going to manual brakes in a late B

Parts you will need: pushrod kit #P5249316 ( Mancini#MRE316). Mancini adaptor # MREAR6718. Everything else ( including the master ) you can use over again. You will have to remove a good portion of the dash ( and that 11 pound cast iron weight ) in order to get to the bolts that secure the booster to the firewall and brake pedal and Z style linkage. Pic 1801 shows the brake pedal arm on the right and the Z style linkage used with the booster. The linkage won't be reused. Pics 1801 and 1802 show the modified brake pedal arm with the pushrod pin relocated 2" down from the center of the brake pedal pivot ( part with the plastic incerts ). I came up with that 2" from the pivot to the pushrod by measuring a full size 65 Dodge with manual brakes. I reused the pushrod pin by pushing it out of the original hole, drilling and taping the back side so I could bolt it back in to my newly drilled hole ( pic 1802 ). Pic 1803 shows the original booster hole ( upper hole ) and mounts ( very top holes and middle of the bottem 3 holes ). I had to drill the bottom large hole for the stock master Cylinder to go through and the very bottom bolt holes and third holes up for the adaptor to attach to the firewall and brake pedal / steering column support ( pic #1806 ). Surprisingly, the brake pedal support was already drilled for this location, so I just had to drill throuigh the fire wall to catch these predrilled holes. This lower master location puts the pushrod in the proper position for a straight shot between the pedal pin and the master ( pic #1806 ). Pic #1804 shows the adaptor in place on the firewall and pic # 1805 show the master in place with a little aluminum pannel I made to cover up the existing booster hole in the firewall. This mod just removes the booster from the braking system. All other brake components from the master to the brake shows were used over again ( stock to the 79 Cordoba ). The stock Cordoba master has a 1 1/32" bore. Went racing last weekend and the manual brakes worked great. Just like a "normal" manual brake car. I was easily able to stop my boat from 117 MPH and could lock the brakes up any time without excessive pedal pressure. http://s79.photobucket.com/albums/j1...y/DSC01801.jpg
