Hi
I have a problem with the handbrake on my evo x. when I engage the handbrake, it locks all four wheels. Does anyone have an idea what the reason could be because I'm already missing it.

I found two trouble code but they don't show up on the dashboard :

U0251

C1290

Abs sensors are ok and the handbrake sensor too. And olso I have evo x rs rear diff and diff pump.


Thanks for help.

 

disconnect the diff pump (just unplug it or remove the relay) and try again...

 

How do you know it locks up all wheels? The parking brake is a mechanical system, a cable that actuates the drum brakes in the rear, not much different than on a bicycle. Should have nothing to do with the fronts.

 

I see how the car behaves and I see that all the wheels stop when I pull handbrake. I guess the braking system itself has nothing to do with it, it's just a matter of the ACD not disconnecting. The same problem is when You have broken handbrake sensor but mine is ok.

I need to check it when I dissconect the diff pump but now I don't have time for my ex.
