Post subject:  63 rubber brake line install/removal
How do I remove the old front rubber brake hose?
I am looking at a new one and one end has male right-hand threads and the other end is female left-hand threads.
What is the installation procedure?

I can't find any pictures or description in FSM.

I've never changed one. :oops:

(9" front drums)

Think they're both right hand threads, but on my 64 (with front 9" drums) it was really obvious and I didn't need the manual :twisted: :wink:

The male end went into the wheel cylinder and the steel brake line went into the female end.

Side note: The replacement line I got was slightly shorter than the original line and I had to remove a little bracket thingie so that the steering would turn lock to lock without pulling on the brake line.

So I install in that order - to brake cylinder first, then to steel brake line?

I see there's a clip holding the end connected to the steel brake line.
To remove the old one, do I unscrew the fitting on the steel brake line, remove the clip holding that end of the rubber line, then unscrew the hose from the wheel cylinder?

Sorry about the easy questions.
It's dark and rainy here and my back is keeping me from taking a good look.

Tomorrow or saturday I'll take my prescription muscle relaxant, jack up the car, swap the hose and bleed the brakes.

There's no safety rules about working under a car while under the influence of flexeril is there?

Yep screw the brake line into cylinder, then deal with steel line.

It's been 2-3 years since I did it, but I think the clip just pulls out with vise-grips (but that could be my toyota truck)...........

All I remember was that everything seemed obvious...........

I think it may be easier to loosen everything with the clip in place (see comment about truck above)......

If you are replacing 1 side -- might as well do the other-- --something to do with the flex in the old line causes braking problems.(pulling to one side--1new hose & 1 old hose).
for removal-- soak your connections with PB blaster -- loosen the frame connections first-- then at the wheel cylinder-- really simple job but if rusty will cause some grief just the same!!.

Cut the old hose and use a box end wrench or a socket to remove the old one, but not to install the new one.

Thanks everyone.
Mcnoople's tip is a good one.
I got the new hose on.
There was a copper washer at the end of the hose that was removed from the wheel cylinder, so I used it with the new hose.
For now, I'll stick with one new and one old.
I read somewhere that the old hose expands under braking pressure while a new hose doesn't (or not as much), so the pressure in the cylinder with the old hose is less than the other side.

Just one question:

Who stole all my small wrenches?!!

But the pressure in a closed hydraulic system is the same everywhere, so I don't see how the 2 sides can react differently.............

That sounds right to me. Maybe it was a dream I had.

One reason to replace both sides is for peace of mind.
Still have the single-pot master cylinder.
I still haven't gotten around to upgrading my brakes and rebuilding the front end. Got Condon's book - just need to find a donor car in Washington.
