Hi guys. In need of Abit advice? Sorry if it's a stupid question? When I brake my steering shakes? What can be the issue? And I'm aware the tracking aliment is slightly out, can that be the issue?. Thanks

It could be caused by a warped disc/s.

Most common cause the sliding caliper don't slide anymore you will have to remove the slide pins clean and re=grease them (silicn or rubber based grease) replace the pads and the discs that will sort this out
