Infiniti G35 Brakes and Rotors



  • akdlakdl Posts: 1
    Hey guys. Any luck on finding a nice set of cheap rotors? I'm in the same situation as you guys. I have an 03 coupe with brembos. I resurfaced them about 15000 mi ago and had my dad change the pads. I made it to 45000 with the stock rotors on. My dad is going today to see if they can be resurfaced anymore when they rotate my tires. I looked online and they said they can be resurfaced only up to 8mm front and 6mm back. I'm looking at my rotors now and I'm wondering what kind of rotors they are. They look like they have a lot more meat on them. They arent the cross-drilled slotted kind that I see everywhere when looking for rotors for my 03 coupe. Now I'm dumbfounded as hell? I'm curious as to whether this is the stock rotor, or an aftermarket rotor. I bought the car at 25000 mi. They have the brembo calipers but look like different rotors? If you guys find anythning cheaper than the $370 replacements let me know.

    My brother has an 04 coupe with brembos sport package as well, I believe he has the same rotors, I have to look when he gets back :)
  • Hey here. I have an 03 sedan and have had it from the start. The warranty has run out and I don't want to pay the $2500 the dealership has quoted to change out the rotors and pads. I am mechanically inclined to an extent. Is this a job I can do on my own? Do I head to a discount auto parts or should I head a specialty shop? I am excited about working on the car, but want to make sure its done right. Any thoughts?

    I have gotten great wear on my brakes and they stop quickly (although I do get a lot of brake dust), but due to the known problem the dealership replaced my front brake pads and rotors when my car was in the body shop last year under warranty. Now I need to replace the rear brakes (I have 80K miles on them or at least 45K that I put on them). I don't want to pay the dealership to replace them so my dad is going to do it for me, but I am having trouble finding the parts. First I was told they couldn't get the pads if I had VDC (Vehicle Dynamic Control) which I do, and thought everyone had. Now I need to know if my car has Brembo calipers because I've been told they require different pads. I have an '03 RWD G35 Sedan. Does anyone know how I can tell if I have Brembo calipers and does anyone have a good website to order the pads and rotors from? Thanks!
  • :sick: I have a 2004 G35X. I am trying to change the rotors and brake pads. I can remove the caliper but there are 2 19mm bolts that I can't seem to loosen. Hell maybe I don't even need to remove them but I don't see how I could remove the rotor if I don't remove the 2 bolts. Can anyone help???
  • After you loosen and remove the 2 14mm caliper bolts and remove the calipers(hang them off the suspension with a bungee cord) and remove the shoes by sliding them off their tracks you must remove the 2 - 22mm bolts ONLY if you are changing the rotors or getting them machined. They are on really tight so use a long handle good quality ratchet and a lot of muscle. After they come off(2 bolts per side) you can now slide your rotor off. Reverse the steps to put it back together. Don't forget you will have to slowly retract the caliper piston with a C clamp to make enough room for the increased thickness of the new pads and rotor. Hope that helped. I just finished mine and it took about an hour and a half excluding the time to get the rotors machined.

    i just replaced our front rotors on 2005 g35x after 50k miles! only had to remove 4 caliper bolts total, and the 2 14 mm are on tight. Rotor is just stuck to hub and had to be banged off. there are no screws bolting rotor to car. I have no clue what the guy above is refering to. there are no 22 mm bolts around the rotor. Rotor is just hugged in place by pads once everything is on, then by wheels and lug nuts. hope this helps
  • Yassy, with all due respect, 2004 G35X Sedans sold in Canada have 2 14mm bolt pins holding on the brake pads and 2 22mm bolts securing the caliper body to the car. Do you perhaps have an upgraded Brembo brake pkg. on your car?

    I have done this dozens of times. The standard calipers in the premium G35X pkg is 14's and 22's............

    no problem. you are right. only 4 bolts hold caliper together that need to be removed. there is no screw holding the rotor onto hub. Actually the 2 bolts that were difficult to remove were 18 mm. The other bolts are standard 10 mm bolts holding piston onto caliper on our g35x. dont know why infiniti would put diffirent size on yours, unless you have different brakes. on the x i believe the front brakes are smaller.
  • Its odd that they have different bolt sizes for same model year. The last one I did was a late model 04 so perhaps it was already getting 05 calipers when it was built. Anyway they make for an easy pad replacement and a fairly easy rotor remonal if necessary.
  • I just had a front wheel bearing replaced on my 2005 g35x. Under warranty, but makes me wonder about quality. However, they discovered a transmission leak and now I need a new radiator. The warranty ran out at 90,000 kms. I'm at 94,000 kms. And front rotors needed ... again. Is this a piece of junk, or what? My son has an 11 year old Honda Accord, and he's never had these kinds of issues. Any thoughts or suggestions are welcome. I'm in Canada.

