i got a 92 dx hatch that i am putting integra rear and front brakes on i have brand new calipers and hoses but i am using a used integra master and prop valve my steel lines are in great shape so i dont want to change them but the question i have is i am using synthetic fluid in my new system how do i flush all existing old fluide whith out hooking my calipers up and doing bleeds is their anything i could flush it with

 

use a vacuum bleeder and flush it with the same fluid that you will be puting into the system when you are done with the swap

 

bump i dont have a vacume pump

 

also what is a good syn brake fluid to use that has good heat resistance and could i use a silicone based fluid
