Hi guys,
Recently replaced front brakes on my L Series wagon, and I discovered a slight noise coming from the drivers side brake shortly after, like a kind of wob wob wob under light braking. Put the front up on jack stands and ran the car at idle speed in 1st gear and discovered I had some serious runout on that disc. Initially I thought I had a badly produced disc but further testing swapping the discs and hubs around has led me to believe the disc hubs themselves are actually worn on the surface that contacts the outer wheel bearing, and this is causing the runout. It actually occurs to a degree on both sides but one of them was bad enough to make noise under brakes.
Does anyone know if its acceptable to machine that surface? I assume a light skim, enough to return the surface true again will resolve it but it would also have the effect of bringing the disc slightly inward. Not sure if that will cause any issues itself? Thoughts?
