Anyone know anything about disc brakes?

Thanks

PSA:

Do not under any circumstance use the metal ‘epic bleed kit’ adapter with your Shimano brifters.

Do use the plastic friendly nylon one.

You risk rounding the port using the metal one over and over again. This is expensive. And it’s also almost impossible to get a replacement lever right now.

As you were.

How often are you bleeding the poor things?

But the bolt that caps the reservoir is metal. Just be careful and don't overtighten stuff.

It's made of really soft aluminium with only a 2 or 2.5mm hex which strip out way before you can damage the threads.
It looks like the metal adapter there has wrench flats, and a sharp steel thread. Different kettle of fish. Metal =/= metal

Hopefully this will be addressed in the new shimano releases .

it wont, when shimano uses a plastic bolt they want you to be careful and only use the plastic bolt. Another example is NDS preload on hollowtech 2

Does anyone know of shimano ultegra level hoses in stock anywhere? Or a forum approved non shimano set? Switching group over from one frame to another, the front will def be too short.

Arm as far from the caliper body as possible is what I had best results with.

Appreciate it, thanks, will give that a go.

Spent £130 odd on a pair of sram discs a couple of weeks ago just come to fit them and there weren’t any lock rings, is that normal ?

Don't know for sure, but different hubs can take slightly different centrelock lockrings, depending on axle standard. Think they generally come with the hubs. Every time I've needed a set someone has come up trumps on this forum.

Thru axles or not can affect which type you can get away with too.

Yeah I realised that when I came to order some. That being said, the limiting factor in all this is the size of the splined interface not the axle size it would be easy to make one to fit any axle size, the 15 & 20mm one appear to be the same too.

whatever for?

It's more the fact that the thread on the metal one is 'too aggressive' and because it's going into plastic has over time cut across the threads and then caused them to detach themselves from the levers. Yes i was also doing the reverse until click before inserting but 🤷‍♂️
The nylon is rounded rather than pointed so won't be able to cut. Basically as @chiroshi says.

How often? these were on their 3rd bleed technically. But the 3rd bleed took a few attempts - new calipers. So maybe 5 X inserts give or take.

Mineral oil disc brakes should require bleeding pretty much never. The fluid remains viable longer than the service life of the lever. Or at least as long as it takes to spot the next shiny thing and flog the bike and make it someone else's problem.

I'm using Hope 5mm hose without issue: https://www.sjscycles.co.uk/brakes/hope-disc-brake-hose-5-mm-per-metre/. Tried with both DA and Ultegra.

Bought ultimately because i couldn't get any BH-90 because Amey is hording it all.

Also BH-90 is BH-90 so consider XT, XTR etc too...

These were 1yr old levers, on their 3rd bike.

I need to stop getting new Frames and get Bikes instead huh?

That's pretty much what the industry has decided :)

Recently worked on a friend’s 2015ish Spez hybrid. Hubs rusted, chain rusted, rings badly worn, tyre tread gone, headset the slightest bit crunchy (but couldn’t remove fork with half a can of WD40 and a 5lbs mallet so we left it in, ha). The brakes? Basically perfect, just needed new pads, and rotors.

Most old bangers I see come with some variation of black gloop instead of oily pink stuff. It works, until it doesn't.

Oh yeah, we had to rebleed the brakes on my Stayer when rebuilding it last year, what came out of the system sure wasn’t pretty.

So what the fuck am I doing wrong here then?

It’s a hope rear hub 12mm bolt though, it’s sram splined disc, which arrived without a lock ring. So I bought a 12mm disc lock ring and I’m now trying to fit it but there is almost now clearance between the axle and the lock ring and I can’t get the tool to fit. It’s a stand Shimano lock ring tool.

Do I honestly have to remove the axle to fit a the disc ?
