Sounds good to me! Just a few more pointers: You’re going to have to bleed the system for sure, so don’t be too worried about losing fluid. Hopefully you have enough excess hose to make such a repair. That’s quite a bit cut off. The insert (brass pin) is delicate. Careful when pushing it in, as it may require a bit of force — it likely won't just slip in. ...

Well I'm all done - some things that would be better done differently. Use a quality 8mm spanner. Mine was a bit sloppy, and I've rounded off the nut that enters the caliper. It took a lot more applied force to do up, because the olive needs to be deformed. Expect to do a brake bleed. I took care to work up high, above the level of the lever, and ...

The pressures necessary in any disk brake setup are extremely high, many in excess of 2000psi [SRAM 4234 Rev A(2012), p4] so require a spirally-wound fiber core reinforcement to function. Because this fiber reinforcement core can never be clear, even if the fibers were themselves clear such as glass (which is a common fiber used) you will not find any that ...

The usual approach is to disconnect the lever nut, cut off the hose just below the factory barb, and then feed it through from the caliper end up to the lever. Then you turn the bars all the way and hold up the hose next to the lever and mark the spot you'll trim to for optimal length. Cut, slide on cover and nut, install new barb and olive, reconnect and ...

The J-Kit system is designed for this. https://www.shimano-tec.com/course/view.php?id=1088 It is possible/likely the brakes you have purchased are j-kit (easy hose joint system), in which case there is a cap which can be pierced; the brake and lever are not connected on supply, and the installation is easier.

Your question is unclear; a frame would normally be just a frame, without calipers or levers. From your question it is therefore not clear whether you have the levers or not. M3050 is a basic caliper with no special features. If you buy the cheapest set of Shimano brakes, which would be MT200, then this would be the same quality as M3050, but would come with ...

The BH59 or BH90 will work. You will need to trim the hoses to length (as they always come excessively long), and install them with the correct hydraulic fittings. There will be a T-shaped insert that needs to be hammered into each end of the cut hose, a brass barrel-shaped piece that slips over each end, and a special nut that holds everything together and ...

Shimano BR-M3050 calipers are from the Acera line: https://bike.shimano.com/en-EU/product/component/acera-m3000/BR-M3050.html Normally I'd point you to the Shimano specifications page which tells you the brake hose kit required, however the BR-M3050 calipers are missing. I suspect that the BR-M3050 calipers are new and replace the BR-MT200 calipers in the ...

There is a unifying theme with bleeding Tektro and similar brakes: disregard the written procedures, don't trust the contents of any bleed kit to give you what you need, aggressively modify the kit parts, and make up your own rules. I follow manufacturer instructions faithfully when they work, like for Shimano, but for the Tektros and Promaxes of the world, ...

I'm only going to answer an aspect of your question; you can apply it to your brake how you wish. Firstly, Certain Tekro models are fiddly to bleed but also feel like they need bleeding if the pads are worn down, so if you haven't put new pads in, I suggest you do that first. When something like this comes into a commercial workshop and this amount of time ...

Your underlying question here is "how to tell if there is air in the lines?" and transparent brake hose would probably work well for that, if it can hold the pressure. There are water-traps for air-based systems - I wonder if there is such a thing as an air-trap for hydraulic systems. It would have to be at the highest point in your hose, or ...

I just got my front brake of the same model bled to a point where I'm happy. There's still a bit of sponginess, but the bike will stop. A few tips I found helpful: As Nathan said, put zip ties on all barb fittings. The tubing slipped off a barb twice before I smartened up and slapped some zip ties on there. Time to clean up two puddles of oil now...grrrrrrr ...
