    Overall Assessment

    Customers highly value the product for its impeccable fitting on Afco 2-3/4" piston metric calipers, highlighting its precise manufacturing. It displays reliable functionality, although it does not fit smaller piston sizes or factory metric calipers. In comparison to other products, it manifests superiority in usability and sizing, with recommendations for the addition of 1/4" and 1/2" sizes to cater for a big caliper/thin rotor combination. Our product's quality and practicality, according to reviews, set it apart from competitors.

    Worked great but would be nice to have 1/4" and 1/2" sizes that you could combine on a big caliper/thin Rotor Combination
