This is a complete bolt in kit that uses a modern power booster and dual circuit master cylinder mounted to the firewall using the bolt holes for the factory air box. It includes a new brake pedal that swings from a higher location (looks like it could be original too). A modern GM booster and master cylinder give a significantly improved braking feel and power while adding safety through the dual circuit system.

 

This kit fits only the 1957 Oldsmobile. It fits all models of 1957 Oldsmobiles but no other years or makes of vehicles.

 
This can be used with factory drums, disc/ drum or disc/ disc. Let me know what brakes you have at check out and I will send the correct proportioning valve.
 
It will have the pedal feel of a modern car- minimal effort required with a positive and firm feel. No more soft or sloppy pedal!
 
Installation is fairly straightforward- minimal cutting of the firewall behind the air box (you can always put your original airbox back on and it would never show) and drilling of 3 lower screw holes to allow for heavier 5/16 bolts. Takes about 2-4 hours to install. You have to remove the driver side air box, master cylinder, original bake pedal, cut out an area about 3" wide area to make room for the pedal linkage, and then this kit bolts in.
 

Please know that some Oldsmobiles have a very large metal air ducting underneath the dash and this kit requires that you modify that air ducting for clearance. I have not personally installed this kit on such a car so I do not have pictures or exact instructions. One look under your dash should tell you- it is a particularly large metal air ducting piece betwene the firewall and dash. 

 

All metal parts are CAD designed and cut on a CNC plasma table for consistent high quality results, then painted in satin black.
