I am changing out my Calipers and since I'm that far in, I got SS Lines as well. Was just doing some research and not finding much. The Brake Bleeding Wiki is blank. I haven't done this on a antilock or Brembo brakes before So a couple questions:

1. What brake fluid should I use. Not flushing the system just adding as needed and I assume that will be a lot!
2. Anything to specifically watch out for?
3. Should there be any anti seize, or thread sealant used?

Thanks in advance -

Prob with factory calipers? I had some left from a one litre can. Stock is DOT 3. On the bleeder screws? No, I didn't use anything. Make sure you clean it all off very well with brake cleaner though. How were you going to fill/bleed them? THE best way is a power bleeder.

Yes, I got some OEM powder coated ones from Caliper Clinic. So I need a Quart bottle (1.05 Ltr) of brake fluid, good to know.
No thread sealant on the brake line bolts either?
Yea, I intend to use a power bleeder but I read lower it to about 9 psi.

I'd put a hose on the bleeder and route the end to a can or bottle to catch the fluid when it does reach the bleeder.

I do catch, but I don't re-use it once its been through and into a contaminated bottle.

You should use the same fluid that is in the rest of the system, unless the caliper manufacturer calls for a specific type/brand of fluid to probably be compatible with the seal material. In this case instructions on the can of the specified brake fluid need to be followed. Almost certainly it will call for all of the old fluid be removed from the system. In some very special cases one might be required to use a special flushing fluid to ensure a proper hydraulic system flush of the old fluid before using the new fluid. After you will have to note that the brake fluid in the system is not the factory fluid so if you take the car in for service someone doesn't top up the special fluid with factory fluid.

With a change in calipers, the fitting of SS brake lines, and a brake fluid flush and bleed there are a number of things to watch out for.

The new SS lines must be routed correctly and secure to prevent unwanted movement.

They all want to be connected with no leaks, that's for sure.

Regarding thread sealant I'd refer you to the installation instructions of the calipers and SS lines for any info on what (if any) thread sealant to use.

Absent any info from the caliper and SS line makers then I'd refer you to what the factory service/repair manuals have to offer on what (again if any) thread sealant to use after replacing factory calipers or brake lines.

You want to be sure you follow the correct procedure to bleed the brakes to ensure completely filling the empty lines and calipers with brake fluid. Also, I would recommend you do a brake bleed in which the ABS pump can be cycled to ensure any old/stale brake fluid is flushed from it and out the system and and the old fluid replaced with fresh fluid.
