Hi, yesterday I was driving in a storm, when suddenly a "diesel spot" make my car to spin arround, I hitted a fence, and got 2 flat tires. A police officer that saw the accident, helped me to take the out the wheels, and went to a local garage to see if they could fix them. After that, I returned to my car, and went home, the more I drove, the less braking power the car had. When I got home, I had no braking at all, I lifted and got all the wheels out, and saw a rubber brake hose, that was damaged, and was leaking. I went to a brake shop, and bought the brake line, they told me to bleed the entire system after I made all the repairs. So I did, but now the pedal feels very spongy, My car is a civic SI 06, the car stops, but the pedal is spongy, I have no more money left in order to take it to the dealer for this service, I spoke to a tool store, and they told me they could lend me a pressure bleeder, but I don't know how to use it. And many people told me to bench bleed the master cilinder, How could I do This? Thanx?

If allot of air was able to get into the system you may need to bleed your brakes again and purge the abs unit.

Another thing that could cause spongy brakes in your situation is if one of your wheel bearings, knuckles, brake mounting surface was damaged in the accident. The wreck was bad enough to damage your tires (if I read corectly) so you could have hurt something else.
If on of the three things I mentioned above is now not true with the brake disk it could cause your pedal to be spongy.
