Hey Phil:

Sounds like something is sticking.

First divide the system by disconnecting the front brake cables at the clevis pins. If the problem persists look for binding pivots and cables sticking where they pass through the chassis behind the front wheels. Remove the cover plates and check for hardened grease at that point.

If the problem is not present with the cables disconnected check for binding equalizer bars.

The wheels should spin free with no brake drag. If there is drag it should be eliminated.

The chassis lubricator should be working and the front brake actuators should be getting oil. If not, the sticking problem may be due to lack of oil. If fixing the lubricator is beyond your interests an oil can may help.

The actuator pivots on the frame are sometimes put together wrong and the binding will cause problems due to toe out on turns. The inner wheel turns sharper than the outside wheel and that extra motion has to go somewhere.
