master is 7/8th....might be getting a 15/16th one soon if that ones not up to the task

camber plates are that way as i had enough camber and not enough castor.....so now i have more of both

OK, so it is a B310 booster. In a B110.

Now you have opened a lot of questions. What brakes does the car have?
Which master cylinder is it?
Does it bolt right in or did you have do any modifying?

Quote:1200s with stock disc brakes should have a "hard pedal" (firm and tight, not a lot of travel), but it shouldn't take much strength to push the pedal (pedal effort). What kind of problem did you have and did the booster make a difference?

yeah b310 in b110

car had landcruiser 4 piston front calipers and camry vented discs with r31 skyline rear discs and caliper

and now it has...or will have rather soon
all the brakes off a r32 gtr with discs machined down in diameter till they fit in TRX rims

master is a 7/8th 240k unit

had to make up a spacer/adaptor to go between the firewall and the booster and also had to enlarge the hole that the brake pedal shaft goes through
there is a pic here of the adaptor i made

so not at all stock brakes, pedal was very hard and after first applying the brakes it was hard to push them in further if i wanted to stop a bit quicker, was ok if i knew how hard i wanted to push them and did it in one go

havnt been able to test it yet as im waiting on brake lines for the rears
may still have to get a 15/16th master for a better pedal feel

unrelated question, but why are your camber plates diagonally mounted
