The system (Hydro-Electric) for the power top and windows recommended Brake Fluid ....... Be very careful because of what it will do to your paint if there is a leak in one of your cylinders so use Silicone brake fluid — DOT 5 — is silicone-based with a high boiling point suitable for motorsports, isn’t sensitive to absorbing moisture and doesn’t damage paint. But it is not compatible with conventional fluids. DO NOT MIX WITH CONVENTIONAL BRAKE FLUID SO YOUR SYSTEM SHOULD BE TOTALLY FLUSHED BEFORE INTRODUCING THE NEW SILCONE DOT 5 FLUID. Please do your own investigation to confirm this info.

Hi John--I'm restoring a 53 70 series convertible Skylark and used modern automatic transmission fluid in both the Dynaflow and the hydraulic pump powering the top and the windows. Modern transmission fluid called ATF replaces both of the types of transmission fluids sold in the 50s.

It seems a tough job getting to the pump reservoir underneath the RF fender but it can be done.
