i just resently replaced my back roters, calipers and brake lines and had no problem bleeding them or replacing them and theres no leakes or kinks in the line.
But heres my problem, when i press on my brake pedal my brakes just tighten and dont release. Please help

 

Open the bleeder and see if they release.

If they do then one of the rubber lines are bad.Does all the brakes stay locked?
