[Healeys] Ford versus Ferrari

[jim]

 yeah, but....
You still need to compress caliper piston, thus displacing the fluid in the caliper back toward the master cylinder and reservoir ...also too ,,on combination disk/drum systems, there is a "proportioning valve" ...to avoid back pressuring/overfilling reservoir/mucking up the proportioning valve, I bleed excess fluid at caliper ..
Maybe overkill but ..YMMV

 as long as you are removing the brake pads and not the calipers, no need bleed anything.  Honestly with some practice on the BJ8, with a full pit crew, you could probably remove and replace the rotors and pads in 5 min or less if assemblies were ready.

 Changing "rotors" ..Changing "pads" ...Changing "calipers" ...Not equivalent 

 the ONLY time I need to open the fluid lines is when I have to change "calipers"
All the caliper change directions I have seen advise to prefill/pre bleed caliper before fitting

Heat? ...Use a CO2 extinguisher (you do have a current certified one in your shop) ...I do
change pads .. c clamp to press piston back into caliper (use a large screwdriver/pry bar if you are changing pads/rotors)fluid will flow back into reservoir ...If you don't want the crud from the caliper back into the system, crack the bleeder valve..ditto for changing rotors 

Remove 2 pins to change pads//remove 2 bolts to change rotors/pads
suspend "caliper" from ? to avoid kinking/twisting flex line
remove/replace rotors ..
remove/replace pads ..

Piece o' cake (go to Les Schwab and watch how they do it)

   I wondered that myself.   Maybe some sort of check valve on the brake lines and pre-filled calipers, allowing bleeding with just a couple quick pumps on the brake pedal?
 
 Of course, it was a movie, so maybe it was the figment of some screenpaly writer's imagination?

 For those who saw the movie "Ford versus Ferrari." On the Phil Remington quick change rotor/caliper assembly, how do they avoid having to bleed the brakes?
 Just curious.
