7.0 EQUIPMENT DESCRIPTION

7.1 BRAKE ASSEMBLY

The brake is a single fixed cylinder, 5 piston, hydraulically operated, internal dual floating disc
design. It is suitable for use with brake fluid conforming to MIL-H-5606, designed to withstand
a 1000 psi maximum operating pressure, with zero psi back pressure.

7.1.1 Brake Operation

By depressing foot pedals, the aircraft master cylinders deliver hydraulic pressure to
actuate the brake assemblies. Under pressure, pistons in the cylinder compress the
brake stack, there by developing the braking action. When the foot pedals are
released, the hydraulic pressure is relieved and the brake stack returns to normal
position.

NOTE: Due to the pressure head in the hydraulic system, the brake will exhibit a light
dragging with brakes off. This condition is normal and is not detrimental to tire
or lining life.

7.2 WHEEL ASSEMBLY

The wheel is forged aluminum and conforms to all tire and rim association standards for a
6.50-10, Type III divided type wheel. It is a tubeless / tube-type design and incorporates an
O-ring seal. The wheel incorporates inboard and outboard halves which are fastened
together with bolts, washers, and nuts. The brake disc is attached to the wheel by the bolts.
The wheel rotates on two tapered roller bearings, which seat in bearing cups in the wheel half
hubs. Rubber lip grease seals provide protection and lubricant retention for the bearing.

8.0 KIT INSTALLATION

SAFETY WARNING: INSURE AIRCRAFT IS SECURE AND STABLE BEFORE

BEGINNING ANY WORK. WORKING UNDER AN
IMPROPERLY STABILIZED AIRCRAFT COULD CAUSE
INJURY OR DEATH.

8.1 REMOVE EXISTING EQUIPMENT (Refer to Installation Drawing 50-90)

a. Jack aircraft in accordance with Beech Service Manual. Deflate main wheel completely,

3) Install new bracket, P/N 139-19100, Item 9, on the brake, using the five (5) back plate
bolts, Item 24, with washer, Item 25, between the bracket and cylinder as shown per
View E.

4) Repeat steps 2) & 3) above for the second brake, and then install the Brake Deice
Manifold to this brake only, using existing attachment bolts, washers, and nuts.

5) Upon installation of brakes to aircraft, assure that the bracket on the opposite brake
and manifold line up properly. Then attach manifold to brake with existing bolts, nuts,
and washers.

NOTE: Only twelve (12) bolts, nuts, and washers are used per manifold. The four (4)
upper most attachment points are eliminated for this installation.

b. Mount inlet fittings of the Swivel Kit (Beech P/N 99-8003-27) to appropriate port of the
cylinder assembly of each brake.

NOTE: The brakes are nonhanded. The plug, item 21 and inlet fitting may be exchanged
as needed for alignment with the inlet swivel.
c. Mount one brake assembly, Item 2, on the axle, making sure that the brake cylinder
bottoms on the strut, and that the torque ring, Item 28, engages the gear lug.

d. Connect the inlet swivel to the brake that has just been installed. Install the other brake in
place on the axle, making sure that the brake cylinder bottoms on the strut and the torque
plate engages the gear lug, while assuring that the brake inlet fitting aligns and connects
to the inlet swivel previously installed on the opposite brake.

washers, Item 5. Torque these bolts to 150 in-lbs.

f. Unplug the lower hydraulic line and reattach to the inlet swivel fitting.

g. If the aircraft has de-ice, wait until the aircraft is lowered off the jacks,and then re-attach
the brake de-ice hose assembly.

h. The wheel assemblies are shipped from the factory as a complete assembly. The
bearings are packed with grease and installed in the wheel halves.

