Ebrake “pin” replacement?

How do I get the brake light to turn off?

 

Have you checked the brake fluid level?

 

Check your brake fluid level first, when brake pads wear down they take up less room in the caliper causing the brake fluid to go down in the reservoir which can trigger a light

 

Hopefully, your truck is an OBD-II compliant truck. OBD-II means "on board diagnostics, generation 2" which was instituted across the automotive industry in 1996.

If so, you will have a 16 pin receptacle diagnostic port underneath your steering wheel. And if so, I highly recommend you proceed to your nearest brick-n-mortar auto parts store and ask them to scan your OBD-II diagnostic trouble codes related to your brakes that are now stored in the engine computer. They will plug in a hand held device and read the info from your engine computer. And that will help understanding what is causing your brake light to be illuminated on your dash.

OBD-II systems were very simple in the 1990s and you shouldn't have more than 1 or 2 codes that should be fairly easily researched and resolved by surfing online.

Write down your trouble code(s) from the store and post them up here if you still need help.

 

3 things that will turn the brake warning light on

- low brake fluid level in the reservoir
Check fluid level, look for thin pads or a brake fluid leak

- parking brake switch
Make sure the switch is getting pushed when the parking brake is fully released

- pressure differential switch
This switch is where the two halves of the brake hydraulic system meet. The switch is set to move left or right if any substantial difference in pressure is detected in the brake lines.
The switch moving would usually accompanied by a large brake fluid leak or hydraulic failure. The pedal would feel weird or soft if this was the case. The differential switches rarely fail

 

On that era vehicle that warning light is entirely separate from the obd system

 

Oh, wow, thanks for the clarification. My honest mistake.

Is there a way to retrieve the info from the dash?

 

The brake light system is pretty analog. No central "brain" to hold and store codes. It's just the 3 components i mentioned above

 

Simplest thing would be check the switch on the parking lever rod....

its kinda wonky......if you twist the rod a little too much when releasing ebrake it will miss the switch

every time someone services my truck they fail to hit that switch right
and tell me the light wont go off....

I guess that track it rides in widens over time.....you can see in that 2nd pic they've bent/pinched that gap back right at the bottom of its travel.


if thats not it....its mostly a bad level sensor on the brake fluid reservoir
assuming its already full...
