A DEVICE FOR MEASURING THE THICKNESS OF AUTOMOTIVE DISC BRAKE ROTORS

摘要

A vernier calliper for measuring the thickness of a disc brake rotor fitted to a vehicle, the vernier calliper including:(i) first and second members which are mounted for sliding movement relative to one another along an axis;(ii) first and second abutments located on the first and second members respectively and being adapted, in use, to engage first and second sides of a disc brake rotor, the first abutment including an abutment surface;(iii) retaining means for retaining the calliper in an operative position in which:(iv) the first abutment surface engages the first side of the disc and is parallel thereof;(v) the second abutment engages the second side of the disc; and(vi) said axis is orthogonal to said first and second sides of the disc.
