Upgraded stability means enhanced stopping effectiveness compared to competitive 23,000 lb. entry-level linings.

Engineered for consistent recovery after “shock stops” are experienced, which enhances stopping and wear performance over a longer life cycle.

Lining wear rate performance at low-to-moderate temperatures improves the value proposition vs. other entry-level linings.

Unaggressive friction nature extends brake drum life.

Brake chamber pressure [psi]

• All brake linings get “shocked” when subjected to a prolonged, elevated temperature event, such as braking while coming down a long, steep grade with a heavy load.

• The overall stability of the lining formulation is what makes the real difference when comparing pre-shock and post-shock braking performance.

• Post-shock stopping effectiveness can be reduced as much as 30%, on every post-shock brake application, in linings with a weak stability rating.

• HV88 is engineered to be a more stable lining than typical low-cost alternatives as offered by many competitors.

• HV88 formulation specifications are focused on a tight pre-shock and post-shock performance band which delivers better stopping effectiveness and lower wear.
