Wheel Brake Caliper Clearance Diagram - A, B & C Radius Measurement Blueprint

This document is a blueprint-style cross-section drawing of a wheel used to illustrate brake caliper clearance. The drawing shows the wheel's rim and center section in cutaway, with a stepped shaded template representing the space a brake caliper occupies behind the wheel face. Three dimensions are called out: "A", a vertical height measured near the wheel's mounting face; "B" RADIUS, measured horizontally from the wheel centerline to the inner step of the clearance profile; and "C" RADIUS, measured from the centerline to the outer step of the profile. The drawing contains no numeric values, tolerances, part numbers, or vehicle/year identification, it serves as a reference diagram defining where the A, B, and C caliper-clearance measurements are taken on a wheel cross-section. Readers can learn how wheel-to-caliper clearance is specified using these three dimensions, which is useful when checking whether a given wheel will clear larger brake calipers (such as during a brake upgrade). The actual clearance values would need to come from an accompanying specification table or by measuring the wheel and caliper in question; this page only defines the measurement locations.
