So I'm off to work last Monday, walking through the garage past my truck ('93, 22RE) and I notice a pool of liquid under the front passenger side. Stick my finger in, and it's a clear, low viscosity oilish substance. I figure it to be brake fluid, must have damaged a brake line while replacing the rotors about a month ago, figure I'll fix it next weekend. No problem, hop into my work van and don't give it a second thought. Tonight I go to tear into it and can't find anything leaking, and there's no fluid missing from the master cylinder. Check all the other fluids and they are OK, but now I've got this uneasy feeling about driving it. I'd like to think it was just water from the A/C, but it didn't have the consistency of it.Anybody ever heard of this? Suggestions?
