2-2 Total Brake Failure

Loss Of Fluid/Brake Line Abrasion

Triumph TR4/TR4A Models

Owners of the above models should check that the chassis-to-engine electrical grounding strap, adjacent to the left engine mount, is not in contact with the steel brake line feeding the left front wheel. Due to movement of this strap from engine vibration, the steel brake line can abrade and wear to the point of rupture under hard braking or result in brake fluid loss. In both cases, total brake system failure can result.
