I recently had my EPB flashing, along with the red flashing brake icon and the parking brake icon illuminated on my dash. They stayed on for my entire drive and the next morning...poof...gone. the dealership today said my parking brake module is responsible and malfunctioning. I've tried to find some research online about this but am coming up empty. It is a cool 600+ dollars for them to fix. Could anyone shed some light on what this actually means. Does it absolutely need replaced. Can I find the parts online and replace it myself. Or try a cheaper mechanic other than Mazda!? Help!
