Hi All My 1929 Model A Sport Coupe had juice brakes fitted before I bought it and I'm now trying to rectify a few issues around the stop lights and handbrake/emergency brake. Firstly, can anyone identify the master cylinder as I think the stop light switch is toast. Secondly, the emergency brake is a lash up (being kind) I wonder what everyone else does with the emergency brake setup when going from rod to juice brakes, better than what I have I'd guess and hold the rust Thanks in advance.

SL switch is is just a standard 1/8 pipe thread item ,MC has no bearing on what switch is needed. But as said MC looks to be 40s Ford . The emg cable system is/was what most people did when still using the stock lever and cross shaft. It would be nice to put some sort of adjustment one at least one side cable so both brakes would work together, turnbuckle?
Put a brake light switch on the pedal. The brake fluid switches fail often and can cause a fire when they do. If you keep using one, make sure the circuit is has a fuse in it.
Cause a fire?,,honestly I have never heard that one before. I have used them for years,a new one is relativity inexpensive and the 40 Ford master cylinder can be rebuilt. HRP
google ford cruise control switch fires , I would have lost my house to one , if I didn't have a car in the garage and one in the drive that night . the diaphram ruptures and ignites the brake fluid , they rectified the problem with a new switch with a fuse in the link , I fixed it by using the recall kit and a relay thats only hot with the key on .
Thats a little different than a vintage ford brake light switch. FYI on most, no new switch was installed on the modern recall. It was literally a jumper harness with a fuse between the original harness and switch. I used to go down the row of cars waiting for service. Grab a bunch harnesses, walk the line, write down the vin of any I did. Easy money. Posted using the Full Custom H.A.M.B. App!
well then your dealer didn't follow the recall instructions as the switch if it was red was to be removed and replaced with kit #1L1Z9F924AA , I have the Bag from the recall still from my explorer which had the red switch which looks like this the new switch is like this I got a letter for my lincoln 2 weeks after it burned to the ground
They got the jumper wire regardless of switch color. Red ones went into the shop. There weren't alot of them compared to the rest. Posted using the Full Custom H.A.M.B. App!
Switch is a different design internally. Were talking about something installed on literally every Ford vehicle from 1940 till at least the late 60's. If there was some huge known problem with them, it would be do***ented heavily....so far I am not seeing much evidence out there. But I do agree...its not exactly the most awesome design. Sorry about your car too. Never actually talked to anyone that had one go. Posted using the Full Custom H.A.M.B. App!
My '31 RDPU had a master cylinder mounted on the firewall but I decided there was too much flex in the firewall so I changed it. Does yours flex? Your backing plates for the brakes are 1939 to about 1942 (pre war). The post war brakes did not adjust at the bottom. Note that many of the pre and post war brake parts do not interchange so be sure to get the right ones. Charlie Stephens
Hi Charlie Here's my firewall/pedal box, no flex, looks a reasonable job. Regards Kevin [QUOTE=Charlie Stephens My '31 RDPU had a master cylinder mounted on the firewall but I decided there was too much flex in the firewall so I changed it. Does yours flex?
Kevin, Yours looks good. They added enough metal to take the load out over a large area. I wish mine had been done that well. Charlie Stephens
basically the switch was used from the 1920 up on alot of vehicles and imports , my 50 pontiac had one it showed signs of weeping , I had one on a 62 MBG that caused me to have fits till I changed to a modern pedal type switch no its not a good design but practical at the time , as for the Blackwood ( lincoln) , it was a loss . but thats what insurance is for they replaced it with a new vehicle ( excursion) of the same cost as the truck was a one year only . like I said it could have been worse and been the garage and house . and several people have lost there homes .
