My '91 supra pulls hard to the right at moderate braking.

What is your question?

Just bought the car so no real history. 100% bone stock. The pads are newish. I went to bleed the brakes and the passenger front when I opened the bled valve pressed easy to the floor as fluid came out at a descent rate. I went to bleed the drivers side. Fluid coming out slow. Disconnected the hardline from the flex line at the wheel well and same issue. a little coming out and the pedal is hard to press. ABS module issue? Can it be cleaned? Would a professional flush maybe fix it? What is the next step?
