Yeah the pistons have some sort of coating... POS.
I have a couple of spares if you want them. I also have seals and scrapers if you want them. Not available from Brembo... liability issues. Steve at Bevel Heaven makes up kits for these, doesn't supply scrapers. You can get the scrapers from Honda, GL500 IIRC.



I just did a set of Yamaha TZ calipers. Worst I have seen in a long time, and irreplaceable.
I ended up drilling a hole in the caliper, driving the piston out from the back, then welding up the hole. A bit of filing and paint, looks as good as new.
Another trick is to drill a hole in the piston and thread it. Screw something into that hole to use as a puller.


... I once launched a piston out of a caliper with air pressure, went across the shop and hit my washing machine, cracking the door. $640 later for a new door and seals....


What color are you using for RED? I need some touch up paint.

Yeah, they were plenty loud!! Got the attention of almost everyone in the shop when each one went.



I wrapped the piston and caliper in a shop rag so when they went, they didn't go flying. It worked. Farthest one of them went was a couple feet down the work bench.



Just got done with chores for the day....gonna head out to the garage and get the second caliper rebuilt. Then it's on to the master cylinders......sean

That's good to know. AFAIK, you can get the Brembo kits from Gotham Cycle and an eBay storefront. I can't remember the name of it. Bevel Heaven is pretty close by to where I live.



I appreciate the offer on the seals and spares. I was able to get my pistons out and they, along with the seals and scrapers are actually in quite good shape. Just covered in scale and jello like old brake fluid. All good after a trip through my ultrasonic cleaner.

I didn't want to resort to that level of brute force as I wanted to preserve the Gold Line calipers as much as possible.



TZ calipers? Are you building a TZ? If so....pics plz

oooohhh.....that's 'spensive!! I can relate though. I once worked in a body shop. I finished a paint job and wound up with a really bad run that required me to re-shoot a fender at the very least. I took off my paint hood, and hucked it on the nearest work bench.



All I heard was a really loud SNAP. I looked over at the bench....and there, with a nice big star and crack was the windshield from the very truck that just got a run in the paint booth. It wasn't $649 but I still had to pay for it.

I'm actually changing the color so I didn't try to get any red. I got my paint matched (for the color I want) by the House of Kolor rep at my local ACE Hardware.



Aside from trying to get the OEM red from Color-Rite and paying too much for it, I'd check around and see if you have a local HOK rep to do the same for you.



My apologies if I'm not much help in the red paint arena.....sean

Didn't really get anywhere with the bodywork that arrived. Just unboxed it so nothing really to show off. The only thing I did do was I drilled and mounted the new tail section last night.



Mostly to test fit, but also to see what support needs to go under the seat unit where the rider sits. It's a fairly big gap from the frame tubes to the bottom of the fiberglass.



There is a kit available to make it work but I'd anticipated there would be a support issue. I ordered some tank mounting rubber for the later 900SSie thinking that would suffice. I was wrong. Not going to work.



Anyway, here's a shot of the tail mounted with the new saddle sitting in place:

Got a few more things done in the last couple days. Last night I mixed up some JB Weld steel reinforced epoxy repair.



This is not the stuff you get at Walmart in the two tubes. This stuff comes in a double/siamesed syringe type affair that expels the correct amount of each part when actuated.




Using this stuff, I repaired a number of small things that I'd been preparing for. First, I'd ground out the crack in my alternator cover from the inside. After spraying out the newly grooved out crack with brake clean several time and letting it all flash off, I waited until it was all really dry. Probably 20 minutes or so. Then I applied the JB Weld to the groove. Hopefully this seals the crack and I can reinstall the alternator cover back on the engine.


At the same time, I repaired a crack in the crank case from the same area where a chain derailed at some point in the life of the bike. Then, I did the same to one of the speedometer studs that secure the speedo head to the binnacle.



I managed to get the speedo head reassembled tonight, and installed back in the binnacle.




Also painted the speedo needle in orange to make it more visible. I don't know what color it was before but it was white like the tach needle when I got the bike home. It was a royal pain to take apart and get it all cleaned up inside. Then reassembling the lens and bezel onto the speedo head.....royal PITA. It is now done though, so one more step in the right direction...........sean
