Brake pad not contacting whole disc face

(1/5) > >>

grifter:
Any idea why brake pad is no rubbing on whole disc face.

I've just renewed pads/discs and checked sliders were all ok, not seized or sticking, cleaned the whole calipers etc.



Strange how a pad could contact just over half the disc!

The rust spots are just where rain got in the wheels

johnnydog:
Until a new pad wears to the profile of a new disc, it isn't unusual to have partial contact of the pad against the disc face for the first couple of hundred miles or so. I am certain that in the next few hundred miles of use, you will have a nice shiney disc across the whole area as the material of the pad wears slightly to match the disc profile.

johnnydog:
That picture also highlights why coated discs are beneficial over non coated - if only to avoid the  premature rusting on the centre hub area and extreme edges of the discs after only a few days / miles.. :y

Doctor Gollum:
Are the discs/pads correct for the car?

3.2 v6, but 2.6 should be IDENTICAL.

Discs should be 296x28. Calipers and pads shouldlook like above.  :y
