He has grinding when the brakes are cold he said

Mm on inside not used and pads on the outside overlapping
The rotor edge

Spacers just removed the play

xtcnrice

I see. Has FFC responded to a new custom bracket? I'm wondering if there's any 2G out there running the RL calipers on another bracket (FastBrakes for example).

Running out of ideas, but perhaps Sav is ok even with the inside mm because he's using blank rotors.

chuonthis

I will check out the pads and rotors soon. I'm due for an oil change so I will work on the car.


As for now I have not have any problems with noise or anything. I am really happy with the setup. Sorry I cant give you guys any info because I purchased the entire kit from Robbp.

Thanks, i greatly appreciate it. you could be having issues like me, but not generating noise due to different pads/rotors

I just want to get it resolved for people who have issues, but also for future buyers so they dont encounter problems.

I just went out and took it all apart again
I was curious if paint thhickness or something else was an issue, nope nothing found

It simply comes down to the bracket needs to be 30mm instead of 32mm

I just need sav and chuonthis to look at theirs and I'll contact ffc again as I'll have more evidence than just me alone. They were willing to look into things, but now they are not responding to me.

xtcnrice

^unfortunate.. I'm actually thinking of doing the RL BBK mod. I guess I'll hold back on the bracket for now as far as collecting parts is concerned.

chouonthis and sav don't have any noise-related issues though right?

Many people are using the FastBrakes bracket on a 1G TSX and have not reported an issue like this one. However, some people have been saying it's extremely difficult to put the caliper over the brembo-equipped 350z rotors because its thicker than the RL rotors. One person found it near impossible to put the pad in when the rotor was in, and another said they got grinding noises because the inside of the caliper was rubbing with the rotor (NOT the pistons... but rather a part of the caliper body itself).

paperboy42190 who owns a 3G TL (active member here) did a RL BBK conversion on his 3G TL using the FastBrakes bracket. He is using the 350z non-brembo rotors (2006+? I can't remember the year, but the base rotors increase in size after a certain year; basically the bigger non-brembo rotor of the two), because the brembo sized rotor wouldn't fit. So he has some pad overhang at the top, but he reported there are NO vibration/noise issues despite the overhang. He is using blank rotors iirc.

There is a lot of information out there, but it is very inconsistent. It's hard to figure out the true cause of each issue. Many others with the FastBrakes bracket have no issues using the brembo sized rotors. AFAIK, there is no CU2 using the FastBrakes bracket. Only the FFC. Perhaps you can buy the FastBrakes bracket and give that a try. It could even be due to your choice of pads and rotors.

I definitely have 2mm of the overhang
It could definitely be the drilled rotors
I'm going to check out the fastbrakes adapter and check the size

kostantinos

iTrader: (1)

I just called fastbrakes and this sh*t gets more complicated

He said you are suppose to use 12.6 maxima rotors and not not 12.8 350z track rotors.

He said he's not not even sure how I got the calipers on the rotor because it's not physically possible. I told him many have done it and he said the advics caliper can only handle a 28mm wide rotor and not a 30

xtcnrice

Yeah I have no idea. It seems to vary... some people fit the 12.8"x30mm rotors fine (seems like all the CU2s on azine cleared it), but a couple others had issues (like paperboy, and another 1G TSX on honda-tech). I can't see how using the FastBrakes bracket would no longer allow you to fit the rotor in the caliper though. If anything, maybe just shifted off center a bit and the rotor is misaligned with the opening of the caliper.

Do you think you're going to try their bracket? There are a few threads on tsx club and honda-tech about RL calipers and 1G TSX. It's just annoying as hell because the results are not consistent.

Also, CL9_Coop on tsx club is the only 1G I know of using the FFC bracket. However, FFC has 1G TSX and 2G TSX under different links. I wonder if the brackets are any different. Anyway, she had no problems running the FFC bracket on her 1G with 12.8" rotors.

When you Say the rotor is hitting the caliper and making grinding noises
, do you a pic of where. I'm wondering if that's what they m experiencing

xtcnrice

Installed RL brakes on my TSX with extras. - Honda-Tech

Post #19 for the pics. I read the whole thing. He downsized to the 12.6" rotor and it worked fine. But I don't know why this is the case for him and not for everyone.

edit: Post #24

kostantinos

iTrader: (1)

I checked that out but it doesn't look like mine. If the caliper
Touched, I would get noise right away, I get it under braking.
If I did 12.6, it would only make the overhang worse

Sav is going to get back to me this Sunday and hopefully I'll figure it all out

kostantinos

iTrader: (1)

I may be wrong but I think I may have figured it out. Just waiting for sav to get back to me

Sav says he has partsmaster 126206 rotors which he believes are 12.8

I think these are for the standard 350z which would be 12.6 according to eBay.
I can't find much more info on them. I'm waiting for him to measure them.

xtcnrice

Yeah 12.6" should be fine. Of course, I wanna run 12.8" if I can (which almost EVERYONE said you MUST use when they did the conversion btw), but 12.6" shouldn't be a deal breaker.

If you change to 12.6", you should probably get a new set of pads. The part of the pad that suffered from the overhang isn't going to line up exactly with the new rotors (i.e., the overhang portion on the 12.6" won't be the same portion you experienced on the 12.8"), so you may encounter even more issues. Of course, you could always just try it out first before you buy anymore stuff.

