Hello,

I have a 2005 G35 Sedan that I am trying to upgrade to a larger set of Brembo brakes that have come off a 2005 350Z. Every time I try to work on the upgrade, I run into issues. I am relatively young and haven't done enough research beforehand but I have started to do it every time I run into an issue. I plan on removing the wheel bearing assemblies to remove the dust shields for the Caliper fitment which is a long and painful task. I have the Calipers, Pads, Rotors, Brake Lines, and Brembo Master Cylinder and have just ordered spacers for all four corners. I have just noticed that the Brembo-compatible master cylinder doesn't line up with the mounting on the brake booster and am considering purchasing a different brake booster. I am posting this to see if anyone else has done this with a 2005 G35 and to see what else I could possibly be missing or some issues I could run into along the way. I am in no hurry as I will be going back to college soon and won't have the time and space to be able to do the change, but I might try to do it over a brake if possible. I just want to get this project finished so I can get onto some other mods that I have in mind in the future.

BTW: I am trying to make this a daily and a track car so my next mod is likely going to be a large suspension upgrade. So any info along those lines would be helpful as well. The Car already has some Koni Struts that were put on around 80k miles ago and need to be replaced soon. Power Mod wise I have a AFE Takeda Intake and a Borla CatBack Exhaust.

Thank you for any help you can provide.

 

Most people just trim the dust shields on the rear when doing the swap. I would wait to swap in the larger dust shields until you actually need to replace the rear wheel bearings because they have worn out (which will probably happen more quickly if you are using spacers...). You will also need the longer banjo bolts if you don't already have them, which can be ordered from Z1.

I did not swap out the master cylinder; stayed with the Infiniti OEM and added the Z1 master cylinder brace, so I can't help you with the Brembo master cylinder question.

 

How has the OEM Master Cylinder faired the Brembo one has a larger piston and I was wondering if that would have any impact on the amount of braking force.

 

Let's just say that when I was bedding in the pads that the last two runs had those babies smoking...like English pea soup fog...

 

Most who do the brembo swaps don't bother with the master. We just trim the shield and install the calipers/rotor/pads/lines and call it a day. I would do the brace as well if I still had the car.

Ive never tracked the G but heavy spirited highway driving and didn't run into any issues.

If you keep running into issues, I suggest going to pros. Don't think this as knock you on but brakes are something VERY important. You don't want to run into an issue while slamming on the pedal and the car not stopping.

 

Keep the existing MC, the Brembo one just has a larger volume for when the pads wear down, just check your brake fluid once per year and top it off and you'll be fine. It doesn't create more pressure or anything, just has a larger fluid volume in the reservoir because the calipers take more fluid to fill when the pads wear down.

You don't have to remove the dust shields, just hold up the caliper, mark where it hits the shield with a sharpie, then use two pairs of pliers to bend the dust shield lip up and back so it doesn't impact the calipers anymore. Or take a skinny wheel or a cutoff on a dremel and just cut/trim that section off if you want. You can do all this on the car.

Removing the front hubs isn't hard though, it's just four more bolts. Rears you will also need to pull the axles though but as long as you have some kind of 1/2" drive impact wrench (even harbor freight electrics work) and a torque wrench that goes to 250-275 ft/lbs you're good.
