Front hub removal

Re: check the runout

That's good information. Vaguely, as I reflect on it, I think that someone had told me that they were back on the market, but I hadn't seen anything to that effect. I'm glad to see that they're back; they're a good solution to rotor runout correction.

This development also supports what I was told about the "patent rights" problem that had caused SSBC to stop manufacturing and/or selling them. Apparently, the patent owner decided that there was a lot more in the way of application/profit to be made on these things than SSBC was exercising. So, they terminated their agreement with SSBC and set up their own company.

I really think that the inventor of these things did invent them specifically for the Corvette application. However, he must have realized that they had much wider application.

The thing that I don't understand, though, is this: runout is much less of a problem on cars with floating calipers. For the last 25+ years, floating caliper design has been almost universally used by car makers. So, it's hard to see how most shops would ever find the need to use these things for floating caliper vehicles.

rotor runout

I have a colleague with a recent Monte Carlo (2-door FWD) which has rotor run-out issues. This vehicle is included in a TSB recommending these shims as a cure. He encountered these issues when he changed the front bearings. It has the sealed hub sort of bearings which are common on FWD vehicles. He told me that the TIR (Total Indicator Reading) on the front rotor was .005 and it was giving him noticeable pulsation on breaking. I'll ask him what kind of front brakes it has.

Initial contacts indicate that BrakeAlign wants to sell a kit of these shims. It may be difficult to get just one or two shims for an individual vehicle. This could be a good place for a chapter to step up and buy a kit and sell individual shims to its members.
