Brake piston cleaning and installation

[kuoh]

I finally decided to take apart my brakes and clean and reinstall new seals but like always, half way through the job, I'm stuck with questions.

First, what can be used to clean the pistons and the bore? The manual I have says not to use any mineral based cleaner. My choices were generic brake cleaner, denatured alcohol, and some Castrol Superclean solvent. The Castrol label said it contains some sort of "sillicate" which I took to mean some sort of minerals and I don't know what denatured alcohol has in it, so I used the brake cleaner.

My second question is what the packets of red stuff that came with the seal kit is? Is it a lube to help the pistons back in the bore or some sort of glue to hold the dust seal?

Lastly, what's the best way to install the new seals? It looks like it's not going to be easy to get the seal seated on both the bore and the piston.

HELP!!
