Poured fresh brake fluid in the cylinder and installed the new O-ring.
I like to assemble the piston with the dust shield and heat shield before installing into the caliper. Main reason is it is easier to get the piston in the correct position with the heat shield on.
Coat piston with brake fluid and install in caliper by press down with your both sets of fingers.
Once the pistons are almost down, you can press the rubber dust shield into place on the body of the caliper.
Caliper is ready to go. Install on the car and bleed the brake lines. Look for leaks. If leaking, then you’ll need to do the process over again and figure out why it leaked.
Rear calipers are basically the same process. Hope this helps somebody save a bit of money!
