BRAKES

BASIC OPERATING PRINCIPLES
Hydraulic systems are used to actuate t he brakes of all modern automobiles.
The system transports the power required to force the frictional surfaces of the
braking system together from the pedal to the individual brake units at each
wheel. A hydraulic system is used for two reasons.
First, fluid under pressure can be carried to all parts of an automobile by small
pipes and flexible hoses without taking up a significant amount of room or
posing routing problems.
Second, a great mechanical advantage can be given to the brake pedal end of
the system, and the foot pressure requi red to actuate the brakes can be
reduced by making the surface area of t he master cylinder pistons smaller than
that of any of the pistons in t he wheel cylinders or calipers.
The master cylinder consists of a flui d reservoir along with a double cylinder
and piston assembly. Double type master cylinders are designed to separate
the front and rear braking systems hydraulic ally in case of a leak. The master
cylinder coverts mechanical motion from t he pedal into hydraulic pressure within
the lines. This pressure is translated back into mechanical motion at th\
e wheels
by either the wheel cylinder (drum brak es) or the caliper (disc brakes).
Steel lines carry the brake fluid to a po int on the vehicle's frame near each of
the vehicle's wheels. The fluid is then ca rried to the calipers and wheel cylinders
by flexible tubes in order to allow for suspension and steering movements.
In drum brake systems, each wheel cylinde r contains two pistons, one at either
end, which push outward in opposite direct ions and force the brake shoe into
contact with the drum.
In disc brake systems, the cylinders ar e part of the calipers. At least one
cylinder in each caliper is used to fo rce the brake pads against the disc.
All pistons employ some type of seal, us ually made of rubber, to minimize fluid
leakage. A rubber dust boot seals the outer end of the cylinder against dust and
dirt. The boot fits around the outer end of the piston on disc brake calipers, and
around the brake actuating rod on wheel cylinders.
The hydraulic system operates as follows : When at rest, the entire system, from
the piston(s) in the master cylinder to t hose in the wheel cylinders or calipers, is
full of brake fluid. Upon app lication of the brake pedal, fluid trapped in front of
the master cylinder piston(s) is forced through the lines to the wheel cylinders.
Here, it forces the pistons outward, in the case of drum brakes, and inward
toward the disc, in the case of disc brakes. The motion of the pistons is
opposed by return springs mounted outside the cylinders in drum brakes, and
by spring seals, in disc brakes.

ARMING SENSOR
The arming sensor is a protective switch
located in the power feed side of the
deployment loop. It is calibrated to clos e at low level velocity changes (lower
than the discriminating sens ors). This assures that the inflator module is
connected directly to the 36 volt output of the DERM or battery voltage feed
when either of the discrim inating sensors close.
DISCRIMINATING SENSORS
The discriminating sensors are wired in parallel on the ground side of the
deployment loop. These sensors are calib rated to close with velocity changes
which are severe enough to warrant deployment.
SIR COIL ASSEMBLY
The SIR coil assembly consists of two cu rrent carrying coils. They are attached
to the steering column and allow rotation of the steering wheel while maintaining
continuous contact of the deployment loop to the inflator module.
INFLATOR MODULES
Each inflator module consists of an inflat able bag and an inflator (a canister of
gas generating material with an initiati ng device). When the vehicle is in a
frontal crash of sufficient force, current flows through the deployment loops.
Current flowing through the initiator ignite s the material in the inflator module.
The gas produced from this reaction rapidly inflates the air bag.
