use 4th gen rotors and 5th gen calipers/pads on the rear.

What about the front of a 2009 v8? 4th gen rotors or 5th?

can i use 5th gen calipers on the front with 4th gen rotors? after "inspecting" my calipers visually they looked ok so i bought brembo 4th gen rotors for the front but during disassembly just now i found out my calipers are no good. if not ill just grab some 4th gen calipers

Has anyone experienced issues with just doing the 5th gen upgrade up front, leaving the rear 4th gen calipers?

Issues like what? I have seen/read that people who only do the front ones, suggest to do the rears as well. I guess if you are going to jump in the pool, may as well go in head first.

Soft brake pedal? Although those issues seem to be bleed procedure related.

My rear brakes are fine- have a steering shake/pulsation up front that I'm fairly sure is caliper related.

No issues here.
I have 4th gen rotors and calipers in the rear and 5th gen calipers and rotors in the front. I also switched all 6 brake lines to stainless steel.

Perfect- thank you.

Had the extra time this weekend to do the swap. Painted the calipers with G2 and added some stickers. I'm VERY happy with how they turned out. I used Carquest Platinum Painted rotors and Wearever Platinum Professional Ceramic pads all around. After all the discounts and rebates, I got all the rotors and pads for ~$200. I bought the calipers from Rock Auto. All in all, after core charges are refunded, discounts and so on, I'm ~$430 for this project, including the G2 paint and stickers.

I had some vibrations in my steering wheel and floorboard when slowing down from highway speeds. None of the OEM calipers showed signs of seizing, however the rear pads were worn down. I'm pretty sure they were the original OEM pads. After the swap, it brakes great! No vibrations at all!

out with the old:

How much are you guys having to bend the brake shield for the front rotor to fit?

I have my truck at a shop who won't do the work as they won't bend the brake shield as much as it needs to be (at all?)... they say the rotor won't move at all when rotor is on the hub.

Pictures of bent shields anyone can share?

I didnt have to bend mine much at all.

Did you need to bend only on the outer edge of the shield, or toward the hub as well?

Verified the part number appears to be correct- this look like the correct rotor offset?

Shop is telling me the rotor was hitting the caliper itself, not the shield. Not sure I believe them at this point.

I just did mine last weekend and there were 2-3 areas, mainly very top and very bottom, where I had to bend it ~1/4". Maybe they need to push the rotors onto the lugs more to get it to stop hitting the caliper?

Those will work as long as the right ones are in the box. Get a different shop.

Unfortunately no stampings on the rotor. I'll have it to another shop next week. Worst case I have them get a set of 5th gen rotors from Napa.

Calipers have the correct 14WA stamping on them.
