BIG OOPS!! Power Steering Fluid in Master Cylinder Reservoir

[DrewP]

OK.. I'm admitting this up front, so I'm owning up to my mistake.
I put Power Steering Fluid into my Master Cylinder Reservoir and drove for 2 weeks ....
Now I'm dealing with my brakes locking up... I assume, due to rubber seals swelling and not allowing the fluid to return to the Master Cylinder Reservoir.
Other than using my Jeep as a boat anchor ... I assume flushing the system, replacing the Master Cylinder & Reservoir would be my first starting point ... ? Correct ?

At this point after driving two weeks , I would replace the master cylinder and refill it with brake fluid, ( bench bleed it ) then bleed the whole system well, going through it several times , RR, LR, RF and then LF
You may of lucked out ,
if not replace all rubber/ flexible hoses, calipers, etc
Its not a boat anchor,...........yet

By "power steering fluid", do you mean actual labeled "power steering fluid", the clear-ish stuff? OR do you mean ATF+4, which the Jeep uses as power steering fluid.
