Disc Brake Master Swap & P valve Question

Thanks for the reply.

So did you just swap on a disc brake master cylinder and that was it (assuming you had drums to start?)?

I guess I should fill in more just to be sure on my car. Swapped an 8.25 rear in that has the 10" drums on the back instead of the 9's that the car came with. Front disc are already on the car, but are the older type.

Just want to be sure it is safe and no problem with rear lock / control loss upon a semi panic type stop on the highway or the like. Amazing the number of people who pull across the median on the highway to turn around and then pull right in front of traffic going 75 plus and do about 20 while they suss out who's calling them on the cell phone!

Thanks for your help.

Cheers
