BOTH front calipers stuck ? - follow up

[John Lagnese]

If you get a section of clear hose it is a self bleeder. Keep it straight,
or with a bend. There will be a column of brake fluid in it. This will keep
air from getting into the system.

Thank you to all those who have responded - the posts were all very helpful.

I am leaning towards the MC, even though I have not done a lot of diagnosis.
But this is what I have done:

1. When everything is cold, the brake calipers release just fine - I can
press and release the brake pedal, and the front wheels will spin
3. I made it home yesterday with no problem - or at least no smoke
4. This morning, the calipers started to stick just before I arrived at work
(25 minutes), based on my finely calibrated  "how well does the car coast"
gauge.

I need to crack the bleed screw at a caliper when they stick, but its yucky
on the ground now, and its dark when I get home. Is the bleed screw at the
MC the same pressure as the calipers - that would be easy to check ;-)?

Thank you all again!

Dave
