Need some help with brake issue

Just a update, been busy doing the water pump after i did the brakes. Bled them again with the vacuum bleeder and double checked the rear adjustment. Pedal still felt a little low to me but seems like it was pretty firm, ordered a adjustable brake pedal rod and brought the pedal itself up maybe 3/8 to 1/2”. Pedal was firm a little higher but not like rock solid. So the crazy part is once i started the car the pedal immediately felt better like it should? Lol idk maybe it was just happy, took it for a short drive and all seems well! No leaks stops great. Does pull slightly to the right while braking hard but i could not rule out the road or tire pressure. Only have about 15 miles on the brakes with a handful of stops so need more time for the pads and sjoes to wear in
