I just bought a 2004 RX330. When I test drove the vehicle, I thought the brakes felt soft on the first stop, but then the brakes felt fine the rest of the test drive. So, then I wasn't sure about that first stop and what I felt, since I couldn't recreate it. Now that we have the vehicle, every time we turn it off and restart, the pedal nearly goes to the floor on the first stop. After that, the brakes are fine.
I've checked brake fluid and topped it off, still same problem. I'm going to take it in to have it checked, but has anyone ever experienced the same thing or have any input? I've searched and can't find a topic that matches this problem, so any help would be appreciated. I've seen some topics on a TSIB for a Brake Booster. Could this be the problem?
