Front Brake Hose Leak

[Ickis]

I did a front a brake job including calipers. I was also going to swap out the brake hoses (because I hate brake leaks and wanted to keep the hose and caliper manufacturer consistent) until I realized stock brakes hoses aren’t long enough for my jeep. Before I figured this out, I had already disconnected the driver side brake hose from the hard line. Upon re-install, caliper connections were bone dry, but this hard line hose connection was leaking.

It only leaks when applying the brakes. I included the passenger side connection picture which I didn’t disturb. I found the driver side really tough to disconnect, but didn’t seemed like I damaged anything. I got a few turns out of the hard line side before I ended up screwing the whole hose instead of the connector.

How do I fix this? I’ve got it tight as it will go.

The flare must be bad/worn. A new flare in the line would probably fix that, but the OEM lines are steel and hard to flare, so you may need to replace the pipe from the master to that bracket.

On your passenger side you may need a clip to hold the joint into the bracket. An E-clip would push in place but I don't know what size you'd need.

I ran into this about a week ago. My brake line got hit with something and kinked it. I re-flared mine with no issues. So just re-flare it.

I’d inspect the flare surfaces (hard line and hose fitting) for any scratches or burrs. But at that point reflaring the hard line is just one step further.

Sounds good. How do I re-flare it? Are there any guides to follow? I am a complete noob on this frontier.

You can rent the flare kit from Orielly's (you'll get your money back when you return it) and look it up on YouTube.

Before attempting to REFLARE the brake hard line; I would disconnect and inspect the existing flare for burs, debris on the flare or inside the flex line fitting.
Reflaring is not as simple as creating a flared fitting.
The automotive brake lines are double flared; which takes some experience to get it right.
I have seen automotive mechanics require several attempts to get it right so it doesn't leak....
IF you decide to try reflaring; I would suggest you practice on a scrap piece of brake line before trying to reflare the drivers side hard line.
You will only get one or two attempts before your brake line is too short.

Found some YouTube videos, 1A Auto has a good one. Wondering about sizing and how to get a new end connector. Do they sell generics at Oreilly too? And awesome, didn’t know they rented that.

Good idea. I will try this first. In the end, the cost of a new hardline is likely cheaper than taking it to to a mechanic for a flare, so I might as well give it a go and then replace the hole line if I mess up. Lines $100?
