What's the purpose of the brake surround thingys (insert proper name here) - the large plate on the inner side of the front disc brakes on a Sierra?


Are they just for protection or do they serve a purpose I'm not aware of?

Pretty sure they do act as a sort of water splash guard when driving on road.

I thought they were to 'protect' the rotor from stone damage and prevent stones/tar getting into
the pads. Most people take them off to let mud/water out quicker.

They also retain the bearing don't they?

The backing plate only retains bearings (among other things) on the rear drumbrakes.

The backing plate on the front discs does nothing but deflect stones n shit, make nice squealing noises when stones get stuck behind it, and it also collects mud behind the flange so the mud can eat away at the hub seal.

I missed the "front" part...

I have no front plates.

And my rears are modded to get the axle out without removing brakes.

they are a stond guard and also aid in keeping the rotors at operating temp.
