Has anyone deleted their power brakes and gone to a complete manual system for a drag truck? I would like to eliminate the the hydro-boost and all the ABS stuff. I have seen a few pullers do it but I don't think stopping power is as much of a concern. Again this is for a drag only truck, no DD. I see Wilwood makes several types of mastercylinders that should work. Thanks.

Is this for weight savings? I can see wanting to delete the power steering pump and all that leaky crap, but removing the ABS module sounds like a lot of work for 2lbs weight savings.
I have not heard of anyone doing it, but I see no reason it couldn't be done.

I deleted the ABS pump on the van but not the hydroboost. I've been wanting to get a manual steering box and swap to a different master cylinder so I can ditch the PS pump, but I haven't had the time to really search out what parts I need to accomplish it.
The truck is stripped down already, no interior at all net even a dash. It will have a stand alone wiring harness so the fuse box and all the dash wiring is gone. It will also have a duraflite so not TCM or wiring. Eliminating the hydro-boost, power steering and ABS will really open up the drivers side engine bay and a few less things to worry about.
X2. I have driven a few and couldn't imagine trying to rein in 1000+ horsepower without some type of assist. What if you ditched the hydraulics and went with some type of vacuum assist with a small vacuum pump and plastic reservoir? That should save some weight
Looking at something like this. Post 156. I am sure this guy will be well north of 1K.

its all dependent on the correct sized MC, calipers, rotor size, and proportioning valve. you can make a car stop damn fast without assist and not need a "popeye leg" to do it. Look at desert trucks/cars. those are 5-6k lbs vehicles that damn near stop on a dime with 40" tires.
I didn't realize those were non assist brakes. I guess with enough experimentation and research it's possible
It's all math. It's not hard to figure out once you know the properties of brakes. Our only issue is the only variable that can easily be changed is the master cyl. If one can be found to push the correct amount of fluid, it will work well but that's gunna take some time to figure
What bore size?
I know the conversion can be done just not sure what size master cylinder to use. Keep in mind the smaller the bore the more clamping force you have at the caliper. Here is some info on the subject.

This is what the one I was thinking of using.
