The buggy is on all 4’s finally! This week end I installed the loaded corvette calipers onto my welded on “horse shoe brackets” from WEPS. I should also say that I bought the 8 lug flanges from WEPS and welded them onto my machined, stock 404 hubs. I have nothing bad to say about the WEPS products.

The issue I have is, when I put on the tire and rotated it, it spins freely half of the time and the other half it grabs and take a bit of force to get it through the cycle.

My question is how common is this and how much of this “grabbing” is acceptable? I imagine I will get some brake pulsation?

Any of you dealt with the same issue?

you may be experiencing some 'runout' from the rotor. I had one wheel that did this:mad3: but after I ran it for a while,it 'seated in' or clearanced itself, and I had forgot about it until reading your post.

I wonder if somehow my hub flange got warped during welding? We mig’d them and tacked all around before the final weld. It looks like at the worst point I am 3/32” out of true (measuring from the top of the rotor to the face of the portal box). Or maybe the rotors are out a but?

WEPS- did you have some nasty brake pulsation?

What do you mean by "runout"

I believe he means that your rotor is not completely true to the flange and may simply be mis-cast or that your flange is not true to the spindle.

In either case it is largely irrelevant. If your tire does not wander too badly going down the road I would try and find a shop that has one of those on the car style brake lathes and simply have them turned in place until they are 'right enough'.

That is not a bad idea! I was thinking about trearing everythng apart and starting over but that would be a ton of work.

I am going to call a couple places today to see what they would charge. Thanks for the comment.

I would not do that. Then your stuck with that specific rotor in that specifc spot on the hub. You ever take that rotor off or have to replace it, you'll have to do it all over again. Mic the hub and at least see if that is it first.

If it was me I would run it as is with the truing and then when/if you replace the rotor simply have the hub flange trued at that time. Unless you are just trying to have a bunch of unnecessary down time.

After this issue has ruined my week I have come to the conclusion that I am just going to run them as is. I am sure I will have some brake pulsation, but at medium to low speed I should be OK. I wish I thought about turning the hubs before all of this, but live and learn. I understand that some of the “run out” could go away with a bit of use.

Late reply- but I did have some pulsation, but it went away over time.Most times when I do the hubs for others I do not reface the mounting surface. I clamp/tack in place just as you described.
...But my rig is a trail rig only...

i had the same problem all i did was put the hub only on a brake lathe and a couple of passes and the hub was true. worked great dont have to worry about indexibg the rotor or anything. cheers chris

I may do the same thing if the problem is very bad. Way it hard to find a place to turn them?
