brake switch

is there a better way of hooking up the brake switch. i just finished installing and bleeding my brakes, and the plastic part of the switch is dripping. i,m planning on installing another one,that i have. i never like the fact that it was not a double master cylinder. and i would hate to loose brakes over a faulty brake switch.

I'm assuming you're using the pressure style brake light switch. They are a prone point of failure. I've heard many guys say they like to use a Harley-Davidson switch as it's a higher quality part and has a lower pressure setting for closing the circuit and having the brake lights come on faster. It might be worth looking in to.

John, when I was putting my truck together, i had entertained a setup like that for the clutch safety switch. I never did get around to putting it in. And, i guess in the future when my break switch leaks, I will do something similar. I remember going thru 2 of them while assembling.

I used a mechanical switch on my 49 much like this one. Fabricated a bracket under the brake pedal. Worked great.

The girlfriend (years ago...many years ago) had a Rambler that had a brake light problem. The brake light switch was a pressure type but it screwed in to the underside of the master cylinder where every bit of crud in the brake fluid system collected. No wonder that motor car company is no longer with us...

opened it up , looks like the rubber was turned in a melling . i suspect thats why it leaked,the surface of the rubber was to rough. didn,t get to try it yet , i,m afraid my new copper washers are not sealing good. i had to file one to the right diameter , and the material looks cheap. looks like it weeps by the washers !

The OEM units were pretty good, used what I think was an original, up until a year or two ago. Had completely replaced the brake system except for the switch. A full bore panic stop, locked the tires up and everything, and after that it no longer would illuminate brake lights without serious braking pressure. It got "lazy". Still worked though, and didn't leak.

C1AZ-13480-A (replaced 0A-13480) .. Stop Lamp Switch (Motorcraft SW-24) / Available from Ford and auto parts stores.

1940/66 myriad FoMoCo vehicles. This pressure activated switch is notorious for getting gummed up with dirty brake fluid. It was also used by Studebaker, Nash, Packard and probably others as well.

Rambler was founded in 1902 by the Thomas B. Jeffrey Co. of Kenosha WI. In 1916, after Charlie Nash resigned as GM's president, he purchased the Jeffrey Co., renaming it Nash Motors.

In 1950 Nash reintroduced the Rambler as America's first compact car. In 1954, Nash merged with Hudson, forming American Motors (AMC).

In 1979, after suffering huge financial losses in the volatile car biz, Renault acquired a major interest in AMC, then proceeded to run it into the ground.

What remained of AMC was purchased by Chrysler in 1987.
