So Shimano r785 di2 levers with a new front flat mount RX4+ caliper. A few weeks back it was fitted and bled and all lovely. 3 or 4 rides later it started seeping out of a connector and contaminated pads and discs. Arse.
Thought let’s start again - all new connectors at the caliper end and let’s do a quick bleed. Funnel in / full syringe of mineral oil attached / bleed blocks in. Go to push fluid through - but won’t push through. Odd. Tried different combos of lever adjustments but nothing.
Oil is happy to piss out everywhere when you disconnect the syringe. Every time. But no oil will go in. Checked the syringe is fine and it is - squeezes oil out lovely when not connected. I’m stumped.
Ideas?
Ignore me, I’m a dick.
Syringe and fluid cup on different brakes?
Sorted?
Yep - syringe on front brake - funnel on back brake. When I realised that I’ve just packed it all away and will start with a clear mind!
I was raging about something else and clearly wasn’t in the right mindset as normally I’m decent at bike mechanics.
No one else in the history of humanity as ever done that....honest
Bet you realised your error just as your head was touching the pillow 😂
Been there before 👍
I was changing my boy's cassette on his road bike the other night, I slipped and managed to split my chin open on my work bench. Felt a right dick.
I also fitted a Thunder Burt to the rear of my bike ready for my Badger Divide ride. It broke two tyre levers getting it on. When I stepped back to admire how I'd aligned the logos with the valve I realised I'd fitted it backwards. Arse! Its still like that, 1 week after the Badger. 😆
You're not alone.....
It’s like Northwind’s upside down fork 🤣
Sometimes you do something incredibly daft and just think wtf was I doing 🥴
I once had no end of bother fitting some Panaracer Fire DH tyres. Must’ve broken half a dozen levers in failing to get them on.
Because they were for 24” wheels. I had 26” wheels.
Glad I'm not alone in having brain farts, thanks all 🙂

If you want to see subtle brain fart, a moderately mechanically experienced but not 100% clued in friend of mine spent about 2 hours fitting some road tyres to a colleagues bike, punctured two or three tubes and broke "several" tyre levers. Then couldn't get them to seat properly on inflation. So they got left overnight, at which point they were ranting on line about how hard tyre X was to fit on rim Y fitted to bike Z.
Except bike Z takes 630mm rims.
And the tyres were 622.
So even getting them on the rim was a huge achievement.
well at least you didn't try to inject fluid at the caliper end without first having connected the hose at the lever end, you'd have to be really stupid to do that
Or put the funnel on the back brake before opening the bleed port on the front...
