be running.
I don't see why it wouldn't work. I roll down my driveway at about 5-10kmh with the car off and it pulls up to a stop without needing a great deal of pressure.
Pretty much the same thing you are doing. Could you just blank off the vacuum pipes?
I already have a Vacuum Pump, it runs when the vacuum drops below 18"Hg via the switch ate the bottom of the servo.
What I'm basically trying to acheive is to eliminate annoyances , The car is otherwise silent as I pull up to a stop I press the pedal down & the damn pump starts up . Brrr brrrr & people turn & look like I'm tooting a buzzer trying to attract attention , its just embarrassing .
Since most of my Braking is regen I thought why not just get rid of that annoyance all together,
I would gladly swap the Pedal box & booster for a Series 2A non boosted type , except they are only single circuit & I want to keep the dual circuit setup.
I am doing much like this with my 2B FC. There is no room under the short bonnet for the booster on the MC tower. I want dual circuit so I am bolting the dual MC direct to the tower then the twin pipes to the shuttle valve thing then to the VH40 boosters one to each axle. You could do this but leave out the boosters.
I just bought a short tandem master from the brake place on Friday.
I did this on the 6x6 I made into a FC years ago doing the same thing but using the big Ford MC bolted to the tower without the booster and using three remote boosters . Its been working for years.
