Does anyone have a spare oil plug from a 400/4 on the points side. Part number 15332-300-000 called 'cap B, oil path in parts manual please. I've googled for it but it seems unobtainable from partzilla, CNSL, DS etc.
Regards Paul

Many thanks for the replies folks, I'll have a look at 400fourbits website, luckily only need to replace one 😉

Apologies for the confusion, it's not actually numbered in the parts manual, but I believe Bryan is right! It's the V shaped spring that sits on the main jet.
Regards Paul

You were lucky, when I bought my 400 I never noticed the bleed nipple was missing off the front brake, on strip down had to bite the bullet and get a new caliper as someone had filled the threaded part where the bleed nipple went with liquid metal. I tried to clear it all out but it was too far down into the fluid ways, how they bleed the brakes I have no idea. My first thoughts when I saw the missing nipple was, not a problem drill out the old one best I can, stud extractor to remove what was let, not a problem, recut the threads, how wrong I was.
Jeez, that sounds like a PITA 😀

Well done PX in finally getting the piston out - these victories along the way make it all worthwhile.
Cheers Ted - one giant step for man and all that! Front fork rebuild next whilst some parts go to the sandblaster. But still looking for bits that were missing 😀

Once again thanks for all the advice and comments. The pop when it finally came out was very satisfying, but it put up a hell of fight! 😀

If you can't get it out with a good grease gun then I would think the oil ways in the caliper are solid and must be cleared first. A good
high pressure grease gun should be able to do 1000bar which is far far higher than the pressure generated in a braking system.
We used grease guns at the pit on hydraulic nuts and locked them off at just under 1000bar.
Moorey, that's exactly my thoughts, so I got the Dremel out with a fine bit and that sorted it. Thanks everyone for your advice and comments. The caliper is now sat in evaporust overnight and I'll check it's condition tomorrow. I also drilled a small hole in the piston so I could free it with a drift, which worked a treat.

This has never failed for me.
Get the caliper, turn it upside down, flat side down. Now get a 10mm drill and drill a bloody big hole in the dome section, get a 10mm bolt and just drive that bad boy piston right out of there. Now you say, that's left a big hole in my caliper but fear not intrepid adventurer the solution is at hand.
Get an old style sixpence and just braze that over the hole. In case it leaks then just braze a old style penny over that, if that leaks then I'm sorry but I can't help you, you're just crap at brazing.
This advice of course only works if you have a handy supply of old style currency, don't try this at home kids.
I had considered drilling and tapping the piston or trying to weld a bolt to it. Unfortunately I'm all out of old coins and my brazing is worse than my welding 😀

Ive never had the grease gun fail, but then i do use the air one at work, also you can get a caliper complete with with mounting, bolts, adjuster and pads from amazon for about £66. Put cb 500 caliper into the amazon search but scroll down as there are several and prices vary a lot, if you leave out the bracket i saw one at £51
Bryan, if all else fails that'll be my final option Cheers

Heat almost certainly won't hinder it and may benefit, there's not much risk and I'd be inclined to heat the caliper in an oven rather than direct with heat scource.
There's essentially nothing inside them, just the piston and seal and they're pretty robust anyway.
Best wait until the wife goes to work for that one 😉
