Where would this be, and what would need replacing?
Had an advisory on My mot for corrosion.

The brake lines terminate inside the rear wheel wells then go to a flexi to the calipers. Could be this. Or it just could be the unions on the flexi, they do seem to rust.

Honda uses connection blocks between the hard lines and flexi hoses which are prone to corrode.

Civics use a 6 flexi hose setup with 2 up front and 4 out back.

I'd hedge my bets it's one of the awkward to get to, rear blocks that's been reported.

Good luck.

Interesting findings, my four door, 2.2 needed a 6 line kit.
My 2.2 ex is the same, I have four lines on the back.
Are the connection blocks hard to replace, any idea on part numbers?

I've sorted the fronts, just got to do the rear discs/pads and lines.

Got some oxalic acid to flush out the rust.

@Huxley, one of my rear blocks was a complete PITA and took me longer to get out than fitting the rest of the kit!

Fingers crossed that yours will all free up with little/no effort.

Let us know how you get on, you'll have plenty of time now that we are in 'lock down' ;) - unless you can work from home or are a key worker...

wire brush and corrosion protective coating should to the trick
That's what I'm thinking, some oxalic acid with a brillo pad and stonechip paint and acf50

I could work at my mothers. No one lives there so shouldn't be a problem I'd imagine.

Any idea on a supplier or part number?
Mot said rear brake union corrosion as an advisory.
You say it's hard to remove but I do have small and large impact guns.

As for time sadly I have little thanks to being a food supplier, we'll be one of the last to close.

I wouldny use stone chip was thinking more of a corrosion spray like acf 50
as they might class the high build of stone chip as not being able to inspect

Good point, thanks for the heads up, got some acf 50 coming, heard nothing but good things.

Just realized the brake block I'm on about is part of the line so have it already.

Wonder what's involved in removing it, sounds like a fun job.
