I put the O ring pistons in the SS sleeved calipers on my 69. I would assume that if your caliper bores are good...not pitted or scored, that they should fit in the standard non sleeved caliper bores too. I assume you're doing this to alleviate "air pumping" back into the system, and not to stop leakage. Hope this helps. Chuck
I am doing this for the cavitation/air pumping reason but also for the reliability standpoint (leaking/longevity). I'm unsure of the condition of the bores.
I've seen an o-ring conversion kit on Ecklers site (PART# 37543) but I have not seen it in their catalog that I just got. Has anyone seen this conversion? Does it includes a SS sleeve or is there a sleeve available for this purpose?
I'm building this car as a fun driver, non racer, non show car and not an original museum piece. The brakes are for my peace of mind.
