Upgrading Brakes to Z32 - Torque Member Question

Post by **dsagers** » Tue Oct 18, 2005 1:33 pm

Considering upgrading my brakes to the Z32 calipers. From the FSM I see that all four of the Q45 calipers are held in place with a bracket called a torque member.

Of all the ads for Nissan big brakes, none even mention this bracket. Will I need the bracket for Z32 calipers? Can I use the one from the Q45?

Search about the upgrade. Wes has done this to his Q and did a write up on it. If not im sure hell be posting soon anyways.

Hey buddy!!! Glad your ready to start doing the Z32 brake upgrade!!!

The Q45 and Z32 use different types of calipers.. The Q45 uses a sliding caliper, which as you noticed, the caliper is held in place by a bracket which bolts to the hub... This makes it very easy to replace the pads, and they are also a very efficient design and take up less room, which is why most cars now adays use this design... They also have all the pistons on one side..... They call it a sliding caliper because the caliper can move relative to the bracket (and the hub).. It moves on the slide pins... basically what it does, is when you press the brakes, the inner brake pad is forced against the rotor, and as it does this, the calipers slides which then in turn forces the outer brake pad against the rotor.....

The Z32 uses a fixed caliper, which the whole assemby mounts to the hub... there is no bracket... The caliper stays in the same position relative to the hub... the pistons simply move the pads toward the rotor... These are a simpler design and can often be modified for use with other rotors and things like that.

Well basically you got more than you bargained for.... however the bototm line is you dont need a bracket....... Just get the caliper....

Thanks.

At first thought I was in for a big pain changing the calipers, but with this info I can see it will be rather easy!!

I guess I am dense.

To what does the Z32 caliper attach? It must be mounted to something to hold it in the correct location realtive to the rotor.

Don't quite get how it can mount to the hub, unless you mean the hub housing assembly.

It mounts in the same holes as the caliper brackets do on the factory Q brakes.

If you take off the Q calipers, then remove the 2 bracket bolts, you can remove the bracket from the spindel, then you can slide off the rotor. When you put it back together, the Z32 caliper bolts straight to the spindle, in the 2 holes left from the caliper brackets.

It is really quite simple. The only difficult part is the brake lines. I am still waiting for my conversion lines.

hes right... i guess you could say with the Q brakes the calipres and mounting part are 2 units, and the Z32 is one unit.

OK guys, thanks for drawing a picture for the blind.

Let me know how you solve the brake connection. Bunch of short links on stock G50 to isolate the movement of the hydraulic lines.

Anyone change to the Z32 master cylinder, or is it necessary?

Conversion lines?

As I recall, the fitting end of the Q brake lines are different than the receiving end of the Z32 calipers. I think Wes said you can file down the Q end some and it will "set".

I think what red and I want to know is what is the proper brake line specification for each wheel position, including fittings, so they can be made to order?

Post by **elwesso** » Wed Oct 19, 2005 5:12 am

Brian, i think im going to tell you to SEARCH!!!!!! BECAUSE I ALREADY MENTIONED IT... Naa, thats ok ill explain it instead of just telling people to search.....

the 240SX uses the same body side fitting as the Q.. Many aftermarket places make stainless conversion lines for the 240..... with the 240 body side fitting and the Z32 caliper fitting.....

however, on the Q, there are 2 mounting points on there, whereas on the 240 theres only one. HOWEVER ANOTHER interesting thing i learned isthat on the SS lines for the Q, they only give one mounting bracket on the lines..... That simply means, that buying the Q45 SS lines and making them work is no more productive than getting the 240 lines.. you gotta kinda play with them to get them to fit, but mine are in there and its all fine and good... put on about 6-7k on the car since then and no problems...

If you want the least ghetto setup, stick with the rubber Q lines, and cut the banjo bolt down.. The next best setup would beto get the 240 conversion lines... that is the easiest solution, but like I said theres only one mounting point.. I ran my lines thorugh the other mounting point and put some tape on it so it doesnt scratch the braides.....

Brian, dig up my Z32 thread and all will be revealed.....

What he said.

I bought the 240 stainless conversion lines for front and rear. $115 shipped to the door. Not too bad, except I haven't received then yet.

As soon as I get them and see the build quality, I will either referr yo uto them or warn you to stay away from them.

Real good price Jeff, most places I've seen want ~$79 + shipping for the fronts alone and some want close to $90.

Can't wait to see some pics.

Wes, don't want to do surgery, want them pre-made. That's why I requested the detailed specifications.

Thanks.

Post by **Rex** » Wed Oct 19, 2005 6:59 am

Brian - these appear to be pre-made and with a single chassis mount

http://www.240sxmotoring.com/24z32brcoli.html

While the Goodridge show 2 mounting points on the Q45 front lines.

The question is, what would only 1 mounting point mean? Flopping line?Rubbing line? Those would be bad, but are they really a possibility??

Post by **redmanfx** » Wed Oct 19, 2005 7:54 am

So you used the Q Lines and made them work right? I mean, that's what I thought everyone was doing anyway. I must have missed a post somewhere because I don't remember a whole heck of a lot of discussion on the SS lines. Just remember us talking about making the Q SS lines work.

Rex, that's kind of my question also. Thanks for a little light.

Post by **elwesso** » Wed Oct 19, 2005 8:23 am

the thing is, i talked to Greg, as well as squeefoo, and he said the goodrich lines only come with one mounting point... im pretty sure thats what greg has...

Either way, your either going to have to deal with something.. either your going to have to live wiht only one mounting point (which ive proved isnt a big issue, i inspect my lines regularly and theyre as new to date), or your simply going to have to cut a little off the banjo bolt.. I did this on one of my rear bolts, as they use the banjo's in the rear, and it worked fine...

My lines dont flop...

Why do you people insist on making this SO HARD... JUST GET THE LINES, PUT THEM ON THE CAR, AND IT WILL WORK, HOW MUCH MORE DO YOU NEED TO KNOW!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Anyone who is scared of "making something work" should NEVER EVER EVER EVER consider modifying a car.. bottom line...

It's not a question of fear, it is of detail specification, and not wanting to hack.

So I guess some like to know all they can instead of just enough to get into trouble.

No company could make brake lines with only the information in your posts.

Post by **elwesso** » Wed Oct 19, 2005 9:31 am

not trying to beat a dead horse... But this has been done before, and before me!! So because it works for one person, you dont think it will for you??? I didnt do anything special to mine besides bend a few clips to make the holders stay in tighter.....

Regardless, id be happy to see you go with the Z32s instead of some of those other brake kits that are a rip off, IMHO.....

Cool, so you did use the Q lines. That's what I thought. That's what I had intended on doing before I decided to hold off for a while. You're right, it's no big thing to get them to work anyway.

You have mail.

No... I used the Z32 240 conversion lines...

looking back thats probably the route I would have gone... I really am not convinced that the lines really make that much difference.

I bought Russell lines for Layla, and have close to 100,000 miles on them, and they are fabulous. No issues, and I didn't cover them. They had all the factory mounting points, I recall.

On Lola, where I am using the Z32 calipers, I bought lines from this guy:

http://cgi.ebay.com/ebaymotors...%3AIT

The auction was for fronts only, but he added the rears.

They are en route to me, so I have no information on quality, and can not recommend them. I should be getting them this week, and will post my opinion.

If I was going to settle for rubber lines, I would have just modified the factory lines but since I was upgrading to SS, it just made sense to get the conversion lines.

I love these discussions, it proves that there is interest in these cars beyond fixing idle problems.