    the early G35s and FXs were notoriously bad when it came to rotors and brake pads: actually, in the beginning of 2003 or 2004 it wasn't covered under warranty and Infiniti was sued and forced to cover rotors and brakes under warranty because of the amount of people having problems with them and complaining: I had a 2005 FX35 that needed the rotors resurfaced and brake pads replaced every 10k miles while I leased it: luckily it was all covered under warranty but suffice it to say I didn't keep the FX because of these issues because they would have added up to alot of money year after year once the warranty expired: each time the car was done the bill was $300-400 bucks a pop: I was in the dealership over the years many times with people with 03-07 G35s having the same issues that I did with brakes and rotors every 10-15k miles: its a shame because except for the brake/rotor issues, my FX35 was absolutely excellent and problem free for the 42 months I had it!!! best of luck on your decision!!

    I bought my 2006 G35 6MT Sedan new in Feb 06. I have 45,000 miles on it now. Just replaced the tires a couple of thousand miles ago, and checked the brake pads while the wheels were off. Front pads still looked ok w/ plenty of pad thickness, but the rear pads were getting a little thin. (I was a little surprised that the rear pads wore faster then the fronts). Anyway, I have been very happy with the performance of the original brakes. The car stops great, no noise/squeals, no "shimmy". There is some noticable brake dust and perhaps other pads could have lasted longer, but like with tires, I'm ok with sacrificing shorter life for better performance. I don't do any track/racing, but I do drive my car pretty hard.

    So, I am now looking to purchase new pads (I'm comfortable doing the install myself), and am looking for some recommendations for some relatively affordable, good performance brake pads. Anyone have any good experiences?

    Thanks, and happy holidays.

    Nothing at all wrong with 45,000+ miles on a set of brake pads.

    Were those the OEM tires that you just replaced???
  • I brought my car in for servicing today only for an oil change and ended up needing new rear brakes at 20,000 miles. Dealer said the pads are real soft and wearing out between 18,000 and 22,000 miles. Is anyone else having this problem? BTW I had no signs like noise either.
  • srs_49srs_49 Posts: 1,394
    20,000 mile sounds a bit early for rear brakes. Maybe the dealer thought he doing you a favor by replacing the pads before you started to hear anything from the wear indicators.

    How much did they charge for the rear pads?

    Were the front ones replaced earlier, or are they still OK?
  • No problem with front brakes. Around $370..rotors also resurfaced.
  • I have a 2007 G35x with 24k and I started to notice a faint squeal (thought it was because of cold winter temps outside) about a month ago. I brought the car in for oil change and dealer told me that I rear pads where at their minimums and I should replace them at next oil change. They quoted me about $350 with parts and labor.
  • Looking to replace my brake pads and am currently looking at 3 options. Any thoughts, opinions, better ideas. Looking for minimal noise, increased rotor life, low dust... use for everyday driving.
    1. Hawk HPS: High Performance street
    2. Hawk PC: Performance Ceramic
    3. Project U NS Street Pads

    I don't have personal experience with any of the pads you mentioned. Most people seem to be happy with Hawk products. The HPS's will probably produce a bit more dust but be easier on your rotors than the PC's.

    I love this car and have had no problems with it but for the brakes. On reading the posts I can see premature brake wear has been a problem with earlier years of this model, but I don't see anything like the problem I'm having with my 2008 G35X. Front rotors were turned under warranty at 11,231 miles. All rotors turned and pads replaced at 27,936 miles due to only one of the 8 pads being worn out! I paid the full bill because dealer said this was "normal" for a sport sedan. After significant discussion about how only one pad could get worn out, I got 50% of the bill covered and accepted the rest as "betterment". Now less than a year later at 50,842 miles I've got symptoms of warped rotors and I'm told I need to do the pads again because another single pad is down to the safety-fail limit. So my question is, has anyone else been successful getting Infiniti to acknowledge they have a problem with the braking system or parts quality that causes individual pads to wear faster than others? I'm a very consistent driver and almost all the miles are highway use, so there is no excuse for $800 to $1500 bills every year.
