AERM 1350 Name ________________________ Landing Gear Systems Laboratory/Learning Outcomes AERM 1350 Lab Project 5 Student will demonstrate the ability to use aircraft maintenance manual instructions to service caliper and replace brake linings. Procedure The student will repair a brake system: 1. Perform following tasks and record brake component dimensions: a. Remove brake assembly from axle/axle flange b. Remove lining. c. Remove piston/cylinder. d. Replace piston/cylinder. e. Replace lining f. Replace brake assembly on axle/axle flange. g. Service and bleed system h. Check operation a brake system. Required: Record Applicable Information or enter N/A (not applicable) 2. Identify applicable risks and mitigations: Answer: have eye protection and gloves for in case of 5606 mess. 3. Assigned aircraft or training aid: Answer: Piper Aircraft 28-140 4. Aircraft or component Manufacturer’s Service Information: Airplane Parts Catalog - PA-28-140, PA-28-150, PA-28-160, PA-28-180, PA-28-235, PA- 28R-180, PA-28R-200 Cherokee. 5. Record Part/Type/Model Numbers (as applicable): a. Brake MFR: Answer: Cleaveland b. Pad/Lining P/N: 2.8.6 Lab Project 5: AERM 1350 Page 1 of 3
AERM 1350 Name ________________________ Landing Gear Systems Answer: 066-10500 c. Rivet P/Ns (or description): Answer: 105-00200 d. Brake Fluid Type: Answer: MIL-5606 6. Make maintenance record entry: Answer: Went and brought the aircraft into position and put chalks around the main and nose wheels. Looked up the following resources to obtain the information needed: *Airplane Parts Catalog - PA-28-140, PA-28-150, PA-28-160, PA-28-180, PA-28-235, PA- 28R-180, PA-28R-200 Cherokee. *AWBPC0001 Cleveland Parts Product Cat-2-2 pg.: 1-22 *AWBTSG0001 Cleveland Svc-2-2 pg.18 Once data was retrieved, we read and search our specific aircraft part number and read the Airplane Service Manual- PA-28-140, PA-28-150, PA-28-160, PA-28-180, PA-28- 235, PA-28R-180, PA-28R-200 Cherokee. Once ready we unscrewed the bolt nuts attached to the brake system and took out whose line once it was also unscrewed. Once we took out the brake case’s, we took out the rivets that were attached to the brake pads, we gave a closely inspection to them and found no defects to them. After closely inspection on the break pads, we inserted our new rivets into the break pads and putted them straight back to their case and put the whole break system back to the main landing gear, and we Torqued break nuts to 75-80 inch per pounds. Once that was done, we connected the whose line to the completed break system and read the instruction to bleed the breaks according to Airplane Service Manual- PA-28- 140, PA-28-150, PA-28-160, PA-28-180, PA-28-235, PA-28R-180, PA-28R-200 Cherokee. We then Bleed the brake system by both gravity and pump methods, but did not work due to a problem that occurred which was the master cylinder output hole not letting out the MIL-5606. Further Inspection is required to find and fix the Master Cylinder and we can then proceed to do the bleed brake check. 2.8.6 Lab Project 5: AERM 1350 Page 2 of 3
