[s-cars] Brakes-S6, soft and spongy.. LONG

[Postupack, Jeff]

Thanks for the reply Taka!
"I've changed my rear brakes twice and I've never had to crack a bleeder
in order to get
the pistons to retract."
I thought it was unusual to crack open the bleeder as well for piston
retraction.
Perhaps my caliper piston tool was inadequate, a scissor type device
with a ratchet to rotate the piston.
Perhaps I didn't use enough force to push the piston back inside.
 
I pressure bled this system twice. I use clear tubing at the bleeder so
I  can inspect for bubbles.
TO the best of my knowledge there is no air in that system.
 
I think it's the Bomb, after reading Fred Munro's reply.
Jeff

	Jeff-
	I've changed my rear brakes twice and I've never had to crack a
bleeder in order to get
	the pistons to retract.
	
	I would not have cracked the system to change the pads and would
have definitely started
	the car and pumped the brakes to get the rear calipers to adjust
before doing a full system bleed.
	
	Did you get clean fluid both times you bled the brakes? No
bubbles?
	
	I would keep bleeding- I've had to bleed the full system twice
to get a firm pedal- the ABS 
	pump makes things difficult.
	
	Was this a pressure bleed system or a vacuum bleed?
