not trying to be rude but... Why are you pulling the handbrake at 5 MPH? You mean 35 MPH trying to do hairpin turns? I am teasing. Expect noise... it's an emergency brake yes, but mainly used for parking, not J Turns and Rallying in stock form. Also it may be your Rear Diff making the noise since you are making the rear end axles lock up in an AWD car.

 

I wasnt driving. I was going in the parking space, the car didnt stop completely then i pull hand brake, that is how i found out the problem,

 

It's not meant for normal stopping. It's called emergency brake for a reason. You are driving into a parking space and can't hit the brake pedal that's meant to stop the car? The emergency brake is just a drum style brake that operates inside the rear brake disc.

Stop pulling your parking brake when the car is in motion...duh.

 

Im not doing any crazy turn. Im just asking is any having the same noise. Or it is nornal for this car. I tested on my e46 m3, it doesnt have any noise like that.

 

Uploaded a video to show the sound from pulling the brake.2015 wrx sti - YouTube

 

My car has a similar problem. When I'm pulling into a parking spot and throw it into reverse, it makes a horrible grinding noise.

 

It is a normal noise, it is not a problem.

 

Not sure why OP got slammed on this. Any car should allow its driver to use the e-brake for whatever reason in motion or not. E-brake is NOT designed to use only for parking!!

OP, my STI or any of my other cars don't make that sound when pulling the e-brake lever, whether the car is in motion or not.

I'd say getting your car check out, be sure to tell the dealership that you're testing the car in case of emergency like when there is a brake failure in the future.

From what I understand, the center diff on the STI is supposed to disengage when hand-brake is pulled.

To the people that bashed OP, please enjoy your car and stop being such a sissy

 

Thank you, i will let the the dealer know

 

Yea something about that sound definitely ain't right.

 

2015 STi Launch Edition here, same noise. My FR-S did the same thing too. It's more likely due to the fact that it's a drum brake. I wouldn't worry about it too much.

 

Yes, mine is Launch Edition too
