searching the parking brake switch

[Oliver]

Hi all,
apologise ... i am new here, and here in Europe .. there is few ram gen 2 specialist(s)
i got a 2*4 gen 2 from 96 ... and i just bought a second one .. a gen 2 4*4 V8 from 1998! a black one
i alraedy love it ;-) i am replacing all hydraulic brake lines right now !
i search now where the parking brake switch is physicali situated ! it seems to be locked ... the pking brake light remain ON all the time ! could someone tell me or show with picture where it is situated or how to fix it ? please ? ofc .. i release and push it all way .. no result ... normaly .. there is no relation beween the hydraulic system and the parking brake line (?)

Nevermind, I misread your post, thought you were wanting the brake light switch, not the parking brake switch.

The parking brake switch is located right behind the brake pedal, it is not connected in any way to the hydraulic system. If the brake lights are on constantly it may be related to the brake light switch.

We've had a problem before with the Wiring diagrams not matching what actually happens.

If this wiring diagram is accurate pins 6 and 5 should be disconnected when the brake pedal is in the resting position. Otherwise in the resting position pins 1,2 and 5,6 should be open, then 3,4 should be closed. If its not, just make sure they switch states when you hit the pedal.

hmmm okay thanks,
it looks like this switch don't look like a switch i will look closer, thank you.
Happy to read then you agree with the fact then there's no relation between hydraulic system and this (fu..)light
i fix this ... then i go look for the switch (i don't find an accurate translation for this ...)

That is a round bleeder screw on a caliper. You're gonna want to order a new caliper if you cant get that bleeder out with a pair of vise grips, though it looks like you have tried that approach already.

so ! NOW
the thread ... is .. metric ... M10 by 1.5 ... it has finaly been removed after heating it roughly ! BUT I GOT IT ! COOL !
rebuilt all ! no oïl leak !
after removing "the air " from the system, the parking brake light turned OFF ! it means .. there is a relation between hydraulic system and this light ! BTW .. all fixed and i am happy ;-)
NEXXXXXT .. removing exhaust sensor to replace it !
i already love my badass ;-) ! GEN 2 power

Ohh, I must've had a temporary drop of brain cells, I though your brake lights weren't working, not the brake warning light. My bad.

Yeah, there is a pressure differential switch in the master cylinder that looks for a difference in pressure between the front and rear brakes, having air in the lines will certainly cause that light to come on.

Glad you got it fixed. But it makes me wonder how little power trucks over there have? These are great trucks, but the v8's were never big power houses, at least compared to other American V-8s they were pretty standard.

if you came .. taking a look in Europe ... probably ... you will discover how crap it is
when i see th gas's price ... ... the "safety rules" .. it suks here bro ;-)
