great , object of exercise being i.d the condition of the disks !, it did not sound like them but ya didnt mention them, just crossing out a blank.
edit, btw.. go and get some use into the new pads before you get it into the test place, go drive round a few housing estates carefully, try and bed the pads in a bit more , you can have the best rebuilt brakes in the world, they will still have a reduced braking force until they bed in proper.
slotted and grooved discs and ebc red stuff pads.. (assuming all kit is new) don't share so much the same failures!..they just stop you quick.
old disks and new pads is bad, i used to re-dress my discs on the lathe if i used new pads.
