How many miles on this master cylinder?

Have you noticed if yer brake fluid has been black before any recent bleeds? There is a rebuild kit from Toyota...not sure on the part number though.

With all the stuff you've been doing to yer T-100...probably wouldn't hurt to take a shot at it. Just keep in mind that if you go fer a rebuild, the bore might be hosed with corrosion. Just prepare yerself fer that possibility. <img src="/forums/images/graemlins/wink.gif" alt="" />
