I am using spindles from a 1954 3100, and the upper bolts holes where the backing plate mounts to the spindle are a different size than the 1950. The spindles from the '50 have larger upper holes on the spindle (7/16"), while the '54 spindles have (5/16" I think). Why the difference? | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 |
The 1950 brake system (Huck Brakes) is significantly different from the 1954 brake system (Bendix Brakes). The backing plates, spindles, and other and brake system parts are different.

The backing plates, spindles, and other and brake system parts are different. I found that when I went to inspect my brakes that one side had huck brakes and the other bendix, which lead to my axle rebuild. I have all the components for the bendix brakes now. Should I swap the spindles then with the ones with the correct size rather than drill the holes out to a larger dia? | | |
