All,
I am getting ready to re-assemble my front calipers. I split the calipers, removed the pistons and rubber bits, cleaned and painted the halves with hot pink caliper paint. (Kidding... satin black.) I will reassembly with a rebuild kit, SS pistons from TRF, and the caliper seals from Moss.
During re-assembly, I understand I should lubricate the rubber piston seal. As this is a complete restoration, I am replacing all brake lines and plan to use DOT-5 brake fluid.
Can I use Permatex Caliper lube for the piston sea? Or, should i use brake fluid, or something else? (This stuff: https://www.permatex.com/products/l...kes/Permatex-ultra-disc-brake-caliper-lube-4/) There is a "Castrol Red Rubber Grease" that seems perfect, but is unavailable in the US as far as I can tell.
I lean towards using a grease over brake fluid, as I figure during normal driving, fresh brake fluid will only come into contact with the seal edge. The lube is thick, and presumably will last longer than brake fluid.
Finally, is there a preferred brand of DOT-5 brake fluid? (Not intending to start a "flame war" between everyone's favorite brands, just curious if there is a clear winner for our cars.)
Thanks, and have a wonderful weekend! (I will spend it wrenching on my daily driver instead of the TR4A; front brakes and bearings.)
