Nissan Repair: NISSAN BRAKES, rear brakes, ford dealership

Question
I HAVE 89 300Z WITH REAR BRAKES FAILING ,PEDAL SINKING ,NO FLUID LOSS ,& COMPRESSOR IS SEALED WELL.BUT HAVE RAN DRY OF OTHER SYMPTOMS.

Answer
Change the master cylinder as it is leaking internally.  Do it soon because if it leaks out the back it will take out your vacuum brake booster.  Use Ford High Performance Brake Fluid when you bleed the brakes as it has twice the boiling point of normal DOT 3 fluid.  You have to go to a Ford dealership and ask for it by name.  The nice part is it is DOT 3 and works great with Nissan brakes and it takes about 3 pints to do your car.  At $5 bucks a can that is only $15 for a complete flush and you will love the difference.
