Classic/Antique Car Repair/low brake fluid

Question
After following your suggested ride exercise, that is top speeds of 70mph, once off the main road and lower speed area,my braking came to a pedal to the floor situation. Quick inspection yielded low brake fluid. No Leaks. Do I just top up, check for air in system ? Next day showed level returning just short of normal. Is this due to the boiling point at high speeds or the prior owner not finishing the brake job of through bleeding? The Rolls Royce is a 1969 coupe. I read where Dot 3 can substitute in a situation such as this, true or false?

Answer
Hi John:
I think you may have communicated with another expert, as
I don't recall the process you describe or solution you describe.
Please send or reply to my original response, so  can see what
the original problem was. In any case, NEVER PUT DOT 3 BRAKE FLUID IN A RR.
IT WILL DESTROY THE ENTIRE BRAKE SYSTEM. ONLY USE RR363 Mineral Oil.

Expertise

I can answer most questions about autos built in the 1920 through 1990. Mechanical issues and technical questions are my expertise. I also have a general knowledge of most older automobiles. Keep in mind, I can only provide answers if the questions are very specific and complete. Without details, I can only speculate and that's not good for solving your problem.

Experience

I have owned and maintained Silver Shadows for over 10 years now. I find most mechanics and even Rolls Royce mechanics have very little knowledge about these automobiles. I have researched these cars in quite a bit of detail and can pretty much tell you what is wrong, if you can describe the behavior in detail. I have saved quite a few RR owners a lot of money and aggravation due to improper diagnosis. I am the owner of Classy Transportation, LLC a luxury limousine service specializing in antique cars, classic cars, vintage cars and exotic cars.
