2023 Vado 5.0 SL Leak at lever end of brake hose - barb damaged in shipping?

[Jencuya]

I am putting together a new old stock Vado SL1 5.0 Step-Through for a friend who had total hip surgery a year ago and is having a hard time stepping over her old bikes. The bike was shipped from NH to PA in good condition, and well packed by the bike shop; but when I attached the handle bars I noticed a hydraulic oil leak from the L/front side brake where the hose attaches to the brake. I opened up the bleed port and, sure enough, the reservoir was dry. There was evidence of oil on the corrugated cardboard the brakes were wrapped in, so I think the problem is limited to the brake end, no evidence of oil on the caliper end. I removed the hose from the brake and found out that the seal on the barb looks damaged, as is the barb itself. I have a bleed kit coming this week that includes the small parts for the brake hose. I have attached a pic of the open end of the hose with the barb and the opening is more oval than round and crimped--it looks like it might have been bent in transit, and that was the cause of the leak. Since I don't know what a new barb would look like, I'm curious if anyone in the forum would know what the opening should look like. Thanks!

You would need a new olive and hose pin.

Wow! Thanks for the exploded view--I couldn't find one in my research. So it's the olive that's obviously damaged; I didn't try to remove the old one from the hose to see that there were two pieces because it was so jammed on. No wonder it leaked!

Cut 1/2" off of the hose to eliminate where the old barb was. Leave at least 1/2" of play. There should be some hose slack in the frame.
Install the nut, threads towards the cut end.
Install the olive, tapered side towards the nut.
Install the barb using the tool. Don't crush it. As soon as it's flush and you feel resistance, stop.
Screw the nut onto the lever/caliper. Tighten it snug, not tight. You'll mangle the olive if it's too tight.
Get a bleed kit and maybe brake fluid appropriate for your brake brand.
Remove the brake pads and install the appropriate brake block.
Bleed as directed, either cup and syringe or two syringe.
Test the lever for squishyness. Once the blocks hit the rotor, the lever should feel solid.
After bleeding, wipe down the caliper, remove the blocks, and reinstall the pads.
Adjust the caliper so that the rotor does not drag.
