240sx brake pedal hits floor!help

[bestlowrida]

Hey guys , I got my car towed home with the caliper detached from rotor on the front, hit the pedal and the pedal hit floor before it grabbed to stop. A week later I put everything back together and pedal hits the floor. Bled the brakes and the pedal was back to normal. About 2 days later I come back to test drive the car and brake pedal hits the floor any help wold be appreciated, of course searched and didn't come up with anything helpful, the brakes were fine before the tow, thanks you guys are the best!

Brake master cylinder or your brake booster is leaking somewhere. Bleed system again as you might have air in the lines. Did your brake fluid go down in the reservoir?

Do a visual check for leaks around the master, calipers, lines and hoses.

Does it have ABS?

non abs, fluid DID NOT go down in the reservoir, funny thing right when I was going to do a quick check for leaks the pedal was back to normal WTF , I didnt drive it yet ill come back when I finally have the strenght to drive the car thanks for all the replies
