The power brake conversion bracket (65-66 Only) is a 10 ga. steel bracket that is welded to the front of the pedal support bracket (under the dash). It provides the support and correct bolt pattern for the power booster. The pedal support assembly then bolts back in to its original location, with 2 additional holes required in the firewall plus enlargement of the original center hole where the master cylinder fits. It provides a very nice, neat, factory looking booster installation, tight against the firewall, that can mount a dual piston master cylinder or you can use the original Mustang master cylinder
The pedal pin (65-66 Only) where the original master cylinder hooked up to the brake pedal must be replaced with a new design pin in a new location on the pedal and welded into the pedal arm. This weld must be done by a competent welder! The new design pin, having a flange added on the pin side of the pedal, allows the new pin to be welded from both sides of the pedal arm, which makes it virtually indestructible, and stronger than the original Ford part.
The original pedal-mounted stop light switch is utilized, but it is best to change to a 70 Mustang power brake stop light switch so the lighter pedal pressure will still trip the switch under light braking. Pedal height is slightly lowered, like a factory power brake car would have. (Remember, it takes less travel to actuate the power brakes due to the revised pedal ratio, and the lower pedal makes for a more comfortable driving position). Two metal brake lines must be fabricated to reach from the master cylinder to the proportioning valve or to tie into the existing lines.
(This conversion fits 1965-66 Mustangs with automatic transmissions. These kits will fit standard if you have cable or hydraulic clutch only)
