Brake light could also come on if you have a lot of air in the lines.

Most brake pads, they will start to squeal when you need new ones.

How will the brake lights come on if you have air in the lines?
The brake light is triggered by a low fluid sensor.

Mine are squeeling like mad and my brake light is on. Good thing I got me some new rotors and pads in the closet. That will be this weekends little project I guess.

the metal squeel is the lil metal "nipple" thats impedded in the brake pads to let u know when its going thin.... unfortunately not all pads have this (especially the performance pads)

As your brake pads decrease in thickness, fluid sits lower in the reservoir because the pistons in your caliper sit closer to the rotor. This effectively lowers your brake fluid level by increasing the resting fluid volume in your braking system.

3. YES. If your brake light goes on in your dashboard, it means you have low fluid and thus significant pad wear.

4. Many pads incorporate sort of a last ditch safety measure for pads and will introduce something that will actually make the pads squeal to notify you that the pad is on its way out.
Exactly correct.

2 weeks ago, my brake light came on because the fluid was low. I added just a little to keep the light off but knew I was going to need pads soon. Last weekend, got a NASTY grinding noise from the right rear brake. Opps... time for pads ASAP! Did a quick visual and I have about 2mm of pad left on all the corners. I've parked the car until I can get new pads on... heck, the motorcycle is more fun anyways

I replaced my 2g GS-T pistons, and did a god awful job of bleeding the brakes. My brake fluid resevoir said I was full of brake fluid, but as soon as I drove off, did a couple hard stops, the brake light came on.

Properly bled my brakes and the light went away.

Your brake fluid sensor doesn't sense air in your brakes.
What probably happened was that you didn't bleed them properly. The air made it's way out of the system via the reservoir and thus your fluid dropped because of it.

When you bled again and re-filled your reservoir with fluid, you allowed the sensor to be covered in fluid.

Hawk street- way less dust, better braking- I am overall happy- except that the pads cost a fortune here in hawaii, and i didn't have time to order them and have them shipped.

another way to check is to physically look at the pad.. If you only see like 1-2cm of pad left ( someone double check on the thickness measurement) its time to change pads.

I wouldn't wait until your brake light comes on.. but thats me.

The light might come on when you need pads but it would only be a lucky coinicidence. The light comes on to warn you that you are low on brake fluid. That, and to warn you that the parking brake is on.

Since few people replace the pads on all four wheels at the same time; the rears usually wear out first, this "pad wear warning" would then be useless. So, I am pretty sure the Mitsu engineers never intended the light as a pad wear indicator.
