Wilwood Plain-Rotor Front Conversion with Red Dynalite Calipers, Hubs and Flexlines for MG TD (1950–1953) and TF (1954–1955)

The red-caliper plain-rotor configuration supplies Dynalite service calipers, iron rotors, adapter plates and aluminum hubs for the specified MG spindles. It is a five-lug disc conversion with included front flexlines, rather than a replacement for the original knock-off wheel interface. The manufacturer, Wilwood Engineering, was founded by Bill Wood in 1977 and is based in Camarillo, California. It designs and manufactures disc systems and component parts across motorsport, street-performance and specialized applications, including calipers, brake rotors, master cylinders, valves, fittings and lines. Those individual parts must be selected in the context of the complete brake system.

Fitment & Compatibility

Match the MG TD/TF application and assess the +0.38-inch outward hub offset on each side. DS1118 requires the original master's internal residual valve to be removed if that single-circuit master is retained. Verify any external residual valves needed for its low mounting and check the wheel-clearance drawing.

Models represented in the detailed applications: TD, TF. Each is subject to its individual year, trim and brake/suspension condition. Use the fitment table below to confirm year, model, trim and brake or suspension options.

DS1118 requires the supplied 0.50-inch wheel spacers to be installed. Their use is mandatory; verify wheel position and clearance with those spacers fitted.

PMB Performance brings over 20 years of parts and fitment experience. Send the vehicle details and installed brake/suspension configuration if you need help checking this package.
