If I buy a donor 3.0 S Type will the braking system be interchangeable with my 4.2, have had a problem with complete brake failure 😁

 

I'm sure some parts are interchangeable but consult JPEC using the VINs of the two cars to be sure.

I can't imagine a brake system failure requiring every component to be replaced. If there's just no brakes at all, it's usually the master cylinder
