Topic: New addition to the family! Gotta rebuild the brakes...

If you're worried about gunk....

take some brake cleaner spray and spray it into the lines, then take an air nozzle and shoot some compressed air in there.

Cleans them right out.

Cool, I'll have to try that. Where would be a good place to buy new brake pistons? Can't find them on partsnmore or z1. Honda has them but they're $107 each.

You have a 750, the world is your oyster when it comes to brake pistons.  Look at phenolic ones- they'll never rust/pit.

I just read somewhere that 80-82 750f calipers will fit my bike, confirm or deny?

[nobody]

So I got the 81f calipers, was only able to pop one piston out of each caliper. Any ideas how to get the second one out? Do motorcycle shops have some sort of piston extracting tool? Secondly, The calipers were missing two pieces (a rod and a bracket, the others are pictured below), I've contacted the ebay seller but chances are that they got lost somehow. Any idea where I could pick up these pieces without having to buy another caliper? I could probably check the junkyard but they might not have the 80-82 750f. Could they be bought individually? Oh, and upon further inspection I found a huge cluster of disconnected wires... FUN!

IF you cannot find replacements...

Let me know and I'll make them for you.

Grab yourself some padded channel locks and pull the other pistons out. Should be relatively easy.

Thanks Havoc, the pistons inside the 81 f calipers are perfect, the bore isn't too bad either. I'm repainting them while I wait on the rebuild kits.

So I'm putting this bike on hold. The brakes don't fit right because the wheel won't sit straight, I'm going to rebuild the wheels and see if that fixes it. I gave it new plugs, fresh gas, clean oil and it wouldn't run anymore. I think the gas may have gone bad. So I pulled the carbs, broke a rusty throttle cable in the process and a rusty choke cable. Pulled the float bowls off and inspected them but can't see anything blatently wrong. I sprayed some carb cleaner and some air into tiny parts but have yet to reconnect them as I no longer have cables to make them work...

All in all this project is making itself a noble adversary. Since I'm moving in a few weeks I've no money to continue working on it right now. Once I get my new shop set up at the new apartment I'll start it up again. I'm just going to dive into the neo classic cafe racer build instead of trying to make it road worthy and get it titled right now. Maybe I'll put the 74k on the front burner and see if I can't fix the tranny first. Either way I'll probably just start a new thread in the projects section. Thanks to those who've answered questions and tried to help me out with this thing. I'll be back soon with more progress to show. (hopefully)
