Review on 🔧 Enhance Your Braking Precision with Shimano F180P/P2 Disc Brake Adapter by Ricardo Stewart

Shimano does not offer the best recommendations for using this adapter. For my frame mounted rear caliper I used this adapter (F180P/P2) to increase the rear rotor size from 160mm to 180mm. The instructions that came with the adapter only show front fork mounting and not rear "frame" mounting, but I have included a photo of the adapter mounting. Please note that the conical discs are placed on the brake caliper. Installation went smoothly. The pads wrap around the rotor in the right place. Simply align all the parts and install by loosening the caliper bolts slightly so that the caliper barely moves. Firmly pull the brake lever to clamp the caliper pads onto the brake disc and align the brake pads with the surface of the brake disc. Tighten the caliper bolts without removing the lever. Then tighten the bolts to specification.
