PMQ, since the brakes work on extremely high pressure, like 1800 PSI, any expansion of the hose will result in a "softer" pedal feel, and more pressure, to get the same result. Granted, it is not a real big difference, but I felt it, and like the firmer, faster pedal response.

Wes, Do you know if the hard line connection, and the clamp half way down the line is the same on the 240 as the Q? The caliper fitting could be the same, but the length, and connection end to the car hard line might be totally different. Keep working on your end, and I will keep working on my end. If the converted 240 lines fit the car, that is the best answer.

Imay have to just buy some Goodrich Q45 lines, and replace the connection at the caliper end, with an -AN fitting that fits the calipers. Of course, if a better idea comes along, I am game.

Pff, that's nuthin. I've got Air HOse that handles more then that

I'm serious. YOu can get ANYTHING made by commercial suppliers. They can make you a brake line that is tougher then the SS stuff, expands less then the SS stuff, etc.. get my point?

The thing about buying premade stuff for the Q45 is that it's so damn expensive, and there's no reason for it. The only reason I can figure is that it's because it's a $50k car so you should have alot of money.

If your going to go to that trouble why not just have some full custom lines made...

Im in the process of figuring out if the 240 lines will work..... That seems like our best bet...

My point exactly! THen you can hand pick ALL the materials that go into the line. If you want 10kpsi hoses, you can, 20kpsi, no problem... fittings, anything you can imagine and then a few xxxx more...

Wes, If you decide to get a custom set made, go ahead and get a couple sets made.

Make sure the car end connector with the clip, and the mount half way down the line with the clip are part of the hoses, so they work well with the car.

Just get the Wagner Master Catalog -most places that have one will probably let you look it over for awhile while you take notes and see what fits what. The hose dimensions are in there.

I have to do it all the time to get stuff to fit if I can't wait for a couple of days, or if they don't make the original anymore.

The support in the middle of the hose will slide if you shoot it with silicone (use the pure stuff), then put the wrap on.

THe local hose supplier has a few of those catalogs. They're very informative. Just by looking through it you can learn what the different types of hose materials are best suited for what application.

Does the catalog cost money? Where can I get one?

SS lines are NOT expensive, I can get the conversion lines for well under $100.

I have a set sitting on my worklbench waiting to go on the 240.

And there IS a difference between SS and rubber lines, more than just pedal feel, let's not belabor that point any further. Otherwise, professional race teams would use rubber lines.

I"m not talking rubber lines. I'm talking dedicated Hydraulic lines. That shat is tough as nails.

I was talking to Wes earlier and it seems that the custom set will cost about the same, maybe a little more, then the SS lines. I don't know though, something about having extremely tough stuff, custom, appeals to me

Part of the attraction of SS lines is they have abrasion/cut resisitance from objects that can be kicked up fom the road/tires. It's not just expansion control.

I know Home Depot doesn't have 'em

Auto parts store, if you have a commercial account they'll order one for free (new). If you get to know the guys in there (buy enough stuff) they'll give you an old one when the updated ones come in. You can prob. look if you need to cross ref. something. About 2" thick, you can use other books too as long as the dimensions are in it (of course).I keep forgetting to grab a newer one, mine is from the '80's.

The braiding can be cut/nicked and lead to localized swelling, put on some spiral wire wrap or clear vinyl tubing with wire ties. Heath said his came with vinyl installed... mine didn't.

just as a suggestion, but somebody should contact Stillen and ask them about these lines you all need. They sell the Skyline conversion kit for our Q's at a price of $1,500 and I am almost positive they told me that they included the special SS lines. Call Stillen and ask for Kenny....he is the only knowledgeable Q45 guy there.

If you don't mind, before you put them on the 240, compare them to the lines on Quella, to see if they will work in my application. I am in no hurry. I will be turning the front stock rotors, which gives me a few more months of driving before I do the conversion. I would definintely appreciate it.

It was kinda embarrasing to let Dennis drive Lola with warped rotors. They just started vibraing last week, and I haven't been driving her. I don't notice it much, because I hardly ever use the brakes, myself (maybe once or twice a week).

I have been praying for you, Stacey, and the rest of the family.

I have the meausrements from the Q45 brake lines...

Thanks to Dan at Infintii of scottsdale he pulled them off the shelf and measured them for me......

All measurements are from fitting to fitting..... So the end of the banjo to the end of the other fitting

Front is just shy of 23in, 22 3/4 in

Rear is just shy of 12 in, 11 5/8 - 11 3/4

If i can get greg to measure his 240 conversion lines then we can see if those will work.....

I have a feeling theyre the same since nissan doesnt like diversifying things like that.....

Greg has some special (that others sell) that convert the 240 hard lines to Z32 caliper fittings.. The 240 fittings on the hard lines are the same as the Q as far as i know......

So theyre basically 240 lines with Z32 fittings on the end.....

Make sure the mounts half way down the lines match up, otherwise you will have to tywrap them to the strut, and that will look bad.

Greg should have his old lines from the Q (I still do) that he can place side-by-side with his 240 converted lines, and take some pictures for us.

I talked to Alan again, and Im sure he hates me a lot by now...

The 240 lines should be OK to use, he said he was pretty sure the body side fittings were the same...

Im going to order my lines this week, the 240 to Z32 conversion lines... and hopefully get this done.....

Brake lines and speedbleeders ordered (at a PHENOMINAL price, thanks ) and now i just have to muster the energy to put them on and live with the other nagging problems the car is having.....

Theres no such thing as a perfect Q45 so why not live with certain things....

Don't forget to post some pics, when you get them in. I am now in the process of polishing the calipers and smothing out all the bumps. Hopefully, when I paint them, they will look as good as the G35 Brembo calipers.

I did too, however; I just weighed them and they weigh 16.25 lbs. Under the 17 lb min. that Q45 Tech has calculated to be the least mass to avoid warpage. They are 280mm X 30mm drilled and slotted from iRotor and 1 has been cleaned up to 29.7 mm -down from 30.2 actual starting thk. Makes me want to measure the holes and slots to see if I can find that .75 lb. (I'm sure thickness/ density comes into play) .5mm removed to true it up so i have 2 cleanups left in it, with about 10 - 12k mi in them. I think QTech is right about the 17lb mass issue.

Yes, everything is very clean, with heat sink grease added. I think I'll buy the next ones based on weight. Oh well...

BTW the cooling vanes determine the direction and/or placement of the rotor. These are unidirectional, with the vanes square/perpendicular to the center. Not as efficient at shedding heat as directional. They were cheap though...

Copied from previous posts... I performed a major brake overhaul a few weeks ago.... Steel lines put in....Paid $89 for a set of Russell steel braided.



"Well.... after an intensive web search, I located a set of Russell Brake Lines for $89 + Ship which is the best price I could find out there (most are $95 - 115). That's considerably cheaper than the dealer rubber hoses! (not knocking the dealer product, they lasted 15 years!) It's shipping from Miami tomorrow. Just about all the other sites didn't have the product and stated that it would take two weeks to get it in (Q45 stuff doesn't sell too fast)!

Just thought I would share the site since they seem to be the cheapest around (when you can get through). I know there must be others with aging brakelines thinking about this. If you call them and don't get through...call again as they are slow to return messages."

Here is the direct link to the hoses...

(If anyone calls, ask for Luis... his customer service was excellent)
