Hi

Lol First post but i htink its a good question i did a search but sisnt really come up with anything LoL.

Any way i have a disc break setup on my mini that im rebuilding and was wondering is it worth putting a break booster on. Would it make a great difference???

Thankyou

Depends on your driving style and personal preference

Are you fast and furious ... or.... laid back and just cruisin'

well im only 16 so it will be my first car so what ever is safest pretty much i guess ill be more so fast and furious LoL and it will be like a show car so yeah.....

Won't stop any quicker, it'll just take less pedal effort.
We have 2 Minis with S brakes and no booster on either.

K - so the booster thing is really just a choice of "feel" of the brake pedal - my research indicates that it does not do any "boosting to brake efficencies" at all. it does not make the brakes "better" but modifies the effort required by your leg on the pedal to effectively make the brakes do their thing.

So with booster you have - the further the pedal moves down the more the brakes come on and the quicker you stop - very much like a modern car. Plus = easier to work the bakes. minus = not much "feel"

And without a booster fitted - the more "pressure" you apply to the pedal the more the bakes come on [and the quicker you stop. Plus = you get to feel exactly how much braking effort is being applied. Minus = physically you need to do some work [but I think this is actually a plus because it means you actually have to drive the car]

So the choice is yours - do you want effortless braking that gives very little feedback or do you want to be the driver, the one in control of this vehicle.

For simplicity and "one less thing that can break down" factor
I would suggest staying unboosted

More room in engine bay too.
easier to set timing, that's if you still use the flywheel peephole (I don't).

This is very impotant in damp conditions - especially if you're inexperienced. Minis don't have anti-lock brakes so the more feel and feedback through the pedal the better.
Also - competition wise, most racing minis (using S-brakes) remove the booster for the same reason.
The pedal pressure is higher, but not deleterious.

After driving my 1275 LS (8.4" discs unboosted as standard) i'd say don't bother.

But... if you are used to a modern car, then it would be an option to be looked in to. After a while, however, you'll get used to unboosted brakes, anyways. Meh!
