Wedge air brakes
 

Recently purchased a '75 Dodge D700 with Bendix air brakes. It's been sitting for a couple decades. Got the 361 gas motor started and it runs quite well. Because it runs I'd like to address the air brakes. I have learned that the air brakes are "wedge" style. Any older heavy truck mechanics that can suggest a good resource for parts/info/service manual on these type of brakes ?

For wedge air brakes on your 1975 Dodge D700, it’s important to find parts and manuals that fit the system. You can try these steps:

Search online: Look for forums or websites that specialize in vintage trucks or air brake systems.
