Crazy Brakes HCU Test

I have a 2002 Convertible GT with brembo Gt 14" front and stock R calipers with 13" rotors. I installed new HP193 hawk pads F and Ceramic pads R I used a power bleeder to bleed the MC and calipers. The pedal is super high and very hard and after driving a mile or two all four brakes apply and don't release from the rotors. The car dozn't pull ether way and when I jack it up all four wheels are lock up. About a hour later (cooled off) they release. I think I have a set of Crazy Brakes. I'm not getting any codes out of it. The only thing I can think of is when the calipers where hanging it damaged the R brake lines? Has anyone else had any issues like this. Anyone know how to test the HCU?
Thanks Michael

I was thinking the same thing but no ABS light on the dash panel and no codes on the obd2. Do you know of a way to check the ABS HCU a new HCU is about $1200 bucks that would really hurt this time of year.

Ok so I was thinking the hard brake pedal was the the HCU but it was not. When I did the brake job I let the calipers hang down on the brake lines and it damaged the lines. This was causing a restriction and making the pedal stay hard. I installed new rear brake lines and all is good normal brake pedal..
