Hi, i am going to fit a remote servo to my sprint as i need to create more space for a decent airbox with my redtop c20xe conversion.
Looking around there seems to be 3 options on servo remote ratios
1.65:1
1.9:1
3.0:1
What was the original servo ratio for a sprint?
My brakes are uprated front sierra discs/calipers plus disc conversion to rear using cosworth calipers and fiesta mk3 front discs. They are absolutely amazing and hence i want to keep the same ratio for the remote set up.
Thanks
Ian

Re: Sprint brake servo ratio
I believe it was 3:1.

Re: Sprint brake servo ratio
Ok, thanks for the quick response. It does feel well assisted compared to non servo!

Re: Sprint brake servo ratio
I have all the bits here for a non servo'd Toledo, bulkhead adaptor plate, master cylinder (single circuit) and the long stiffener plate to connect to strut housing. Dont have a remote servo but MGB Hive do one for (guess what) an MGB for sensible money. I think the advantage is only 1.75 though. Good enough for a lightish car in my experience. If you can find one, a Hillman Hunter servo is good (2.25/1 IIRC) I have also used one from a Fiat 127 in the past but I expect they are like hens teeth now. Don't be tempted by a used Girling one, they are better than Lockheed in almost every way but repair kits are ridiculously expensive and/or complete unobtanium depending on model.

Re: Sprint brake servo ratio
My Rover P6 also has a pretty decent remote servo and its driven off a 7/8 girling master that would fit
the dolly bulkhead.

Re: Sprint brake servo ratio
Thanks for all the comments. I will probably either fit the sprint master cylinder to the bulkhead using a chopped up servo as the mounting bracket or fit the toledo master with correct mounting plate. Remote servo will be fitted in the boot and wiil be a 3:1 ratio one, new off fleebay. I have no room in the engine bay!
