57 slow vacuum wipers

I treated my wipers with brake fluid several years ago and they still work well. It is very simple. Buy a bottle of brake fluid and affix a length of rubber tubing to the air inlet on the vaccuum motor under your dash. Put the other end of the tubing into the bottle of brake fluid. Start your engine and turn on the wipers. Run the whole bottle through the wiper motor and your problem should be solved. You will also emit a large cloud of smoke out of your tailpipes. This will lubricate the leather in the vacuum motor.

Good luck. Hope this solves your problem.
 
So I have the issue I've read about here, the super slow vacuum wipers. Does anyone have the link to the brake fluid "trick" that seems to help quite a few of you?

Thanks.
Here is the link that you were asking for.


OhioTbird where in Ohio do you live? I'm the President of The Classic Thunderbird Club of Northern Ohio, here is the link from CTCI.

I wouldn’t say that you are in no man’s land, but since I’m in the Cleveland area I’m too far east from you. I have club members as far west as Huron, as far south as Mansfield and as far east as Beaver, Pennsylvania. The Ohio Valley Early Birds are primarily located in the Dayton and Cincinnati areas and the Maumee Valley Thunderbird Club is in the Toledo area. It would be nice if you could join a Thunderbird club. In my opinion, the best part of owning my T-Bird is being a part of this special group of people.

So the brake fluid won't harm anything? I just assumed they were slow by nature. Especially when one would accelerate and the vacuum dropped. Ford loved vacuum actuators well into the '60-'70s.

Success! I followed the instructions and was surprised to see it sucked down the fluid in about 60 seconds. A minute later, the wipers were firing back and forth like new.

Only thing I wasn't prepared for was how much white smoke I had. My white car in a light gray barn literally disappeared. Opened All the windows and doors and let it run. Took maybe 10 minutes to clear out. But now the wipers are good. Thanks for the advice.

I would recommend changing your oil and filter as both are now contaminated. Brake fluid and oil do not mix. Brake fluid will surely deplete the viscosity of the engine oil when it was sucked into the engine through the intake Manifold. So while this might make the wiper motor work better it will likely do permanent damage to the engine internals.
 
I have done this on many vehicles with a sluggish vacuum wiper system and have never changed the oil afterward. You are only using a pint of brake fluid and as the brake fluid enters the engine it gets burned off through the combustion process. The brake fluid does not mix with the engine oil, that's why there is some white smoke from the exhaust as the brake fluid is sucked into the engine. It will not hurt the engine and the smoke clears up after all the fluid is purged from the system.
