BRAKE SERVO / MASTERCYLINDER; SORTED!
Discussion
Hi Richard
I think a new tread summarising all the above would be best, there is so much to-ing and fro-ing above it could well be confusing when someone has to go back to it in the future and the less clutter the better (I'm think of me 'cos when I'll need i'm not sure how many brain cells I will have left.)
Super job BTW, how do you find the time?
Thanks a bunch

Hi there,
Firstly thank you for the great help on this matter.
Just in case anyone wants to know as of 5th November 2011 you can still get the
new TRW original parts PSA 314 Servo and PMH237 from a website in Germany
called seekpart24.com .
My servo had rusted through and i bought them online. They were shipped and
delivered within 3 days and they fit straight into my S1 with no adjustments needed.
Thanks again for the help and i hope this helps anyone looking to buy a new replacement.

Early cars had Saab with remote reservoir later cars had the Fiesta unit with integrated reservoir.
Many have been converted to Fiesta as the Saab servo is hard to get.

Apart from others (S3C) that have the Fiesta servo + master cylinder with a Saab remote reservoir.Many have been converted to Fiesta as the Saab servo is hard to get.

Gotta love TVR!
Assuming they have stock, and they appear to have at the moment, the middle one will fit most S's and it will stop the need to mess about with second hand ones.
TVRParts are not quite right, there are actually 4 servo types and anybody fitting the middle one to a car which was originally fitted with a SAAB one will need the template to re-drill the bulkhead or it will be cocked over at an angle!.
£270.00 sounds a lot but that is a fair price now and looked after it should last 20+ years. Tell her it works out at less than £27 a year for brake safety.
I hope Glen sees this as he may recognise the first type, it appears to be the one fitted on 'Austin' which has puzzled us a bit. Must be only on a very limited number of early S1's. I stand to be corrected but I haven't seen it fitted on any '88 cars.

Thanks for the link!
Spent a few hours trying to find a SAAB or a Fiesta one :P
If I need a template, where would I find that

greymrj's post on 4 April 2008, further up this thread, explains exactly how to measure up a template.Alternatively, googling "TVR Servo Template" came up with this:

And a full step-by-step on changing the servo is here:

Do you want me to throw a cat amongst the pigeons? OK....
I went to Bristol ave last year, and spoke with the design engineer who worked on the S (and everything that followed it). He said no SAAB servos were ever used on the S-Series. They were all Ford types, just differing in spec slightly.
So....yeah. Enjoy

I doubt if the design guy had any idea what TVR were doing on the shop floor!!I went to Bristol ave last year, and spoke with the design engineer who worked on the S (and everything that followed it).

When we looked into this some years ago we were helped by a member of TRW staff and we were able to borrow copies of the relevant servos and check the casing dimensions and numbers. The so called SAAB servo numbers exactly matched the ones on several S cars, including as it happens mine. I had also just bought a new SAAB one for my car which again matched perfectly. The TRW records (which subsumed all the Lucas records) did not show a servo supplied to Ford which matched exactly. Believe me we went through the microfiche! They did show a servo which matched in most details (PSA328) but differed in location details, to that which has been supplied to Ford, and that showed up as having been supplied to SAAB only.
I doubt very much however if ANY servos were supplied to TVR directly as 'SAAB' servos, they were supplied (probably in this case via General Traffic as factor) as Lucas servos and perhaps a batch were supplied with the different location hole arrangement by mistake. Looking at the template you will see the differences are minor and one could easily have been supplied instead of the other. I assume someone at TVR just turned their drilling template round as it was a hand drilled job. There is probably a car out there with the original drilling then another set when the fitter found the servo was 45 degrees out, and another when the PSA328 arrived and the fitted found that was 45 degrees out the other way!
I did confirm that the servo would have been supplied complete with master cylinder.
It was only much later when servos were coming to need replacement when it was found the PSA328 was NOT correct, so the design guy probably had no idea it wasn't the expected Ford servo.
A good way to double check is to try to fit the Ford master cylinder to the 'SAAB' type servo!
When we came to try to sort this out it appears that there were two batches of the 'SAAB' type at different times, so while it was initially seen as a problem for S1 and a few early S2, a few later cars have proved to have the 'SAAB' set up. Either that or TVR stockholding was errrr....random?

The 'design guy' was Trevor Cooper - the design engineer. If something mechanical needed to be fitted, he was one of the guys tasked with making it fit. That said, he may not be aware that the (whatever the part no.) TRW servo was actually a SAAB unit. Doesn't sound like TVR actually knew it was a SAAB one, only the part no.
Oddly, my S1 had a Ford servo fitted, and none of the holes had been redrilled. They have now, because I've fitted one of the later ones.