My mind cant stop with this; I'm researching, and researching.

Stoptech makes a 328x28 one piece rotor for their touring bbk for the tsx.
Would that work? at best it would need a tiny spacer behind the bracket.

What do you think?

kostantinos

iTrader: (1)

*edit* maybe it might not work because the 350z and tax rotors may not have the same center point?

xtcnrice

This I don't know. You could try asking in the 1G TSX tsx club and/or honda-tech RL caliper threads. You might find your answer there.

And yeah tell me about it... the research is like, you get in all this information, but it's all inconsistent so you don't know what to do lol.

Let's hope sav gets back to you. I can't seem to find any specs about the parts master 126206, other than they're meant for the 350z. It seems like on here, for example, they list every trim of the 350z. Parts Master 126206 Front Disc Brake Rotor | eBay

kostantinos

iTrader: (1)

We need a 350z expert to chime in
I think there 2 different sizes for non-track version depending on the year

xtcnrice

This is correct. The newer ones are 12.6". Older ones are even smaller and DEFINITELY won't fit.

kostantinos

iTrader: (1)

just got off the phone with partsmasters
the 126206 is 12.677 x 22mm

so i guess thats why it may work as it's thin, but i'm guessing more pad overhang as well.

robpp

iTrader: (2)

i used 2006 for the year 350z brembo when i bought mine from R1.

pretty sure it was not touring but more like race.

but cant remember exactly.

xtcnrice

Seems too thin. Might as well get the 12.6" x 28mm offered for 2006 base 350z. Haven't checked other years, but like you said at some point going older, the base 350z rotors are even smaller.

I put in 2006 350z base on NAPA, came up with these:
NAPA AUTO PARTS

I'm likely going to get these if I do this mod. I don't think it makes sense to try a set of brembo-sized rotors. There seems to be a good chance for things to not work out.

kostantinos

iTrader: (1)

I've been talking to stoptech and they make a rotor that may work,
120.44158 they have slotted/drilled/cryo/ blank etc

328 x 28 1 piece (12.91 x 1.102) made for the tsx (they use it on their touring bbk)

so it's plenty big, not too thin, and direct bolt on with no spacers needed.

xtcnrice

This sounds awesome, but also sounds pricey. One or two piece? From what I've read (and I haven't read much... so I'm probably way wrong), "better" rotors aren't worth it. You should be focusing on the pads.

But in terms of fitment, that rotor sounds like the perfect fit.

kostantinos

iTrader: (1)

one piece
it's about 50ish each for a blank and 100ish for a drilled

xtcnrice

Oh that isn't bad at all. I might look into that. You going that route? If so where are you buying these from? And is there a part number(s)?

kostantinos

iTrader: (1)

I guess i'll try, I have nothing to lose at this point

Great, let us know how it goes! I'd likely just get the el cheapo C-Tek blanks if I do this mod.

I just checked out the C-Tek blanks 121.44158:

Hub is 62mm. That's not going to fit for our cars (64.1mm).

I'm on it. Lol
He said they enlarge the hub opening for the tsx
I asked if they have a special part# or special order only

iTrader: (1)

**update**
still waiting to hear back from stoptech

***but here's a correction***
Whoever gave me the info on sav's rotors was wrong.
I asked 3 vendors on ebay and 2 said 324x30
and one of them said he measured 328x30, so if this is the case, that's why he has no issues

robpp

iTrader: (2)

50 posts ago I told you the ones I bought were 328.

kostantinos

iTrader: (1)

I hear you but savs are advertised as 12.8 but they are 12.9 in actuality and
Mine were advertised as 12.8 but we're a tad short.

xtcnrice

It's hard to say. There are two measurements. The full diameter of the rotors, and the "useable diameter". There may be miscommunication as to which diameter people are referring to when they're saying they're using 12.8" rotors.

xtcnrice

^^
I'm sorry, I done fucked up. That was completely wrong. I mixed this up with "new thickness" and "discard thickness"; nothing to do with diameters.

Anyway, as per here:
Installed RL brakes on my TSX with extras. - Honda-Tech

OP used these rotors (exact item):
http://www.napaonline.com/Catalog/Ca...250_0240009086

Specs:
Brake Rotor Diameter : 12.76"
Brake Rotor Discard Thickness : 1.12"
Brake Rotor Thickness New : 1.18"

xtcnrice

B_serious on that thread had issues with those specs though. Caliper was scraping the rotor simply on turns. His solution was to run 12.6"x28mm rotors, like these:
http://www.napaonline.com/Catalog/Ca...307_0480307688

I'm likely going to do that.

stoptech's response


"The kit that those rotors were assigned to have never been produced, only designed pending orders from the dealer that requested the parts for a private label kit. At this time, I would suggest offering the standard parts and having them modified by a machine shop in your area."

xtcnrice

geez.

Plan B kk?

kostantinos

iTrader: (1)

I have a friend who's a machinist
I'll see if he can do them for me

robpp

iTrader: (2)

so then just make the bracket a bit shorter at the machine shop?

iTrader: (1)

I can't keep the car apart because it's my daily and i dont want to put the oem brakes back on and bleed them

unless ffc is willing to send me new brackets, i'll try that
