just got oneway bleeder scews to put on all 3 calipers. can i just bleed them normally? i found more bleeder screws halfway up. do they only apply to ABS- i hope. 25 years of wrenching on my shovelhead have not prepared for what i thought would be a snap namely to put in new brakefluid in my gs after 30k miles. any words of wisdom from you erudite gentlemen?
