[AT] OT '68 Dodge truck brake problem

[Richard Walker]

I'm posting this for a friend who has been having a heck of a 
frustrating time trying to troubleshoot a brake problem with his '68 
Dodge truck.  Any suggestions would be appreciated, thanks.  -  Richard



My problem concerns my ancient 1968 Dodge 3/4 ton Pickup. I have owned 
this truck for 30+ years and it has never given me a problem I could not 
solve, but now I'm out of ideas. Recently (and suddenly) it started 
locking up a wheel when the brakes were applied. Visual observation 
confirmed that it was the right rear wheel. When I say locks up, that's 
exactly what happens. It stops going around right NOW. And leaves a tire 
mark on the pavement where it was and there's a smell of burnt rubber in 
the air. It should be noted that if the brake pedal is feathered very 
lightly, the truck slows down, but even a little normal pedal pressure 
causes lock-up. This is such a simple brake system -- no self adjusters, 
parking brake fully relaxed. All four drums have been off; no broken 
springs or missing attachment parts; the RR wheel cylinder has been 
rebuilt (again). Any ideas ?  -  Bernie
