Have you replaced your rear pads or calipers? May have air in the lines. The reason the E- brake works is because it is engaged by a cable and has nothing to do with the hydraulics of your brake system.
In some cases you can disconnect the plug on the ebrake switch. I was able to access it by pulling back on the ebrake side cover.
Put it in gear
what knds of car do yoy have .
with your ebrake cable.
Check brake fluid level--I believe both service and "e" brake use the same light. Low brake fluid could indicate leak (Need service NOW) or brake pads need replacing due to excessive wear Try engaging the brake all the way then releasing it. It might just be sticking. The ebrake sensor could be malfunctioning. It is usually located along the ebrake pedal somewhere. Hope this helps.
the wire needs ground to function. Connecting it to the ebrake allows it to ground so just connect the video wire to any ground and it will function as if it was connected to the ebrake
usually this is done at the ebrake itself. there are two wires going to it.
press your ebrake one or two clicks and leave it on
put in reverse and go about 5 then slam it into drive and gas it to the floor or u can use the ebrake and go half way so you dont burn out the transmission and make sure that your ebrake is fully tightened other wise it wont work
Right next to the ebrake there is a pop off plastic door. There are your fuses.
Check the brake fluid reservoir, it is probably low. Time for a brake inspection.
