Cleveland Wheels & Brakes Guide AWBTSG0001-11/USA ii Reference USAGE The procedures in this technician’s guide are applicable to external design wheels and brakes and auxilliary wheels only. Many wheel and brake assemblies have a manual expressly written for their overhaul and maintenance type activities. Before using this guide, consult the Cleveland Wheels & Brakes Technical Support Team for availability of those manuals. This guide is intended as a condensed version of specific data found in AWBCMM0001, the generic Component Maintenance Manual (external design wheels & brakes). AWBCMM0001 contains detailed maintenance/overhaul procedures for external design wheels & brakes that do not have a manual. In addition to this guide and AWBCMM0001, refer to AWBPC0001, Product Catalog for illustrated parts breakdown. These documents are intended to supplement, not replace, the airframe manufacturer’s instructions when Cleveland products are used. Consult the Aircraft Maintenance Manual and Airframe Log Books (for optional installations) to confirm the approved part numbers for the particular aircraft application. If any inconsistencies are observed in this data, please notify Cleveland Wheels & Brakes Customer Support. UPDATES The technician’s guide publication number will reflect the latest issue in effect with a suffix “-X” (X being the latest issue), e.g. AWBTSG0001-6. The publication number will advance numerically with each update issued. Each page will reflect the latest issue in effect. Refer to the Revisions Highlights Page in this publication for details of each update. Consult the Parker Hannifin website, www.parker.com, for current service publications. For additional information regarding publications on CD-Rom, please contact the Cleveland Wheels & Brakes Technical Support Team.

Conditioning Procedures When new linings have been installed, it is important to condition them properly to obtain the service life designed into them. The metallic and organic linings have different operating characteristics. Separate conditioning procedures are given for metallic and organic linings. ORGANIC LININGS METALLIC LININGS 1. Taxi aircraft for 1500 feet with engine at 1700 rpm applying brake pedal force as needed to develop a 5-10 mph taxi speed. 1. Perform two (2) consecutive full stop braking applications from 30 to 35 knots. Do not allow the brake discs to cool substantially between the stops. 2. Allow the brakes to cool for 10 to 15 minutes. 2. Allow the brakes to cool for 10 to 15 minutes. 3. Apply brakes and check for restraint at high static throttle. If brakes hold, conditioning is complete. 3. Apply brakes and check for restraint at high static throttle. If brakes hold, conditioning is complete. 4. If brakes cannot hold aircraft during static run-up, allow brakes to completely cool and repeat steps 1 through 3. 4. If brakes cannot hold aircraft during static run-up, allow brakes to cool completely and repeat steps 1 through 3. These conditioning procedures will wear off high spots and generate sufficient heat to create a thin layer of glazed material at the lining friction surface. Normal brake usage should generate enough heat to maintain the glaze throughout the life of the lining. Properly conditioned linings will provide many hours of maintenance free service. A visual inspection of the brake disc will indicate the lining condition. A smooth surface, one without grooves, indicates the linings are properly glazed. If the disc is rough (grooved), the linings must be reglazed. The conditioning procedure should be performed whenever the rough disc condition is observed. Light use, such as in taxiing, will cause the glaze to be worn rapidly and reduce the designed service life of the linings and discs. CAUTION: DUE TO THE EFFICIENCY OF THESE BRAKES, EXTREMELY HARD BRAKING ON AIRCRAFT WITH TAIL WHEELS COULD RESULT IN LIFTING THE TAIL FROM THE GROUND. Cleveland Wheels & Brakes Guide AWBTSG0001-11/USA 3 B. Brake Lining Wear Limits For equipment used on Piper Aztec (using either 164-00206 or 164-03206 disc), see PRM19 or follow the procedure below: • First, measure linings as shown in Figure A1. Linings worn below .100 inch are cause for replacement. • If linings are still usable or are replaced, measure the cumulative thickness of two linings, disc and pressure plate as shown in Figure A1-1. If the stack measures less than 1.00 (1 inch) with good linings (linings above .100 inch) the brake disc is considered below minimum wear thickness and should be replaced. NOTE: On some designs the metallic lining is bonded directly to the pressure plate and back plate. In these cases, the part should be replaced when the lining material is worn to 0.030 inch (0.76 mm) thick. The minimum replacement thickness on metallic and organic linings is 0.100 inch (2.54 mm) except as noted below. Refer to Figure A1. Cleveland Wheels & Brakes Guide AWBTSG0001-11/USA 4 C. Brake Disc Minimum Thickness Figure A2 – Disc Thickness Measurement Under average field conditions, a brake disc should give years of trouble free service. However, unimproved fields, standing water, heavy industrial pollution or infrequent use of the aircraft may necessitate more frequent inspection of discs to prolong the life of the brake lining. Generally, the disc faces should be checked for wear (Figure A2 Dim. “A”), grooves, deep scratches, excessive general pitting or coning of the brake disc. Coning beyond 0.015 inch (0.381 mm) in either direction would be cause for replacement. Single or isolated grooves up to 0.030 inch (0.76 mm) deep should not be cause for replacement, although general grooving of the disc faces will reduce lining life. Discs are plated for special applications only; therefore, rust in varying degrees can occur. If a powder rust appears, one or two braking applications during taxi should wipe the disc clear. Rust allowed to progress beyond this point may require removal of the disc from wheel assembly to properly clean both faces. Wire brushing followed by sanding with 220 grit sandpaper can restore the braking surface for continued use. Note: 164-1XXXX part numbers designate chrome plated discs. 464-XXXXX part numbers designate performace gold discs which are no longer manufactured.
