My e-brake light in the dash display is coming on sometimes when I accelerate, and pretty much anytime I accelerate hard, havent changed anything and this just started happening past couple days. Any ideas?

your brake fluid is low, check the resevoir.

Thats exactly it. The fluid for the clutch and brakes are shared, should I just top it off with the recommended fluid or is there anything special you guys would recommend putting in?

i use motul dot 5.1 but if youre just topping it off then any high quality dot 3 will do.

the synthetic castrol or i think valvoline brake fluid is pretty good and its compatable with regular brake fluids.

I run Valvoline Synpower synthetic (I believe) brake fluid. It exceeds DOT 4 ratings and from the research I did it’s the best "over the counter" brake fluid you can buy. It is also compatible with other fluids so you can just add what you need into the reservoir.

It might not be the brake fluid, the emergency brake handle can actually be coming up enough under hard acceleration to set off the light.

From Rob Robinette's:

Also, my brake light will come on when I drive hard......... Anyone know why?
This could be your brake fluid close to the low mark. When you jostle the car around, it could be tripping the fluid sensor. Also, your parking brake sensor may be loose.
There is a very cheesy switch located to the rear and below the parking brake lever. Your parking brake warning lamp is illuminating, most likely, due to one of the following reasons:
Your emergency brake handle is not fully in the down position. There might also be a foreign object preventing it from going all the way down. Even one "click" up from the down position can make the light go on and off.
Your emergency brake handle is loose, allowing it to slide slightly sideways in the down position. This will cause the parking brake switch to not engage fully.
Your parking brake switch is loose, bad or failing. The console panel pops off pretty easy, allowing access to this switch. The switch is located just below the back of the parking brake lever boot. Good luck, hopefully it will be an easy fix!

My old POS BMW beater used to do what rynberg's describing, except it would occur during extended right turns.
