Yes...yes, there are several threads out there covering this already for upgrading the single piston 90-91 front awd calipers to the 93-94 awd dual pistion calipers, and I have read them all. But I can't seem to find the answer for my question still.

The vfaq regarding this and big brake faq link that have been shared in all threads regarding this, all talk about a 'new hub mounting bracket' that needs to be installed for these larger calipers. Is this something that comes with the 93-93 brake caliper if I just stroll into an Autozone and pick up a set?

I guess I'm just trying to confirm if doing a 93-94 front big brake caliper/rotor upgrade is a direct bolt on swap as far as just throwing on the bigger calipers.

But I keep getting hung up on this whole 'hub mounting bracket'. -I understand that this will also require the larger 276mm rotors which I am aware of, and I also plan to upgrade the brake lines to ss while I'm in there.

The screenshot I attached from autozone says it comes with a mounting bracket, is this what everyone is talking about?

I just want to make sure I piece together all the parts I need and don't have anything missing once it comes time to installing these.

Thank you for confirming! I know it was probably a stupid question but there were so many threads were people kept talking about how critical it was to make sure to get the mounting brackets for them, and so I started overthinking it.
 
If you are talking about the upgrade from single piston caliper to dual piston caliper then yes, you need to order the calipers w/ brackets.

Oh wow thank you for that picture for reference from the single pistion and duel piston! Nice!

What do you guys recommend for easiest SS lines that would bolt right up to swap out the factory rubber lines?
 
I know the fitting style changed throughout the years. some are banjos, some are pipe fittings. Just make sure you know which the calipers you plan to use will have.

RRE can set you up with the lines regardless of which fitting type your calipers have, you just have to tell them what the hose ends need to be.

I have also ran Goodridge brake lines with no issues.
 
Many shops sell SS lines for DSM, so it would be your preference I think. But before ordering the lines, just make sure what fitting type your calipers have. The 1g is flare and 2g is banjo. Some manufacturers mix up and selling 2g dual piston calipers as for 1g or vice-versa. So even you order the calipers for 1g, you could possibly receive the 2g's.
 
I'm watching with interest, as I'm considering this same factory "mod" for my 90 gsx. Apparently the 92.5+ twin piston front caliper setup uses a slightly different proportioning valve (different pressure set points), but I've not read much about problems with mixing older prop valve and upgraded calipers/rotors. I've looked at sources like Rockauto, and they sell some brands of rebuilt twin-piston calipers with the mounting brackets, and some without. You would essentially pay the core charge permanently, since you wouldn't have replacement parts of the same type to ship back. Still not too bad, though, around $60 per side. Then rotors and pads, of course, with many options there. Hoses/lines are usually in need, as you are already looking. Certainly SS a popular option, though stock hoses are low-cost, and would be better than the old rubber ones on most cars (cracking always an obvious clue to condition). I think there end up being 8 separate hoses (inner and outer on each corner). Also note that 2g caliper/bracket/rotor fit just fine on the 1g, though reportedly a different fitting to attache the brake hose to the caliper (banjo, vs. flare). Might be easier to find some decent 2g parts. The calipers are different left to right, not sure about the brackets. The extra diameter and swept area on the twin-piston is an improvement, though I believe the much greater mass of the bigger rotor is a better sink for the heat generated and keeps temps lower for a given breaking event, which ultimately leads to better braking.

This seems straightforward, but don't they always?@#&!!
 
For you guys think on doing the single piston to dual piston upgrade you should look into to doing the Outlander upgrade. The Outlander share the same dual piston calipers with a different mounting bracket & even larger diameter rotors than the DSM rotors. Both options are basically bolt-on upgrades.
 
I JUST did this......

It bolts right up and I used 1995 hoses. I covered it pretty good in my build thread update as of just a month ago or so.

What year of Outlander @Mello ?
 
I like the idea, but concerned about wheel clearance. I’m fond of my 16” turbine-style rims, and have read of no problems with the 92.5 upgrade. I noticed in those photos that there were stock 2g wheels, perhaps they are better for this?
What about prop valve?
 
The stock rims clear fine, although they get closer. I run the 2g rims just because I like them but these brakes are also on my Red Talon with stock rims for her so I know they clear 1g rims also, 16". I left my prop valve alone and the brakes work great, got me slowed down from my 3 blasts down the 1/4 mile track last week at over 117mph with no effort.
 
The dual piston upgrade is a great DD/WW brake upgrade, the outlander is the next step towards a weekend warrior/street strip setup and offers the same level of install ease. Many suggest also upgrading the MC to a 3g unit for better pedal feel, but the prop valve does not need to be changed unless you want absolute full control over the brake bias. I personally have outlander front brakes, RRE lines and a 3g MC and booster combo, and my brakes are excellent with no wierd tendencies.
16" wheels will clear the outlander brakes, but it's very iffy on which ones will. I can tell you stock 2g swirlys will clear, barely.
Otherwise the dual piston upgrade is a logical step for many people considering cost is so low for the performance.
Next step for easy upgrades would be a set of early 95 rear vented brakes for that slight edge and factory for upgrade. GL!
 
I need to go steal my sons 95 rear vented rotors off of his Talon.......:shhh: :cool:
 
Yes I thought that it was a nice "kit". Buy the #KC798A26 kit and just pay the core for the old calipers.
You will need the 1995 hoses as they are banjo bolt fittings, but I got those from RockAuto for under 15/pair, so you need the PowerStop kit, 2 front hoses (and look at my write up on how to fit them) and 2 banjo bolts (also from my write-up) and it bolts right on, looks good and performs wonderfully! :thumb:
