My SII does not have a vacuum brake booster, and that's fine... actually I don't WANT one because when I convert to electric I would have to add an electric vacuum pump if I had a booster....
What I am wondering is what is the difference between the older boosterless master cyl, and newer vehicles that all seem to have boosters? Do the boosterless masters have slightly smaller bores to raise the psi without requiring too much more travel? Is it just that the boosterless design requires a little more pedal pressure to stop the same?
In part I want to know because I suspect my master cyl on the SII is getting to the point of needing a rebuild, and the current remote reservoir line looks somewhat cobbled up although it is not leaking yet, the reservoir is a little rusty and nasty. The reservoir is stuck on a bracket right on the firewall next to the brace, but the feed line has a couple kinky looking 90 degree bends I don't like the look of.
I am wondering if there is a particular model of Wilwood or some other 'performance' master that might yield better braking while remaining boosterless?
or, would I have to also add in something like dual piston calipers in the front to get better braking with the same pedal pressure?
