Brake Servo

Any advice on where is the best place to fit a brake servo

Not sure if this thread will be useful but there are a couple of suggestions as to where to fit one, although most of the posts are from people saying don't bother!:

If retaining drums , don't fit one. If discs then it will be perfect even for a wee little car like the Minor.
Fit the servo onto the engine bay tie plate and on the opposite side to the exhaust. Follow the instructions as to mounting angles and you cannot really go wrong. Remember to servo all 4 wheels , so the routing of pipework will need to be changed.

fit wolseley front drims straight forward fit bolt for bolt nut for nut gives super brakes no modifications to do...grandad

I fitted a servo before doing the work to ensure that the brake cylinders and the master cylinder were in good order. I then took it off because it looked so bad under the bonnet. The brakes work efficiently enough for me.
I saw a this http://www.youtube.com/watch?v=26s4R38fZGU and if you look at the shots of the interior, he has put the servo under the rear seat. A novel idea i like.(cant vouch as to wether it would work) You could consider this position if you decide you need servo.

//// helllo when i ask about a servo i was told only reduces foot pressure and dosent improve brakes /over to o knolegable one north of the border..grandad

The servo does only reduce the amount of foot pressure, which is the whole point of fitting it, when using discs. Some folk like the feel of a hard to press pedal, but others like me prefer a lighter touch and perceivably more subtle braking.
The servo in the box section under the seat should work fine, however I prefer to keep mechanicals out of the cabin, so, if using a different location to the engine bay, it would be sited in the boot under the loadbay.

Disc brakes have no 'self-servo' action and so yes, for discs, a servo will likely be needed = more expense and more hassle to fit etc etc..
Rally Minis etc often had the servo mounted in rear - under back seat etc - so there will be no problem doing that if you want to keep the engine bay clear. Considerable pipework required though!

i have driven a minor with discs and a servo and just discs and i can say without any doubt the servo makes it much easier to stop.
cant comment on with drums

Oh yes - if you have discs you will probably want a servo - all adds to the complication, and expense !

Only had the new Traveller for just less than 2 weeks and already my wife has applied for joint custody preferring her (the Minor) to the Italian rocket-ship she presently drives and herin lies the problem. Disc brakes and quite high pedal pressure. I've bought a proprietory kit from a Minor specalist which doesn't seem too complicated to fit - my problem was just where was best as although there is a lot of room under the bonnet the servo is quite large
Thanks for all the info on both threads

Slight complication is that you need to re-pipe the rear brakes through the servo - as standard they are fed from the rear of the master cylinder. That needs to be plugged - and a feed pipe run forwards to the connection point you will install after the servo. The low-mounted master cylinder means that you should mount the servo as low as possible - to minimise risk of air locks in the pipework that is above the master cylinder. You also need a vacuum feed from the inlet manifold. If it doesn't have a handy plugged hole - you will need to drill and tap one. Take great care to ensure no 'metal shards' escape into the inlet manifold !!!!!'

Would I be better to remove the inlet manifold for tapping just in case or is there an easy way

You can try smearing the drill and tap with grease - and wiping it off/re-greasing regularly!
