of Granada front disc brakes on early Mustangs has become a very popular way to convert
drum brake Mustangs to disc. But, as with most swaps, it is not a slam dunk as most
people have been told. If you are considering this swap, be aware of these minor
problems you will have to deal with.
1968 to 1973 Mustang, Torino, and other
Ford front disc brake setups will also work.
Almost everything below will apply to many other Ford setups. Don't count them out when trying to add disc brakes!
spindles are not a direct bolt on like the Granada and Monarch units.
Although all of the other parts such as rotors and calipers are the same, the Versailles spindles have a larger hole for the lower control arm ball joint. This hole either has to be filled and then re-drilled to the correct size and correct tapper for the smaller diameter ball joint or you have to adapt the Versailles lower ball joint to the Mustang lower control arm. Both of these options are doable, but can cost a lot more money than just using Granada or Monarch spindles to begin with.
3) The outer tie rod ends will need to be changed.
Mustang outer tie rod ends are the wrong diameter and you will need to change them to make the swap.

Style Steel Wheels and
some other factory and
aftermarket wheels will not fit on the front rotor.
The diameter of the snout on the front rotor is too large to fit up into the factory and
reproduction Style Steel Wheels. This problem also effects many stock factory steel wheels
and aftermarket wheels with small center holes. The result is that you have to take the
rotors to a machine shop and have the snout turned down to fit the wheels. Before doing
the installation, check your wheels on the rotor! (This does not apply to 1968 to 1973
Mustang, Torino, and many other Fords setups! The snouts on these rotors work just fine
with stock wheels. However, these rotors are more expensive!)
Brake lines have to
be adapted for 1965 to 1967 Mustangs.
The caliper sits on the back of the spindle instead of on the front like the factory set up. This means that the brake hose is pointed towards the front of the car instead of the rear. But this is a simple matter to take care of. The brake line has a large mount on the end opposite the caliper. Loop the brake line around the sway bar end link and attach it to the frame right under the upper control arm. Then, using a 8" to 12" section of hard line, use an adapter line to go from the factory hard line to the brake hose. Connect the two hard lines with a double female adapter.
