My front brakes keep constant pressure. I replaced the brake booster master cylinder calipers brake pads and flush the system twice. Nothing has eased the pressure of the front brakes. Can someone please suggest something else it may be?

Could be your calipers/pistons are sticking. On an older pickup like yours its very possible. Did you put any disk brake grease on the caliper retaining bolts?

Yes I did I replaced the brake booster the master cylinder the calipers have put new brake pads in I got the grease product is there any way you could be the ABS system? I even went as far as following all the copper lines or steel lines whatever it is all the way up there's no leaks I bled all four brakes last night. I followed the copper lines and everything to to see if there were any leaks copper steel whatever it is. I've dumped about 350 to $400 into my brakes front brakes will not let up pressure.

what about the flex lines? they can act like a check valve when they deteriorate.

It's the flex lines as tech 2 said. They break down on the inside. You will not notice any thing wrong on the outside. It's very common on these trucks.
