running 99+ stang twin pistons calipers on 95 spindles

is there any modification i need to make to put the twin piston 99+ mustang calipers on the 94/95 spindles i have on currently?
i just can see this as being a direct swap..

You will need to do a little grinding on the spindle ears to get things to mate up properly, but it is a bolt-on deal.  Once you have the pieces in front of you, it will make sense.  The ears on the 94-95 are a little more rough and chunky than the later ones.  Other than that, it's a no-brainer.  I ran some of those on my 84 XR-7 and the 80 Z7.

ok sweet..
i grabbed them out of the junkyard a few months back but been hesitant on mounting them, since is salt season the car is sitting.
maybe ill attempt the vacuum booster swap too!
thanks
i have a feeling this was covered before but couldn't find the result when searching "twin piston caliper"

another note.
would installing 99 up spindles be better?
the car is lowered an inch and i notice the tie rods are angled up a bit when on the ground.... but no bump steer

No.  96-04 spindles would actually be worse.  Unless you're swapping a 4.6 K-member, or deciding to spend the money for a bump-steer kit from one of the aftermarket suppliers, there is no need or gain in the 96-04 spindles on a Fox car.

Stay with the 94-95 spindles.

its been a little over a year and finally today i went to install my twin piston calipers.


like chuck said once i looked it over i would see where i had to grind. wasnt a lot to remove and it went very well to install.






even tho the installation went very well and simple.
i had other issues. leaving the calipers in a box in a shed that was subjected to moisture the pistons and calipers corroded and seized once i apply pedal pressure.. so im going to rebuild them.
only one piston "popped" out when i went to disassemble them. going to talk to my ole wise father and see if soaking them in brake fliud would help to get them apart.
at this point i may just wait and buy cobra calipers and rotors and go 13in. we will see... ill post again once i see if i can get the calipers apart

so i just reinstalled my single piston ones and was back on the road...

Are remanned '99+ calipers out of the budget? I know they aren't "too" cheap, but if for nothing else than peace of mind, I'd rather spend the money than trust salvage yard pieces, Brian. ;)

I bought a set of 03 Mach 1 Spindles for dirt cheap because the car was totaled, and they only have 12k miles on them. I will be doing this same kind of swap, are the Mach 1 spindles gonna give me any trouble or is it just the bump steer kit that I will be spending extra money on?

BJL,
You can get the calipers only (no bracket but you already have that) for about $40 each at any parts store but you will need your green gremlins for the core charge.  I would not even try to rebuild these as I just don't do cheap on brakes and I don't trust me and a brake hone.

cougrrr302,
Do not use the 96+ spindles on a stock K-member car.  Read here: http://www.maximummotorsports.com/store/index.php?main_page=tech_front_susp_spindle_warning

i got my wedding in 6months and that taking alot of my $$$. to be honest. i can get cobra calipers and brackets for what walk in price you can buy the 99+ gt/v6. but thats $$$ i dont have. i had them in the shed and gave em a shot, we got the them loose, the outer boots were ripped and they got corroded there, we reassembled them and seem to hold. ill reinstall in a few weeks. the calipers i had on the car before 5 lug i rebuilt myself. we used to rebuild wheel cylinders but the china made ones are cheaper and easier.
i dont care for the green but the car has green accents on it already so i didnt bother to bead blast them. i prefer gray for calipers, well see how i feel when i reinstall them.

Congrats on the wedding!  Very understandable on the $$$ and let us know how the PBR's work out once you install them.  I did this on my Coupe years back and they were a huge improvement over the stock 94-98 front calipers.  You will need to install a manual proportioning valve and gut the factory on in the combination valve as the balance on the car will be all out of whack with the additional stopping power up front.  Try it without it first as you may be okay with it but I was not.

I wonder how much difference in pedal feel one would have with the only change being FROM '94-98 calipers TO the PBR '99 units...

If a person already has the SN95 master cylinder and booster installed I can say from my own experience that the pedal feel is no different what so ever as it took the same amount of brake pedal effort.  Now the braking bias will be out of whack but that's another story.

Jack Hidley with Maximum Motorsports is a guru on this subject.  He posts pretty regularly on several sites, here is one of his posts on the Corral that is a good read:

Darren thanks for the info.
i actually vacuum bleed the brakes re-installing the single piston calipers and the pedal hasn't been this nice in a few years.

where is a vendor i can get a quality manual proportioning valve.
i have a sn95 master and proportioning valve i can guy or just gut the TC one. im tired of Teves it pulls to much current on the system. plus new parts are pricey for this teves.
would the braided SS hoses help with pedal feel and stopping ability or is it overrated?

You can get the Wilwood proportioning valve jsut about anywhere:

http://www.maximummotorsports.com/store/index.php?main_page=product_info&products_id=687

Just gut the TC unit and install the FRPP plug.  Maximum also has the plug and the installation instructions are at the bottom of the page:

The braided hoses are nice and in all honesty I doubt you would feel a pedal difference just tooling around town but in repeated hard stops they are much safer and do not swell like the rubber lines.  These are for the fronts so you don't need the adapters on the hard lines:

This is what a person should get for the rears if they have not already converted the car:

http://www.maximummotorsports.com/store/index.php?main_page=product_info&cPath=49_144_469&products_id=1438

I will say a person can do it cheaper but this is bolt on stuff for the average guy who does not want to flare lines.  The prices on MM site are list but if you go through a dealer like http://www.chicane23.com they should be cheaper.  Basically that was a shameless plug for my buddy John George's business ;)

So im resurrecting this post.
about a year later i bought reman calipers and brackets. those have been working flawlessly since.
in late 2018 i replaced the Ole Teves brake booster with 93 Cobra Booster and Master cylinder.
this months project is now upgrading to 13in rotors calipers.
also order ford racing M2300M kit for rear axle brackets and rotors to upgrade the rear also.
just waiting on rear bracket kit and stainless hoses for the front. ill make another post about all that.
