Not sure if this been covered

I have a 2010 chevy equinox. I remember few years ago I was having issues with tc light and stabilitrac light coming on. Felt like my brakes were locking up and car wouldn't move. This could happen anytime. Would seem fine for a day or two then lock up again. After looking online I never found anyone that had an answer. Well I may have one, not sure if this has been mentioned already. My brake master cylinder was leaking into brake booster. Messing with the vaccum. Causing brakes to compress. I had to replace master cylinder and the booster. No issues since. Dealer even said they had never seen it.
