Have you tried Oven cleaner?
No, since oven cleaner is the amateur method for stripping anodizing. Right now I am pretty happy with the iron-removing fluid.

Unfortunately, my bottle of Iron-X was almost empty, so I only got about one-fourth the way around. More stuff ordered.
Viel besser!Slow wins the race.
One thing I found useful in cleaning the anodized Fuchs on 911's was a mixture of white vinegar and hot water.
Not sure if that would be helpful for you on the front sides?
Slow for sure, but it works. Right now I only have 1.75 wheels still to clean.
Thanks for the vinegar tip. I will see how that works.

Got some more tools (More Tools!), to help reach all the brake system fittings without pulling the engine.
bkrantz
Feb 9 2022, 08:09 PM
Good thing, since at least some of the fittings on the pressure regulator valve are still weeping.
bkrantz
Feb 9 2022, 08:12 PM
Start with the flare nut crows foot wrenches.
bkrantz
Feb 9 2022, 08:14 PM
The 11 mm on a 6 inch extension is perfect for one of the fittings on top. I was able to tighten this one quite a bit.
bkrantz
Feb 9 2022, 08:16 PM
Then I used the 11 mm ratcheting wrench, which also has a flare nut style engagement on the other side. Also quite a bit of tightening.
bkrantz
Feb 9 2022, 08:20 PM
I also got some hydraulic fitting sealant, as recommended by PMB. This is for the problematic fittings on the rear calipers.
bkrantz
Feb 9 2022, 08:22 PM
Once again I took the calipers out so I can fully access the fittings on top. I removed and cleaned the hard lines, and the seat inside the caliper body.
bkrantz
Feb 9 2022, 08:25 PM
Then a thin ring of sealant on the flare.
bkrantz
Feb 9 2022, 08:28 PM
And then I REALLY tightened the hard line fitting.
bkrantz
Feb 9 2022, 08:29 PM
One more thing delivered: some more hi-temp wrap, nominally for 2 inch ID.
bkrantz
Feb 9 2022, 08:32 PM
I used a length for the bundle of cables under the engine, including clutch cable, speedo cable, and O2 sensor cable. Mostly I am worried about the O2 cable plastic plug that sits under the right cylinders. Probably being paranoid, but at least its shiny.
bkrantz
Feb 10 2022, 09:07 PM
I connected the rear caliper lines, and then tightened all the other connections I did not get to yesterday.
bkrantz
Feb 10 2022, 09:10 PM
I then did a quick bleed, to make sure I have fluid throughout the system. No leaks yet.
bkrantz
Feb 10 2022, 09:11 PM
I then left the system pressurized to about 20 psi. It will sit overnight.
bkrantz
Feb 10 2022, 09:12 PM
A rather big thing got delivered today (the box, no the bike).
bkrantz
Feb 10 2022, 09:14 PM
I splurged on a new tool cart, from Harbor Freight. I looked at quite a few, online and in person, and this seems to be the best value.
bkrantz
Feb 10 2022, 09:17 PM
The new cart is 72" long and 22" deep. I have twice as much space as in my old cart, plus drawers that are more than long enough for big tools.

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.

Feb 11 2022, 08:33 PM
Brake check! The pressure held overnight, a good sign.
bkrantz
Feb 11 2022, 08:35 PM
Even better, no leaks, even at the troublesome right rear caliper.
bkrantz
Feb 11 2022, 08:37 PM
Master cylinder fittings also dry. Yeah!!!
I feel like I have been high-centered trying to get the brake system sealed up.
bkrantz
Feb 11 2022, 08:39 PM
So feeling confident, I re-attached the parking brake cables and tightened the rear caliper mounting bolts.
bkrantz
Feb 11 2022, 08:42 PM
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").
bkrantz
Feb 11 2022, 08:44 PM
And the pedal pumps up to normal with about 3 or 4 strokes. I think this is a good start.
bkrantz
Feb 11 2022, 08:45 PM
The postman (person?) delivered 2 more bottles of Iron-X.
bkrantz
Feb 11 2022, 08:47 PM
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.
bkrantz
Feb 11 2022, 08:49 PM
Halfway there. This new batch is still smelly, and works perhaps a bit better.
bkrantz
Feb 11 2022, 08:50 PM
After about an hour of treating, soaking, scrubbing, and rinsing--done! Just one more wheel to go.
bkrantz
Feb 12 2022, 08:50 PM
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.
bkrantz
Feb 12 2022, 08:55 PM
For the outer adjuster, I have the perfect wrench: a Facom socket wrench. This has an open end to allow the Allen wrench through.
bkrantz
Feb 12 2022, 08:57 PM
Clearance set. I used .008" for the initial running. Once everything is settled, I will try for .004"
bkrantz
Feb 12 2022, 08:59 PM
On the inside, I unscrewed the new PMB caps (with 5 mm hex indents).
bkrantz
Feb 12 2022, 09:00 PM
The adjuster on the inside takes a 4 mm Allen wrench.
bkrantz
Feb 12 2022, 09:01 PM
I adjusted the inside pad also to .008".
bkrantz
Feb 12 2022, 09:02 PM
I put a dab of anti-seize on the cap before installing.
bkrantz
Feb 12 2022, 09:02 PM
Don't forget the copper ring gasket.
bkrantz
Feb 12 2022, 09:04 PM
I put all the spring hardware back in.
Oops! Its not straight!!!
bkrantz
Feb 12 2022, 09:07 PM
While I was under the car, I also adjusted the parking brake cables.
bkrantz
Feb 12 2022, 09:08 PM
And then pulled the rubber boots over the nuts.
bkrantz
Feb 12 2022, 09:12 PM
Then onto the last wheel. Like the last one, this had a pretty solid coating of brake crud.
The first application of Iron-X made a big purple mess.
bkrantz
Feb 12 2022, 09:13 PM
After 30 minutes of apply, soak, scrub, and rinse (multiple times).
bkrantz
Feb 12 2022, 09:15 PM
After about an hour.
bkrantz
Feb 12 2022, 09:15 PM
Hour and a half.
bkrantz
Feb 12 2022, 09:16 PM
And after 2 hours, done. All four wheels are cleaned on the inside.
bkrantz
Feb 12 2022, 09:17 PM
And the outside, too. These are certainly not concours, but will do. At least now I get head back to the tire shop.
