REAR DISC BRAKE INFORMATION Housing Flange Chart, Diagram A
To order the proper Wilwood rear disc brake kit, check the following mea-
sure ments on rear end as sem bly and refer to the accompanying diagrams
to determine the exact housing flange and axle flange-to-housing flange
di men sions.
1. Outside bearing diameter (Diagram A).
2. Housing flange mounting pattern (Diagram A).
3. Stud pattern and bolt circle on axle flange.
4. Determining Axle Offset - Ford 9" and Dana rear axles, in particular, have
used varying axle to housing flange offsets over the years. This is the
reason it is very important that this measurement is accurate when ordering
rear disc brake kits for these applications. Use the drawing in the lower
middle of Diagram A to correctly measure this dimension.
Very Important: Custom-built or narrowed rear end housing may be equipped with a dif-
ferent make or style of hous ing flange. Be sure to order the mounting kit to fit the housing
Diagram A flange, not necessarily the make of the rear end. Example: Big Ford housing with Olds flange
requires an Olds/Pontiac Disc Brake Kit.
