Nice Ride

Curious.... Did an Oil change today and noticed both Rotors on the inside had all Vent Holes clogged. Outside were clean / open ....

Anyone have comments... Is it normal for the drilled holes to fill up with caked brake pad? I noticed its blocked on both front interior rotors... Is this caused by bad pads? It sort of defeats the purpose of having the holes....

It doesn't matter...

Check out this video:

Don't think it's caked brake pad

Your car new, used, etc?

Signs of this stuff anywhere else on the undercarriage?

I didn't watch the nerd I the video, but this seems normal.

38K on it. Weekend driver. Not sure what you mean by on the undercarriage.. What I do know that right after I detail the Rims, one drive and the Rims are Dusted with Brake Dust. I found that if I drive the car right after washing it, the rotors spin out the remaining water with all the brake dust mixed in. If I let the rotors dry after detailing, no mucky mess on the inside of the rims, just the normal heavy dusting on the rims....

get low dust pads see if that helps

You run OEM pads or a particular brand...

That is brake dust and it is 100% normal.

Thanks for the feedback!!! Strange that the exterior of the Rotor holes are mostly clear, but the interior are for sure blocked.

I wonder how many OCD people like me are now checking the vent holes...

I plan on doing brakes and rotors within the next month or so.
