Chrysler Repair: Question about brakes, buick lasabre, power steering fluid

Question
Hi,
I am asking about a Buick LaSabre 1990. It had its brakes changed recently and following the repair, around a day or so later, the brakes do not brake properly- only go all the way to the bottom, and then they brake. In other words, the brake works only if you know to brake in advance and press it all the way.

I went back to the mechanic and he said that it seems that oil or something war poured into the brake fluid compartment and the 'Master' must be changed and a full bleed and flush must be done as well.

If I think back, around the time of repairing the brakes, I did pour some (not a lot) power steering fluid into the brake fluid compartment- I though it was the power steering section. The power steering was not working well and was making noise so I fugured to use what was in the trunk to fill it up- but I poured it into the wrong section. (Again, I did not pour too much being that it was already mostly full)

In your opinion, is it possible that this little bit of power steering fluid has destroyed the 'Master' to the point that the whole thing must be replaced, flooded, and bled?

The price he quoted me was around 300$ total for the job and parts.

Thanks,
Levi
