Brake pipe - flexible? NRC7801

AJofShabby · Aug 15, 2020

Hi all

I’ve bought a tired 110 which needs a new brake line from the driver side brake to the passenger side. There were no pre-made replacements for NRC7801 that I could find so I bought a “flexible” brakeline. It’s arrived and it’s about as flexible as wood. It’s essentially metal tubing that’s one length. I’ve bought some pipe bending pliers. Am I best to:
a) remove the current brakeline and try to replicate the same and the feed the line around the front of the car

b) buy some true flexible braided brakeline

Any advice gladly accepted.

thanks

I suspect the brake line you are referring to is not a flexible, braided pipe, but a solid one. When you say runs along the front of your landy, do you mean along the front of the bulkhead? The brake pipe to front passenger wheel runs from the fluid distribution unit, up the bulkhead towards the screen, travels along the back of the engine (clipped to the bulkhead) drops down the side of the heater box to the chassis rail, runs along the chassis rail to a fitting where it then joins the flexible pipe that runs to the caliper.
You could try disconnecting the original and see if you can get it out without bending it. If so, you could make your new one up to match and wiggle it in. It'll be a struggle though

If you still have all the fixings in place, you could just follow them. Straighten the pipe out, slide it along the back of the bulkhead and then bend the left and right sides in turn to follow the fixings.

Thanks. The description says flexible, so I thought it would be thus! Anyway, nothing else planned today.

Just had a re-read of your post and realised that my pipe travels across the front of the body, under the radiator, not across the bulkhead. That would be way too easy. It looks a right PITA to track. God bless LR and their standardised procedures.

Is it copper brake line? I did my first one a couple of months back, replaced the original rusty steel one. I was surprised just how easy it was to form round bends to follow the original clips.
Oh, and mine goes under the rad too, it was still easy peasy.

Oh. Just found the breaking point of the flexible yet non-flexible line. Another on order....Snapped trying to fashion the u-bend on the driver side connection. My fault as I shd have started at that side and worked my way across.

Doh! As you’re waiting for some new pipe, you may as well order a cheap little brake pipe bender/former, perfect for doing the u-bends.

I’ve actually found a correct pre-shaped brake line that I will now have to try to install ...

Just a thought, but could you not just measure the length needed and have some stainless Goodrich brake hose made up ?
I have had this done on motorcycles in the past where you had one hose from the brake master cylinder to a spliter then two hoses to each caliper, this was replaced with two Goodrich hoses directly from the master cylinder to each caliper.

Just had a look at Pioneer, looks good

Hi

yes, thought about that and will contact them. Pioneer website looks interesting if only they could get rid of the messaging box! Thanks all

I ordered the brake line from LP Parts. As can be seen here, NRC7801. Part number 16. A preconfigured brake line. The second image shows what arrived....

That's like phoning Domino's for a pizza and being sent the ingredients. I don't even know what to say to them!

Go to your local motorbike shop and ask if they can make a copy with Goodrich brake hose.

AJofShabby · Aug 20, 2020

I’ve contacted Goodrich to ask if they can make one up. Tks.

Get a small, cheap brake pipe former. It’s the flaring on the ends that’s crucial. You’ll need to to some bending anyway to get it around the books and crannies of arches/suspension turrets etc.

Not quite just ingredients because the fittings are in place and the ends are flared, by the looks of it through the packet.
I’m surprised your first one snapped? What was it made of? What’s this one made of? I replaced all of mine with cupronickel pipe and I bent them by hand.

That is what I did with mine, Bought a flaring tool, some fittings and a length of pipe. Cupronikle is very soft and easy to work with, I didn't even measure the pipe I flared and fitted one end, worked the whole pipe reel along forming the shape as I went and then when I got to the wheel cut it to length and flared that end to fit.

Just thinking. Did you just say ‘can you make one up for me’. Or, did you say ‘can you make one up with the exact dimensions and bends already done for me’. Otherwise you may end up back where you started with a straight bit of pipe with the fittings on and ends flared.
