thanks guys for the response, i would love to do this myself but dang i am just suck at with this stuff, i wonder if there is any guide that show you how to do this correctly, because i don't want to screw around and later the brake mess up even more.
thanks for the hint, i guess i just got jacked ... i've trusted this guy and bring my car there whenever i got problem, but i guess he lost a loyal customer.
maybe i should buy parts online and just bring to shop to let them do it and pay for labor.
