Brake Servo & MC relocation

Just reading through a few older posts, and this hasnt really been discussed as far as i can tell. (if so, sorry i missed it).

Reason for asking is the "bar" taking the brake pedal movement from Drivers-Passenger side where the servo is located must increase pedal travel, and brake feel, plus it looks messy, and its right in the way of where i want my new downpipe to go when i put this new turbo on.

First Ideas would be to get a hydraulic brake pedal, which would be linked to the servo and main MC. If you could do this then you'd be able to relocate the servo anywhere in theory.

Has anybody any thoughts on this, how other options would work? or even better done it themselves?? Open for discussion, it just interested me.

Julian relocated his to the driver's side, but I don't know whether he has registered on the new forum yet.

Redlee has a mk1 g60 with a relocated servo - done by previous owner and he is in your neck of the woods, chorley - so may be able to show you 'in the metal'.

email/pm him, he's got a lot on at any time and isn't on here very often.

Cheers sean, i've dropped him a PM.
Was having another think about this, another option would be to move the Servo & MC into the passenger footwell. you'd still have to use a bar to get the movemet accross but it gets it out of the engine bay.
Another idea anyway which i'm thinking about.

i think it was (very) old rovers that had a remote servo. i think this also became popular on rear engined stuff, to reduce the length of the vacuum pipe, and thereby increase the efficiency. never acutally seen one in the flesh to know how they work though. i'll see what i can find...

from what i can gather, you existing (!) brake mastercylinder that doesn't have a servo just pushes on a slave cylinder somewhere else that operates the servo and the "main" brake master cylinder attached to it. make sense? so you would use a non-servo m/c mounted on the pedal, and then have another one anywhere you can find the space

julian did his using 2 single outlet master cylinders and a balance bar mounted on box welded to the bulkhead and then ran all new brakepipes with 2 tees in
it is a lot like using an aftermarket pedalbox but all homemade
this type of setup doesn't use a servo alltho you could use a remote servo if you wanted
aparently they are very good but he hasn't let me drive it yet to find out for myself
you could try this or use a proper pedalbox
try rally design or demon tweeks have a look at the pedalboxes for a better idea of what they look like

That setup would be quite good Dave.. its definately an option, and propably easier to do than the other options. i have not looked to see how much space there is underneath where the pedals are, but I presume you'd be able to squeeze 2 MCs in there?
Nate, your idea is similar to what I wrote first right? but using 2MCs instead of a hydraulic pedal, 1 MC would be operated by the foot pedal, which would operate a 2nd MC linked to a servo? I take it thats what you meant?

Perhaps these guys could help.
They have an outlet near me and the guys are dead helpful.

From memory, I think Julian's master cylinders sat just inside the engine bay where the old pedal bar came through the bulkhead.

yeah they do he has them about 3 inches out bolted to 5mm plate steel with a standoff peice on each side to allow access from above and below to adjust the bias
you can buy a proper pedalbox that has the mcs facing backwards into the car (about £150 i think) i kno julian was gona modify his existing pedal to do this but its on the to do list that he adds to on a daily basis so may be a while away yet
i will try to remember to get him on here with a few pics to show what it looks like
