theres no leaks or anything.

 

Any fluid in the master cylinder? The light comes on when the pressure goes low on one side of the combination valve. This forces the warning switch over to one side creating a contact to ground. If you're not losing fluid anywhere. check the wiring to see if it's grounded out anywhere.

 

Could be a bad sensor in the master cylinder area

 

How do i fix it and is it an easy fix? also, my brakes knock sometimes. i think its only the front right that knocks, what could that be? could it have anything to do with the light?

 

ive never heard of a brake knock before,have u ever pulled the tires off and checked the brakes/pads and such?

 

Well im not 100% sure that its the brake thats knocking. im also thinking it could be the shocks. can it be the shocks?
