Hello,,,
recently while under hard braking the "Brake" light will come on momentarily then go off. any idea what might cause that?

also randomly, the ShowBox Mobdro VidMate SLIP and VDC light will come on halfway through my 10 mile commute in the morning.
Thank you,,...

For your fist question its a classic symptom of low , but not ctastrophically low brake fluid.

My recommendation is to add some brake fluid.
Am unsure about the other symptoms but it wouldn't hurt to try the upfill and see if other symptom goes away.

Brake fluid level, as suggested already, is a good place to start. Is it possible that the traction control system engaged during your "heavy braking" incident? If so, the lights coming on would be normal. As far as them coming on intermittently while driving, that's another issue. It may or may not even be an issue with the traction control system. If there is an engine management issue (for example, a faulty cam position sensor), the ECM will disable the traction control system and the VDC/SLIP lights will be illuminated. If it is traction control related, most of the time it's related to one of the ABS wheel speed sensors or, sometimes, the ABS control unit, but excessive play in a wheel bearing could also cause this. A generic OBD II code reader can check for stored engine management codes, but a diagnostic tool with ABS system capabilities will be needed for accessing those trouble codes and/or reading live data to help diagnose the issue.
