My brakes keep acting a little funny, or it could be just me switching back and forth between vehicles soo much.

Awhile back I changed the master cylinder, front calipers, front disks, bearings, hoses. Then later I did the whole rear end brake system. So only thing left is that brake booster. So what are the symptoms of a brake booster going on its way out?

If the BRAKE pedal is requiring more and more force to stop or slow the truck that is usually a sign of a leaking BRAKE booster.

its pretty loud and most the time it goes away when you hit your pedal and the sound is always there

Did you manage to put the heavy duty master cylinder on your truck. If you did you will have slightly less pedal travel along with heavy pedal pressure required to stop. The master cylinder should almost fall over the studs from the booster, if any forcing is required you have the wrong cylinder.

I did not get the heavy duty. I got the right part. And I did think of that. Thanks! Im pretty sure its just me at this point.

did u bench bleed the master cylnder and the whole system after you did all that stuff? air in the lines or clapers or drums could give u the same symptoms
