Brake light sensitivity 56 Packard

Morning - I have to really press down hard on the brake before the tail lights come on. Is there a way perhaps to adjust the pedal or sensitivity so that they come one as soon as I touch the pedal.

As I'm sure you all experience - people love to come right upon my bumper when I'm driving to see the car - when i touch the brake to decelerate - the lights don't engage so they don't know i'm slowing/stopping.... no bueno.

Appreciate any input.

The 55-6 hydraulic brake switches are a well known failure item and is probably the culprit. About the only solution is to change the switch which on a 55-6 is located on top of frame rail below the air vent tube and roughly under the battery.

The NOS 3 prong switches used in torsion level cars are in short supply and expensive so a conversion using a 2 terminal easily found switch and a relay is the suggested replacement. You may already have this conversion but if not, full conversion kits are available from a couple of vendors or you can make your own. You can also convert to a mechanical switch operated directly by the brake pedal arm. Kits are also available for that conversion or again, you can make your own.

Once you find out what you have or decide on what you want to do additional information on the various options can be posted.

I had the same problem with my 55 Clipper (coil and leaf spring suspension). Changing the brake light switch fixed the problem. Some switches do not play well with silicone (DOT5) fluid.
