Customs Brake switch question 50 Merc

Discussion in 'The Hokey Ass Message Board' started by Leadsled612, Dec 14, 2010.

  1. 1950 Mercury custom brake question.Where does the brake switch go?...I have a power booster installed. I am running drum/drum w/o proportioning valve. I plumbed the front brakes already. No instructions with the unit...the original had the switch out the back of the m.cylinder. Anything I am missing? Please help.

    hydraulic switch? put a T in one of the lines and put it where ever you want, preferably close to the master and the most of the least thats my opinion......
  3. you need to put a "t" in line to screw the switch in. buy a 1/8 " pipe "t" with two flare adapters to match your brake lines.
  4. Do they sell just generic switches?

    Use a '57± Chevy truck mechanical lever switch screwed to the bottom of the floorboard.
    About $6 or so at NAPA.
    That's what I did, I bought a handfull of them for future needs.

    yeah, a couples of different types of connectors, so, just use a short brake line, get a T with your switch with flares n 2 sides and then hook it up........i have 2 different styles on 2 of my cars, one with male spades and one with male bullet can kinda chose what ya want......

    Check the Ron Francis web site. They have hydraulic and manual switches. I used the low pressure hydraulic switch in my '32.
  8. Everyone, Thanks for the info! a real help!
  9. if you use a hydraulic switch get a Weatherhead # 652X3 fitting. it has 3/16 inverted flare two ways for your brake lines and 1/8" NPT on the third port to screw in the switch
