[tattooinfiat]

ive heard thats the brake booster is unnessacary..true false? pros cons? mine is ugly and it really would clean up engine compartment..any thoutghts would be greatly appreciated...

I had my booster go out once. It was very difficult to stop. I don't know what would happen if you intentionally remove it.

Its just fine, lock's em up with no problem. I did get the EBC Yellowstuff pads for my car and they really make her grip harder than the cheap pads that were in the car when I bought it.

your sayin its fine to take it out then?

"Opinions vary". Braking force increases significantly. I've done a very crude measurement; looks like about 70-90lbs. Put a bathroom scale against the wall (on a stud!) and see for yourself

Yes, I said it is ok to remove it. Maybe if you have a bad knee or something its not a great idea, my very petite wife can lock the wheels up, you just have to be ready for it. You get great feedback without the booster and you can run the sidedraught carbs if you can find a manifold

haha knees are ok..if i remove it do i need to reroute any mc or lines what have you?

Remove the vaccuum line to your brake booster (which eliminates the boost) and go for a drive. It is not fun.

I was in a Jeep once that lost the booster. With both feet on the brake pedal, I still couldn't stop it. That's not normal, but it does take a lot of effort and gets old quickly in traffic or after a long day.

yea tried that didnt enjoy it much..it wasnt terrible but i liked it better with the booster..im jus trying to do something to clean up left side of engine compartment..on the right side all i have is a small over flow tank and a coil thats it.on the left brake boostrer..gobs of wires tubes and hoses..the charcoal canister(not sure if that is nessacry either) fuel filter and mechanical fuel pump..so on and so on..any suggestions on cleanin it up i see these pics of motors on here and they look clean and simple..mine looks like a teenagers messy room..haha if he were into fiats

Removing the vaccuum line from the booster did not accurately estimate the force to brake withthe booster actually removed, its a bit easier with the booster gone..,maybe my booster was on the outs though, i dont know how they work and have never had it apart so maybe its not a perfect case study, just in my case?

Yes, the lines can just be carefully bent to meet the master's new location, close to the firewall.

This article is from the Master Power Brakes website, even though it is for American cars the principle is the same, disk brakes need about twice the force to stop compared to drum. The Fiat master cylinder has a small bore, I think smaller than 7/8 inch, the pressure ratings on the chart is from GM type master cylinder with 1 inch or 1 1/8 inch bore. I cleaned up my engine compartment by using a chrome 7 ½ double diaphragm booster with and chrome master cylinder with built in reservoir and 1 inch bore, the mount holes needed to be altered but not much.

If you want to test your system without the booster just disconnect and plug off your vacuum line.
