Brake parts needed

joe53HH

I am finally getting around to doing the brakes on my '53 Hornet. I am replacing all the wheel cylinders and master cylinder because the car was sitting for a long long time with the previous owner and the brakes were not working so well. I also need to replace a couple of other items such as the parking brake cable assemblies (front and rear) and the play link assembly (BZ300658). Any suggestions as to where I may purchase the cables and play link? I also want to flush out the brake lines. What is a good procedure for doing that?
Thanks,
Joe