NOTE: Extended storage of lubricated bearings may require re-lubrication.

i. Remove snap ring, Item 16, grease seal, Item 15, and bearing cone, Item 20 from the
outboard side of the wheel assembly, and place on a clean surface to avoid
contamination.

j. Separate the wheel halves by removing nuts, Item 14, washers, Item 12, washers, Item
13, and tie bolts, Item 11.

k. Position outer wheel half assembly, item 17, on a flat surface with the register side facing
up.

l. Place a serviceable tire over outer wheel half, and install tube in tire if applicable.

m. Lubricate O-ring seal, Item 19, with Dow Corning Molycote 55M grease (or equivalent),
and position on register portion of inner wheel half assembly, item 18.

CAUTION: SEAL SHOULD NOT BE TWISTED, BUT FULLY ALIGNED IN GROOVE.

n. Place inner wheel half, in tire making sure to properly align inner and outer registers on
wheel as well as valve stem on tube if applicable.

CAUTION: DO NOT ALLOW THE RESERVOIR TO BECOME EMPTY DURING

BLEEDING.

8.4 BRAKE LINING CONDITIONING

When new linings are installed, it is important to condition them properly to obtain the service
life designed into them. Condition linings as follows:.

8.4.2 Perform two (2) full stop braking applications from 30 to 35 knots, allowing the brake
discs to cool between each stop.

8.4.2 This conditioning procedure will wear off high spots and generate sufficient heat to
glaze the lining. Once the lining is glazed, the braking system will provide many hours
of maintenance free service.

8.4.3 Avoid light use, such as taxiing, which will cause the glaze to be worn rapidly

CM30-162 COMPONENT MAINTENANCE MANUAL WITH IPL

FOR MAIN BRAKE ASSEMBLY PART NO. 30-162

DESCRIPTION AND OPERATION

1. Main Brake Description

The main brake assembly is a piston actuated, hydraulically operated, internal dual floating disc
unit that is designed to be compatible with MIL-H-5606 hydraulic fluid. The brake assembly is a
nonhanded unit and can be used on the opposite side of the aircraft by simply switching the
plug fitting (110) and a preformed packing (115) on top of the brake cylinder to the opposite
port.
Each brake assembly is composed of the following: One brake cylinder, one pressure plate
assembly with replaceable steel wear pads, two rotating discs with sintered friction material on
a steel core, one center stator with sintered friction material on a steel core, one backplate
assembly with replaceable steel wear pads and, five high strength bolts and washers.
Each of the five pistons contains an installed O-ring to prevent leakage of hydraulic fluid past
the pistons.
A piston insulator slides into the pocket of each piston in order to shield the brake fluid from the
heat generated during braking.

DESCRIPTION AND OPERATION

2. Main Brake Operation

Braking action begins to occur when hydraulic pressure is applied to the brake, via the pilot’s or
copilot’s master cylinders. As the hydraulic pressure reaches the brake it forces the pistons
outward against the pressure plate assembly (with wear pads) which compresses the brake
stack (the rotating discs and center stator) against the back plate assembly (with wear pads).
This generated frictional force is transferred to the wheel/tire through the rotating discs; which
have drive tangs to engage the main wheel, and thus slows the aircraft.

3. Main Brake Handling Procedures

Strictly observe the torque and lubtork values specified in this manual. Do not overtighten any
bolt, nut, or fitting. Handle and maintain the brake cylinder properly to protect the paint and
surface finishes.

TESTING

(2) Examine plug fitting (110) for deformation, pitting, damage to threads or scoring that
would affect sealing.
(3) Examine brake assembly for signs of leakage from piston seals (100), inlet fitting, plug
fitting (110), and bleeder fittings (120, 125). Measurable leakage is defined as more
than one drop.

D. Brake Wear Check. See Figure 1001

Refer to IPL, Figure 1 for identification of components. With the aircraft on a flat surface,
depress the brakes and set the parking brake. While the pressure plate, discs, center stator,
and back plate are compressed against one another, check lining indicator for position of the
indicator pin (IPL, 1-60). The position of the indicator pin may be seen from either the front
or aft of the aircraft. This dimension denotes a standard whereas if the indicator pin cannot
be seen, check the brake for wear, measure the distance between the pressure plate
assembly and the cylinder housing with a set of long nose Vernier calipers. If this distance
exceeds .265 inches, the brake should be fully disassembled and further inspection of the
individual wear components should be performed as specified herein.

