Springman, Cheap, the only time I ever locked my front  wheel on the S40 was when I grabbed way too much lever banked over past my comfort zone, other than that, no lockup ever
Springman if you didn't open the hydraulic system and aren't planning to replace your brake fluid there is absolutely no reason to bleed the brake, brake systems are sealed and don't lose fluid unless something is wrong or you open the system
