newb mechanic - brake issues round 2

[thr_wedge]

I redid all hardlines on a 1964 Comet using one of these. Pretty much the same as using your thumbs, I used the old lines to match the bends.

I looked up your rear brake hose- it doesn't thread in anything. Instead it slips through a hole in the mounting bracket and is secured by a retaining clip.

It should look like this:

RETAINING CLIP... thank you ok that makes more sense, its so rusty on that part I cant tell and didn't want to mangle something else not being sure whether I could get it also replaced. I just tried turning the apparent nut which wasn't really moving, didn't want to cut the hose not knowing it's replacement method either. So the retaining clip should slide out if moved in the right direction then I should be able to slip a new hose end through there, long as the upstream side also undoes fine? AKA if I mangle the end thats replaced by a new hose end/it's not a tee afterall just a mount hole.


I wanted to post my pictures but stupid phone giving me guff, i'll try to get them up today.


All I got done yesterday was bending a line into the right shape perfectly... just to find out I did it backwards. >_< Didnt at first register there was a long/deep threaded side for the cylinder and a shorter/shallower threaded side meant for the rubber hose side of things. So i'm probably going to have to rebend up a new line/afraid it will weaken the other one to undo all bends and redo different direction and radius bends.


Also I just realized that the physical mount that keeps the brake line stand-offed a given distance from the axle doesnt seem to be on the left, only on the right. (which is how I noticed it missing) Not even sure what the part is called but i'm assuming it's important and I should try fab up some piece of metal to do the same job.

Yes- just remove the hose- many times they're stuck... There will be a flat spot or tang to locate the hose in the correct orientation and also to keep it from turning while being tightened. You should also be able to find a replacement retaining clip if it gets mangled.

Don't worry about the long and short tubing nuts- unless you simply can't reassemble and tighten them down the way you bent them.

Whelp cant replace the hose until tomorrow at earliest - theyre not in stock for this vehicle but should be tomorrow morning. So I guess in worst case i'll just hack at the hose even if that's what it takes and thread through the replacement. So just hit all connectors with penetrant again and will let it sit another 24.

Okay I can leave the already made brake line in place if the long/short nuts don't matter - as long as it's something I wont regret later.

To an earlier post when I mentioned using red RTV I was referring to the back side of the brake cylinder to the backing plate - notes I took on this somewhere suggested to do that but I don't remember where I read that. I don't know if this is needed or optional or doesn't matter. Just assumed it was to reduce leaks in some way.


When I get pictures up i'll post close ups of the missing brake line mount since it still exists on the right but not the left, though it's visible in the last pic I posted before showing the hardline. (where there's a clip hanging off the line but not attached to anything) I'm wondering if I can just zip-tie it to the axle or something as a better alternative than it getting snagged or hung up even if I couldn't find a replacement part except in a junkyard or fabbed. I'm sorry I need so much handholding over this but if I dont understand the full purposes of a part i'm hesitant to improvise or do things because realizing I didn't know what I was doing might only come after a preventable accident. >_<

Get yourself some new brake hose clips. They're cheap. Real cheap, like four for $1.92. It's a Dorman part HW1457 so your local parts store can get it if they don't already have it and avoid the $2.90 first class postage charge.

Hard brake line can be secured with most anything that flexes a bit and doesn't rub, such as plastic with silicone RTV to keep it from sliding and rubbing. Or, use a replacement clip like this:

Rubber brake hose is more difficult because it will flex every time you use the brakes, and might move into the tire, coil spring, exhaust, etc. If you can't find that bracket from Mopar or a junk yard, it's not very hard to fabricate one. A little sheet metal (scrounge from an old appliance), a shop vise, a hammer, hacksaw, file, drill, and a little time.
