My daughter was driving her 2000 AE112 Corolla during the week and the brake pedal went to the floor when she tried to apply the brakes. After pumping it a few times she had enough pedal to get her home. This morning I attempted to sort this out but I can find nothing wrong. I can't find any leaks, master cylinder is full of fluid and the pedal is right up. I drove it around for 20 minutes and its fine. I feel it must be a master cylinder problem for this to happen or is there another explanation. I don't want to just start replacing parts until I get my head around this issue. Has anyone had this problem before? Any information is greatly appreciated. Cheers Coops
