Mercedes ML430 Brake Pads

Lets face it - you are going to have a real screamer there! Have they put copper putty or paste or goo of some sort on the back of the pads when they mount them? It makes them slip quietly or something. Or it could just be that your ML430 is too old and can't take the hard use you are subjecting it to. Try dragging your feet to stop it, or let it gently run into a tree or maybe some lesser vehicles along the kerb next time you want to stop it.

Hi,

I have owned an ML320 and ML350. Both have had this problem.

ML320: Very bad squeal on front wheels only. Fixed by replacing pads.

ML350: Minor problem which came and went from time to time. Then suddenly it got very bad. Bit the bullet and asked for a service... M/B replaced the disks at no cost. I had to pay for the pads.

General: M/B garage told me that this is a general problem with ML disks/pads. Made worse by using acid based alloy clearers on the wheels. The new disks look totally different to my un-educated eye. Thicker and without machining marks. Watch out for rust on the set screws that hold the disk pad unit on; they will rust quickly after the nice silver/grey paint has been damaged.

HTH.

It's not the pads it's how you mount them. there are lots of different "anti-squeal" products. Pick one.
