greg g Posted October 3, 2016 Report Share Posted October 3, 2016 Don't want to use adjustable or channel lock/vice grip. Tried all my sockets, either too big or too small. Quote Link to comment Share on other sites More sharing options...
casper50 Posted October 3, 2016 Report Share Posted October 3, 2016 (edited) 15/16 is too small and a 1" is a bit sloppy on my 47 dodge switch. Edited October 3, 2016 by casper50 Quote Link to comment Share on other sites More sharing options...

When we got to the restaurant my son ask me if I ever used the brakes as there were no brake lights visible on my car. I said yes I used the brakes every time I stopped. Next day I pulled the wires from the top of the switch and shorted them together. The brake lights all lit up so I know the switch was at fault. I found one on Amazon for ten bucks and placed the order. https://www.amazon.com/Wells-RB401-Brake-Light-Switch/dp/B0026N52ZW Several years ago I installed a mechanical switch in my P-15 to replace the hydraulic switch that did work but the mechanical switch works better as the brake light comes on as soon as I tap the pedal without pushing it far enough to build pressure. So for a quick fix I elected to swap the hydraulic switches from one car to the other. I now have working brake lights. The location of the switch is elbow deep under the hood and it is difficult to spin a wrench. So I elected to use a 1" deep well socket and a couple of extensions so I could spin the ratchet wrench without obstructions. This made the job a whole lot easier and quicker. 52b3b Joe and JBNeal like this Quote Edit Don Coatneyhttp://smg.photobucket.com/user/DonCoatney/library/#/user/DonCoatney/library/?page=1&_suid=137807490533204519373465134713 "Just remember, once you're over the hill you begin to pick up speed."

austinsailor Posted October 3, 2016 Report Share Posted October 3, 2016 There is a special socket for those. They are not hex and neither is the switch. They used to be a common item, but may be hard to find these days. Quote Link to comment Share on other sites More sharing options...

I'm pretty sure it was one of these. Like I said, I took the new switch in with me to test the fit. When I got home, I used the socket to remove the old switch and install the new one. This was on my 58, but the 37 and the 41 use pretty much the same pressure switch. Lee Quote Link to comment Share on other sites More sharing options...
