Red light with the letter B on it

[thomas]

Hello!

This is a quick question for anyone. What does the red light indicator with the letter "B"mean on the bottom of the RPM gauge? I have a '72 3.0 cs automatic. It never came on and now it started to flicker. Is it the hand brake indicator that is sensitve? Thx
Please excuse my ignorance...German is not my language.

Low brake fluid indicator (or handbrake partially on).

The handbrake switch at the rear of the lever (under the rubber boot) is notoriously finicky. Pushing it around with your finger will usually show where it is triggered to be 'off.' It's adjustable up and down, but not left to right, and after years of abuse, the handbrake lever and its pin hinge get wobbled out of line.

Wasn't Paul Cain selling new and improved hinge pins?
