Front Wheel Cylinder Repair Kit

1" bore

Complete repair kit for overhauling front wheel cylinders with 1" (25.4 mm) bore. Contains all necessary wear parts to professionally restore worn or leaking front wheel cylinders without replacing the entire cylinder.

Bore

1" (25.4 mm)

Application

Front wheel cylinders

Origin

USA

Kit contents

2 cups, 2 pistons, 1 spring

Features

  • Complete with rubber cups and pistons
  • Spring included for correct return
  • Suitable for front wheels with 9" drum brakes
  • Direct replacement for worn original parts
  • For cylinders with 1" bore

★ High-quality reproduction to original specifications. Essential component for hydraulic brake system restoration.

Application

Fits front wheel cylinders with 1" bore for various post-war jeep models with 9" drum brakes. Note: rear wheels typically use cylinders with 3/4" bore — this is a front wheel kit.

Installation notes

Before installation, check that the cylinder bore is smooth and undamaged — if pitting or scoring is present, the complete cylinder must be replaced. Clean all components thoroughly with brake cleaner. Lightly lubricate the new cups and pistons with fresh brake fluid (SAE 70-R3 / DOT 3) before assembly. Bleed the brake system completely after installation.

Compatibility

Exclusively for front wheel cylinders with 1" bore. Rear wheels use smaller cylinders (3/4"). Not interchangeable. Check your cylinder bore before ordering — use callipers or compare with the original piston.

Historical context

The hydraulic brake system of post-war Willys jeeps used larger cylinders at the front (1") than at the rear (3/4") for balanced brake force distribution. This configuration was standard on military and civilian models with 9" drum brakes.
