2019 chevy colorado v6, changing the oil and just completely was not paying attention to what I was doing. Put probably a cup of oil into the brake fluid reservoir before it overflowed and I realized how dumb I was. I know this is a huge deal, tried to get as much out as a I can and im taking it to the shop today, what can I expect? Any chance of draining and cleaning working since it just happened or will they have to rebuild my entire braking system?
