Application
This wheel cylinder fits CJ-2A (1945-1949), CJ-3A (1949-1953), CJ-3B (1953-1964) and M38 (1950-1952) with 9" rear drum brakes. All vehicles with the standard 9" x 1-3/4" rear brake configuration use this 3/4" cylinder. For comparison: front wheel cylinders have a 1" bore.
Installation notes
Always replace wheel cylinders in pairs (left and right simultaneously) for uniform braking action. Bleed the brake system thoroughly after installation. Check the brake drums for wear and out-of-round, and inspect the brake shoes before fitting new cylinders. The eccentric adjustment mechanism requires correct adjustment for optimal braking performance.
Compatibility
Please note: this 3/4" cylinder is specific to the rear axle. Front wheel cylinders have a larger bore of 1" (25.4 mm). Not compatible with later CJ models with larger brake drums or disc brakes. Always verify the brake drum diameter (9" x 1-3/4") before ordering.
Historical context
The hydraulic brake system with 9" diameter drum brakes was standard on the CJ series and M38 military jeeps from the early post-war period. This configuration built upon the proven design of the wartime MB and GPW.
