Default Brake master cilinder is leaking steering fluid
Hi, my brake master cilinder is leaking steering fluid thrru a small hole beneith, right on top of the brake boost preasure switch.
Anybody knows if there is a retainer somewhere that separates both brake and steering fluids?


tks

Default your master cylinder isn't leaking hydro fluid
it would be the brake booster, which is what the master cylinder hooks up to.

But, does the steering fluid pass thru the brake booster?

Default Pretty sure...
...it goes from the res to the bomb, the bomb to the PS pump, the pump to the rack, and back to the res. 4 hoses, I believe.

iirc, there are hard lines that go to the booster, from the bomb

Yeah, you're right. There's one that angles off.

Default Check the rubber grommets that seal the reservoir to the Master cylinder
/......... strange that my 1993 was leaking at said junction. easy enough fix by R&R the donut rubber grommets.
Just a thought.