 CM40-203 COMPONENT MAINTENANCE MANUAL WITH IPL
FOR MAIN WHEEL ASSEMBLY PART NO. 40-203

DESCRIPTION AND OPERATION

1. Main Wheel Description

The main wheel assembly is a 6.50-10, Type III wheel designed for use with a 22 x 6.75-10, 8
PR tubeless tire and a 6.50-10, 6 PR tube-type tire. The divided type main wheel facilitates tire
installation and removal. The two wheel halves are fastened together with high strength bolts,
single countersunk washers (under bolt head) and flat washers under self-locking nuts. The
wheel halves are machined from forged aluminum alloy.

An O-ring is installed on the inner wheel half to provide an air seal at the juncture of the wheel
halves. An inflation valve assembly is installed in the outer wheel half to inflate and deflate a
tubeless tire.

The wheel assembly rotates on two tapered roller bearings. The bearing cups are shrink-fit into
the hubs of each wheel half. Rubber molded type lip seals provide protection and lubricant
retention for the bearing.

The flange of the inner wheel half has nine slots that engage the drive tangs of the rotating
brake discs. The inner wheel half flange slots are lined with steel key liners (which are held in
place by a single screw and lockwire) to provide a hard wearing surface for the disc tangs and
to prevent damage to the softer metal of the wheel.

DESCRIPTION AND OPERATION

2. Main Wheel Operation

The main wheel assembly provides partial support of the weight of the aircraft and a means of
steering control. When mated with the brake assembly, the wheel assembly provides the
braking operation by driving the rotating disc members of the brake assembly.

3. Main Wheel Handling Procedures

Strictly observe the deflation and inflation procedures, and the torque and lubtork values
specified in this manual. Do not overtighten any bolt, nut, or fitting. Handle the wheel bearing
cones with extreme care. Many bearing failures can be traced to dropping or mishandling the
bearings during maintenance. Handle and maintain the wheel halves properly to protect the
paint and surface finishes.

INSPECTION / CHECK

(3) Inspect wheel halves for cracks, or structural damage. Take particular note of bead
seat and valve areas. The tire bead seat area of a wheel (see Figure 5002) is typically
an area of stress concentration and possibly subjected to trauma from tire beads and
tools used to remove tires. This area should receive special attention when inspecting
for defects at a tire change to determine airworthiness. Note that these cracks May not
be visible without the aid of penetrant inspection. Any cracks are cause for
replacement.

A. Wheels Stored With Tires Installed

(1) The length of time that a wheel assembly can be stored is governed by the storage life
of its rubber components. The usable life may be shortened by exposure to sunlight,
extrememe temperatures, and low humidity; contamination by fluids; severe operating
conditions, etc.

(2) The wheel assembly should be stored in a clean, dry storeroom. The desirable
storeroom temperature range is from 50° to 77°F (10° to 25°C). If this temperature
range cannot be maintained, temperatures as high as 125°F (51.7°C) and as low as -
20°F (-28.9°C) can be tolerated for shorter periods. Total time above 100°F (37.8°C)
shall not exceed three months. The recommended storage pressure for tires is 10 psig
(68.9 kPa).

B. Wheels Stored Without Tires Installed

(1) Short-term storage of tubeless wheel assemblies may be stored with the wheel O-ring
packing installed between the two halves.

(2) Storage of components containing rubber for longer than two years should be
assembled without the rubber based components. Those rubber based components,
e.g., O-ring packings, molded rubber grease seals, etc., are to be placed in an
ultraviolet protective package.

(3) Wheels stored without rubber components installed have an indefinite storage life.
