hi everyone,
my car: 2000 accord lx 2.3L MT
my friend wanted to help me replace/bleed brake fluid.
the bottle we were using to dump old fluid had a little bit of engine oil and mineral spirits in them.
in a moment of mindlessness he siphoned out the brake fluid, and while dumping the old fluid, he let the siphon touch the oil/mineral spirits and then used the same turkey baster to remove more brake fluid from the master cylinder.
i haven’t depressed the pedal or used the car at all.
the only thing is the brake fluid has been swirled in the reservoir using the reservoir cap and the reservoir has been closed with the cap on.
from what i understand, any chance of contamination would be entirely eliminated if i replaced the brake master cylinder right? without having used the brake pedal there would be no way for the contaminated fluid to get out of the master cylinder into the lines right?
please correct me if I’m wrong.
[btw, i see Erics video on replacing the master cylinder so i know how to do it (hopefully). is there an alternative to using a bench vise to bench bleed? and some people including napa say you need to adjust the pushrod clearance. is that true if you are just replacing the master cylinder? i don’t see that in the haynes]
thanks guys.

You, probably, won’t have to worry about adjusting the pushrod, but this is moot because It doesn’t sound like you’ll have any issues. Trace amounts of crap won’t hurt anything.
I like to use one of those syringes that dentists use to irrigate dental work (a curved tip plastic syringe). This is because I can agitate all the sediment in the reservoir, then suck it out.
Just finish your brake flush by bleeding the lines. You can do the “have a friend pump” method or (like I do) just open all the bleeders and let them gravity bleed for an hour or two. Just keep an eye on the fluid level.
