Brake Lights Remain On?

[SirBaz]

The rear lights and brake lights on my 55 Buick remain on and will not shut off......wot is the problem.....I have just had all the Brake shoes, cylinders, pipes and cables replaced and the brakes work great...but the lights stay on???

any suggestions?

Look under the dash at the brake pedal and you should see a switch on a bracket that touches against the pedal arm. Adjust in/out to open/close brake light contacts.

55 Buicks have a pressure switch mounted on the master cylinder. Replace that.

I replaced my power brake booster because of a bad diaphram. It wouldn't let the brake pedal come all the way back up. I'm not sure if this applies to the 55's but I thought I would throw it out there.

Is there any way I can fix it in the short term....might it only need adjusted?
I have my MOT this week and won't have time to send for another one at the moment.

I humbly bow to superior knowledge, I let my 55-57 Chevy history get in the way of helping a fellow Buick nut. :Dou:

They sell them at all the big parts stores. Just unplug & unscrew....screw the new one in, and reattach the wires. It's easy...but kindof a pain to get to...

I have kinda the opposite problem. My 1950 Roadmaster's brake lights only come on when I put a lot of pressure on the brake pedal. I mean I have to almost stand on the pedal for the lights to come on. Anyone know if there is an adjustment I can make to rectify this problem? All suggestions appreciated. Maybe I should start a new thread, but I was hoping someone may have some helpful info on this one. :confused:

Same story - the easiest and cheapest way to fix brake light problems on the early Buicks is to replace the switch. 90% of the time, that is the issue.
