I used 15A ext lead doubled up because stones and its what I had ;)
but um,, we are talking front car brakes...... :)
Admittedly This is my first time using the redarc pro,,, van brakes work fine with manual application and I can feel them doing stuff on the road...
I really dont think it has anything to do with the van...
I have it booked in to a workshop that has a proper automotive brake tester, but regardless am putting new kits through both..
