Would the D721 platform swap over and down to the D722 braket and caliper wise. Trying to put 2 pots on the front of a 99 gf8. Wheels are 16x6.5 55offset. Also rotor size would be a given right?

Quick double check.... i have an 05 wrx stock brake set up currently... picking up the 4/2 pots... do i need the rear hub as well off an 06-07? do i need the rear bracket to have em fit? am i wrong to believe the fronts mount up fine with bigger rotars?

Fronts mount with the same rotor, rear calipers need an adapter to fit a larger rotor size.

Our v1 bracket will work with Brembo or 2 pot rear calipers.

I assume the hubs are the same for 02-07 and the bracket is the thing that changed but you'd have to verify that. If the hubs are basically free grab em, maybe you can resell em and recoup some costs.

The rear calipers on the pre-2008 mount to the backing plate. The backing plate bolts to the upright and holds the parking brake stuff and caliper and the dust shield is on there too
The 02-05 WRX and 06-07 wrx have the same upright and hub, but different backing plates. You can swap them, but you have to press the hub off and take apart all the parking brake stuff to do it (and buy new wheel bearings). If you had just had a complete set of 06-07 wrx uprights then yes you could put those in. |

The rear calipers will not. The mounting is different and there is no bracket to adapt the new caliper to the old car. However, you could put the 07 calipers on the 16 with KNS's V2 adapter brackets. You would not want to though because the gold caliper has smaller pistons, at I think 36mm instead of 40 so it will effect the bias and how your brakes feel. |

The rear backing-plates are the same 2002 to 2005 and were changed 2006 to 2007 to accommodate the 2-pot calipers. Installing an adapter to a 2002 to 2005 to install a 2-pot caliper is much, much easier than removing the knuckle assembly, pressing out the hub, and then removing the backing-plate and then the reverse order to reinstall. |

on 2018 WRX i need to downsize front brakes to fit 15" gravel rim.
any chance You know if there are rotors with 5x114 bolt pattern to combine with 06-07 WRX calipers? ...just don't want to re-drill 06-07 rotors thanks Quote:

Yeah those will work, and actually, you can't re-drill the 06-07 rotors because they won't fit over the larger 5x114 hub.
Stock rear brakes will the rally wheels fine and there's also a bracket to use 2-pots. KNS makes that too. |

power stop
so I have a 97 lgt, was looking to grab a power stop kit for it but they only make the front. so... here I am
can anyone help me through all this info... I don't want to lose my parking brake by upgrading to the wrong wrx or leg setup |

I don't know what a power stop kit is, but I have WRX front brakes and Legacy "H6" rear brakes on my LGT. No change in bias, no issues with parking brake, and same caliper pistons sizes but bigger rotors all around. Fits under the stock wheels and works really well as an upgrade.
To do that you need front caliper brackets from a 02 wrx and calipers and brackets from an 00-04 legacy or 99-07 impreza. Then the appropriate pads and rotors. |

SO it talked about rotors. but what about calipers. my question is what Calipers would give more bite and stopping force on my 2012 impreza 2.0 I. what calipers do I have ? a 2/1 set up. would steel lines, and some good amsol dot 4 fluid help. I autocross and right now the front wants to slightly dive, pedal is squishy, and I get some vibrations if i stay in a high gear and left foot brake ? what does the vibrations mean caliper sticking or warped rotors ?

to get an unbias/technical breakdown of brake setup, i'd start here:
one of the key take away items: brake pads are more important than the number of pistons within the calipers. brake balance is barely thought of by most people. most people get as aggressive/powerful front brakes with virtually no thought to the rear brakes. the setup i've gone with is: EBC Yellow front pads Hawk DTC-30 rear pads the DTC-30 are super aggressive. the Yellows are NOT as aggressive. this causes a slightly more rearward balance. i get less nose dive than a 'stock' setup or a 'same pads front and rear' setup. AMSOil makes a good brake fluid, but i run the Wilwood EXP600 fluid as it has better wet/dry boiling temps. |

First off, apologies for the massive quote from the first post... I did some trimming and also highlighted in red and hot pink some of the pertinent info on calipers. Original content referencing it is below the quotes.

