Title: cobra front brakes
Post by: amphibious6 on October 09, 2010, 11:00:25 AM
Hi all, I have a 1980 Pinto which i have swapped a 2.3 turbo motor with a few modifications. I really need some more stopping power and have located a set of cobra calipers with 13" rotors that Id really like to use. My question is what would I have to do to convert to 5 lug to fit these rotors. As far as the caliper I can make an adapter plate. Any information is much appreciated!
Thanks

I dont know if the Cobra rotors will fit easily but here is a brown sedan I saw pics of with Cobra wheels & calipers.

If thats too much work you can do what I plan to for my V8 car. 11 inch Granada rotors & a pair of 4 piston Wilwood calipers I got off Ebay cheap. All I need to do is make a bracket to bolt the caliper to the spindle & it sounds like you know how to do that already.

Thanks for the reply! After posting I found that same topic, and explored my options. I would really like to get a hub, like the ones from wilwood, to allow the pinto spindles to accept a 5 lug rotor and wheel. That would give me a wider variety of rotor sizes depending on the size wheels/ what I want to do with the car later on down the road. However the ease and cost of the Granada hub/rotors with an upgraded caliper looks pretty attractive.

I'm always looking for the cheap way to do things with good parts. It took 2 years to round up the brakes that will now end up on my parts car since my son wants my hatch. I found a set of new polished Wilwood calipers & pads for $200 on Ebay & they require at least a 10" dia. rotor so the 11" Granadas are perfect. $95 a pair shipped & the Chevy bolt pattern I need to run the pizza cutter Dragstars that have been sitting in my garage for 8 years kills 2 birds with 1 stone. With bearings & brake lines I'll be at half or less than the cost of the Wilwood street brake kit. It's a simple bolt on & the only work involved is making the caliper adapter which will look similar to the ones they sell so you can run GM Metric calipers on Granada rotors. I can't think of a better set-up for the money. If you are skilled at fab work it's the way to go.

silly question, if you are putting pizza cutters up front (skinny tires), why are you bothering to upgrade your front brakes?  It will most likely result in flat spotted front tires since you increased the braking while decreasing the contact patch.  Not a flame, just looking at the common sense of the upgrade.

There are several reasons including the cheap price. I also have Wilwoods for the rear that I got cheap that are 4 piston as well. I wanted to get the piston area close front to rear even though I think the rear has slightly more. I have a Wilwood master cylinder & with correct proportioning I can avoid front lockup other than a panic stop. There may be a point where I tire of the big n littles & go with some sizable rubber. The brakes will be sufficient to handle nearly anything. Also it will be a V8 powered street car & I want overkill on the brakes rather than regret & a future upgrade. This set should handle anything I throw at it. Lastly having 11 inch brakes & 4 piston Wilwoods at all 4 corners on a Pinto is an attention getter on cruise night. Doing it for the cost of replacing the stockers is a bonus.

The brown sedan is my car. If your going to keep your stock spindles look at mustangsteve.com. He sells a kit for the stock spindles to bolt up 13" Cobra brakes. But honestly by the time you buy the kit, the V8 hubs you need, and the Cobra brake setup, you could get a nice wilwood 4 piston kit.

Reason I went with the Cobra Brakes is because I had 2 sets that I got for practically nothing and I had the wilwood spindles off another project. So I made my own brackets with some material I already had. Other wise it wouldnt have come out so cheap. But that big rotor and caliper sure do look nice and stop on a dime. BTW if you do it get a wilwood adjustable proportion valve!

Hey guys, I also need to upgrade the brakes on my pinto. It has stock discs in front and Thunderbird Turbo Coupe discs on the rear.
It has the stock Pinto master cylinder.
I'd like to upgrade the front rotors to a larger size (I have 15" inch wheels), but dont know whats the first place to start.
I like the idea of Granada rotors, but finding them in the salvage yards is impossible anymore (every Granada is stripped of its brakes as soon as it hits the yard).
Are the bearings the same between Pinto and Granada??
I assume I'd need to use Wilwood calipers too?? because stock Granada calipers wont clear??...not sure on this.
All this stuff bolts to the stock Pinto spindle?? or maybe I need a custom made bracket to adapt the calipers??

What about my master cylinder...do I need one thats valved for 4 wheel disc brakes instead of disc/drum??
Do I need a adjustable proportioning valve??

I have a 80 that I want to convert to five lug, my problem is that I know very little about that conversion and I am not skilled in fabrication or adapting. I don't need much better brakes, I just need it do be 5 lug. What are my options? Thanks
Will

This is what you are looking for & it is a bolt on for '74 & up Pinto spindles. You definitely need an adjustable proportioning valve. I think your master cylinder is fine but a Versailles M/C is already F/R disc ready but I dont know if it bolts on.

So this kit is for a 74 & later spindle. My car is a 72, so will a 74+ spindle simply bolt on??

I know there is a way to swap them. search the archives for swapping early spindles & see what you get.

Those ebay ads above quote 7/16" studs.  I suspect this is a typo, but it is worth verifying (should be 1/2" for Ford).  Below is a link to the great thread that turbopinto72 started for 71-73 Pinto's.

Aftermarket street rod stuff is probably 7/16" studs. They are plenty strong.
