B&M 46076 LAUNCH CONTROL KIT - Manual

This Launch Control must be
installed according to these
instructions for safe operation. The
unit can be used in either the front
wheel part of the brake system or the
rear wheel part of the brake system
of a passenger car or light duty truck.
Install the launch control in the rear
brake system only for use as a hill
holder system on the street.
The B&M Launch Control is a
standard design with one connection
from the master cylinder and one
connection to the brakes.
WARNING: The B&M Launch
Control is designed primarily for use
on high performance vehicles used in
drag racing. It is for short term use
(60 seconds maximum) to lock the
wheels while staging the vehicle for
drag racing. It is not intended for use
as a long term brake holding device.
It should only be used on passenger
cars and light trucks (3/4 ton or less)
using a standard hydraulic brake
system that is in good safe operating
condition. If your vehicle is equipped
with a dual diagonal braking system
(the left front is connected to the
right rear and the right front is
connected to the left rear; common
to front drive imports), two launch
controls must be utilized. The B&M
Launch Control should never be used
as a temporary brake holding device
in place of a parking brake or in place
of a driver depressing the brake pedal.
IMPORTANT: Read and fully
understand these instructions before
installing the B&M Launch Control.
Note that these instructions contain
warnings that must be observed in
order to reduce the risk of improper
installation that could make the
vehicle unsafe and result in possible
serious injury. If you are not
experienced or qualified at doing this
type of installation, we strongly
recommend that you have the B&M
Launch Control installed by a qualified
and certified automotive mechanic.
Do not cut or attempt to flare steel
tubing. Do not use copper tubing. Use
a tube bender when bending the
tubing to avoid crushing the tube. Pre
assembled steel braided BRAKE
hoses may be an acceptable
substitute for steel lines in high
performance applications.
INSTALLATION NOTES
On rear wheel drive applications, the
solenoid valve can be installed in the
front wheel brake system as a staging
device for drag racing and in the rear
wheel brake system for short term use
as a hill holder (60 seconds
maximum). On front wheel drive
applications, the solenoid valve(s)
should be mounted in the rear braking
system(s) for use either as a staging
device or hill-holder (60 seconds
maximum), The solenoid valve does
not interfere with normal operation of
the brakes or with safety regulations
when installed according to these
instructions.
The brake light system on the rear
of the vehicle must operate when any
part of the brake system is
pressurized. A hydraulic pressure
brake light switch must be installed in
the system if the launch control valve
defeats the operation of the stock
brake light switch. See the electrical
section for details.
The launch control valve must be
mounted to a rigid surface to prevent
vibrations that could cause failures of
the joints or lines· The firewall is a
good mounting location. Keep the
valve and the brake lines away from
the heat of the exhaust system.
Two basic types of master
cylinders have been used on
production cars, single master
cylinder and dual master cylinder·
Dual master cylinders have been
required on all production cars built
since approximately 1970, earlier cars
have single master cylinders. The dual
master cylinders have the brake fluid
reservoir divided into two separate
sections while single master cylinders
have a single compartment reservoir.
SOME CARS (MOSTLY FRONT
WHEEL DRIVE) HAVE
DIAGONALLY SPLIT SYSTEMS
