Thank You for Your Interest in TSM.

TSM has been in business since 1982. We manufacture Rear Disc Brake Conversions for most rear drive vehicles. Also available are drive shaft parking brakes. We can supply everything from the basic conversion kit through the calipers with or without the parking brake. We also have braided stainless, or rubber brake lines.
