Now I'm wondering if there's a nifty drawing like the one above for a Task Force truck? GOnna search here and on Stovebolt. Anyone know anything about this?

NEWFISHER · 01-17-2013, 09:23 PM

When I get ahold of Ghostrider I will ask if the rails and mounting holes are the same.

Anyone have a club meeteing or a buddy with one or the other to take some measurements?

Thanks it would be great if he has that info.

Trekster · 01-18-2013, 01:35 AM

Autozone P/N of Mustang M/C - NM1485
$66.99, has 1 inch bore

NEWFISHER · 01-18-2013, 01:51 AM

Good info Trekster, thank you
I'm going to stick with GM if I can, but for those with MII Ifs that's a great option.

Isn't it irrelevant if you're using a Mustang-based IFS or not? Am I missing something?

Besides, that $67 MC is more expensive than the $40-ish for the Nova, Chevelle, C10 one so why would I use it? Is there an advantage I am not aware of?

NEWFISHER · 01-18-2013, 02:43 AM

It will do the same thing, but its designed for a F*%D, I just want to stay all GM hence my choice of the malibu, nova or corvette. If I was going to do an IFS front, I would graft in a monte, camaro etc. Not knocking the MII, but its just "the other brand" than what I'm used too.

I'm also going to use a NEW master and not a rebuilt one, so the $$'s will be in the $40-$50 range

Got ahold of ghostrider. He builds and ships the brackets for $50. Reids52@aol.com is the best way to reach him.

**Dan in Pasadena** · 01-20-2013, 02:52 PM

Too bad he doesn't make any for the Task Force trucks! Doh!

Have you checked with him? He does several variations depending on what you are doing. Ie corvette, c10 etc.

**Dan in Pasadena** · 01-20-2013, 03:02 PM

No I haven't so I guess I should. I'd use a $20 "special" from Rockauto and save a bunch.

If you haven't already purchased, you may want to give Ralph a call at ECI he has some good info and prices. He will "engineer" the M/C to the size of the wheel cylinders. I have used his products on the last three trucks

**Dan in Pasadena** · 01-23-2013, 03:10 PM

No, I haven't purchased the master cylinder yet. Thanks for the head's up.

I bought (what I think is) a CPP kit, new-in-the-box with the brackets, calipers & bearings from a guy who had bought them for his '54 and then sold it. He SAID they'd also fit a '55-'59 and I did a little research at the time and it seemed to be correct info. This stuff has been sitting in a drawer in my garage since I found out I didn't have enough vacuum to run a power boosted MC. Now that Rude Dude has clued me into an alternative approach without swapping the cam I want to get this upgrade installed! I'll look into ECI and give Ralph a call. I've got an unknown 10 bolt rearend in my truck and of course the CPP calipers which are...what? Probably Camaro calipers? Possibly C10's?

NEWFISHER · 01-23-2013, 05:02 PM

I pulled the trigger and am using the $50 bracket kit shipped from ghostrider aka Steve or reids52@aol.com. He has a few C10 master brackets already made up and would have had to make one for the Corvette cylinder. I am using a NAPA 1" bore drum/drum master for a 1970 C10 2 wheel drive part number NMC M1880 here:
http://www.napaonline.com/Catalog/Ca...880_0358745331

I chose that one for a couple reasons. Readilly available locally unlike the GM A/C Delco one, its NEW not cheap rebuilt and it has a single wire snap cap instead of dual wire. I thought messing with 1 wire cap under the floor board would be less hassle than a 2 wire set up.

Once I get the bracket, some hardware, a dedicated rear line and cut down a 3/8 rod to fit, I will start taking some pics and detail the swap in case anyone wants to follow along.

Again, I am running drum /drum and using a master cyl for drum/drum or disc/disc so it will work for my application. For those running front disc, there are other choices out there or you can install a manual adjustable valve to dial down the front pressure and use this same cylinder. For those running drum/drum or disc/disc and getting a disc/drum cylinder you MUST remove the restricor in the forward port to equalize pressure for your drum/drum or disc/disc system.

Perfect.....thanks!!

55dude · 07-30-2013, 04:28 PM

I do realize this is for a non power conversion but has anyone done this including a power booster? I'm interested in doing this on a 52 3100. Thanks.

sqrlnts · 07-31-2013, 12:19 AM

Subscribed for future use. Thanks for sharing the swap info Newfisher, I am curious at the total cost involved.

$50 bracket and rod, $52 master cyl and $20 in brake line/fittings etc. It's in a pile waiting for me to stop driving it long enough to make the swap.

**Dan in Pasadena** · 07-31-2013, 01:47 PM

Since this thread was last active - back in January, I found/bought a new, unused CPP frame mount bracket, non-boosted dual MC & the adjustable proportioning valve all for $150. CPP sells the kit for $219, so it was a good deal.

Of course I haven't installed it yet. I've gotta order a tube bending tool of some kind and (from another thread) it looks like I'll be going with the nickel-copper, easier-to-bend lines already flared from Jeg's....probably.

**Dan in Pasadena** · 07-31-2013, 04:12 PM

Anyone have anything good/bad to say about THESE bending tools:

Amazon.com: Eastwood Brake Line Tubing Bender and...

...cause I JUST ordered them! Hope I won't regret the expense. There were cheaper ones, but...

_Ogre · 07-31-2013, 05:38 PM

i have a similar bender. it's ok but the radius is a little big and it grips to far from a fitting to be usefull. the pliers look like more for tweaking bends.

a dedicated 3/16 bender is best. this one is on ebay has a 5/8 radius and grips closer to the fitting. i was able to borrow one of these when i did my brake lines. see if you can borrow a nice one, you'll only use a 3/16 bender for brake lines

this one has a tighter radius. also sells for $130

**Dan in Pasadena** · 07-31-2013, 07:54 PM

BORROW ONE? When I JUST spent $60 buying one? I don't think so.

I'd read about the Eastwood one a couple of times elsewhere and the pliers were recommended too. Seems like a 1" radius ought to be tight enough but I guess we'll see. I know to make a sample piece using a scrap piece of tube in varying degrees.

Has anyone done this upgrade with a power booster keeping the drum brakes? With the duel master cyl. Upgrade also.

Did he make the rod and bracket for $50?
