Does anyone know of an alternative emergency brake step up other then cable just completed my rear disc on my 79 elkie need emergency brakes :P

You could use a line lock. Which disk setup did you use?

Check this: http://hometown.aol.com/smartasreality/page08.html Seems like a reasonable solution that is effective for everyday use.

I used the rotors and brackets and cliper from a 85 camaro original rear from my elkie were can i get a line lock

I've been looking for this same conversion for my '79. Did you have to modify the brackets /backing plates at all? Everything I have found has the "Square" bolt pattern, where my rear has normal holes on top side of the axle housing and closer very small holes on the bottom. Also, what type of e-brake setup was on the Camaro rear originally?

Try a speed shop for line lock, as it's standard drag equipment.

There was also someforeign car (Subaru?) that had a "hill holder" for standard trans cars -- held the brakes for you while you had other feet oddupied with gas and clutch -- for those who hadn't learned heel&toe. ;-)
