brake issue
i have a 91 integra... it jus had a freind replace the master cylinder and i helped him bleed the brakes but the pedal is not firm and goes to the floor, now i asked him if he had bench bled the master cylinder and he did not would this still pose a problem even tho we bled the brakes at the calipers till i could not see any more air coming out? is it possible there is still air in the lines? whichorder are u supposed to bleed the calipers in? could it be the booster?
