Brake pedal sticking down when on inclines

Just had brakes and rotors done on my car DCT F80.

Pedal feels fine normally, but when stopped on an uphill, when I release the brake pedal it sticks in before it springs back.

I'm assuming it's the hill assist feature doing it? Is there a valve or anything that could have a bubble in it?? Never did this before.

Thx!

Yes, hill assists.

Maybe I didn't describe it well.

I'm very familiar with the hill assist feature, but this is a clunk when I let off the pedal and it stick down a little. Definitely didn't clunk before brakes were replaced.

Could I have a sticky piston/valve/guide pin?

Or the pads releasing causing the clunk within the caliper.
