The day after new front brake disks were fitted, I feel vibrations in the steering from around 65mph. I am definitely sure of that since I drive motorway every day. Is there any way you can balance the brake disks, do they need balancing? The disks are original Saab parts.
I doubt that they're out of balance, all it takes is a flake of rust left on the hub to cause run-out.
Does this mean that discs have to be re-fitted?
Yes. Assuming there's some run out.
