I have bought an axle with the rear disk brake swap done, but I have to get a new brake booster. I also have a low budget so I was wondering if this is a good booster or not. http://shop.advanceautoparts.com/web...zoneAssigned=1

 

thats a master cylinder not a booster. the booster is the thing that pulls vacuum from your engine to make your braking stronger, the master cylinder is the actual rod that acts on the fluid to push the brakes.

im confused why you need a new master cylinder, if its to push more fluid i understand but i feel like the more likely scenario is the stock master cylinder is set up for drum rears and with your new disc brakes the proportion of brake fluid that goes to the rear is going to be too high and they will lock up.

In this case you need a proportioning valve plumbed inline, summit racing sells them.

 

helps to know what year/model you are putting this thing on.. I have a dual diaphagm(sp?) booster off a turbo truck i will use on my '81. that combined with a bigger master cylinder should be able to lock up my 35's

that mastercylinder you pictures looks like a chevy master cylinder...are you doing a conversion to a one ton MC using an adapter?

what are you plans for an ebrake?

 

you will need a 1" bore master cylinder, if it is not standard.

you can use the stock booster.

i recommend an aisan oem mc, got mine from trail gear.

drive shaft disce-brake from all pro offroad is an option, if you have a gear drive transfer case.
