Brake fluid reservoir is ok but don't throw away the old cap with the fluid level sensor built in. I did that and now I have to buy a new cap/level sensor because the new one is wired the other way around inside. My brake light is always on now because it thinks the brake fluid is low. Now if it was really low then it would be connected in such a way that it would consider it full. Be aware, I hope it's not a problem for you