I've been studying this thread for a week or more and it has sent me off in all sorts of awesome brake learning tangents. I'm glad to see the thread has turned towards calipers, because that is what I want to talk about. I think that a post that directly identifies and compares the different Subaru calipers would be helpful. This isn't that post, but maybe it's a start towards such a goal. Anyway, here is my experience. At the end of 2010 I picked up a bone-stock 1998 Legacy GT Wagon that needed work, including brakes. I was new to Subaru but learned enough from forums like this one that I decided to do the WRX Front / H6 Rear brake upgrade as soon as I got the engine running again. The car had been sitting for a couple years and had a seized front caliper. Since I needed to change from '95-'99 Legacy rear calipers (the older 1-bolt/1-slider asymmetrical style that will not fit on H6 Brackets), it seemed to make sense at the time to replace all four corners with newly-purchased remanufactured calipers to go along with the nice new EBC performance rotors and stainless brake lines: http://legacygt.com/forums/showthrea...-154702p5.html During installation I discovered that the '00-'04 H6 rear caliper has a notch for the hard part of the brake line fitting that does not line up with the '95-'99 Legacy brake line orientation. I bolted the line to the caliper but by bypassing the notch, it has always been in the back of my mind that the line could potentially work itself loose over time. Once completed, the braking performance was plenty good enough for a daily driver, but shortly after I got the car back on the road I came across some information that made me doubt the reliability of cheap remanufactured calipers. Here is a video covering the issues with remans... Disclaimer: it is a sales video posted by a Seattle-area repair shop but I have no affiliation with their establishment: I also foolishly assumed that the grey "paint" that came on the remanufactured calipers would keep them looking nice for years to come, but in actuality I should have painted them myself because the cheap coating appeared rusty within a few weeks. As far as the reliability of the remanufactured calipers has been... well, a couple years after the car had been back on the road, one of the rear calipers seized, but I was able to change it out easily enough with a warranty replacement. So far the other calipers have held up okay, but another minor issue that I have with the reman calipers is that I can hear what sounds like the pads dragging ever-so-slightly on the rotors with no brake applied while traveling with the windows down. This is most likely due to the inability of the caliper to fully retract, which if I understand correctly is contributed to by flimsy aftermarket rubber boots over the slide pins. In any event, this has surely contributed to increased pad wear and that brings me up to today, as it is time to redo my brakes. Using what I've learned from personal experience, and what I've learned from brake reference threads like this one, I have decided that I want to replace most of my braking components. I want to stick with the WRX Front 2-piston sliding caliper / H6 Rear 1-piston sliding caliper setup, but I want to remove the remanned calipers and return to factory OEM calipers that have never been to a mass remanufacturing facility. I want to disassemble, clean, paint, and rebuild them myself with Genuine Subaru seals. Big Brake Kits, Brembo, and Fuji Heavy Industries 4-pot/2-pot setups are out of the question due to expense and because of my winter wheels that won't clear (stock Subaru 16x6.5 Snowflakes). Front WRX calipers changed mid 2003, and from my research it appears that the Legacy GT and Outback also got this revised caliper. It is my understanding that the newer design remained in use for many years and has a larger selection of pads to choose from. 2005-2009 Legacy GT with 11.4" / 290x18mm vented rear rotors setup was an option I was investigating but is undoubtedly overkill for my application. I believe this rear setup might clear my stock 16x6.5 Snowflakes, but probably not my stock space-saver spare tire. I do want to change the type of rear caliper from Legacy-style to Impreza-style on the H6 bracket in order to properly route my brake lines and get my peace of mind back that the fittings won't work loose over time. I've had to study to understand which models/years would have the correct rear caliper that solves this issue. I was sidetracked by discussion of a change of rear WRX caliper and pad type between Model Year 2003 and 2004. One of Jamal's quotes above explains that the caliper bracket and thus pad type did indeed change for mid-'03+, but that the caliper main housing itself did not. Thus the options are more common and more recent that I thought at first. The past week I've rounded up a boatload of used OEM 2-pot/1-pot calipers to compare. I've got older 2-pots from an '01 Outback, which use pad style D721 and are the same as '02 WRX. This is the same style as the remans on my car now. I also picked up revised 2-pots from an '07 Impreza Wagon, which use pad style D929 and are the same 2-pot sliders as mid-'03 WRX, but their original brackets won't clear 11.4" / 294mm rotors. So I separately picked up a pair of '07 Forester caliper brackets, which I believe also used the same 2-pot sliders and 11.4" rotors as mid-'03+ WRX. For the rears I got a pair of '01 Outback rear calipers (with the brake line notch in the wrong orientation) and their H6 brackets. The '07 Impreza rear calipers will have the proper brake line notch, and will be paired with the Outback brackets. All the parts that I will be reusing I'll disassemble, soda blast, paint, and reassemble with genuine Subaru rebuild kits before installing. |

Well, silly me.
I thought I had done my research. I assumed there were "pre-2003" dual-piston front calipers, and "post-2003" dual piston front calipers... same size pistons, just a different shape housing, bracket, and pad. It seemed to me that the 03+ caliper was the way to go... I figured I'd make my car essentially have the exact same brake setup as a 2004 Legacy GT. I found someone locally parting out a 2007 Impreza Wagon. Perfect! Right? So I bought all four calipers for $100, to clean, paint and rebuild with all new seals. I've had the calipers for a week, and I finally realized that these pistons are not 1.685"/42.8mm. They are obviously larger (Pre-2003 caliper with Outback bracket on left, Post-2007 Impreza caliper on right): Not sure what to make of this as I kept reading that "You can put any Subaru brakes on any other Subaru". I was not expecting a change in piston size and I think this has something to do with a change beginning with Model Year 2007 Subaru vehicles. I don't think this particular caliper swap is a good idea because the change in piston size will almost certainly change my brake bias in an undesirable fashion. The rear caliper pistons appear to be the same size as earlier versions. |
