removing brake booster ?
Discussion
WATCH OUT!!
in the new computerised MOT system there is a check for the "presence and security" of the brake booster if the car was originally fitted with one. remove it, and your car will fail....
My local MOT place failed my rally car due to this, even though the car originaly had 180mm non vented front discs and rear drums, and now has £10k's worth of AP stoppers (380mm 6 pot fronts, 330mm 4pot rears + AP floor hinged pedal box).
Fortunately i argued with the tester and a quick road test demonstrated that there was not a lot wrong with the new brake system, even without the servo.........
(in fact, due to the 10" wide hot slicks + AP's finest, he is now slightly blind as his eyeballs popped outta his head when i hit the middle pedal at 60mph!!! lol)

It reduces pedal pressure. It doesn't actually increase the effectiveness of the brakes, only the amount of effort needed from the driver.
Many modern cars are dramatically over-servoed, so that they don't tire out little old ladies in stop-start city traffic, and to fool those who equate light brakes with effective ones into thinking that the car ghas superior braking power.
As Snake says, if the car doesn't weigh much, you don't need a servo and, indeed, if one is fitted the brakes can be over-sensitive.
Also, the 'harder' pedal that you get on non-servo brakes can make it easier to modulate the braking and to heel-and-toe smoothly, if you want to drive really fast.
