Front brakes sticking when cold

    I've noticed when I've not driven my car in 3 days or more, the front brakes stick from cold.

    When reversing out of the space from cold, I can hear a clunk as the pads free themselves from the surface of the disc. This does not pose an issue at any other time other than when first moving the car.

    The calipers are Brembo 4 pots.

    What is the likely cause of this? Air in the brake system?

    I may add, there is a very slight warping on the discs. Hoping to get them changed soon.

    What pads you using mate? Also what car is it?

    After a spirited drive when you stop your car use the handbrake to lock the wheels, not the brake pedal, that can cause binding and scorching between the disc and friction material.

    OEM pads. It's a 350z.

    I wouldn't have done any spirited driving just before parking her up. It's only when the car has been sitting more than 2 or 3 days.

    Brembos not prone to sticking afaik, however mounting bolts are but thats a different story. OEM pads usually have terrible heat tolerance but they bite from cold.

    It would worth checking the rubber boots on the calipers themselves, also check for rust.
