brake light keeps coming on and off

I just noticed when im driving the brake light keeps coming on and off, it goes off at lower speeeds but when u downshift and the engine revs up it comes on and when your cruising at like 65 70 it stays on and goes off when you slow down, obvioulsy i checked the brake handle hahah, it also comes on when you booost hard (pretty ironic that when you step on the gas hard it comes on hahha)

If you are low on brake fluid in the MC the light will come on.

That said check your brake pads as they wear it takes more fluid to compress the pistons hence the level in the MC goes down more triggering the light

There is no light just for the ebrake. The light is for the ebrake switch in addition to low fluid in the master cylinder.

EVO calls for DOT3 or DOT4 Fluid. For topping off any will work

Yea they can be mixed for just topping it off no worries. I use Motul or ATE Super blue in my car and totally bleed the entire system once a year or so.

If your just looking to top it off and not bleed the entire system grab some Pennzoil DOT 3/4 and top it off
