So I decided to change the brake fluid, was really darkish but the brakes worked good. I open a bleed valve to one wheel and pumped most of the brake fluid out then got some clean rags and wiped inside of master cylinder which had sediment. Then I refilled master cylinder and bled brakes. Front brakes bled fine but rear brakes no matter how much I bleed them still have air bubbles coming out and brakes are now squishy. I did not disturb any brake lines and have been using a bleed brake...
