Kit: This kit is for the 66 - 77 Big bearing axle with 1/2" studs.
Details:
All of our rear disc brake conversion kits use G.M. single piston calipers: These kits use D-154 Pads, Fits 7" Axle flanges without machining the axles, and use 1" wide rotors.
If you aren't worried about parking brakes they will work with the front calipers from a 78-83 Monte Carlo. Those looking for the e-brake setup you will need the rear calipers from a 79-85 El Dorado, Riviera, or Tornado along with the miscellaneous parts for the linkage.
You may also need to move your shock mount inboard 3/4".
All kits require our stainless steel hoses to tie into the existing brake system. Custom hardware needed for the swap is included. This saves in the cost and allows you to locate the additional parts locally (parts store/bone yard.)
The rotors are custom pieces that are readily available for replacement if needed.
In some rare instances you may need to purchase an adjustable proportioning valve to achieve proper balance front to rear but usually the stock setup works fine if bled well. |
