New project CB750F1

It looks like your arm bushes are a two piece design , so they still do the same job . My brakes were toast , every piston was siezed except the front left , it was only partially siezed . I soaked them in CRC/WD for a week and ended up useing air pressure to blow out the pistons . Scared the crap out of me when one piston let go and hit the roof of my shed . Be carefull if you use air or even hydraulic pressure , put something in the caliper so they dont fly off . I would recommend using a japanese kit for the seals . After the fun I have had with mine , it is worth the trouble of sourcing good or original parts . It does suck that now the price of master kits have more than tripled in 2 years , phew ! Mine did have a halogen headlight replacement already from the states . I did have to replace it as we have a front running light and drive on the left in OZ , so the lens was wrong . I got mine from the canadas but you have david silver in your neck of the woods , so he should have a replacement . But you can buy a 7 inch replacement from car parts stores that will fit .

Hi Hinksy, finally worked out how the swinging arm pivots and yes mine is standard and all as it should be.
Seized calipers I fit a grease nipple to the fluid port and pump the pistons out that way with a small trigger grease gun and slowly increase the pressure until they're out, rear caliper is a bit of a performance with the twin cylinders, you have to get one out then refit that one and clamp it so you can get the second one out, even this way they come out with quite a pop!!
Spent a couple of hours today with my spare rear brake caliper with the broken bleed nipple, when researching on line for solutions came across these little beauties https://www.ebay.co.uk/itm/335331662783 they are a game changer and worked a treat, I even had the right tap in my toolbox so it was just a case of drilling out the broken nipple then drilling 9mm, then tap the M10 x 1 thread and screw it in with sealant and a copper washer for good measure.

New problem with rear brake caliper, I'm missing the following part for my rear brake caliper 43213-371-006 spring pad this secures the pad pins in place in the rear caliper, without this spring there is nothing stopping the pad pins from falling out with obvious bad consequences! these are fitted to F1 and GL1000 so don't really understand how they can be unobtainable but can't find any stock anywhere.

I was the same with mine . Had no pad springs or shims , didnt even have the other stainless things that protect the caliper from rubbing of the pads . Had to look high and low and found one here , one there , bit by bit over two years . Even found out that with a little trimming , you can make a 79 front spring clip fit a 77 . The rear brake looks very much like a brembo knockoff , so maybe have a look at there spring clips https://www.ebay.com.au/itm/3650889...BRDKG8&hash=item5500ff06f2:g:ITkAAOxybi9RdgFW

Thanks Hinksy a couple of good tips there.

Turns out you don't really need the pin spring as the cover plate on top has ears to stop the pins falling out so all assembled ready to fit when the time comes. New stainless steel pistons fitted so no more rust!
You can see the bleed nipple insert in place

Just come across this YouTube site when reading some other posts on here, check out Hackaweek he covers all you need to know to buid up a CB750 from just the frame to a complete running bike! I haven't watched them all yet but this seems to be a great resource.
