Braided brake lines

[FilthyLuka]

Hey Guys, im after some information.

I did a wee bit of a search on this site and came up with sweet FA. Anyway, im looking at installing braided brake/clutch lines on my GSXR750 ('86). I got quote $300 for the whole shebang, i just need to supply rough lengths and banjo joint angles.

The rear isn't a problem, its pretty straight forward. The front on the other hand :S It has a short line going from the master cylinder to a front block, then from that theres a line going to the left caliper, and a line going to the right caliper. What i wanna know, can i throw away all that shit and just have two brake lines going straight from the caliper, with a longer banjo bolt that has two outlets instead of one. I've seen this done on other bikes, but im not sure if it can directly replace the system that is currently on my GSXR. Can it?

Cheers

Denis

Throw away all shit and have two separate lines. 300 bucks seems about 100% too expensive to moi.

Wouldn't bother with the rear unless the original is fooked.

Its surposed to be better with 2 lines more direct feed to cylinders,just watch the master cylinder banjo bolt thread on my tls was different from caliper thread ,got my lines from TSS for around 200 for the front .

$130 from Mat Mladin in Oz (front brake only). In most countries you can't race with a brake line over the front wheel due to the risk of it being severed.
Hmm red or yellow?

$300 in NZ sounds about correct. You can check the net for cheaper.

2 lines on the front is fine.

Only one is required on the back :lol:

Make sure they are NZ standards approved and marked as such or you will NOT get a WOF.

yea make very sure that they are nz dot std, i've asked at the testing station here ,about ones for the xjr saw them on a uk site looked nice, took infor to vtnz and they said they are not allowed asked how they would be able to tell yup nz-dot std on lines welded joint's, anything else would be failed yea they really do look bugger so pay to really ask first cause a little bit of dosh for nothing if not allowed

Thats my worry about bringing them in from over seas. Anyone know what is and isn't warrantable? I hear that the wof-able brake lines have some form of markings on them that some don't?

Would be keen on some red goodridge lines :cool: But will they be wof-able?

A mechanic mate of mine took another mates 906 Ducati in for a warrent the other day and it failed on brake lines.....it had original steel brake lines that the bike was vinned with but were throwen out for a warrent....go figure.:mad:

Mind you...the same VTNZ threw my flattys CBR250 out because it didn't have banjo fittings on the end of the brake lines.....and they were original factory too.

[AllanB]

Somewhere I have a copy of the document that states the standards they need to meet or the equivalent of. I'll have a look over the weekend and post it.
If overseas lines are DOT or TUV approved you should be fine. TUV is pretty much the toughest standard around.

What i wanna know, can i throw away all that shit and just have two brake lines going straight from the caliper, with a longer banjo bolt that has two outlets instead of one.Sure you can. Brakes don't work in a way that'll let you notice which method you choose though, unless you find one is easier to bleed of course.

$130 from Mat Mladin in Oz (front brake only). In most countries you can't race with a brake line over the front wheel due to the risk of it being severed.Severed by what? If that line gets severed, you've probably eaten something pretty solid anyway, so brake lines are the least of your problems :lol:

Make sure they are NZ standards approved and marked as such or you will NOT get a WOF.There are no NZ standards. NZ is a small country, we don't get to make the rules, only follow other peoples.

yea make very sure that they are nz dot stdThere is no NZ DOT standard, hell, there's no NZ DOT :lol:

Thats my worry about bringing them in from over seas. Anyone know what is and isn't warrantable? I hear that the wof-able brake lines have some form of markings on them that some don't?It's all in the WOF manual (http://www.landtransport.govt.nz/certifiers/virm-in-service/motorcycles-08-v3.pdf) which you can get from the LTSA website :yes:




Brakes 8 - 1 Service and Parking Brake

Reasons for rejection

Mandatory Equipment

18. A flexible hydraulic brake hose (including
connections):
a) is leaking brake fluid, or
b) is insecure, or
c) bulges under pressure, or
d) is twisted, stretched, chafed or
e) external sheathing is cracked to the extent that
the reinforcing cords are exposed, or
f ) has metal connections that are excessively
corroded, or
g) has an end fitting that is not attached to the hose
by means of swaging, machine crimping or a
similar process (Note 6)


Fitting of or modification to:

Aftermarket brake pads, linings, and hoses:
- In service requirements for condition and performance must be met.


Note 6: Hose end fittings that can be undone using hand tools are unacceptable.




So, what are they saying?
- You can fit any aftermarket hose you want, whether it displays some standards or not
- The hoses you fit must ideally have crimped ends, although the letter of the law it outlined in note 6.

Just buy a quality brand like HEL, Galfer, Spiegler, or Goodridge and you'll have no trouble.


If you're interested, typically hoses manufactured in NZ will have to meet the standards SAE J1401 or ADR7/00.

Sweet! Cheers for that imdying.

Last bit of info i need though, the front brake calipers have straight connectors for the brake lines, not banjo's (see attached photo). Can i replace that with something like a 90 or 45 degree banjo? Or further more, if i just go on that site that was listed earlier in this thread, and order brake lines for a 1985 GSXR, will they sort it all out for me?

Cheers

In a word, yes. The straight ended factory ones seal against the caliper with a copper washer right?

yup, something like this:

[imdying]

I can't tell from the pic, but I've seen the odd old GSXR caliper in for servicing now and then. Pretty sure they seal on a copper washer, which means they're machined correctly as a sealing face, which means you can use banjos in place of them.

Some odd (for motorcycles) things have seats at the bottom of that hole, which the tip of the hose seals on. Most of those too will take a banjo bolt with copper washers, as generally they machine a face that is suitable for sealing on the caliper anyway, but always pays to check and double check when you're dropping a few hundred on parts.

[mouldy]

60 degree banjos and bolts will replace the straight connectors ,run 2 lines up to the master cylinder and get a double banjo bolt with bleed nipple for the master cylinder
