Can you patch a leaking brake line?
You're going to need an adhesive, like tape or rubber cement, to patch the leak in the brake line. Most auto parts stores carry a special hydraulic system or brake system patching glue that can help. Just be careful none of this gets into the brake line, as it can cause serious damage to other components.
What can I seal a brake line with?
Thanks! It's best to stay away from Teflon tape on any brake/fuel system. Just use any good pipe thread sealant (paste) with Teflon or PTFE, and only on pipe fittings.

Are Compression Fittings safe for brake lines?
In addition, compression fittings are known to leak when used on brake lines, causing a loss in brake fluid, and ultimately failure of the braking system. You cannot, under any circumstances, use compression fittings to repair the lines on a public transportation vehicle.

Soooo I installed all my lines, bled everything, ended up with that much sought after "firm" pedal, checked all fittings for leaks and found 4. Each one (as you might remember if you read the installing disc brakes on 6 lug hubs) (or whatever the hell it is called) came from the factory fitting in the residual pressure valves I installed.

I take it the leak is where the flare adapter threads into the residual pressure valve. If so, this is a standard 1/8"pipe thread and can be sealed with teflon tape, or at least this fix has worked for me in the past. If the leak is where the brake line attaches to the flare adapter you'll have to re-flare / replace the line.

I agree with John on no dope/tape/sealant of the double flare fittings.
Zig Member
Yes, this is on their end, not mine. The fluid is coming out of the fitting that screws into the body of the valve.

Did you flare the ends yourself? If so, it may be your flares. Hard to do correctly. Ask me how I know.
john1 Member
I wouldn't worry about using teflon tape on the pipe thread end of the adapters. Max pressure to the front brakes will be around 1000 -1200 psi with the rear brakes being about half of that.

I would not put any faith in some gunk on the threads...not a science thing, but have done it to get me home! Recently, went thru some vintage lines on a trailer and 54 panel...found out that now there are all kinds of fittings, sizes, and configurations or ji-rations. Some in, some out, some doubled, some flat, some long, some short...

Does locktite seal flares?
Locktite on threads wont seal an inverted flare.the flare itself seals where it comes into contact with the cone inside the female part of the fitting. Locktite just keeps the nut from coming loose and indicates tampering if necessary.
