Ok, so I installed the rear Centramatic balancer ring while I was playing the never ending rear wheel bearing fiasco. Here's a few facts pertinent to the installation.
  • The balancer material is .034" (.8636mm) thick.
  • On a 2018 the clearance requirement for the Rear Speed Sensor Hall Switch to Speed Sensor Ring is .051" (1.2954mm) minimum to .075" (1.905mm) maximum.
  • My original clearance as measured by feeler gauge was .064" (1.6256mm).
  • With the added .034" (.8636mm) balancer ring material, my switch clearance decreased below the minimum to .030" (.762mm). The whole brake disc and sensor ring were displaced outboard by .034" (.8636mm)

So, with all that being said, I had 2 options to rectify the situation.
  • Shim the Speed Sensor Hall Switch out ±.034" (.8636mm) to reestablish the correct clearance and eat the loss at the caliper. (The path I chose).
  • Shim the whole brake caliper out using shim washers to equal .034" (.8636mm) between the caliper bracket and caliper.


Anyone who had done this install, how did you handle the clearances?

As an aside, my bike rides smoother.
