Rear Brake Calipers and More Pipes

After a weekend without car-time, today I had the whole morning. Unfortunately, it didn't work out that well, so not much accomplished.

Started by finishing off the rear brake assembly. After spending some time trying to understand how to connect the pads with the calipers, I swapped some emails with Steve, from Aries. He really is a great person! I had some difficulties understanding what he was saying but still he kept trying and I finally understood how to assemble the breaks. Fitted the pads on the caliper carrier, placed the caliper on top and bolted the caliper to the sliding pins (with the rubber gaitors). Notice the fact that the oil pipe and bleed nipple are at the top and the handbrake lever is at the bottom.
I noticed after taking the photo that the springs on the pads were out of the caliper, so I had to undo it all and redo with the springs inside. Then did the same operations on the other side. Just didn't connect the flexy brake pipes from the chassis connection point to the calipers because I left the flexies at home.

By the way, after some trial and error trying to assemble the things, I understood that the slots on the caliper piston need to be "straight" so that they slot correctly on the pads. Using pliers, I rotated the pistons slightly.

Went back to the cooling circuit. Finished connecting the pipe to the Y piece near the oil filter. Then did the connections from that hose to the header tank and from the carbs T piece to the header tank. These were easier since I figured out applying some spit on the hose and the connection point helps it slide. But lost over two hours struggling with the braces to hold the pipes in place. The big braces were very easy to use, the small ones are a pain. Left both on the header tank undone and considering buying different ones, like those on the big pipes. Very nice looking header tank, by the way!
