    What year corolla? What engine too as there may be different brakes on different models.

    Do you hear the noise when stopped? Park up, open the bonnet and your window and sit in the car and listen. How are you brake fluid levels? What colour is the fluid?

    Was getting something similar in my wife's previous car - an Audi A2. Like you, the brakes were fine. I put it down to a leak in the brake booster which uses air from the engine to enhance braking. We sold the car about 6 months after it started happening so never fully got to the bottom of it.

    Could be master cylinder . Don't trust the brakes much longer - get them checked out

    Have u only noticed this noise now. Quite often there is that slight noise on most cars when u press the brake pedal to be honest.

    Sounds like a vacuum leak from the brake servo unit.
