[Bryank]

k thanks. trying to eliminate or move the steering and brakes from the firewall as much as possible to make the boxed in front end different. only other thing to move would be the windshield wiper motor but thats no biggy i guess.

no. i have a Wilwood floor mount unit in my truck. i got it for 100 bucks thru jegs it works set too. Its only 4"x2" mastercylinder so it can fit in tight areas

i got an 85 chev i had to get rid of booster on, master cyl bolted right to firewall where booster did.  shorten plunger rod and a brace or bracket to keep it from coming out of position. seems to work good and i'm only running front disc brakes.

did the same here, bust your booster up and get the rod out of it, and on your brake pedal the plunger rod stud has two possible locations, you will need to grind the weld off the stud and put it in the other available hole to correct the rod angle. Also use a spring from pedal to floor to keep the rod from falling out. It's all easy to do
Edit: the pedal stud was on a chevelle, might be diff than truck pedal

Did the same thing.   Then plugged one side of master and ran 1 new line to rear rockwell pinion brake.  Works great.

Im wanting to do this to my truck. Just seems like a pain in the ass with the whole rod thing? How bad is it?

easy, especially in a truck. I did it in my chevelle with the doors welded shut and I'm 250 lbs, lol.

only on the s10, on the k5 I did not

What is the reasoning for doing this? Just wondering

[Mudgrunt]

With uprights they are sometimes to close to the master cylinder and will boil the brake fluid out then no brakes.

my reason was the booster broke off, leaving zero brakes

Thanks guys I haven't gotten to put the uprights yet on mine. But good to know!

i'm doing it for valve cover clearance and more convienant for boxed in front end and it will give me a vacum for a pcv valve seeing how intake didnt have a extra port.

[Bryank]

do ya gotta bust or cut up the brake booster to get the rod out?

[Mudgrunt]

yes you need to pry the booster apart then just keep on taking things apart until you have the rod in your hand we had to brake some plastic parts and cut some other pieces but once you get the booster apart you will see what you need to do. once it's apart there is no turning back.

just get the rod out of a 82 or 83 plain jane chevy truck with out a brake booster, came in straight 6 3 speed trucks
