Helpful vid thank you. Though I wouldn't use side cutters as they'll damage crush the ptfe and cause a leak over time. Tape and use an angle grinder with a cutting disk.
holy crap i have trying to assemble my -3 hose like bigger hose (burr free and stuff) i got to say its nice knowing what i was doing wrong...going to head to my garage and build some lines right now...screw work i got a race car to finish
I have a pressed ss brake hose kit on my car. One of them started leaking. So I learned from this and other similar videos that I can just make my own ss brake hose cheaper than the ready pressed ones, which are now super expensive, thanks to the inflation. So I bought 1m an3 hose, shortened it down via taping and angle grinder and installed the fittings to the ends. Everything looked just fine. After I installed the hose to my car and started braking, both sides of the hose leaked from the fittings/olives and that's it. I bought a regular rubber hose and not a single problem! I think I'm done with these type of hoses. The pedal feel is worse but they're not overpriced and also, there is no risk of leaking. Never has been.
NEVER CUT BRAIDED HOSES WITH SIDE CUTTERS!!!! You squash the pipe and weaken it at the fold point on each side. Wrap it tight with insulation tape and use a cutoff disc. Don't take my word for it, ring Goodridge.
Just a quick question, wouldn't it be better to cut it with a cutting wheel on a grinder? Wrap it up in electrical tape before and then cut. And the tube inside wouldn't be collapsed
secrete here on why this works with PTFE small hoes and not standard steel braided small hoses... is the design of the nut's to move toward the end.. and not the nut going toward the middle. It pushes the braid down instead of wanting to bunch up the braid. On standard Rubber- braided lines the nuts are universal for Steel and Braided... and.. if was a flare at end like these nuts it would likely work. IF they; Like PTFE desing the nut was installed first before cutting.... and forced the braid down as it tightend on the fitting. this would certainly work. As desined though with Rubber Braided. the nut bunches up the braid's and is a royal PITA. You can mitigate past that issue with superglue on 6an and larger braided hoses before tape; then cutting. On braided hose ALWAYS, no matter how good you are ai it... wants to flare out some. hence why superglue helps.. For steel braided.... it is the ONLY way to do it successfully IMHO!!! BUTTTT On 4an and lower.. forget it.. that wont help you. Sill frays out just enough that you will NEVER get the nut on Steel Braided. The common generic fittings sold for rubber braided lines; without the end of the nut having a magic flared end; like PTFE nuts; on small lines. it ain't going to happen. With superglue and Nylon Braided.. I bet you would be ok on small lines. I've not tried 4an nylon braided; only 4an steel braided; with ZERO success . Have done 10an nylon and 6an steel successfully with Superglue method.
NB This is using braided tube without a clear plastic coating on the outside, and getting the olive onto the inner can be very tight fit. Likewise the spigot can be a very tight fit.
@@CarBuilderSolutions Sure - just wanted to point out that some does, and if it does have the coating it needs to be peeled back and cut off for an inch or so at the start. Your video is very helpful.
Hi just wondering about what you say about the plastic coating. will the stainless still be under this plastic coating after you peel it back an inch?@@davidscott3292
Industrial hydraulic hoses are made similarly but finally the clamp on the flexible is swaged. What pressure has this type of fitting been tested to? I thought this type of system was not legal in UK?
Fine. But it's not usual to have hydraulic oils in a plastic pipe line since components of the oil may be solvents for that polymer. How about a braided steel brake line with a black neoprene sheath and male or female connectors either end? This would be reliable and flexible.
The PTFE lining is perfectly made for use with oils/petrol. Pretty much any serious competition car you see will have these fitted to them rather than rubber. For brakes they give a sharper feel due to no flex like standard rubber types and are a much better solution for for custom fuel lines, as the rubber lined cheap stuff permeates allowing fuel to evaporate and the smell is horrendous.
Hello, i think this is perfect for me, but with what do you start from the normal line to go from there with the steel braided. It's the last piece of line on the rear right line of my Peugeot 206 GTI 2001. And ill think ill will replace the left one as well. Please let me know? Kind regards Eric
Hi awesome video. Quick question, I have a Toyota 4Runner that uses M10x1.0 fittings with an inverted flare. Are these going to work for my application?
My good man, I've been looking all over ebay for that male swivel union and I can't find anything, can you please share some info on where to find it? Pretty pleeeeease! ! ! !
They wouldn't be DOT legal in the United States. Pre-assembled braided-and crimped- lines would be, but not these. I doubt they'd be MOT legal in the UK as well.
+Salvador menacho To answer your question, Yes! This type of flexible hose using a PTFE tubing with a stainless steel woven cover is used on motorcycles now, as well as boats. On boats with I/O drives (Internal engine / outside drive) they use stainless steel tubing along with this PTFE type pipe covered with the SS mesh is required to lift the drive up or down to get the correct angle while boating to keep the prop in the water. A high pressure pump inside connects to this pipe to flex thru the range of motion. Many custom builders, Tech's and DIY'ers use this line on custom builds and race cars or just for show. Without checking the SAE website, I believe system pressures can reach 3,000 PSI, but tested to higher pressures as engineering rules usually to be safe exceed the max system load by 3 times the working pressure. Your good to go, but what you are doing by watching this video is research to see materials, process and use. This is smart as automotive techs, in shops or dealerships have the best results when they follow best practices. Sad the guy didn't respond to your post. Retired ASE Master tech.
I have edited my last comment, 4 out 4 joints leaked, this idea is really hit or miss. The principle is good, but in practice they are awful. To get my bike back on the road I had to pack the inside of the fittings and around the olive with a two part plastic padding. I then tighten the joint leaving the two part plastic to go hard and seal around the minute gaps that were causing the leaks.1 hour later, brake line purged of air and no leaks. If you have the same problem it's the only solution if your stuck with these fittings. I would have liked to have seen this guys joint bench tested with fluid. This solution is tight, it does not leak. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rQKE2JithzY.html
Have used these fittings for years never had a failure and all were and are still fitted to completion cars where brake fluid temperature and pedal pressure are very much higher than any road use
+Jaroslav Maksimiuk This type of PTFE piping with SS mesh covering is used on cars, boats, motorcycles, air planes, etc. Anything that will experience vibration and movement where a hard line would fail over time. The pipe like this, may have a little expansion during pressure cycles, but is limited & protected by the SS covering. SAE approved for brakes, fuel and other applications. Many show cars, restorations and tech sue this type of piping when building a project and will last for years. Only some discussion of ethanol mix fuels has pointed out that some level of brittleness may occur over time due to exposure, but use on "Flex-Fuel" lines from the factory, like GM. Hope this helps. Too bad they did not reply earlier. ASE Master since 1978, retired.
Your NEVER SUPPOSED TO cut steel braded line with side cutters your supposed to use a cut off wheel you are creating a weak connection! Don't do it this way it's wrong and look up the right way to do this
Using flexible pipe the entire length of the car causes you to loose the pedal feel, think of it like this when you press the brake pedal the hoses move a little, now if you did it to an entire car when you press the pedal much of the energy would be used to move the hose, thus less effecient
