Want to save some money putting rear disc brakes on your old Ford small bearing 8" or 9" rear end? Yes you do that's why you are here.
This is not the Explorer Disc brake swap. That is for the
"large" bearing axles found in1974 on up cars and trucks.
This is the setup you are looking for. Now, go back and read this
again, these are VERY important dimensions that you need to
confirm on your 8" or 9" inch housing and axle. Just because
you have one of the listed cars from the listed year does NOT mean
you have a small bearing housing. It is easy to swap a large
housing into these vehicles. So check BEFORE you start
1992 to 1995 or 1996 to 2002 - Crown Victoria,
1992 to 1995 or 1996 to 2002 - Grand Marquis'
1991 to 1995 or to 1996 - 2002 - Lincoln Town Car
Note there are 2 different sets of years. The early (91,95) years are a little less expensive when it comes to replacement parts. The later (96,02) use a different caliper with slightly different mounting points. So you can not mix the sets.
Note no dust shields in 1991. 92-95 shield is removable. 96-02' shield is not-removable.
ALSO NOTE !!! For 64 to 66 cars the axle housing is slightly shorter then 67 newer housings. So you are better off using the 91 to 95 parts because of some clearance issues with the springs. The caliper mounting bolts on 91 to 95 cars are shorter giving just enough clearance.
You will need from the donor car
The rotors and pads I wouldn't worry with. They are cheap to replace and most likely worn out unless you are lucky to have found a wreck with good service. My local yards did not have many of these cars available. The only one I could find was a complete rear for $200. There are several sellers on ebay offering good deals for the parts. They will save you time in the yard. Some will offer to send new rotors and pads for a few extra $.
Because of differences in the old and new parts, spacers are needed in certain places to keep parts from moving around when installing the brakes. You will also need to modify your axle housing flanges so that the backing plates bolt up properly.
A bearing spacer must also be installed on your axles. If you
cannot do this yourself, plan on having new axle bearings
installed, along with the spacers by a professional shop.
You probably need new bearings anyway. Do NOT I repeat
do NOT attempt to press off your old bearings and then re-use
them. The bearing is what holds the axle in the
housing. They stretch when pressed on and will be loose if
you press them on a second time. This could result in
the axle sliding out of the housing. New bearings are cheap
compared the the hours and $ spent on your ride!!
If all else fails you can simply bolt the Drum brakes back
on. You will make no modification that prevents this.
