Car breaking away

[carlin]

Hi Guys,

Has anyone come across this, when applying the breaks the car pulls to one side, what i mean is turns left or right.
Last night when goin down the straight or round corner, the car wanted break away when applying the breaks.
I'm not sure if it the front end thats the problems or the rear just wondered if anyone new what it could be.

The surface im running on is just carpet

Thanks
