Default How does a brake job cause a power steering leak?

I know some '99 LS400's have a problem with power steering leaks. I would add around 8oz once a year. Monday I had my front and rear breaks changed (shoe/pads) and the next morning the steering was tough. Now any PS fluid added runs right through. What could lead to such a acceleration? (I'm looking to brake shop error over coincidence, because they also forgot to tighten the lug nuts on a wheel which almost came off a few blocks away.)

Thanks for any help or insight!

I just changed my rear pads and front rotors/pads the day before yesterday. The brakes have nothing to do with the power steering system, and the power steering system isn't impacted at all by a brake job. I would have to lean toward coincidence unless the shop you are using intentionally did something to your power steering system in an effort to generate more work for themselves.

Where is it leaking? These are two separate systems so it is possible that the PS timing happened as it did.

Keeping the fluid in good condition prevents particulates from causing clogs and leaking from fittings. Invariably they all being to leak from the IACV. I've sucked out fluid in increments each time I do basic fluid changes that works out to be about 4 oz. every 15K. (Same interval as the 2 qt. tranny fluid drain which makes this easy to remember.)

The two systems are about as independent as possible. So it is either coincidence or sabotage.

I had to replace my return hose as well due to being brittle/hard. I think the hose was original and almost 20 years old so it was to be expected due to being located somewhat near the right side exhaust heat shield.

Either mine was bad when I bought it or coincidentally went bad on the way home (which I doubt) but my pump AND high pressure hose were bad. The high pressure hose cost almost as much as the pump too, ugggh, hopefully it's not both for you also. But I couldn't see a spot where they might intertwine which would cause the issue.
