So, my 1967 mustang has drum brakes all the way around since its just a base 6 cyl car. I've heard of how people do granada disc brake swaps. At the time i didnt think much of it because i just thought to myself "where the **** am i supposed to get a granada?" but today i had the great realization that i work at O'reillys and order brand new granada brakes and get my discount and do a really cheap disc brake conversion on my pony. BUT I still need yall's help. what are ALLLLL the parts i need to change out my drums with granada disc? i already priced the rotors, pads, and calipers as you can see in this picture here.

also, what year granada do i use?
The year Granada is the mid to late 70s. You will also need Granada spindles, You can't just buy new calipers, pads, etc and bolt them on your car. I don't think you'll find Granada spindles in the Oreilly parts catalog.

Alternatively you could also just go with the stock 67 Mustang disc brakes too.

Look at CSRP or Chockostang for complete kits. This may bet the best way to go.

I suggest going with manual disc brakes with either a Maverick or Ranger 15/16 bore master cylinder. I have used both and like the Ranger one.
You have a 67, that means the factory ford disc brakes will bolt to your Spindle. Call chockostangclassicmustang.com and he'll sell you what you need to do the swap. The Grenada swap was a great option when we had little to no other option. Now, not so much.

The reality is the Granada disc brake swap was popular because, once upon a time, you could go to a local salvage yard, find lots of Granadas, pull the front brakes, bolt them on an go. Cheap and easy.

So, today you can buy brand new Granada brakes. But why would you want to? As mentioned, you can also buy brand new Mustang brakes. Do that. Dan is your man.

I commend you on your desire to upgrade. But honestly at your age and price range, a good rebuild of the drum brakes will get you down the road and stopping safely. Make it safe, make it reliable, then make it fun.
I would skip Granada and look at Mustangsteve for big brakes or go oem style.

what does a rebuild of the drum brakes include? i already have new brake shoes and hardware that i need to put on. I was just looking at my disc brake options so i have an idea

A complete rebuild would include drums, wheel cylinders, adjusters and springs. All that stuff gets completely shot after 50+ years.
Drums are probably ok. I replaced the steel brake lines, master cylinder, hoses, shoes, hardware, bearings and had new axle bearings installed for under $300, that included new rear drums.

With less than 100 miles on the fronts I tore the car apart for an engine swap and went to discs at the same time.

Zackary, I'm an hour south of Atlanta, if you were closer I would give you the fronts. All they need is to be installed and bled.
I support your desire for discs…I prefer them over drums. I replaced drums completely and then ended up removing them and going disc. Granada is great if you have them already, I have 2 sets of them on some of my cars. I’ve also done factory discs on my 70, and Kelsey Hayes on a 65. Chockostang or CSRP sell good kits. Go with mustangSteve if you want the larger brake rotors for larger wheels.
You have several options for your 67.

Chockostang for stock Ford originals.

Mustang Steve for brackets for late model Mustang brakes (99-04, 05-14, and 15-17).
You source your calipers on your own and any associated hardware and plumbing too.

Granada calipers work well with the semi-metallic pads for police/taxi use. Definitely not as abundant as they used to as it’s been used for all sorts of hot rods too.

The casting has D5 prefix…I always referred to them as ‘78 Granada (that was my donor) for replacement parts. Also used 78 Granada as my reference for Duraspark parts as well for my 289.

Personally, stick with the 67 spindles and you will have many options available from stock to late model stock to aftermarket.

the front what? disc? or drums?
Summit has great prices on the basic wilwood kits.


Bought the same kit for my 65 and they installed easy and work great. Also keep in mind that if you install discs you need a master cylinder for disks up front preferably one with a residual valve for the rear brake or you will have to install a 10lb residual valve as well.

Master cylinder for Disk/drum and Drum /Drum are different. Disk brakes need larger amounts of fluid and thus have larger reservoirs. A dual drum MC has two reservoirs te same size.

If you Intend to keep the car a 6 cyl, you don’t need anything special for brakes. Your best bet it simply installing the original Kelsey Hayes disk brakes Ford installed in 67. Chockostang can set you up with all you need, The bigger Mustang Steve, Wilwood, and other options are way overkill for a stick 6 cyl. The Granada option is more trouble than its worth in your case And offers no better performance.

I’m another no vote for Granada. Much better complete options available. I did 67’ Kelsey Hayes CSRP swap manual kit on my existing V8 spindles. Power brakes are much harder to install and really not necessary in these cars. $650 for a truly complete kit with good instructions.

Chockostang is a great option too, I have many of Chock’s parts (steering system) in my car and he will give you the best individual help/attention and support you could ask for.

Look at Chockostang, OpenTracker Racing, & Street or Track. They'll all have full kits with every nut, bolt, washer, hose, etc. I think NPD also has a full kit. SoT has a number of options, from stock K-H to mild to wild, including Wilwood and Baer.
