Solving Pad Knockback

[Vegas69]

Here are two videos I did over a year ago. This was with the thin retainers that came with the kit and roller bearings. The problem was the retainers had no preload on the axle bearing. In fact there was a small gap between teh bearing race and retaining clip. That's when I contacted Wilwood and they started working on a fix. Unfortunately that meant I had to purchase Currie plates and pay to have my bearing pressed off and on.In fact I paid for new bearings as well. That change did cure the no pre load issue and retainer flex, but it didn't totally solve the problem. I'd say cut it in half.

Next I switched to tapered bearing axles from moser. At that time Wilwood had came out with the updated retainer so I used it and found that the pre load machined into the surface was identical to the Currie plates. So I used the wilwood plate to keep from needing to press bearings off and on. This didn't totally cure it either. It did cut it in half again.

I just switched to a 1" bore master to attemp to make up for some of the rest by providing more volume. I haven't driven the car but will this weekend. At this point I feel it's a combination of axle flange and bearing flex. I have 33 spline axles. Part of me wonders if the deep dish wheel and parking brake rotor offset effects it as well. Bottom line is I hope the 1" bore makes it decent until Wilwood comes out with a floating caliper or rotor. That's the real fix in my opinion.
