I currently have three cars that need brake mods for a couple different reasons. The first reason is the Dutton has one of them early escort servos on a long bracket along the drivers side inner wing, and it is completly in the way of my dizzle conversion :/ Other reason is they are all single circuit and I would like to convert to dual circuit. I know you can remove the servo and the pedal is harder but brakes still work as good. But how much harder is the pedal? If I turn off the engine the pedal is really hard but is that the servo working against you or is that how hard the pedal will be? Also does anyone know of a good dual circuit cylinder that would be fairly universal and would be available with various piston sizes as I have drums all round on the Rebel, discs and drums on the Dutton and the Rumph has rear drums with big 4 pots up front. thankyou

Its hard to say how hard it will be as it kind of depends on what diameter cylinders you use, as well as the amout of pedal leverage. Calipers and pad type will make a difference as well.
Personally in a Dutton i wouldnt be worried about not having one, its light enough you wont need massive brakes, you can get remote servos if you really feel the need.
i used to run fast 1600 escorts without servos with no trouble, I'm quite lanky and usd to be a lot beefier but more normal mates were running them without with no trouble, it was more a luxury than a necessity unless you were really driving hard.

my vw bus doesn't have a servo and it is quite heavy disconnect the servo and go for a drive and see the difference. I once drove a Volvo 244 for about 11 thousand miles around australia with a broken servo, and eventually you get used to it

My desoto weighs just under 3 ton, has drum brakes and no servo.
You do have to push quite hard, sometimes two feet on the peddle and lifting ya bum off the seat helps, also shouting "stop, for Fu*ks sake STOP" also helps quite a bit ;D lol
But, tbh, it stops alright, you soon get used to it.

Just found a pic of my last Escort by accident, no servo.

I quite like non-servo brakes as you can really feel whats going on.
But in a soft cruiser of a car I'd have a servo for the ease of use.

Elise had no servo until the later ABS versions.
You get used to it very quickly, but beware when you get back into a servo'd car... you tend to stop faster than expected!!

I'd only say against it, if the car weighs more than 1500kg. Took the servo off my old scimitar, still stopped fine, just took a bit more effort.
Also, just removing the vac feed to the servo, will actually give a ridiculously hard pedal! You'd be better-off just using your feet against the tyres to slow yourself ;D
Try to see if there's anyone local to you who's got a non-servo car, and see how you get on with it.

Hi alan, My escort has no servo and as you've done me a massive favour the least i can do is return it!
As soon as it's back on the road it'll be the best comparison to the dutton.
I also have a remote servo that is curently unused that you could experiment with?
Cheers
Rich

I expect a lightweight car like a Dutton will be OK without - the same as my 1972 Austin Sprite. I do, however have a brand new servo kit ready to fit as I prefer brake to stop me with the least effort and if that means having a servo then "so be it". A servo doesen't improve the braking - just reduces the effort required to press the pedal. As others say simply try blocking the vac pipe to see what it's like to drive without servo assistance and unless you experience it yourself you won't have your own opinion. Dual circuits are useful for "peace of mind" but if you have a hydraulic circuit in good condition (perfect master and wheel cylinder, pipes and flexi's) then single circuit are just as good. Dual circuit remote servo's are very expensive whereas single circuit are quite reasonable new with plenty of good secondhand available that can be reconditioned.

I'd go for the non-servo option. The Dutton is light, and if you use the right size master cylinder (Mk2 Escort would peobably do the job), you shouldn't need one, Anyway, if you're going diesel, then a servo won't work, you need a power booster pump from a diesel car.
