Are they powerful enough to EASILY lock the rear wheels on a hydro handbrake?

Reason i ask is, my 3dr is crap, but thats obviously on a cable setup, and was wondering what they are like when you run a wand through them instead?

Was gunna buy a Wilwood 4 pot superlite setup but i reckon its gunna over-brake a mk2 escort massively, even with a bias box.

What are your thoughts?
