When there is a lot of moisture in the air and a vehicle sits for hours, a film of rust will cover the rotors. Then when you drive the car and apply the brakes, it can make a grindy noise and feel a bit grabby because the brake pads are cleaning the the rust off the rotors.
If you feel the brakes are weird or unsafe, I highly recommend you have your regular auto technician inspect the brakes of your Acura to make sure they are working properly and there is enough life on the pads and rotors to be safe.

With the moisture/humidity content is higher in the atmosphere, surface rust forms quicker on your brake rotors. This typically wears of within the first few applications of brake pad/ rotor contact.
It*s likely to be a layer of rust. When you use them a few times it will wear off

Hello Patricia- first check the brake calipers for any signs of brake fluid leakage- that can cause them to grab until it burns off- second if the car is in a humid or wet climate there can be water or condensation that can cause this also - the only time that it is a major concern if you have leaking calipers as that can lead to eventual brake failure- hope this helps - thanks Super Girls Auto.

The noise is definitely normal. Brakes rotors can have condensation on them in the morning and it usually takes a few applications to heat them up and dry them off. If the brakes actually feel different, it should be very slight. If your brakes are grabbing excessively, to the point that it could be dangerous, I suggest having them checked out by a qualified technician. You may have to leave the vehicle overnight so they can experience the problem.
