Hello guys, I'm having problem with my brake light switch. I replaced the brake master cylinder but the brake lights are running without pressing the brake pedal, I tried another brake light switch but lights still freezing.

Skoda Octavia MK2 2012 manual transmission. 

So, anyone had the same problem before?

Thanks.

Do you mean that you replaced the cylinder with the intention of fixing the brake light fault or the fault occurred after changing the master cylinder?

After changing the master cylinder....

Check the wiring connector nearest the master cylinder, it's probably gone open circuit with the recent disturbance, inspect, clean and reconnect.
