How to Install 14 Inch Brakes on an A-Body (or B/E also)
Installation day.....
The bolts securing the adapter to the spindle are 1/2-20. The fasteners securing the adapter to the caliper are 12-1.5 socket head cap screws that fit into the counterbored holes on the adapter.
First the existing setup:
Removed the existing rotor and caliper and mounting bracket. Also had to reverse the steering arm/lower balljoint bolts to clear the new hub:
Then installed the new adapter bracket to the spindle using the 1/2-20 bolts. Finally, installed the new rotor and installed the new caliper using the 12-1.5 socket head cap screws:
Total cost for this project: $1385, not counting pads of your choice. We are using Hawk HPS pads. Wheels are not included in this cost.
Caveat: A word of warning when selecting wheels for this mod. We found out the hard way that not all wheels will fit the 4-piston calipers. You need to check with the manufacturer on this. In the end we selected Forgestar F-14 wheels, 18x9 with 40mm offset. The rear wheels are 20mm offset.
