The wiring sketch looks like a standard 6 volt 8N system to me. Hitting the zerks with some grease might "fix" the lazy brake pedal. Check the linkage for the clutch pedal under the left footboard. If it broke, that may have been cobbled together any number of ways that might increase pedal effort.
