Brakes make a weird noise!! help please

[In2myCobra]

Just started the car from the new build! It runs beautiful. When I stepped on the breaks to turn the car off (car was sitting still the entire time) it makes a weird ass noise. Sounds like a Belt is slipping or somthing is grinding against the belt! Any advice on what this may be?
Thanks!

Might be a dumb question but did u check the power steering fluid? The hydro boost runs off the power steering pump

At one point when I first started the car there was also another noise, sounded like a grinding/rubbing coming from the power steering pump pully. I noticed the power steering fluid was low so I topped it off and walked away for a while. I came back and started the car about 30 mins later and the ginding/rubing noise was gone. Maybe it fixed the brakes as well? I never thought about it though, ill try tomorrow morning and post the results here! Thanks buddy!

Yeah when the pump is low it will make some nasty noises. I did the exact same thing after my rebuild. Filled up the reservoir all was good and when I went to take it out I pushed on the brake and had that bad grinding sound (pump was low again).

Cool hope that's all it is!

Checked this morning and everything is perfect!! (Other than a small power steering leak coming from the "resevoir to pump hose") Thank you very much!
