ooops, I hadn't noticed that the stainless steel brake system was the SSBS folks that have not resolved the various complaints.
I'm considering having my front brakes changed to disk while leaving the rear brakes alone as drums. I would install a different proportioning valve and adjust it to balance braking effort front to rear.
I want to stay with the stock 14" wheels. I just noticed the stock spindle kit from CPP required drilling out the steering arm and "works with most 15" disc brake wheels".
Their drop kit will fit 14" wheels but the stock one won't. Interesting.
So, I guess I need to keep looking.
Are there any parts on later model Nova or Bonneville etc. that can be bought as replacement parts and installed to configure disc brakes?
