Locked wheels...nooooooooo!
Hi all,
Preface: swapped out winter wheels and tire set up for summer the other day. Then this happened...
Once I was done I realised the parking brake was locked on, car wouldn't budge. I engaged and disengaged the manual switch multie times. Turned the car on/off. Tried with door closed and seat belt on. I CANNOT get the brake to release. The indicator light goes off and on and the brake pedal moves normally as the parking brake is applied and released but the car lurches and ECU cuts throttle to avoid damage to brake components.
I've searched high and low on the interwebs and nada.
Anyone ever had this issue? Recommended solutions?
Thx

my wild guess is that your winter wheels may have required longer lug bolts? ..... but after switching back to your
summer wheels (which have thinner cross section) the longer bolts were too long...or just enough to prevent the
wheel from turning as they've impacted something back around the hub. but that wouldn't make sense if you
were the one who installed the winter wheels and would have known of the lug bolt length differences, yes?
are these the same lugs you have used previously for both winter and summer wheels ?

Thought of that..

I also thought of putting the stock wheels back on to see if it was wheel related and no dice. The car is now inoperable regardless of wheels and tires. Argh. Very frustrating.
I am thinking it had something to do with the car being lifted. Was thinking of removing the actuator to get it to the dealership.....

SOLVED!!
Look closely at the shiny spot on the knuckle. This is what metal on metal does Could have been much worse....
Soooooo, after much investigation I realised that one of the wheels had an incorrect offset and didn't have clearance past The knuckle. I cracked a wheel last summer and purchased a replacement wheel but never mounted it because it was a summer wheel and tire and it was November. Apparently the place that sold me the replacement wheel ordered and delivered the wrong wheel and I didn't find out until now. No major damage, thank the lord and disaster averted.
Operator oversight ....... doh!!!! Just goes to show you gotta doubke check everything for yourself.
