Installing Hydroboost and bigger brakes in a 1970 Charger

Says who?
Hydraulic fluid gets hot under pressure so why not take steps to cool it down ?

The instructions from Hydratech made no mention of additional fluid requirements or a cooler.

I agree with @Kern Dog Fluid under pressure gets hot. Two ways to cool it.
1. cooler
2. Additional fluid.

So what? You think that they thought of everything and are above question ?
With the way that so many vendors are, you're lucky to get any instructions at all when you buy stuff.
