On cold morning starts, front brake pads will engage rotor, and release very slowly. Then on a turn, front pads will engage, lock for a short time, and then slowly release. Seems like engine has to warm up before brakes act normal. After cold morning startup, before moving vehicle, if brake pedal is pumped repeatedly for 30 seconds, brakes will try to act normal, when vehicle is moved. I am on my 2nd set of front pads and rotors. 1st set were severally worn. Tech said it looks like your calipers were sticking.
