Steering wheel vibrates when braking

[Flying Scotsman]

Hi
Appreciate any suggestions as to why my steering wheel shakes when braking. Shakes more violently if braking from higher speed but shakes to a degree at any speed when braking.
Ssv 2015. Everything stock. Owned from new. Only 15000kms from new. No track work or ridiculous (!) driving. I know brakes, pads, rotors are 'consumables' but due to low kms I will be pushing for it to be rectified under the 5 yr Holden warranty. Just chasing any ideas, opinions, advice before I take it back to the dealer who sold it to me new and has done all servicing to date.
Many thanks all.

Most likely needs new front rotors....
Sounds like warped rotors....

Thanks Ron.
Any idea why rotors would be warped after such low kms? Reckon it could be considered as warranty issue?

 

[Ron Burgundy]

Given low ks most likely just a result of uneven wear...
I doubt holden would cover it under warranty but worth trying...

How long has it been doing the 'shakes'?

How long has it been doing the 'shakes

Noticed it the last couple of weeks. It's not my daily drive. A couple of weeks ago it was very noticeable when I braked hard from about 110 kph and I've noticed it since then braking at any speed. But less noticeable when braking at lower speeds around town. Was going to wait until next service in July but thinking better to get it investigated before then. Not sure why the rotors might have damaged by uneven wear. What causes uneven wear?

Inspect the front rotors, look for a 'weird' pattern on the friction faces.
They might be dodgy castings, or it might have a transfer of pad material unevenly around the rotors.

Rotors can warp due to sudden cooling. e.g. going through water when they are hot - or even the car wash. I'm pretty sure the warranty won't cover that.

Is it worth doing the bed in process again?

If it’s unevenly transferee pad material doing the bed in process could help.

No point of that....
