Brakes 1994 disc brake questions.

Lucked out recently and got a pair of 1994 Mustang spindles with complete disc brake assemblies. Going to have to store them for maybe a year or two before I get my next Mustang. The pads and rotors appear to be in good condition.

I’d like to store them so that they are ready to install.

Do I apply anti-squeal compound to the backing plate?

Do I apply high temp brake grease to the the caliper piston?

Do I apply high temp brake grease to the backing plate where it contacts the caliper piston?

Do I apply high temp brake grease to the edge of the backing plate where it contacts the caliper?

Thanks in advance.

Thanks for the reply.
Do you apply any anti-squeal compound?

Thanks Mustang5L5.
