In an extremely dim moment whilst servicing my car and flushing the brake fluid it was replaced by power steering fluid. This was bled theough the system. Mistake was noticed as soon as the job was wrapped up and was then flushed thoroughly with brake fluid.
It seems fine now but after google searching the future of my break system does not look good.

I understand that PS-fluid is toxic to rubber components but might it be it will be ok as rhe exposure time was hours and not days. Also if everything needs to be replaced can someone please point out exactly what parts we are talking about. The parts I know will need replacement in that case:

- brake master cylinder
- ABS?
- Rebuild all four calipers
- clutch master cylinder

was it power steering fluid or hydraulic? (i think VAG uses hydraulic)

Being picky, PS fluid is hydraulic fluid. But anyway, it doesn't really matter because in either case it will be a mineral oil, which is what you don't want in a brake system.

I'll admit, for such a safety-critical system I'd want to be sure everything was in order, which means new seals in the calipers and master cylinder at the minimum.

Thanks for your replies. If I start replacing stuff I think I will do all rubber bits to avoid new contamination.
So does anyone know where these would be except for the ones I have mentioned?
