Brake shutter

[Mince]

Hi guys started getting this funny issue.
At round about 80km/h when u brake u get this faint shutter if you go over a hundred and brake the shutter is hectic what could it be i know the discs in front are new so they cant be warped any advice?

Rear disks?
When was the front disks changed?

I got the car about 6 months ago they were changed then the rear im not sure about

Hmmm can you feel the shudder in the steering? Or is it felt through the car and not the steering?

 

[Mince]

I would say both hey

Sounds like front discs then :hammerhead: if you close to midrand can have a look at it and possibly advise on what you should do :=):

possiblities ?
1) Pads and disks were not "run in" correctly, when the new disks and pads were fitted, and the disks are now glazed
2) Inferior pads or inferior disks
3) Disk became (DTV) warped due to rapid heat and rapid cooling taking place in short time space (DVT = Disk thickness variance, similar to the way the tar gets bunched into a hump at traffic lights)
4) Suspension components worn

as Ralf said if the brakes are good check suspension. mine was lower control arm bushes

And if it's the disks, don't bother skimming, it's just going to be a waste of time and money.
