So i just recently bought a new ef but the brakes are bad the brake pedal goes down all the way down easily the brakes work just a little bit but when the brake pedal is all the way to the floor, So i took off both of the front tires the pads were in good shape rotors had little tiny dots of rust on them not to bad.So after inspecting that I bleeded the brakes and the brake pedal still went to the floor,So maybe I thought it would be Master cylinder or brake pistons what should I check?I topped off brake fluid that didnt help either.Help would be very appriciated Thank you.

 

look for leaks. if theres not leaks check inside up under the dash near the brake pedal. probably your master cylinder.

 

How did you bleed? Did you try just to bleed the front?

 

X2, where the pedal is, right above that is the actuator that goes into the brake master, if its wet or has signs of being wet (should be clean black rubber boot) like moist dust caked on then its master.... if everything looks normal, move on to checking ALL the lines
