Brake servo
Turbo Mini Forums

I have a brake servo sitting at home next to the car, i have the pipe and the diffrent brake pedal which seems to be needed to fit it all to my mini, but should i? I have metro turbo brakes on the front and standerd drums on the back got about 110bhp so its not hanging around. Some people seem to thing there wicked and i should fit it and some say theres no point. Lets opened it up. Servo or no servo?

Personally I have never run a servo in a mini,

I think you get more 'feel' through the pedal if you don't run one.

As for stopping power with turbo 4 pots you should be fine.

BTW - I took my buddy VTEC Pete out for a spin this weekend, and even though I am running her in, he gave it a name, the "Brocket"...cause I'm a brocket maaannn, nah nah nah nah nah nah nah nah nah nah nah....

Let's make sure you embarrass at least one VTEC MINI today !

For a road car yes. The feel isn't much different as far as I can tell and it takes much less effort on the pedal.

For a racer it's a lot of weight to carry around so I wouldn't bother.

Bin it!


I ripped mine out as it was robbing a mahoosive amount of space in the engine bay.

The only difference it gives is a firmer pedal with about half the pedal travel, it doenst improve breaking efficiency. Its purely a 'feel' thing. Personaly its a waste of space just for a different feel.

are you sure you have turbo brakes? not just late metro brakes?

any way i have the rover cooper servo in my van and have had the vented discs, and the servo makes the pedal lighter and gives more confidence in the brakes.

you dont need a servo, it just makes it more civilised (spelling?)

Seems even so far 2 for and 2 against. At the moment i can spare the engine bayspace. The car will do the odd track day and nice summer driving as i have a Mx5 for winter times (hardtop stays on all year) but the extra waight won't make to much odds. but if all it will do is make the peddel lighter there not much point, i want to improve brakeing not just make it easier.

I have a break servo in both my minis and think they're great :)

try without a servo, then when you get pissed off with crap brakes you can fit the servo. it wont make the braking any better BUT atleast when you press them hard compaired to modern cars they will slow you down.

with out the servo, and compared to modern cars you will need to stamp the pedal and try and rip the stearing wheel of the car just to try and slow a bit.

thats a good argument for. No i don't use the mini every day i have become weak and pittiful and i bet once i get back in the car i will remmeber how heavy the wheel is and how hard the clutch feels and the momentus power needed to stop the blasted thing. the Mx5 at least doesn't have powersteering but think my legs mite get a shock driving the mini again. Thanks

I personaly dont think that it makes the pedal lighter

It makes the feel of the pedal hard and there is less travel.

So less travel means more effort, the extra effort is privided by the servo. You still apply the same effort to the pedal the brake efficiency is still the same but there is less pedal travel.

the whole point of a servo is to add more pressure to what you put on t the brake pedal, so less effort is needed by you to make your car stop

good point, but the pedal travels less. Your satement does not explain this

servo works perfectly, but it's a enormous peace off metal unter the bonnet. i binning mine soon.
so : no servo

there is nothing wrong with a A-series that a turbo can't fix.

I replaced the standard tandem brake master cylinder for a later type pedal box servo and TBH I was a little dissapointed with the servo. Main reason for the change was to get a lighter pedal, since using 7.5inch S discs with 4 pot calipers resulting with a very hard pedal resulting in leg ache after a days driving. Personally I wouldnt bother fitting it. Now I cant be arsed to swop it all back, however if your like me you proabably like finding out for yourself!

lol. yep, i need somthing to do and i have 3 days at the end of april to get the car out the garage and in to fighting roadgoing status. so i'll do it then.

Nice one! Gunsons Easybleed to the ready!

as i dont have a servo/pedal box to look at i would guess that the leverage points have changed, so less pedal movement is needed to exert the same amount of force, master cylinders a different maybe

yep easy bleed is standing by and i think i mite push the boat out and use dot 5.1.

alrighty!

I thought the turbo ones were 4 pots with vented discs. the later ones didn't have the vented disc so need a spacer to fit them discs.

waste of your 3 days i'd say...

turbo brakes and late metro brakes are the same. it just gets me that people sell them as "turbo Brakes" when there actually off a 998 metro city. like people sell "genuine turbo cam shaft" rather than put standard 1275 cam. after all, if say 1 million metros came with vented discs and say 5,000 were metro turbos, then shorly they should be called standard metro brakes and not try and claim there something special

I agree

But hey, anything to boost the money on ebay hey?!

When I built my NA Mini I started with a Racing Green which had a servo as standard so I kept it.

My Turbo car (soon to be back with us ... hopefully) it uses a front / rear tandem split master cylinder and it has far more pedal feel, more confidence inspiring and most important more progressive.

With Mety 4pots on the front you have enough power to lock the wheels at almost any condition ...... it's all about pad choice to get the feel from there.

This is the reason I will not, under any circumstances, fit Minitex pads to my cars!!!!!! They don't bite from cold anywhere near as well as standard Ferrodo road pads, seem to fade before the Ferrodo's on the track and also seem to suffer in poor road conditions but that is probably a combination of lack of initial bite followed by a sudden improvement in performance ... result a blocked brake!!!

For a road car you can't beat Ferrodo road pads (yes the ones any motor factor, HellFrauds included, sell over the counter) and if it's a track car I'd always fit EBC pads as I have never had them fade on any vehicle!

Every day is a school day ...........

How fast and how expensive ...... the same question...
