BLUF: Using any brake fluid other than MIL-PRF-46176 in the M119A3 howitzer’s brake fluid reservoir can cause brake failure and possibly a fire.
Crewmen, make sure you’re using the correct brake fluid in your M119A3 towed howitzer. Using the wrong brake fluid can cause the brakes to lock up and catch fire!
Some crew members are using petroleum base hydraulic fluid (OHT) instead of the required brake fluid.
The
only brake fluid you should put in your howitzer’s brake fluid reservoir is MIL-PRF-46176. Get a gallon with NSN 9150-01-102-9455. Check out WP 0084 and WP 0085 in TM 9-1015-260-10 (Sep 21) for more information about maintaining your howitzer’s braking system.
