John Deere Tractors:

  • 2030 After Serial Number 187301, 2440, 2630, 2640

John Deere Backhoe Loaders:

  • 300B

Common Use Case or Symptoms:

Use when a brake grabs or will not release, the pedal goes soft, or the plate is scored and heat-checked — on a 2640 a dragging brake cooks the axle oil and takes the discs with it.

Key Notes:

  • Part Numbers: T52029, R55774, 170415
  • Weight: 14.38 lbs
  • Application: Brake plate assembly, actuating plate

  • Serial Number Notes: 2030 fits After Serial Number 187301.
  • Manufacturer: A & I Products

Why Choose Broken Tractor:

  • Machined to the Original Bore: 8.663" inside and 12.111" outside — held tight because the plate has to float square or the brakes drag.
  • Supersedes R55774: The number in the older service manuals, brought forward to what A & I builds now.
  • Sealing Washers Available: R50704 and T135749 are the washers that go with it — worth adding while the axle is open.
