This is probably going to sound smartassy but it's not intended to be.

Have you ever used your e-brake?

Till you get this anomaly figured out I'd suggest that you actually use the e-brake a few times, you know, in case you ever really need to you'll know how it reacts.

A lot of people just take the e-brake for granted and never use it or never really know how to use it when the immediate need arises.
