Drum brake setup
Hi, I am just completing the rear brake (drum) installation on my velocity and would like a couple of things confirming if possible...
How should the handbrake cable exit the drum? Currently its a quite an acute angle and will rub on the bakeplate. Is this right? I am just a bit
worried about wear on the cable (and the SVA man!).
The other concern is the flexible brake hose. The ones that were supplied have the banjo bolt type connection to the drum but there isn't
enough room so I have fitted it the opposite way round and the banjo bolt is now screwed into the copper pipe end and the normal bolt end into the
drum. Are there any problems having this pipe this way round?
Thanks!

To be honest that doesn't look right to me.
A few questions
1: What is the banjo bolt screwed into or is the flare nut screwed straight on to the banjo bolt?
2: If the flare nut is straight onto the banjo bolt is the end of the banjo bolt shaped to seal on a flared pipe?
3: Have you tried it?
I don't want to say it's not right but unless there is an adapter in there that you can't see in the photo then I think you'll
be luck if that seals.
If the flare nut has bottomed out on the bracket which would be the only way to get the banjo to seal on the copper washers then you cannot tell if it
has tighten the flared pipe up correctly.
Conversley if the flare nut has tightened on to the copper pipe you don't know how tightly the banjo will seal on the copper washers.
Hope this makes sense I'm quite tired and could be talking rubbish
Regards
Davie
Wish I could do those short straight to the point replys!!!!

Copper washer under the banjo shouldn't really be onto a painted surface either.

I haven't tried it - i thought it best to get some opinions first. It definately isn't how it should be but there isn't enough
space in the hub carrier to get the banjo bolt. I suppose I'll have to do the sensible thing and buy somemore flexi hose with a differnt
joining arrangement.
Any comments on the handbrake cable?
Thanks!

Sorry but I have to agree with daviep's thoughts.
On the face of things, it's not looking like that banjo union will seal.
One thing for sure. The SVA tester will probably give you a staight fail. If he is in a very,very good mood he may let you disconnect the pipe to
prove a seal exists on such an unorthodox arrangement.

where's the outer on the handbrake cable?
is it sierra? if so, the steel spring outer will stop any wear issues on the cable
that banjo bolt just looks........wrong. i can't see any way it'll seal unless it's been machined to fit with seriously tight
tolerances....or you're incredibly lucky

NO WAY! can I see that passing.
Unless someone corrects me, bolt for banjo is hollow bolt with and hole in the side that will allow fluid to go into the banjo, seal made via copper
washers.
The bolts screw into a tapped hole e.g. in a caliper.
I cannot believe there is the correct flare on the bolt to accept the brake pipe end since they were neve designed to be fitted that way
You need to get a brake hose with the correct ends - should be around a tenner - not major money at all.

Banjo bolt goes to the Caliper, not to the pipe.
Make sure the surface on the caliper is flat, and clean. the use a NEW copper washer, or anneal the one you have, or it probably wont seal
properly.
The Banjo does not fit to the inline fitting like you show it in your Pics.
These pics are of Luego's Demonstrator (loads of pics in my archive. I took them for reference when I built mine).
 
Rear N/Side H/Brake + Pipe 2
 
Rear O/Side H/Brake + Pipe
EDIT:
Just noticed you have drums. You probably need different flexi pipes with male threads both ends. Those ones in your pics are definatelythe same as
what I had for my discs.
Another idea!
Also with a set of brackets you can convert to discs at the rear, but you would need a different handbrake cable as well.
I would have a chat with Luego to check you have the right flexi's for the rear Drums.
Make sure you tell them you have Drums not discs.
