Brake lever or your brake fluid may be low in the brake reservoir. With that said, if your brake fluid is low that means your brakes need to be serviced too.

The brake fluid on the first gens needs to be near the "full" line or the light will go on.

Actually a little above the full line would be best, at least on my old rig.

Check brake fluid and if that fixes it check the front pads. May be getting time for new ones but not always.

Welcome to TW, Grab yourself a hard hat in the lobby. Just some suggestions I stole from other sites. It may help and it may not.

There is a TSB on the emergency brake pedal... The bolt comes loose, and so does the arm assembly.. That may result in the button sensor showing a brake warning light on the instrument panel. When you make a turn, it moves over..

Put it in park, get out of truck with the parking brake released.. Grab the pedal arm (above pedal) and see if it will move from left to right (driver <--> passenger) direction... Should be NO side movement at all.. IF so, tighten it, or go in to get it tightened and that might be tripping your light to...



about: 2004 Toyota Tacoma
Emergency Brake
My emergency brake light comes on and stays on when its cold out, then when the truck warms up it turns off.


This is extremely common on all Toyota trucks. The easiest way to take care of this is go buy a can of PB Blaster at your local auto parts store, lay on the ground under your truck and find the parking brake pivot. If you don't know where it is (should be drivers side about where the cab and bed meet next to the frame rail) have a friend pull the level and release it while you see what's moving. Lube the crap out of the pivot arm adjuster while you or someone else pulls it and releases it. This works 95% of the time. If not, you'll probably need to adjust the shoes in the back but like I said, should be fixed with that $3 can of PB. This is a 5 minute fix at most.

One more thing....From what I've read there is a float/bobber in the Master Cylinder that detects fluid level. Even if the fluid is at the correct service level,(visual) that float could still be sticking and not reading correctly. I assume you could pull the cover and GENTLY pull that float up to see if there is any movement upwards.

If all else fails.....Emergency Brake Light won't go out?-tape.jpg

Post Getting the Brake light to go out

I flushed the brake fluid in my non ABS 2001 Tacoma, but forgot, and left ignition on to listen to the radio. Pads and shoes are fine, just old fluid.

When I drained the master cylinder, the light was triggered because the level went down too low. To turn off the light, unplug the sensor on the driver side lower part of the master with the key off.

Turn the ignition on (don't have to start it) then back off.

Next time you turn it on, the light will come on for self test, and then go out when it senses the fluid at proper level.

I love Google. First hit when I typed in "emergency brake 2004 tacoma engine oil" So my '04's E-brake light would NOT turn off. I topped off the brake resi last night and it went away, obviously came on when the E-brake was applied.
