No brakes. No power steering HELP ME🙄, how do I test this? Hydro boost?

 

Any warning lights or messages on the dash, such as check charging system?

If they both quit suddenly, the first things to check are:

1) The serpentine belt failed (broke) and the pump pulley isn’t spinning, which would also cause the alternator to stop charging and set the warning message/light.

2) The pressure hose burst and fluid is leaking; or it could have collapsed and is causing a restriction. Either one would likely cause pump noise.

3) An internal component to the pump failed and it needs replacement.
