A rather big thing got delivered today (the box, no the bike).


Nice Schwinn.

Oh...the tool box. Yeah, nice.


That's my Ritchey Break-away. It has a cross geometry frame that separates into two sections, and then everything fits into a barely-legal airline size case. When I had my corporate job, and often spent weeks traveling, I took the bike with me. Now it is my go-to bike, for commuting to the nearby college campus and for fun exercise rides.

Thanks. But by the time I get done, I will not be minty.

Brake check! The pressure held overnight, a good sign.

Even better, no leaks, even at the troublesome right rear caliper.

Master cylinder fittings also dry. Yeah!!! (IMG:style_emoticons/default/cheer.gif)

I feel like I have been high-centered trying to get the brake system sealed up.

So feeling confident, I re-attached the parking brake cables and tightened the rear caliper mounting bolts.

Then I finally got back to starting to bleed the system. I used the pressure bottle to bleed all four corners twice, with lots of tapping of components and a few pumps of the brake pedal. I could hear some action in rear.

After this first effort, the initial pedal is still low (but not "zero").

And the pedal pumps up to normal with about 3 or 4 strokes. I think this is a good start.

The postman (person?) delivered 2 more bottles of Iron-X.

I went back to the wheel that I started with the bit of Iron-X I had on my shelf. Lots of purple means lots of iron crud getting dissolved.

Halfway there. This new batch is still smelly, and works perhaps a bit better.

After about an hour of treating, soaking, scrubbing, and rinsing--done! Just one more wheel to go.

I did another round of brake system bleeding, and have a firmer pedal. I also adjusted the rear caliper pad clearance.

First, I removed the pad spreader spring.

For the outer adjuster, I have the perfect wrench: a Facom socket wrench. This has an open end to allow the Allen wrench through.

Clearance set. I used .008" for the initial running. Once everything is settled, I will try for .004"

On the inside, I unscrewed the new PMB caps (with 5 mm hex indents).

The adjuster on the inside takes a 4 mm Allen wrench.

I put a dab of anti-seize on the cap before installing.
