pads are newish bendix advance front and rear
There is your biggest problem, I have these on the rear of my na6 and they are RUBBISH. They don't do anything except polish the surface of the disk, they haven't worn them away at all and I have been to several track days, the Hawk HP+ on the other hand are brilliant, stopping power is amazing and I was surprised how slowly they wear despite the dust.
Go get some Hawk HPS for the street or HP+ for the street and track days, you will then experience what brakes should be like.
Pumping the pedal once or twice brings back some pedal and the brakes work 'normally'
Second problem, if you are having to pump the pedal to get the brakes to work, then you either have air in the system, or your pads are being pushed away from the rotor too much and you're have having to pump the pedal to get them to move in. Bleed the brakes properly, im not too sure how the whole abs thing works, I would have thought its all the same fluid and you just bleed like usual (pump the brakes and undo the nipple with a hose on it). Then take apart your callipers, buy some metal toothbrushes, clean up all the buildup and crap with them and brake cleaner then buy some high temp brake pin grease and put it all over the slider pins and the part where the pads slide (not the surface). Then perhaps get the disks machined.
I'm not sure how Gavin's car is now with the new pads but you could sent him a PM if you want to ask him, I think he got the Hawk HP+.
But I definitely think you should take off those advances.
