CAUTION
The Brake Pressure Reducer (part number 900002)
is required for: 1) all towed vehicles with full-time (‘ac-
tive’) power braking systems; and 2) all towed vehicles
without power brakes —
1) Vehicles with ‘active’ brake systems include sev-
eral hybrid vehicles, such as some models of the Ford
Escape hybrid and the Mercury Mariner hybrid, as well
as the H3 Hummer. These vehicles, and others with
these systems, are designed so that even when the
vehicle is set to ‘tow’ mode, the braking system is still
active, thus requiring minimal pressure to engage the
brakes.
2) BrakeMaster is designed to work with vehicles
that have a power brake system (even though the
power brakes are not activated while towing).
If the Brake Pressure Reducer is not installed in
vehicles with ‘active’ braking systems or in vehicles
that do not have power brakes, BrakeMaster will apply
excessive force to the towed vehicle’s brake pedal,
causing severe tire and/or brake system damage, and/
or other consequential, non-warranty damage.
Step A
Prepare the vehicles for towing
1.
First, connect the tow bar to the motorhome and the
towed vehicle.
Then, according to the manufacturer, make all adjust-
ments necessary to prepare the vehicle for towing.
These adjustments may include: turning the ignition
key to the ‘tow’ position; pulling fuses; disconnecting the
battery; and setting the transmission to a particular gear
or in a particular sequence.
Refer to the owner’s manual or call the dealership for
vehicle-specific information.
CAUTION
To prevent the towed vehicle from rolling, connect
the tow bar to both vehicles before shifting the towed
vehicle’s transmission into the proper gear for tow-
ing.

2.
Make certain that the towed vehicle’s emergency brake
is released.
Failure to release the towed vehicle’s emergency
brake before towing will result in severe brake dam-
age, or a brake system fire. Damage caused by ne-
glecting to release the emergency brake before towing
is not covered under warranty.
Failure to follow these instructions may cause
property damage, personal injury or even death.
3.
Pump the towed vehicle’s brake pedal several times, to
release the stored vacuum in the power brake system.
CAUTION
Always release the stored vacuum in the towed
vehicle’s power brake system before towing — pump
the brake pedal several times.
Depending on the make and model of the towed
vehicle, it may be necessary to pump the brake pedal
repeatedly to release the vacuum.
If the vacuum is not released, the supplemental
braking system will apply excessive braking force
when it is activated, which will cause severe tire and/
or brake system damage to the towed vehicle.
Step B
Attach the pedal clamp and air cylinder
Note: the pedal
clamp will not fit the
brake pedals of a
small number of late-
model Volkswagen
vehicles, such as the
2 0 07 Vo l kswag e n
Golf. A photo of the 2007 Golf brake pedal is shown to
the right.
Use the optional 9329-VW replacement pedal clamp
for these vehicles.
1.
Slide the driver’s seat back, as far as it will go.
2.
Verify that the pedal clamp is right side up, as shown
