When the pressure builds that way and then just pops loose, the interior
lining of the brake hose could be deteriorated. A loose flap from the
lining could act as an obstruction, resulting in a spongy feel with poor
braking performance. On the wheel in question, if applying the brakes
doesn't move the caliper piston and you know the piston and sliders are
free, then the hose is suspect.

Hmmmm....I think I'll have another look at this...

This is NOT good news...

Hoses are cheaper than calipers - the hose in question would be the flexible
one between the body and caliper or wheel cylinder, not the metal brake line
from the master cylinder to the flex hose. You will probably need a flare
nut wrench to break the connections free. IIRC, you will need a 10 mm
wrench on a Toyota, probably the same on a Subie.

I took a look at the setup when I did the other side this morning. Yeah,
they join at the inner fender. Doesn't look too tough. I sprayed it with
GM Heat Riser Lubricant (IMHO, much better then Blaster...) and the hose
is $22 from AZ, but I'll bet it's cheaper from a Suby dealer. Most of the
parts I've bought for this have been! (Go figure!)

You've mastered the art of asking a question without actually 'asking'
the question. Fer sure..Mom teach you that?
