Attn: Technical Services/Hotline Phone: 1-800-272-5464 Fax: (440) 937-5409 IM199-125 INSTALLATION MANUAL WITH IPL FOR CONVERSION KIT PART NO. 199-125 Page 3 Oct 15/00 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.

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. IM199-125 INSTALLATION MANUAL WITH IPL FOR CONVERSION KIT PART NO. 199-125 Page 5 Oct 15/00 e. Draw the two brakes together using two brake tie bolts, Item 4, two nuts, Item 6, and four 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.

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. Main Brake Assembly Figure 1 Released: 2/10/2021 Delivered from Parker Vault - VERIFY REVISION BEFORE USE CM30-162 COMPONENT MAINTENANCE MANUAL WITH IPL FOR MAIN BRAKE ASSEMBLY PART NO. 30-162 Page 2 July 31, 2017 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.

Pretest Check (Refer to IPL, Figure 1) Perform the following inspections and checks to qualify the brake assembly for testing. Do not perform testing on any brake assembly that exhibits visible signs of damage. (1) Examine exposed cylinder (30) surfaces for breaks, cracks, or other visible damage. Released: 2/10/2021 Delivered from Parker Vault - VERIFY REVISION BEFORE USE CM30-162 COMPONENT MAINTENANCE MANUAL WITH IPL FOR MAIN BRAKE ASSEMBLY PART NO. 30-162 Page 1002 July 31, 2017 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.
