1965 Mustang Brake Switch Question

1854 Views 6 Replies 5 Participants Last post by  printman
We are trying to put a brake switch on an automatic brake pedal on a 1965 Mustang. Our pedal stud has a round clip instead of a cotter pin. What year is this brake pedal and what brake switch do I use on the brake pedal? Does this brake pedal require a switch on the cylinder? Our new brake switch that we ordered is too wide for the stud. Thank you.

Early 1965 ( 64.5) had the Pressure switch on the Master cylinder under the hood. Like this one. If you replace it be sure and buy the "LOW" pressure type which is available from most auto stores.

Later 65's had a mechanical switch on the brake pedal like this one:

And must be installed correctly;

Here is a diagram of switch

Hope this helps.

I think what has happened is that we put a different brake pedal on and now the correct switch (the one in your second picture) won't fit because the stud is too short and there's no place to insert the hairpin as in the diagram above. Do you have any ideas on how to fix this without replacing the pedal?

The best thing to do is find a park at the junk yard or YOU PULL yards and replace the pedal.

One thing you may want to try is to "squeeze" the brake switch where the two holes are that the stud goes in, but I doubt if you will gain over a 1/32 to 1/16 on an inch. And this may damage your switch where it will not work, but only cost less than $10.00.

Good Luck

Where is the switch connector? And what does it look like? Is it factory or has it been messed with?
Check at the base of the post the switch and pushrod slides on to make sure an extra nylon or metal washer is not stuck around the base. Does your post have a groove for a circlip or e-clip?
Had the same issue with the short stud not allowing the switch to connect properly when I went to disk brakes on my early (64 1/2) coupe.
Save yourself a ton of headache and just change it out to a 65 pedal (bigger stud), trust me it's not that big a job and well worth it.
