The following article was released by GM on May 15, 1948. It was sent to all Chevrolet and GMC dealers and was to correct a problem with the location of the 1948 Brake release handle.
Brake Release Handle – Change of Location – 1/2 and 3/4 Ton Models
Some requests have been received for a method of changing the position of the brake release handle on the above models to prevent some operators striking their knees when entering the vehicle. The present location of the release handle is shown in Fig. 75.
In cases where it may become necessary to change the location of the handle, the position shown in Fig. 76 is recommended.
To re-operate proceed as follows
1. Remove the brake release handle, the release rod and the bracket at the instrument panel.
2. Drill two holes in the instrument panel for the new position of the bracket, 1- 1/2″ to the right of the original bolt holes.
3. Turn the bracket around so that the offset is towards the front and assemble to the new holes in the instrument panel, as shown in Fig. 76.
