I've used those kits a few times.. .seals should be right
So you're getting no fluid ?
Did it bleed OK at the master before you put it on ?
Did you bench bleed it first ?
Masters should be bench bled first to make sure they are working and providing pressure and compensating on release (you can hear them such back on release
If its not bleeding at the master before it goes on the car... need to address that first
Then bleed at valve... to make sure fluid is getting there... then after valve... to make sure its getting out.... then pre hose... then after hose... then at wheels
This is for a fresh unknown system... which I assume you have
I know all that fluid around will get scary on the paint... but wash it off fast and should be OK
