i personally dont like brass sleeving... think about it... now the piston metal is much harder and will wear the brass... not so much initially, but if any debris make it through the lines into the cyl, it will score easily... same with dust or sand on the outer side of the pistons... really.... at 80 a piece..its still not a lifetime cure, for 40, i'd just get the brand new one... sure its prone to rust as being cast iron, but i'm sure it'll last 40 yrs as did your old 1, thats better, at half price, life potential is only a probable 10 yrs less... by then who knows if it will even matter... if thats a concern, just spend another 10 a piece and get stainless sleeves. i'd go for the cheap way out... besides, brakes only slow you down.... bad in performance vehicles :-] jim |
