NOTE
Refers to important information and is placed in italic
type. It is recommended that you take special notice
of these items.

Before you begin the installation…

This is a replacement for the proportioning valve in
BrakeMaster model 9060 systems.
These instructions assume that all other BrakeMas­ter components are installed, and that you will con­nect the replacement proportioning valve at the same
location as the original. (If you will not connect the
replacement valve at the same location, do not use
these instructions. You must use the original Brake­Master 9060 installation instructions, available at www.
roadmasterinc.com under ‘Support.')
Additional components, not supplied with the valve,
are necessary. See step 2, below.

These instructions pertain to the initial instal-

lation of the proportioning valve and associated
components only. Operating instructions are con­tained in the owner’s manual.
Read all instructions before installing or operat­ing the BrakeMaster system. Failure to understand
how to install or operate BrakeMaster could re­sult in property damage, personal injury or even
death.

(including the two compression nuts, ferrules and brass
inserts — see Figure 3);

• the 3/8" nuts and bolts used to attach the propor­tioning valve to the frame of the motorhome;

• the brake line tee and the section of brake line at­tached to it;

• the brake line flair adaptor (if used); and

• the metric-to-standard brake line converter (if
used).

2. In addition to the components above, you will also
need —

• a ¼" rubber brake line plug; and

• a 12-10 gauge (yellow) butt connector if the motor­home has separate brake and turn signals or a 16­14 gauge (blue) butt connector if the motorhome has
combined brake and turn signals.

1. Do not discard any of the components that were
attached to the valve; they will be used with the re­placement valve. These components include —

• all wiring connected to the proportioning valve;

• the air lines connected to the proportioning valve

Install the proportioning valve

If the motorhome is raised at any time dur­ing the installation, it must be on a hoist. If you
will work under the motorhome without it being
raised, it must be safely and securely supported
and blocked.
If the motorhome is equipped with an air suspen­sion system and a line to the air suspension system
is inadvertently opened, or if the motorhome’s air
suspension system is turned off, the motorhome
will lower to the ground.
The motorhome may unexpectedly roll forward
or backward, especially if it is on an incline, if it
is not blocked.
Failure to follow these instructions may cause
property damage, personal injury or even death.

1. Disconnect the air lines and wiring from the original
proportioning valve.
Note: the “in” and “out” air lines (attached at the

fittings shown in Figure 2) are identical. Mark or oth­erwise identify them before disconnecting them — the
supplemental braking system will not work if the air
lines are reattached to the wrong fittings.
Note: there are two wires extending from the sole­noid valve (Figure 1). One is connected to ground; the
other to the brake light wire. Disconnect the ground
wire. Remove the butt connector from the brake light
wire and discard the butt connector, noting whether it
is a 16-14 gauge (blue) or 12-10 (yellow) connector.

Position a pan or bucket under the fitting attaching
the section of brake line to the port (Figure 1) to catch
any brake fluid. Unscrew the fitting.

Plug the line with a ¼” rubber brake line plug (not
included) to prevent any further loss of brake fluid.

2. Remove the master cylinder reservoir cover and, if
necessary, fill the reservoir with brake fluid, up to the
maximum marking. Reattach the cover.

Wear appropriate eye protection when work­ing on the brake system. If brake fluid comes into
contact with your eyes, follow the manufacturer’s
