Sorry, no. I doubt you'll find anything so explicit advertised. You need to do some detective work. First, for low volume car production makers use as many parts as they can from existing production runs. The same is true even for high volume cars like the Mini in many cases. For functional parts like brakes that the buyer doesn't see, no-one is going to make a set of shoes, or drums or hoses etc specially just for that one car - they'll use something that's already in high volume production.
You can start from the Reliant parts lists (check out the Fifers site, NOT Bug Stuff but look for Parts Lists) and you'll see the Bug hoses are listed as number 20301 front and rear. Next step is to Google this, and search eBay - don't bother, I've already done this for you and it's not there. BUT you do know now that front and rear are the same.
Next is to look at similar Reliant models of the 1970s, see if they shared any common parts - again, don't bother, I've looked, and Reliant gave different numbers to the brake hoses on the Kitten, Regal and Rialto - whether these are actually the same spec hose but with a different number for each car model, or whether they are actually different hoses, it's not possible to say. But you do sometimes find the same part number carries over - I've certainly found this between the later Scimitars and the Middlebridge.
So next step is to look for cross reference tables - there are several out there, but with the Reliants being such small numbers many don't list them. For example, Mintex do an excellent chart, but they only list the Scimitars. So... keep looking... and you'll find www.brakeworld.co.uk/brakeworld/appguide/webhome.htm
. Now this company seems to have been in administration since early 2017, so I don't know how long this site will be maintained - so don't hang about!
If you click on 'brake hoses' on the left side, and then on 'Reliant' you'll see it lists the Rebel, Robin and Rialto. I don't know which of these is closest to the Bug but I'd reckon the Robin, since that's the recommended donor car for the Webster. Looking at the Robin hoses, it lists 2 - HH117 and HH236. If you look at the specs, you'll see the only difference between them is the length - one is 305mm long, and the other is 360mm long.
The question is: will either one fit your car? Take off your hoses and measure them. If they are around this length, and have the 3/8 x 24 UNF male to male fittings then you're in business. Remember, you can have a hose that is a tad too long, but don't get one that's too short or the steering/suspension travel may rip it out!!
Now if you click on the tabs, Buyers Guide will list which other cars these fit (Land Rover seem to use a lot of the same parts as Reliant, probably becasue they too got locked in to Girling) and the other tab, Cross references, will give you a load of equivalent part numbers used by the aftermarket suppliers like Quinton Hazell, Borg & Beck, etc. Importantly, in the general specification details, you'll see the "O E Ref", which is the Girling or Lockheed etc original equiment part number.
For the HH117 this OE Ref is 241689. If you now Google "241689 brake hose" you will get a load of hits for Land Rover brake hoses, and you'll see they used the same hose on loads of different models. Now all you do is choose a model and look that up on the Goodridge site and see if they list a braided version.
Personally I would recommend phoning Goodridge with the OE Ref number and talk to them about your application, as they will tell you how best to get it. They don't sell direct to the public, as far as I know, but they were happy to tell me which spares stockists they supply most.
The other option is to start googling the aftermarket suppliers parts numbers, with 'braided' included in your search. This will obviously be rather tedious as each supplier uses a different number - but many sellers include limited cross reference numbers in their eBay listings so you may turn up something without too much delay.
Yet another option is simply to remove your existing hose and send it to one of the many hose makers listed on eBay and elsewhere, and get 'the same but braided'. This may well be more pricey, but may also be much easier. Venhill is one such but there are several others out there.
