Bosch DOT 4 HP is a further development of the Bosch DOT 4 brake fluid and is
characterized by a higher dry and wet boiling point and a lower viscosity. This provides additional protection against the formation of vapor bubbles in the fluid at high
brake temperatures, which can lead to brake failure. ABS/ESP® systems operate more
reliably at low temperatures due to the use of low-viscosity brake fluids. Special additives protect against corrosion in the ABS/ESP® system.
