My Brembo blanks just came in and I was looking through the instructions and I was wondering what is this "piston caliper tool" its suppose to compress the caliper piston but i dont understand how to do it? Also, on the blank rotors does it matter which one goes on the right or left because none of them are labeled?

 

It makes no difference what side they go on.

As for the piston caliper tool, all you have to do it push the piston back in the caliper by hand or with a c-clamp so that the caliper will slide over the new rotor.

This page maybe helpful, it's for a mustang, but it will give you a general idea.

BTW, how do they look? I'm expecting mine this week as well.

 

They are nice and shiny but I didnt expect it to be soo heavy..thought it might be like 5 pounds or something.
Also, do I have to put new brake fluid in?

 

You shouldn't have to put fluid in unless you open the bleeder plug. If you do that, then you have to bleed your brake system. Not a bad idea anyway if the fluid's been in there for longer than 2-3 years. Be sure to watch the reservoir in the engine bay so it doesn't over flow, try to catch all of the overflow if it does, or suck out some excess with an old turkey baster. Just try not to get the fluid on the paint. If you do lose some from the reservoir, you will need to add it also.
