Awesome thanks.

Thanks, good info there.

That video states "not Marzocchi 40mm" so not sure how much help that would be. It's pretty frustrating because I'm a mechanical engineer so can do most things once I've been shown once but just don't have anyone to show me lol

TBH I got annoyed with it honking so just saw red and ordered a new disc and pads. By plunger which bit do mean?

Thanks very much, any idea what weight oil I should be using? I weigh 80kg (on a bad day) and like bouncing around. Also how much oil to fill each leg? Admittedly I've not watched the video yet as I'm at work with poor mobile internet so if it's covered there apologies.

Yeah my thoughts exactly. Fingers crossed.

OK it's been pressurised for over 22hrs now and no leakage anywhere?! I guess all I can do is fit my new disc and pads when they arrive and see what happens.

It's a 2012 with AJP master cylinder, that likely to have that issue?

I need some main fork and dust seals ('12 GasGas 300 with 40mm Marzocchi forks), most of the trials websites and eBay don't seem to state the seal brand so I assume they are just selling cheap generic seals? The Pyramid Parts website does the whole kit for £17 but I've read that the seals can be junk. The only other branded seals I've found are SKF but they are about £50 IIRC for a full set of main and dust seals. So what are you lot in the UK buying?

OK, have cabled tied the front brake on tight and covered all the hydraulics joints with paper towel, will check on it again in about 20hrs from now.

That's a good idea, didn't notice any oil no as my garage is carpeted so the carpet would have soaked it up also reservoir was pretty full tbh.

Not done this before, how do I do it?

No I've not found the issue yet and yes good shout about sorting the system with the old disc and pads in I'll definitely do that. Just checked the bike and its still heing pressure from when I bled it yesterday, going to be pretty hard to diagnose a leak that only sometimes leaks.

While on the subject what's the best method of bleeding the front using a syringe? Pretty sure I've don't it OK but never hurts to see what other people are doing.

Just taken my front disc off for the first time (bought the bike used) and found some silicone around each of the bolt spacers. Would this be to stop squeak/vibration? Basically I went to take my bike out yesterday and found my front brake had no pressure at all even though it was fine when I last rode it a few weeks ago. So I bled it out but in the process the hose popped off and spilt fluid on my disc and pads! So, had a go at them with some wet and dry but they are squeaking real loud and not gripping so I got in a mood and ordered a new disc and a set of pads. So what can I check when rebuilding with regards to the fact the whole system just lost pressure and also should I be adding silicone to the disc bolt spacers again? FYI the brake was super strong before it lost pressure.
