Might fit if you're getting desperate.

Worth a punt for £15? Might have the correct bore and piston length and strike lucky.

I reckon that'll be 23.8mm bore, larger than the standard 22.2mm master cylinder?


So it will move more fluid for a given amount of travel, handy if you have bigger calipers (and bigger bore pistons) scratchchin


Downside is a reduction in mechanical advantage, but the servo could help compensate for that (servo ratio not known)?


................ or just "man up" and press harder wink

Scrap that mention of the m/cyl bore. Irrelevant if all you need is the servo.

Master cylinder looks very different, mounting flange may/may not be same dimensions ... scratchchin

If it's just master cylinder seals you need, I bought them from Bigg Red and fitted no problem, still listed on EBay, believe the unit is Girling and although the master cylinder outlets are different the seals are the same as the sierra.
please see image for purchase details
