Abstract: A brake apparatus having a friction pad riveted to a brake shoe and an air conduit recessed within the pad and positioned within its working thickness. As the pad is gradually worn away, the conduit is interrupted by the formation of an opening therein before the rotor can be scored by the rivets. A remote indicator, which may be mounted on the instrument panel of a vehicle, is then responsive to a change in air pressure within the conduit to signal the need for pad replacement.

Abstract: A motor vehicle is provided with a remote battery connector at a location from which its battery terminals are not accessible. The connector includes a single terminal for connection to a jumper cable, the companion jumper cable being connected to the grounded body structure of the vehicle. The remote terminal is enclosed within a mounting box that includes a base and a hinged cover, the cover top being supported in its closed position by a pair of guide walls disposed on opposite sides of the terminal. Securement of the mounting box to the vehicle is by the terminal itself so that installation is quickly and easily accomplished.When the mounting box cover is opened, an illuminated indicia shows the location of the terminal and its proper polarity.

Abstract: A brake apparatus having a friction pad riveted to a brake shoe and a light conductor extending through the pad within its working thickness. As the pad is worn away, the light conductor is severed by the abrasive action of a rotatable member causing a remote indicator, responsive to the interruption of light transmission through the conduit, to signal the need to replace the pad. The configuration of the light conduit insures that the signal will be given at the appropriate time despite misalignment between the pad and the rotatable member.
