c'mon nick of course you need a booster with your brakes! when your 1200 suffers elephantitis of the brakes it
suddenly isnt light enough to warrant not running one!

ok, as for the hot engine with twin carbys not being able to make a booster work...thats bullshit

when i had the landcruiser 4 spots and r31 rear with a 7/8th master i didnt have a booster on the car and that pedal feel would be fine for on the track when you sorta know when you want to brake and stuff like that. but if you were starting to pull up on the street and for some reason had to stop alot quicker it was pretty hard to get the required force in the time you had

then i went to the R32 4 spot front twin spot rears with an r33 15/16th master. i installed a booster then coz i wasnt really that happy to keep driving with the old pedal feel. took the car for a test drive then realised that the booster was dead. that was just scary, having massive brakes but still having to be pushing the pedal as hard as i physically could to get the thing to pull up like a stock 1200(the seat was flexing a fair bit i was pushing back on it so hard)
got a new booster on it and to say it was a completely different experience would be an understatement. with everything the same brakes wise and a working booster it pulled up better than anything else id ever driven
and that was with an L20b and twin 40s, then the really worked L18 with twin 45s, both of which allowed the booster to work fine
and even with the CA thats on boost almost all the time the booster still worked fine

its more a thing of how big you go with the master cylinder as to whether you need the booster or not, if your still using the stock master or anything close to the size of it of course your not going to need a booster
but anyone that thinks that boosters dont do anything and are just for people that are too weak to press the brake pedal hard enough...come have a drive of my car with the booster line disconnected

i run s13 discs on the front and dont have one, the damn thing near lifts the rear wheels off the ground if i brake hard enough ... i went to a brake shop here in adelaide and the guy wouldnt give up the "fact" that you have to run a booster as soon as you go discs

Unless you're a 90lbs weakling, they just aint needed. I run S13's on the front, and U13 discs on the rear. With a standard 1200 M/C. The pedal is just right, with lots of feel, and tons of control.

Yes, properly adjusted rear brakes with stock Datsun 1200 discs will have a very firm pedal feel. And do not take a lot of effort. The heavier cars (such as B210) can benefit from it, but the B110 is still light and friendly

I'll add my vote to the "why bother" side of the camp. There is just not a need for power brakes in a car as light as the 1200. I personally like the "squeezing a brick" feel of well setup un-boosted brakes. Better feel and control when braking at the limit.

My old rally car had B310 front disks and rear disks off of what was sold as the 200SX in the US. No lack of braking or high pedal pressure here...

Don't need em on 1000's

Never had one... never will

I actually dislike power brakes............in general they seem to lack feel............even the best of them seem to have a non linear feel, my 01 Protege ES is a prime example. For anyone who's driven a single seater they have a rock hard pedal, more force more braking vs. boosted brakes that seem to have more travel equate to more braking............as I said the first 1/2 of travel seems kinda gushy. Early 911's seem to have the right amount of effort.

Adding a booster is essential for looking modern and appearing to be better equipped than the next guy's car.

oh mine has strong vaccum.. nearly sucks my finger in the hose when i took it off to see if its suckin air
