| I have done a disc brake conversion on my 56 Dodge Custom Royal and in doing so replaced the master cylinder with a dual reservoir unit. To use an original style hydraulic pressure switch meant I would have to T the switch inline someplace, which I did not want to do. As we all know those darn old pressure type switches were not that reliable. anyway, so lets do a mechanical. switch. I searched around and didn't like any of the automotive switches as they were all to large. I my quest I found a Honda Motorcycle brake light switch. Cheap and readily available (Amazon).
Fabricating a switch mount bracket was a chore. I have sketches if anyone wants to do the same.

| I'd be interested in how it mounts if you get a chance to post some pictures. I also added a mechanical switch to my 56 royal when I put a dual master cylinder on but I'm not really happy with the way I mounted it. It'll be interesting to see what you came up with. |

Location: Ponder, TX | FWIW, I had a mechanical switch and adjustable mounting bracket from a '79 Dodge Aspen that I parted out. I always look for factory Mopar parts whenever making mods in my FWL, so was pleased to find that it bolted onto my '56 Plymouth. |

Location: Invermere B.C. Canada - Rocky Mountains | Del, are you going to use a relay so that the switch only has to handle the low relay current ? |

| Good day.
1) I will try to get a pic of the brake pedal mount but in the meantime, there is a lug on the left side of the mount up at steering column height. It has a 3/16 slotted hole which works for left right adjustment.
2) this was the only option I could come up with after many days of searching.
3) the switch is capable of handling the 12v on the motorcycle without a relay so it should be AOK.
Darn technology. I don't know how to edit a photo and draw on it, so the pic is an attachment
Dave F had sent me some pics of a brake pedal mount which I am using here due to the fact that I don't have one of my own to use.
Save the fail as a PDF. Let me know if you can download the file.

Location: So. Cal | I usually just weld a small, simple plate with a threaded hole in it to mount the switch. Works well and is very easy to do, other than sticking your head up there to weld.

| In the pic above from Expert 5k, you can see the tab with a hole in it to the left of his switch. One little #10 machine screw and no weld sparks to deal with. additionally I do do have welding equipment in my shop so this was my easiest route.

Del: I use PAINT (usually bundled with the computer when you buy a new one, at least a Desk Top running windows). It is pretty easy to use.
Here is your diagram:

| Some months back there was a similar thread on the subject. Lancer Mike came up with a great adaptation of a mechanical switch that is easy, allows for future reversal to the original switch and causes no permanent changes to the vehicle. I did this conversion on my Adventurer and it was worked flawlessly. Here's a link to the thread: http://www.forwardlook.net/forums/forums/thread-view.asp?tid=42562&... Best of luck in your work!
