The photo below shows the front brake lines off the Raptor. There is a single flexible from the master cylinder joined to a rigid large 'T piece' that has each end P clipped to the rear of the bottom yoke with a flexible to their respective calipers. After market replacements e.g. HEL use a T piece in a --| orientation bolted to the RHS of the bottom yoke - see second pic. In this configuration the top goes to the master cylinder, the lower to the RHS caliper and the middle using a large flexible over the wheel & down to the LHS caliper. Although this allows for suspension movement in the lines I find it (visually) messy & unbalanced. I was trying to replicate the original solution's routing using flexibles but the shortest length they do is 10 cm plus there would be too many connectors for my liking. So does anyone know who might be able replicate the original set up using both rigid & flexible lines.
Have you tried Venhill, https://www.venhill.co.uk/hydraulic...q3TJ2TN1KDNQR3D9X_PkIvIpYAJAxm7NMY5gaYW6d_97Q ? Andy
I looked at their 'line builder' and they also don't do any lengths smaller than 10 cm but I haven't, yet, contacted them to see if they could do a bespoke build for me.
try goodrich or earls, goodrich will probably do a hard line solution bespoke. Failing that you could try Pirtek if there's one local to you, or alternatively a fabricator. Are the flex lines swaged directly to the hardline or do they screw in? Pirtek and earls will happily make new flex lines and re-swage onto the existing hardpoints. that hardline just needs a good go with a dremel or some scotchbrite and then get it re-zinced if it's not stainless steel.
They're certainly not screw in so must assume they are swaged/crimped - my confusion because the caliper & master cylinder line connections look different.
Hel will do custom lines if you ask them. Could you not go flexi from R caliper, flexi from L caliper to a 3 way connector block then flexi upto master cylinder, would that work?
You could have a look at Goodridge products as an off the shelf solution. I used them when I did an ABSectomy on my BMW R1150. https://www.goodridge.co.uk/ PS Shouldn’t this be in the Raptor refresh thread?
I recommend ATEC in Brackley. That sort of thing is what they specialise in. https://atec-autotechnik.com/en/downloads/
As per the second image in the original post that is how HEL do the routing with the 3 way to one side but it all looks messy & unbalanced to me. And as there are only two mounting holes for the existing J clips a more central placement of the 3 way would require another hole to be drilled out.
I was thinking of that but wasn't too sure whether it's viewing figures would reach a sufficient audience, ho hum... Plus it might prove more useful to others as a separate thread (title)
Yes sorry I didn’t see that image until after I posted, but you could just rotate the connector block so that the lines go in either side of it and then the line out the top to the master. That way it would be central. So in that image with the red lines just swap the master line and LH caliper line over.
Andy, hel will do a custom line to your specs, but personally I would refresh what you have. that hardline is a nice thing and I’d just replace the flex lines, or at the most have some threaded portions brazed on there so you can replace them easily in future. I didn’t ask, why do you want to replace the lines? is it just the surface finish on the metalwork?
As can be seen in the last photo the banjos/crimps on the caliper end (plus the master cylinder end) are quite badly rusted and as it is the lines themselves could do with a little extra length say 10/15 mm. I'm quite happy with the hardline finish and as you say it's a neat tidy fitment. I like the idea of brazing.
I meant central as in mounting the 3 way more central on the yoke - but note it can't be completely in the centre because of the headstock.
Andy, any decent hydraulics place will be able to re swage new lines on to your existing fitting and to your specification, so you have plenty of options.
