Aren't those Porterfields a lot more expensive than comparable pads? (Carbotech)

 

Yes.
They also come with integral shims embedded in to the backing plates.

I chose the R4S as a solution for both track and street duty, keeping swaps to a minimum. Its advertised heat range is 900 degrees (while the HP Plus is 800 degrees).
Carbotech's comparable is the former Panther Plus, now known as the AX6.

 

What did a front axle set run you? (if you don't mind me asking)

 

Hey guys,

I did a customers brakes the other day and ran into the same problem.

Frikin turning the thing for like 15mins per side. Anways I wan't getting any results but did this and it ended up working.

#1: Open the sealed system by removing the cap on the Brake Fluid Reservoir.

#2: Using a 3/4" Open Ended Wrench you can use this to turn the piston from the side, not poking into it, but just like you would turn a bolt/nut.

#3: If piston appears to stop depressing then I ended up pulling on the ebrake just to get some movement out of them. They then fully expanded, sucked of course, but afterwards they started to depress without problems. just took forever, be patient and keep turning.

My shoulders were yoked after that job. honestly a 1 hr job turned into twice the time because of the frikin rear caliper pistons, arghhhhh

Glad you got it worked out, thought i would chime this in and say what worked for me.

I know what you mean. I simply don't see this kind of effort as being the norm. I'm a relatively strong guy and anyone with less strength than I wouldn't be able to get that piston back in. Rule of thumb is that if it doesn't feel natural, something is wrong.
I had the m/c cap off, ebrake disengaged, and I even took out the bleeder screw on the caliper and let the fluid run out when nothing else was working (bled/topped off fluid when I was done).

I would like to add I just did this and while the driver's side went in easy, the passenger side was absolute hell. However came up with this idea needs to get shot!

 

Well,I believe that all cars with emergency brakes will have a screw in piston on the back.

 

Yeah I know, but it still pisses me off...
