Bridgeport 12180073 Brake Shoe Set Milling Machine

Product Description

The BRIDGEPORT 12180073 is a 2-piece brake shoe set designed as a direct replacement component for Bridgeport milling machines. Brake shoes in a milling machine spindle head provide the friction interface that engages the braking mechanism, allowing the operator to stop spindle rotation quickly and hold position. This set is a service part installed during routine maintenance or when existing brake shoes show wear, glazing, or reduced braking effectiveness. Installation is performed by qualified machine tool technicians or millwrights familiar with Bridgeport head service procedures.

This brake shoe set is specified for use with the 2J-Head Top Housing on I Series Bridgeport milling machines. It is suited to machine shops, toolrooms, and production environments where Bridgeport knee mills are in regular service. Replacing worn brake shoes restores proper spindle braking response and reduces wear on adjacent head components. This is a stocking service part intended to support scheduled maintenance programs and unplanned downtime repair situations.

Installation Notes

Brake shoe replacement on a Bridgeport milling machine head should be performed by a qualified machine tool technician or millwright.

Follow the head disassembly sequence outlined in the applicable Bridgeport service manual to avoid damage to the quill, drawbar, or surrounding head components. Do not operate the machine with partially seated or improperly aligned brake shoes.
