Brake Solutions for Ford 8" & 9" Rear Ends

(Muscle Cars, Vintage Mustangs, Street Rods, etc)

North Racecars offers a variety of disk brake solutions.

All of our brackets require removal and reinstallation of the axle bearing.

If running 14" or 15", use the 10.6" rotor. If running larger wheels, we recommend the Cobra rotor and caliper for appearance.

All North Racecars brake kits retain drum brake offset. See chart and description below.

When deciding which brake to use it must first be determined which rear end is in the car.

First determine if the rear is an 8 inch or 9 inch with small bearings.  What is important is the bolt pattern on the end of the housing and the brake offset (see Diagram).

Most Mustangs and other late 60s Fords came with 8 in rears stock and many with upgraded horse power came with 9 inch rear ends but used the small bearing ends.  Ford did this to not have to make different brakes and axles for the same car.  The axles and brakes will interchange from a small bearing 9 inch to an 8 inch.  Most came with drum brakes and most came with what is referred to as the standard 2.5 inch brake offset (see diagram again).  Some came with the shorter 2.25 offset sometime listed as the 2.3125 offset.  Determining the offset requires more than just removing the drum in most cases.  It is best determined with the drum and drum backing plate removed.   Also the big drum and standard drums do not affect the brake offset.  We have seen 8 inch rears with big drums and then a 9 inch with standard drums and both had the standard 2.5 inch offset.

The same information is needed for the large bearing.  Look at the bolt pattern to determine which housing end is installed.

DO NOT LOOK THE SHAPE OF THE HOUSING END IT WILL NOT GIVE THE NEEDED INFORMATION, LOOK ONLY AT THE BOLT PATTERN THEY ARE NOT THE SAME FOR OLD AND NEW STLYE!   

There are many aftermarket rear housing manufacturers and many use the square housing end with the old style bolt pattern.  Also, many manufacturers also reproduce this housing pattern in the both old (D shape) and new (square style) pattern.  Again, the only thing that matters is the bolt pattern.

Once the bolt pattern and offset have been determined decide which bracket will work for you. 

Other notes:  We had 3 of 4 wheels that were 14 inch fit the GT brakes.  All 15 inch wheels we tried fit the GT brakes.  

For Cobra brakes wheels must be 16 inches or larger.  In our opinion, if running 17 or larger wheels run the Cobra brakes, they just look better.
