yeah I thought the same thing until I took of the cap. So how come is unsafe to drive around with a hairline crack above the max fill line? Those the reservoir work like the coolant overflow tank?dieseldorf said:It's weird, I had the EXACT same thing happen on a 1998 Passat. Friggin' brake fluid went everywhere
It took quite a while to figure out what had happened. I thought the gasket in the cap had given away. The crack that opened up was very fine, very difficult to see.
The new plastic housing is around $100
Probably more like months unless you live somewhere tropical.srmichi said:
Provided you have sufficient fluid so that it doesn't suck air into the piston it shouldn't matter. It is only a reservoir, but I wouldn't want to risk leaving it that way for long.
