Need help with brakelights--- M818

[100dollarman]

I have this semi-custom M818 being picked up by the customer on Sunday. All of the lights work except the brakelights. My guy says he cant find a brakelight switch anywhere.

Can anyone give me any tips on where the switch is, or other things I should look for to make them work?

Thank you in advance for any helpful info!!!

(didnt find any info with a quick search)

Dont know about a 5 ton but my duice was the sameway when I bought it replaced the switch on the master cylinder got it at NAPA not Gov but worked

Yes- I figure there has to be a switch on either the pedal linkage or the master cylinder. I didnt have time to look today, but my guy tells me that he couldnt find anykind of a brakelight switch anywhere.

Thanks!!!

aww,Its gotta be there most liklly on the master cylinder, military should have a water proof wire going to the frount end of the master cyl. Keep looking

Check the bulbs! Check the grounding of the lamp-units, both mounting bolts have to make good contact.

Well, I never did find a switch, but got the lights working!!!

Found that the master cyl was low on fluid. Filled it and the brake lights started working!!!

I dont know how or why... but they work now!

Thanks everyone for the suggestions!

the switch is mounted to the drivers side frame rail just behind the master cylinder and hes 2 wires with 1 air line going to it.
