Ok, heres the deal. I installed my front brakes ( 94 Integra ) in my 97 civic hatch. Everything went in fine, but I went to install my rear brakes this weekend. When I installed them, it was pretty straight forward, and I got the proportioning valve from what I'm told was a 99 civic si. Well after I installed everything, there were a few small leaks, so I tightened all the lines up and thought I had everything ok. Well the front left line broke ( goodridge steel braided line ). So I went out and bought a line, because I need my car ( daily driver ). I bought 2 soft lines. I installed them, but there was almost no brake pressure when we started the car up. I had pressure when we bled the brakes, but after start up, the peddel drops to the floor. While driving on the of the soft lines snapped and i replaced that with the good steel braided one. But again there is still no brake pressure. I don't know what it could be. I need help asap!!! Thanks

 

sounds like you have a leak somewhere and that the brakes could've been bled improperly

 

definitely leak or still air in lines cant be but few things if brakes a functioning properly as far as calipers

 

check the seal on the cap of the brake master cylinder might be bad and might not have any pressure to build up

wrong , you can run without the cap and still have pressure, the cap just keeps the fluid in the resivoir, the pressure is in the internal cylinder
