Look what I got today

[AKbigsub]

Cross over kit, u-bolts, and king pin kits came today. I also replaced the axle u-joints and had the rotors turned. Picked up some new bearings and seals and a tie rod end. I ran all over town and finally found some o-rings for the hubs. I believe I have everything I need to put it together. The only thing needed to get it into the burb is the steering gear. I'll get that next week. Here are some pics:

Doesn't look like you swapped bearing races before having the rotors machined. It's always a good idea to swap the races before machining the rotors (assuming the races are going to be changed) since the bearing races are what is used to center up the rotor for machining. It only takes .006" runout for the rotor to pulsate and cause issues. There is enough error between the race itself and changing them to cause that amount of runout at the rotors edge. Also that rotor on the left in the pic looks like it has chatter marks on it?

No I did not change the races before turning the rotors, nor have I ever. I'm not saying it isn't possible, but in over twenty years in the automotive repair industry I have never seen that cause a pulsation, therefor I never gave it a thaught. But, I will take it under advisement next time.

The marks on the rotors are called a non-directional finish. When turning the rotors, small grooves are present (like on a record) and the brake pads will follow the grooves until they release and "snap back into place. This happens very fast and is one of hte major causes of brake squeeks. The non-directional finish eliminates this condition.

Just wanted to let you know. I'm an automotive machinist and have been doing this professionally for 21 years. I know all about the non-directional finish. The pic wasn't clear enough for me to make that out since it only appeared to be in one area of the rotor.

I am a machinist (non automotive) just wondering how do they make a non directional finish?

Thanks,
Mike

I googled this

I use a free-wheeling disc with a piece of heavy grit sand paper on it (I believe that FMC is where it was bought). After the final cut on the rotor, you press the sand paper against the rotor (while the rotor is still turning) and presto - a non-directional finish.
