Hey Gwoods - you were asking about brakes...

[rn79870]

I couldn't find the thread with your question about brake pads. I ran across this while looking for something else today.

http://www.car-stuff.com/carpa....html

That picture makes it look like one of those foam sanding pads lol.

Good find RN.

[gwoods]

Thanks man I'm on the phone with them now

[gwoods]

Okay I bought them.

Should be here in a 4-7 days...

Now find me a set a drilled and sloted rotors!

[fatire_mtb]

check out http://www.r1concepts.com

remember to follow the bed in procedure

[rn79870]

If fatire's suggestion ^ doesn't work out, these might. (from the same source as the pads..)

EBC SPORT SLOTTED AND DIMPLED BRAKE DISC SET -- Made From Premium Quality Castings, CNC Precision Machined To Enhance Overall Brake Performance And Appearance, Designed To Draw Cool Air To Reduce Brake Temperatures Whilst Removing Dirt, Dust, And Debris, Engineered To Improve Braking Performance During Wet And Dry Conditions, Set Includes Left And Right Drilled And Slotted Sport Rotors, Black, Features A Dimpled Hole Construction To Prevent Cracking And A Black Zinc Coating To Prevent Corrosion, 12.6 Inch Diameter

$262.13

(anybody who says "whilst" scares me.)The list shows a 07 G35, but it calls it a VQ35DE. I'm wondering if that matters.

I'd recommend with going with just slotted rotors....crossdrilled ones usually end up getting stress cracks around holes and you have to have the rotors replaced more often w/o ever ever getting to resurface them. Check out the MB's with the AMG brakes, they have these spider cracks on them all the time.

[gwoods]

Those rotors are for the 07 Coupe which shares parts with the 06 Sedan... The 07 Sedan and the 08 G37 share parts.

No luck on anything other then factory rotors which is fine because my can be turned once.

I'll post some pics when I get them.

R1 Concepts has nothing for 07 sedans... just like everyone else.

I finally found rotors for my car! $251.78 shipped for drilled and slotted with zinc plating. http://www.ocautosports.com/

"These rotors are guaranteed to fit your vehicle. Our rotors also include a ONE YEAR WARRANTY against warping or cracking. If you are interested, please call us to pay with a credit card over the phone. If you have a paypal account, please send payments to [email protected]. For money order, please mail all payments to OC Autosports, 2221 E. Winston Rd. Suite P, Anaheim, CA 92806. If you have any further questions or concerns, please feel free to contact us at (714) 817-0000 during our normal business hours of 9-6pm PST. "

This company cuts their own rotors so it takes time.. I ordered today so my rotor set will be cut on Monday. Then they will be drilled and zinc plated will ship by Thursday at the latest.

This should be quite a bit better then stock. I am slightly worried about cracking them since they are drilled but the drilled holes are spaced further apart then most drilled rotors and chamfered to help with stress.The salesman said if they crack within 1 year of the ship date I can have new ones sent out for free!

I'll post pictures... now if my factory brakes can just last one more week!

Jeff

[Sentientbydesign]

Are you going to beat on them for the first 11 months? lol

Glad to know you found some. I'll keep them in mind if the Powerslots are too expensive.

[gwoods]

That car-stuff.com sight just sent me an email canceling my order... I placed the order over the phone on Wednesday? I hate it when companies can't keep track of their stock and will never order from them again.

I am trying to get pads from the place I bought the rotors from.

Jeff

Sorry I directed you to them. Maybe someone should direct them to this thread and the negative publicity they are receiving because they can't deliver. I'll google the pad and see what else I find when I get a minute.

[rn79870]

Jeff, give Summit a call, Google hit them as a supplier of Redstuff Ceramic Pads.1-800-230-3030

[gwoods]

Summit says back order until 3/3/8!

I'm driving on borrowed time with the rear brakes right now...

I am going to ask the company I bought rotors from to sell me pads too.

[gwoods]

The company that is making my rotors is also shipping me ceramic pads for $88.

I also found a the missing front rotors on http://www.autopartswarehouse.com for my car so I ordered them too.

I'll end up with a set of EBC redstuff pads, another set of ceramic pads, my stock rotors which I will have turned and the OCmotorsports drilled and slotted rotors.

That should be enough brakes for this year.

I'll probably order another set of rotors next year when I turn the drilled/slotted

I am so tempted to do drop spindles all around and a strut tower brace up front..... but I know if I start I won't be able to stop so I'll just dream about it LOL

One more thing you may wish to look into is brake fluid improvements. There was a lot of hoopla about silicone brake fluid (racing brake fluid) some years back. I don't know if this is compatible with Infiniti or not, but it is suppose to be heat resistant and provide a better feel. With your other improvements, it may help the brake feel. (I don't know that the QM really matters, but if you get back out on the track, it might)

Maybe some Infiniti tech can shed some light on whether silicone fluid is available for the G or not.

Silicon based brake fluid can be used on practically any car. But you have to be able to get rid of all the glycol based fluid already in the system. ALL OF IT. The two will not mix at all.

Even if you did, expect the pedal to feel somewhat spongy. Silicone based fluid is slightly compressible.

