It's always important to check out yer entire brake system if yer gonna do some part of it. At least clean and inspect the rears. Pull, inspect, relube/reassemble.

Suck the old stuff out of the master cylinder and put new stuff in. Stay away from the DOT 5 stuff. Bleed out everything...including the proportional valve. <img src="/forums/images/graemlins/wink.gif" alt="" />
