Is there any difference between the two handbrake options?

I notice that, on Xbox at least, both RB and A are assigned to handbrake. I had a look at the controls and noticed that A is also used for answering the phone in the vehicle, so my question: is there any difference between the two handbrakes? I know on a bike there is additional braking controls (different buttons for front and back brakes) but presumably this is not the case in a car.

Solution 1:

According to the manual, there is no difference.

A and RB buttons are both mapped to the handbrake, so it's just for convenience.

Personally, I alternate between the two based on what I am doing.

Example:

When I want to change weapons, X, and make an immediate sharp turn, I would use A.

Otherwise, I would use RB (especially if I had to answer the phone).

Hope this helps!
