I'm pretty positive it was 3 or 4 but I could be wrong. I just don't remember man. I stuck dot3 in it this time.

 

Not usually -- sounds like a warped rotor. Since it's sticking, you might have overheated and warped it.


I absolutely wouldn't mix the glycol based fluids with the silicone based ones. That's probably what happened. If they were used and not rebuilt ones, then it may not even have been you who mixed them.

 

They were new refurbished, bought them from carquest.

As far as the rotor, if it was warped wouldn't I get a wobble at higher speeds? I travel at 65-75 regularly and I've never had that issue.

 

If its only slightly warped, you'll get a slight pulsing of breaking and only under very light breaking. When driving or braking more normally, you'll never feel it. However, it'll do as you observed -- spin freely over some parts of the rotation and seem to bind a little under others.
At least, that's been my experience. I don't drive in a lot of busy traffic, and have a tendency to brake very lightly a lot of the time, so I find myself noticing such things.


When I had a front wheel bearing eat itself on the Mercedes, I never noticed any difference in braking behavior, even with my light foot. Then again, I noticed and fixed it before it ever did much more than make noise.

 

I put a LOT of miles on the truck in a lot of different conditions. But I've never felt a wobble at all. It just wants to pull to the left for some reason.
