I have 2002 tacoma V6 dbl cab. Recently, the brake light in th edash comes
on when I brake hard or more so when I'm on an incline. I've checked the
brake fluid level and it seems fine. Braking seems to work fine. Anyideas
on why this is happening? thanks all

I know that the brake fluid res. looks full , but just add little bit of
fluid . the switch in the res . is very sensitive. I bet the light goes
out.

Or replace the worn pads, which is the real problem.

The fluid level is slightly low.
If you don't do anything, the next step will be for the light to come
on during cold mornings.

Now is the time to inspect and possibly replace the pads. As the pads
wear, the fluid level in the res drops.
DON'T simply add more fluid... it will overflow when you replace the
pads unless it is actually leaking (which is unlikely).

You're slightly confused there - the first step is to look at the
pad condition before you add fluid, and see if there's at least 1/16
of wear left in the pads - if there's some wear left in them, add
fluid to make up for the volume loss. (Or have a mechanic check the
pad condition - and show you where to look to check them for yourself
next time, it's not a difficult job on most cars.)

It won't hurt to add brake fluid even if you will need new front
pads very soon - when they go to change the brakes, they should also
bleed the brake system, and that will drain off the excess fluid you
added. If they do it properly they'll use a liter or two of fresh
brake fluid to flush all the old brake fluid out of the system.
