One for the thinkologist

The scenario:- series one, disc brakes, old fart
The solution:- brake servo
The problem:- getting a servo with the right feel, power,
balance, (read the mighty fuckwit essay on brakes)
Thinkology:- most pedal setups are to tall to fit under the
lower bonnet line of a series 1, single line servos are
available but still single line, so how about this
Get the right servo and dual line servo as put forward by
fuckwit, get a matching brake master cylinder as the one fitted
to my land rover, bolt the second master cylinder to the pedal
side of the servo and plumb it to run from the pedal master
cylinder.
The result:- push on brake pedal this extends the second
master/slave which then acts on the servo, the servo then gives
the boost to the secondary brake circuit and hey presto everyone
in the world is safe and carries on living.
Over to you lot to call me gay, nuts, get a life, whatever, it's
just an idea.
P.s. Dave do you want to move it out of the tech section to
somewhere else?

^^^^ Me to. Sounds like a recipe for disaster. A remote servo is
the only option I would take, single line is fine all your brake
lines will be replaced wont they?.....

I agree with divie.
We used to put servoes off Vivas on single line minis 2000 years
ago , doddle.
Don't make it too complex, it ain't necessary. SH><.

Yep, remote servo is the way forward:

There are several on ebay, but watch the ratio - you don't want
a 2.3:1 servo as it would be too sensitive - anyone who drove a
Citroen BX or Xantia will know what on-off brakes are like!

/>would do the job.
Cheers,
Robin.

Sorry if I've not made myself clear.
The effect I was after was to use a suitable modern servo with
dual lines but to fit this remote from the pedal box.
The best way of doing this I thought was to fit a hydraulic
cylinder to the side that would normally be operated on by the
pedal, that way the servo could be mounted in a position more
suitable for its size.

remote servos can be mounted just about anywhere you want to
mount them
i also think you're over complicating the job with this talk of
"hydraulic cylinder to the side", maybe you need to do a drawing
to help me envisage your idea

A bit like air over hydraulic on a lorry? Where a air valve on
the pedal opperates the master cylinder mounted down on the
chassis somewhere?

When Zeus first made and tested their disc brake conversion kit,
it was on a non-servo motor. If you go onto their website, it
still states that they are perfectly usable and safe without a
servo. Or at least it did the last time that I looked!

This was what I was getting at, sorry for the crap sketch, ipad

1, current pedal and master cylinder
2, second cylinder reversed and bolted to
3, servo'd dual brake line master cylinder
S.O.T.D. I've been running these brakes fine for a few years,
it's just an ankle problem that makes frequent stop start trips
uncomfortable, and was just after a servo to reduce the effort
put in, and not as most people think "improve" the brakes.
Most likely going with a single line remote servo, not sure
which boost ratio yet, still sifting though conflicting info at
the mo.
