[boeing]

Hi all would like your thoughts on this one
X5 07 while braking at around 120 kmh and decreasing through 80 kmh the wheel starts a slight shudðer and then eventually stops I have beaked hard now an again incase it was uneven pads but it seems to be continuing ?

warped rotors,

Ok warped rotors so I guess that would require new rotors , is that a big job ?

These are on ebay, stick with oem and new pads too. U may be able to have the rotors machined if they are pretty new.

Thanks for all your help turned out to be a lip on worn brake disc , new ones fitted and all good.

Thanks for updating the post, very useful.

Please explain though, concave lip, replacement rotor?

Yes lip on worn rotor so replaced both front rotors.

I'm assuming it was something like this:



Such a lip/edge can cause a shudder as the pads have a little freeplay.

That's what it looked like thanks
