  • Burning Brake Fluid?

    I have a 63 Hawk that is under construction. When starting, which is occasionally, I get alot of white smoke from the left tail pipe. I mean fill the garage full of smoke. I was thinking a cooling system problem but the wet stuff that comes out the tail pipe when first started is oily and bitter tasting. It doesn't smell or taste like I would expect a coolant leak to be. My coolant level is staying the same, but I am loosing brake fluid from the firewall resivor. I filled it twice and can't see any leaks under the car. Is it poosible for the car be burning brake fluid through a poor installation or a defect in the power booster?

    Maybe...
    Pull and plug the vacuum booster line and start it up...
    That'll tell you if it is the booster or not.

        If your master cylinder was leaking fluid onto the exhaust pipe it would burn off at that location, not come out of the tailpipe. Since you have a power booster I imagine it might be possible if the seals are bad, fluid could leak back into the booster and get sucked into the induction system by vacuum and get burned in the combustion chamber and residue out the exhaust. I would think it be come from both tailpipes but the intake could be directing only one way in a dual-plane intake. Just a guess on my part...don't know how possible that might be.

        Another reason for a leak could be a leaking wheel cylinder but that wouldn't account for the residue in the exhaust.

          Mix it with a chlorine bleach tablet and find out (outside!!!)

            It's possible that your booster is sucking brake fluid out of the reservoir and into the engine where it will burn. My Avanti had a leaking master cylinder and the booster sucked in the fluid causing the booster to fail. DOT 3 brake fluid is alcohol based which is why it will burn and also remove paint from your car's fender. Bud

              Had the same problem with my 63 Hawk with Hydrovac booster as well a number of years ago... white smoke (mostly visible on start up), and yes, mostly out the left exhaust pipe. With that symptom, and losing brake fluid, pretty good chance that the seals are gone in the Hydrovac(although I couldn't tell you which seals). Jeff's suggestion is a good one: Pull and plug the booster line and start her up. Might be some residual fluid, so may want to try a couple times and see if it clears up.

              Good luck!
              Best Regards- Matt

                Thanks for the encouraging words. I've removed the booster hose and have started it for a couple of 15 min runs and the second running seemed to have a major reduction in smoke The car has been run for at least ten years and everything except engine oil has leaked so far. A head gasket would be cheaper for me to fix but I didn't want to tear up something that's not broke.

                  Check for traces of brake fluid on the inside of the vacuum hose, that should tell you something. Russ Farris

                    I also had the disappearing brake fluid mystery. When I took the hose off the bottom of the Hydrovac, it ran out all over the inner fender.

                      Me too. I then had to repaint the engine bay and the front cowl. Be careful with that brake fluid.

                      My bet is the hydrovac vacuum line. Pull it off from the manifold and watch the fluid come out of that hose.

                      You need a rebuild of the hydrovac. Get plenty of copper washers for the connections when you order the rebuild.
