There is a PCV-type valve on your brake booster that has about a 3/8-1/2" vacuum line coming from the engine. Check that valve and the hose for leaks. Sometimes those vacuum valves will crack pretty easily with weather and age.
Got the same problem replaced everything but the abs pump and power brake booster, have you found what is the problem yet? Any suggestions...
Did you replace the lines when doing all the work, the lines are the cheapest part of it all

is there a rubber brake hose? if so it could be collapsing inside
SOURCE: abs, brake, and battery light
try to jump start your car and disconnect negative battery terminal if the car dies your alternator probably is bad. take it off the car and bring your alt. to autozone for a free test. by the way it would help to know year and model and year. have a good day.
p.s check your brake fluid level

If it makes 1 click for every time you push the brake pedal , You probably didnt notice it before you did the brakes but the noise is a shift lock solenoid , normal.
SOURCE: My front brakes were grinding
my first suggestion would be to take it apart and re-inspect everything. double check that you have it put together right. when you install brakes you should be able to turn the rotor and hear if something is rubbing. if all is on right then you may have a caliper that is hanging up and engaging the brakes all the time.

Hello and welcome to FixYa!
When you open be bleed valve, does the fluid flow solid when brakes are applied? If yes then the problem will be on the hydrovac. You can have a vacuum leak that's why the brake pedal stays on the floor. If the fluid is not solid then you'll need to bleed it out some more. You may need to replace the hydrovac to get your brakes working normally again.
Hope this helps and thank you for using FixYa! Have a good one!
