Introduction
Congratulations you now own the cleanest, most efcient and user-friendly brake uid service machine available
today. Your new electric pressure brake bleeder is designed specically for modern hydraulic brake and clutch
systems. It is advised that only professional technicians perform brake system service.
The MotorVac BRAKEVAC-II equipment has been designed for use on all hydraulic brake and clutch systems
especially Anti-Lock Braking Systems. The simplicity of our pressure bleeder makes it very user friendly and eliminates the need for hands-on training.
The large capacity reservoir allows for a single service on any vehicle. The uid should be drained and kept in a
sealed container between vehicle services as the onboard storage is not air-tight.
The MotorVac BRAKEVAC-II System allows years of clean, safe, one-man operation brake services.
Thank you for choosing MotorVac.
Sincerely,
The MotorVac Team.

Why should the Brake system be Flushed?
Brake uid is hygroscopic meaning it can absorb moisture from the air resulting in a dangerous reduction
of its boiling point. Water contaminated brake uid under repeated working pressure boils and creates air
bubbles. Under severe conditions, this can result in complete brake system failure.
Water contaminated brake uid causes electrolysis to occur inside the brake system. The oxygen contained
in the water droplets cause oxidation. Electrolysis and oxidation corrodes the hydraulic master cylinder and
wheel cylinders, and steel brake lines from the inside. Pressure bleeding has been proven the most effective
method in ushing and bleeding hydraulic brake systems. Flushing the brake system and replacing the dirty
and contaminated brake uid with fresh brake uid can often avoid expensive repairs.
