My 68 442 convertible has a front disk brake conversion kit installed (previous owner) but the brakes feel like there isnt any power assist. The booster will hold vaccume and the the engine is generating vaccume,how much I dont exactly know. What can be the problem and what should I check next? Thanks for any info! Thanks!

 

What hole in the brake pedal is the pushrod in?

It should be in the lower one. Make sure you've got a 1 1/8 inch bore on the mc.

 

Was the proportioning valve changed to disc brakes?
They're different!
