In case you need to remove rotors, or work on car, and need to remove brake parts, here is a DIY set of caliper removal tools T10439 (Porsche Number). Purchasing will cost you about $40/pair.
They will slide into the hole for caliper bolt (that affixes the caliper to the caliper carrier).
They are coated with shrink tubing that was shrunk to make the rods flat.
The shrink tubing serves as material that will compress slightly, and will prevent the caliper from slide back towards the rotor.
When removing rotors, remove one bolt, slide the rod into hole. Remove next bolt, slide next rod into that hole. Remove the brake line mount behind the steering knuckle hub, and then gently slide caliper on the rods away from the rotor, until rotor can be removed.


To make these, go to local Home Depot. Hardware section. Find aluminum rod 3/8 x 36". Cost is about $5.47. It will make you 4 rods. You need 4 only if you need to remove both front rotors. Otherwise only 2 are needed.
After you buy, cut into pieces of 8".
Use file to smooth and round off edges of each rod.
Get shrink tubing to go over the rods. I got 17mm tubing in 5cm (50mm) lengths, but if you can get one long piece, just as good.
Slide tubing over rod and use heat gun or any heat source (like your stove), to shrink the tubing around the rod.
for extra measure you can put 2 layers of shrink tubing.
When all said and done, they will look like pic below.

 

very cool nice work.

another source for the bars is onlinemetals.com, not always the cheapest but you can get custom cuts very reasonably. (12" 6061T6 .375" = $1.83 each + shipping)

 

I like your invention, engineering mind. GREAT !!! Thank you for that.

 

Fir good fit make each rod about 8 inches or so. Too long and you won th have clearance to insert them into caliper holes unless you also remove the wheel well lining.
