Dia. of US spec D90 brake servo?
I'm doing a little research on Defender brake servos.
Could someone please let me know the diameter of a US spec Defender brake servo, STC442, AKA STC4322. This would be for 1990 & newer non-ABS Defenders.
I have never seen the boost ratio numbers for Defender servos. Does anyone have those? In specific I'm looking for the ratio number for the above servo and those for the type 50 and type 80 servos. Both of these are for pre 1990 Defenders.
Thanks for your help
