1961-64 Buick; LeSabre, Invicta, Riviera, Electra

These computer-designed and CNC laser cut cold-rolled steel brackets are designed to mount on your existing 5 on 5" drum spindles with no machine work or modification required.  

They use GM half ton truck rotors and 1971-76 Cadillac DeVille calipers. These calipers are available as remanufactured units from rockauto.com as of January 2024. They may fit inside the stock Buick 15" rims if the calipers are trimmed. You will, however, need to realign the toe-in setting. 

We specify this caliper since the "normal" GM full size caliper has hose interference issues with the frame.

We actually bought a 64 Wildcat for fitting purposes and this caliper was the only one noted to work correctly.  Wilwood sells a 2-piston variant of the 1.25" D52 GM that may work also.
