My dealer left the master cylinder cap off of my car which I have been driving for the last week and a half like that (I don't know how I am still alive)
Is this even possible that I have had brake pressure without the cap?
Anyway, do I need to flush the system? Isn't brake fluid hygroscopic (absorbs moisture)? It has been raining almost every other day here. I am afraid that I might have gotten a ton of moisture in the system.
My Dealer Sucks! This was just after fixing the ABS problem. They even left my car unlocked in the back of the lot and someone left a chew cup in the pass. seat.
