3 Meters /9.8ft Black Bike Hydraulic Disc Brake Hose Tube with Olive Connector Inserts Set Accessory for DIY Bike Replacement

So I got a pair of ebikes and have been performing some upgrades as I find the right ones or the right price on one and I’ve been able to review a fair number of bike parts along the way. I first upgraded the bikes from mechanical disc brakes to hydraulic 4 piston caliper disc brakes. I think they perform similarly but the force required to make them perform the same is so much less it gives confidence in your ability to stop which makes going fast feel better. The brakes came already filled with brake fluid and brake hoses attached to the calipers. They still needed to be connected to the levers I assume so that you could route cables through the frame or wherever you need to route them. My second one went better than the first but because the bikes were folding type it required some circuitous routing of the rear brake hose and the hoses included were a little shorter than I would have liked. They reached but I wouldn’t be able to fold the bikes without cutting all the zip ties holding the hose to the frame. I looked into using new hoses and the only difficult part is cutting the hoses to length and inserting the end piece into the hose without crushing the hose. You are building a brake line from scratch and there is a fair amount of pressure so the pieces have to fit tightly together. Anyway I found a tool for cutting the hose and inserting the ends, so I was finally prepared to try building my own lines(now I understood why the lines were preinstalled on the new brakes. That was when I found this kit that allowed me to make longer lines for one bike. I had also gotten some experience with bleeding the brakes pretty quickly(hydraulic brakes work better but require regular maintenance that is a little more involved than mechanical brake maintenance with the risk of contaminating the brake pads with the fluid, meaning you should always remove pads when servicing. Just a drop of fluid won’t ruin the pads, but you may want to replace them due to the squealing you’ll now have). So I’ve become a bit of a bike brake mechanic in short time and now my cables are the length I wish they were originally.
