    E Parking Brake Does not Disengage

    Picked up a new 981 Cayman S last weekend. Had the "Fault Electric Parking Brake" warning come up on my drive home. Shut the motor off and on restart the "Fault" warning went away - - I decided not to follow up. Today, I parked in my office lot and pressed the E Parking Brake "button." Seemed to work correctly. Came back a few hours later and started the car. The "Fault" warning had now come back and this time I could not disengage the e brake at all. The wheels were locked up tight and there was no way for me to "drive" out of it as stated by the owner's manual. Tried a number of times to disengage but no go. Has anybody else gone through this - - specifically the inability to disengage the e parking brake?? I did review orangecrush's thread from this past March. I have an appointment at my dealer for service in a couple of days. If anyone else has had this issue, I am interested in how you resolved/dealt with the problem.

    Try driving off without disengaging the hand brakes. Just make sure door is closed and seat belts is on, this enables the "intention to drive" and disengages the hand brake automatically

    I am curious if it is this way for others. If the ebrake is on and you are on a incline where the hold function would also be active trying to drive results in a jerk and then a message to release the ebreak.

    Btw other than that I've not had any issues with the break and I do use it often. Sorry about your luck. I'd love to heard how the car was taken to the dealer for service - did you finally get the break to release?

    Thx for responses. Could not drive off, brake would not release a bit and wheels were locked very tight. Tried to overpower the lock by rocking the car as much as I could but that did nothing. Was not parked on an incline - - flat parking lot. I had arranged for a flat bed with "skis wheel set" to pick the car up. But while waiting I started playing around with some of the control stalks and somehow that ended up releasing the car. Don't ask me how, I have no idea. So I'll be driving the car to the dealer and see what they can find out.

    I had the same issue twice with my Boxster. First time it warned me of a faulty E brake and the car wouldnt release the brake, so I turned off the car and turned it on again and it went away. The second time the message appear while driving and I noticed the car wouldnt hold the car in an incline (which felt kind of cool to go back to how I use to drive manual cars), but once I parked my car at home the car wouldnt engage the E brake. This was during the first 300 miles of the car. Havent had any more occurences since (2200 miles).

    Re: E Parking Brake Does not Disengage

    Ok, just passed 1500 miles today and parked the car at the folks for 3 hours in the rain. On start up the "release e-brake" message came up, but I had already started to reverse, so the brake disengaged automatically, followed by the "fault e-brake" warning. Switch off then on and the fault message was gone. Only engaged the brake once at a stop light in heavy traffic going home (nervously) and it released as usual?

    Does anyone know if this is a mechanical or electrical/software issue?

    I would much rather the old manual method where one could manually pull the emergency brake up with their hand. Imagine your brakes going out and needing to use the handbrake Like someone would dare push/pull that button.

    I've been driving since the 1960s. I have never needed to use a handbrake to stop a moving car (and I've driven some cars with really poor brakes).

    FWIW, I tried it out of curiosity on an Audi. Don't do it. :-)

    I tried it on my 981S at 60mph. It doesn't do much. I know, manual warn you about "severe braking", but in reality, engaging e-brake at speed is just like slightly pulling your hand brake. You'll need a long time to stop the car that way. Engine braking will be much more effective than our e-brake in case of emergency.

    Re: E Parking Brake Does not Disengage

    I'd also prefer a manual parking brake for reliability's sake, especially on a sports car, and with no dealer anywhere close. Will have to learn where is the control module, in case it fails in my car. Getting stranded for a stupidity like that woudn't be fun at all . But all cars are switching to electric steering, electric parking brake, automatic-only transmissions.... you name it.
