Wondering if anyone knows of a brake fluid resistant thread sealant?

obviously thread tape is a poor solution (turns to mush)

I have some loctite hydraulic thread sealant, but Im not sure on the differing properties of hydraulic fluid and brake fluid?

Anyone have any advice on which to go for?

Brakes shouldn't need a sealant... ever

Unless your holding a plastic bottle together in which case I use white Sikaflex 221 I think it is

But as I say... you don't need sealant with brakes as they seal on the flares on the ends of the pipes

Lets just say there is a minor frOck up...

When repositioning the holes for the caliper fluid inlets, they were drilled straight through and tapped...

I was extremely worried that the threads wouldnt seal for the exact reason Datto metnioned (the taper at the base of a brake line thread seals, the thread just holds it there)

Turns out I was right, they leak out the threads, which is bad...

So in an effort to resurrect the calipers without having to either block and redrill next to the current holes, OR find and rekit new calipers ($200 worth..) I figured a hydraulic sealant would be worth a try (hey, hydraulic systems see WAY more pressure than brakes do)

Change the fitting and use a copper washer on the outside instead of a tapered seat, like a banjo fitting?

Have donesome machining of the fittings, grabbed some copper washers and am now crossing everythin that it works.

Thanks guys.
