Brake Fluid Leak

[Subaru_Nation555]

Driving a couple of days ago I notced that the brake pedal felt a little softer then normal. Then sure enough the brake light came on. I refilled the fluid and kept driving. About 40 or so miles later the light came on again. So when I get home I stop the car and pump the brake pedal a couple of times and go look under the car. Theres a puddle of brake fluid under the ABS control module. So my questions is would the whole module need to be replaced or is it serviceable. My Haynes manual has very little about the unit itself. Any help is appreciated. Thanks.

It depends where the leak is. But to be honest, if it is leaking, it'd probably be a good idea to replace the unit, or at least pull it out, and go over it, and make sure there's nothing else wrong with it.

Try and find out where it's leaking.

Yeah, there are a few places where it can leak that you could service. In particular, over on the passenger side there are a couple of banjo fittings whose copper gaskets you could replace. Or if a bleeder valve were unthreaded a little it could leak. Or the M10x1.0 inverted flare fittings might leak if the flare wasn't seating cleanly or if they were loose.

But that stuff shouldn't be able to happen in a system that's in service. Unfortunately in all likelihood the leak is internal to the non-serviceable hydraulic unit,

Have you ever been to Crazy Ray's? It seems like it might be your best bet.

This may be obvious, but I'll say it anyway -- do not drive your car until you fix this! Even if it seems like topping the fluid off every few dozen miles will work, the leak could get much worse at any time.

Oh, and use lots of water to rinse off the part of the car that the fluid spilled on. Brake fluid eats paint.
