parking brake issues

[dander2400]

I just got a calibrate parking due to low battery level -12v. I applied the foot brake then engaged the parking brake. Got parking brake applied. Then disengagedvit and got a series of clicks but then service parking brake?

Second issue is I don't show speed or time in the center display?

What is showing then you won't show a clock depending on software level . If the check engine light is on won't show what speed your driving at . As far as the parking brake you can try a hard reset if you have tried the normal calibration .

Hi,

I have had issues with my handbrake on/off the last 2-3 years and I have been able to fix by hard reset or just trying several times. It has happened to me like once a year.

I get a warning of that calibration is needed but calibration process fails with two times clicking sounds etc.

This time I can’t get it fixed. I have had a look at the wire (as read on this post) and the brake mechanism and to me and to my non Fisker tech everything looks OK.

Can anyone in here from the picture and video guide me to what I shall try next?

The picture is of the wire and the short video is about what happens. The system just keeps releasing the brake for some reason.

Thanks in advance.

Thanks in advance.

Check inside the two connectors on / from the actuator, maybe water or oxide inside.

Check the movement of the brake calipers and the thickness of the pads (brake pad thickness is essential for the system to work and whey can wear down if the brake calipers is bad or doesn’t move freely or if the calibration has gone wrong).

It is essential that the wire from the park brake assembly and the brake caliper can travel freely, the park park assembly counts the turn of the motor (information is sent via a hall sensor, the small connector on hand brake assembly) in order to determent the movement / “travel way” off the wire…

There is also a slight possibility for water to get inside the park brake assembly and it will destroy / corrode the gears inside (you have to pull of the plastic cower to find out).

Your Parking Brake Actuator Module might be bad but I would check the mechanical status first. Your system seems to work but it “back off” (probably) since the number of turns does not match the “travel way” of the wire, the system also measures the consumption of the electric motor as it tension the wire in the end position. It may also be that the information never reaches the actuator module or a faulty module…

(I might have some parts if needed).

Thanks SirCastic for the suggestions.

I do hear a noise from the right rear wheel when the car rolls slightly so I think brake caliber/pads/adjustment could be the case. I will start with that.

My wire and brake motor should be fine, I tested it when this happened last time just 3 months ago.

Also been in touch with Peter from Kroymans Fisker, he also recommended to check the djustment of the brakeshoes from the parking brake.

Thanks, I will update you once I have had the car to a workshop.

Hi,
The handbrake issue is fixed. It was the adjustment of the pads inside the rear disks. An one hour job.

Thanks