A simple suggestion would be to upgrade to DOT 4 fluid (I've used the Valvoline DOT 4 on a number of track events) and call it a day. DOT 4 is still very affordable as well. Chances are, you'll likely experience heavy pad fade before your brake fluid begins to boil. If you haven't experienced pad fade and don't intend to drive in a harsher environment (i.e. road race course), then you're DOT 3 fluid will likely be sufficient. Frankly, most people would be better off flushing their fluid often rather than upgrading.

To clarify, pad fade occurs when the pad temperature increases to a point where the binding resins begin to vaporize, forming a nice layer ov vapor btween the pad and the brake rotor. The effect is similar to your tires hydroplaning on water. Fluid fade occurs when brake fluid actually boils which introduces air into the brake lines. The difference is easy to detect. With pad fade, the pedal will remain firm and feel normal, only, the car won't be slowing down as quickly for a given amount of pedal pressure. With fluid fade, the pedal will actually sink further to the floor for a given amount of deceleration. Pad fade almost always occurs first.

As I said, a good DOT4 will be a reasonably priced and easy upgrade. There are DOT 5 glycol based fluids, but for most people, they are overkill and pricey. Like any other glycol based fluid, it absorbs water and the boiling point will be reduced to a point where it should be changed. As such, unless your driving conditions requires it, there's no reason to waste your money.

Thanks C-Kwik, I also heard that changing to braided steel brake lines helps do away with brake sponginess. Again overkill for a street car, but if someone ran at the track frequently, do you think it would be worth it?

[gwoods]

Brake fluid change and the engine decarbonizer is schedule for my 30k mile service in Mayish. I had IOS change the power steering fluid with the last oil change.

I had IOS service the transmission at 20k miles will do that again at 40k miles.

Probably service the diff at 35k miles

At 40k miles I will change the spark plugs myself, using OEM plugs at OEM gaps.

I have never felt brake fade in the G even working it out hard at the track. The front rotors hot spotted so I have a little vibration under hard braking but otherwise the brakes were great just worn out quickly!

I think the drilled/slotted rotors and ceramic/kelvar pads will solve my hot spotting problem. If they last a year I'll be happy.

I've been kicking around the thought of running dryer duct from the lower grill opening to the wheel well to help cool the front brakes but I'm concerned with how it would look.

Depends. Newer lines will swell very little under pressure, but as it ages, it can start to make for a spongy feel. I'd say steel braided lines are a great upgrade as they should last longer and perform more consistently than a rubber brake line. But with a newer car, it might not be the first thing i rush out to upgrade...

Here is some info that may pertain to yout hot-spotting. I'd explain it, but they do a real nice job of it and it saves me the typing:

http://www.stoptech.com/tech_i...shtml

As for a brake duct solution, consider the info in the link I provided first. Understanding how the problem occurs can make the solution obvious.

If you must run brake ducts, then you might consider some intake ducting from the auto parts store. It's made a little more robustly with thicker 'skin' which holds up better to the conditions it woud see. Be aware that there is also a automotive heater ducting that looks similar which is relatively thin skinned. The ones i used in the past were black so it should hide pretty well too.

[gwoods]

Thanks man,

I am the second owner of my G so I don't know how the brakes were broke in. I bought EBC pads and am planning on following thier break in process for the pads. The pads are 'red stuff' and designed for high performance street with some track use. The next step up is 'yellow stuff' pads that are for track use only cause they don't work cold. A set of red stuff pads for the G is about $180! Just plain ceramic pads are $88 shipped. I bought both, I'll try the red stuff pads first.

Then next auto cross event is May 10th so that will be a good indicator of whether I need ducting to help keep the brakes cool or if drilled/slotted rotors are enough.

I'll have my turned stock rotors and another set of ceramic pads I can swap in at the first sign of pedal pulse. Driving on the street normally even with 15% rear pad and front hot spotted rotors the brake system performs great and without any noise or pulse. Make a couple stops from 100+ and I bet that would change.

At the last track event I did 25+ stops from 120 + mph down to 50-60 mph. At the track I am a late braker but not late enough to kick on ABS, basically when I feel like I should be hitting the brakes for the next turn I wait a second and then mash the pedal hard once and twist the wheel as I'm letting up . I think the stock brakes did great considering what I put them through!

All my parts should be here next week sometime so look forward to pictures and hopefully no busted knuckles!

How are the Rotors holding up???I'm plannin on upgrading my brakes soon and wanted to see how these have been working for you Jeff.

You paid $250 for the fronts or the rears?

[gwoods]

$251 shipped for front and rear rotors.

EBC redstuff pads are $60 for the rear and $90 for the front.

OC Autosports sold me front and rear ceramic pad for $90.

I'm running redstuff pads on the rear and OC Autosports pads on the front. I was never able to get a set of front EBC redstuff pads I ordered them from 3 different sellers but got a sorry email and a refund a couple days later. Even ordered over the phone on the first set to avoid this problem.

They are holding up great still stop quick, no squeak ect.

Next Sunday I'll be at the track racing hard. That will be the test. I'll probably take the car apart next Monday and inspect the wear.

[tollboothwilley]

I bought some of these rotors today from OC Autosports

They were something like $135 + shipping for the rotors alone.

They are made from high quality G4000/G5000 iron with the zinc coating to prevent rusting on the hub.

They also have come out with a new unique design where the slots are channeled all the way to the edge for more even pad wear.

I'll also give my feedback when I'm done with the swap.

I think i'm going to be putting SS braided brake lines on with new/better brake fluid.
