Thread: Electric Parking Brake stuck

Went out the other day and jumped in the MY2014 L494 RRS, pushed the go button, selected R, applied a bit of throttle and no movement. So a bit more throttle and no real movement so hooked into it and back we went ever so slowly. OK I thought, let me try D, maybe it is a bit rusty. Same deal, lots of loud pedal to get it to move, but move it did. And given I was now likely to be late for Drs appointment I decided to push my luck. After a couple of hundred metres it was clear to this old fella that something was really wrong. Back home, left it in the drive and borrowed wife's car.

When I got back, noticed the error message on instrument panel on dash saying " Park Brake requires calibration. Apply foot and park brake. " Unfortunately nothing happened, no noises, nothing. So I called the NRMA. First thing he did was hook up the scanner. Aha, you have a broken hand brake actuator and or control module on the drivers side. When would you like the towie ? I had already checked with my indie who cannot look at it til midweek so it sits in my driveway still. Interesting, in the 10 years since this model came out, he has not seen this problem despite servicing hundreds of them

I have had a look at the workshop manual and followed the instructions to put the system into maintenance mode but that did not work either.

So now it will have to be skull dragged onto the tilt tray unless there is a way to release the hand brake. It is only stuck on the drivers side

Yes, I relise my problems are small compared to others at the moment....


Any ideas ?

Note that with the L494 it has separate electric motor actuators on each back wheel which act on the disc calipers

A new actuator motor for $826 and about half hour labour with a spanner and all is well. It took longer with the computer thingy the mechanic said.

How to complicate a simple funtion !!!
