Remote Servo
chrisg - 19/8/05 at 05:29 PM

Now then.

I'm thinking of fitting a remote servo to my car, has anybody any idea what cars they were fitted to?

I've looked through my "Haynes" collection and I can only see the one fitted to 1275 minis which is a single circuit which is no good.

I've been told that SD1 rovers had a remote servo, is that right and if so, are they dual circuit?

Also, how do they work?

Brakes aren't my strong point, any help gratefully received

Cheers

Chris

Me and me mate were talking about these only the other day. They are fitted to older BMWs like the old Y reg type 3 series which i would imagine to be dual. Aint got a clue how they work though.

Some of the older Alfa Spyders had 2 remote servo's one for each curcuit. Why do you want a servo? seven type cars are very light and I suspect that servo assisted brake would be too much.. Only my opinion of course

Dual circuit you need two remote servos -- dual circuit ones are very rare only one that springs to mind is the E type but that was a really a single circuit form the master cylinder going to a dual circuit servo.

Most late 1960/early 1970s cars over about 1700cc such as the Hillman Hunter had a single circuit remote servo but there just isn't enough room under a Locost bonnet for two.

Remote servos were on sale at Harrogate Show. I know the single circuit Lockheed one was £168 because my mate has just fitted one to his new rally car. They also had a dual circuit one but I can't remember the price. Not entirely sure but think it was SVC that were selling them

Just checked on website and it was SVC £235 plus £10 p&p - http://www.s-v-c.co.uk/SVCOTHERP.HTM

Biggest problem with remote servo's is the standard failure mode. By this I mean that what normally happens is that they fail so that they suck all the brake fluid out of the master cylinder leaving you with no brakes and absolutely no warning of what is going to happen. (real scarry when its in a hunter and the handbrke lever is hidding between the drivers seat and the drivers door.)

Enjoy

Absolutely NOT!! The SD1 Rover had a Girling R80 (10" ) servo. This was the usual, direct-acting type, mounted as a mcyl+servo assy, on to a pedal-box, with b/pedal acting via a push-rod.

As britishtrident observed, remote dual servos are very rare, although I recall someone selling one for home-builders.
Thought it was S-V-C.

Lockheed servos are a better bet than the Girling type -- more reliable and much much easier to rebuild.

Get that pedal ratio altered Chris, or build some leg muscles.

Ah well you see thats the problem, although the brakes are pretty good now, they do need a hefty shove and because of my arthritis I'm finding it quite painful - it's the same reason my new car is an auto and that I've been looking for an auto Sierra to gut.

I'll have a look at SVC, I think I've got a catalogue somewhere but it's about £235 quid too dear for me.

Tight is my middle name

Had a look - whats the method of connection to the pedal?

Do you need a M/C on the pedal which is connected to the unit?

God I'm thick
