Replacing The Carrier
It is very common for axle lengths to change

Changing The Brakes
May alter many of the axle dimensions
• Brake Offset (F) may change requiring a different bearing stop (B)
• The pilot hole for the rotor might be different than your brake register (A)
• The flange OD (D) may need to be reduced to fit inside their rotor
• Their kit might be designed specifically for either a ball or tapered axle bearing
• Some require an access hole in the flange to tighten the backing plate

This Is The Brake Register Machined On The Axle Flange

OEM and most aftermarket street brakes use this to center the drum or rotor
This is usually unimportant with Drag Race disc brakes
They tend to have a very large hole and center on the wheel studs

From The Outer Face Of The Axle Flange To The Machined Bearing Stop

This measurement is never the same as the brake offset “F”
For an accurate measurement, the bearing & seal should be removed

This Is The Diameter Of The Axle Where The Bearing Will Press onto

This Is Necessary To Keep Your Brake Offset The Same
Remove the inner axle seal as it is no longer needed
The new bearing is equipped with o-ring for sealing

The New Style – With Spirolox® Retaining Ring
The ring secures the bearing between the retainer plate & housing end

The Old Style – With Peened-On Retainer Plate
The plate is fixed to the bearing

The new style is more secure
Some older disc brake kits require the old style

If your housing uses a inner axle seal, remove it.
It is no longer needed and will interfere with the new axle & bearing
