Title: Stainless Steel Pistons for Brakes Post by: KFH on September 25, 2010, 10:03:09 PM I had a mate of mine turn some stainless pistons up for my brakes. The cylinders have be relined with stainless also. Should I use rubber grease or just brake fluid when I reassemble them? My experience with rubber grease is that after several years it goes gooey.

Good question John ??? ??? most calipers even after market [Willwood, Outlaw ] etc use an aluminium body with stainless pistons.. OME use Aluminium or castiron bodies with stainless pistons.. Keith better do some research ....FC427....John Title: Re: Stainless Steel Pistons for Brakes Post by: Old_Mt_Isa_Boy on October 01, 2010, 09:43:00 PM Where's Ken 8) If he doesn't know where all in trouble.

You shouldn't put similar metals together. I have seen original cast iron cylinders with steel pistons and these seem to work OK. Both the aluminium and steel pistons corrode when they get dry. I think I would use aluminium pistons in stainless sleeves rather than stainless steel. I personally would use rubber grease as well since most damage is done when the piston to sleeve interface goes dry rather than a little gooey. Ken |
