Just rebuilt the entire braking system on my 66 Fast back. I installed a Wilwood M/C with a Proportioning valve, the valve comes with a brake pressure sensor. Instead of replacing the dreaded brake pedal switch I wired the brakes to the brake pressure sensor on the Proportioning valve. I am not real happy with the sensor because I like the brake lights to come on immediately and this sensor takes 60 psi before the sensor reacts. Thoughts on future problems because i bypassed the almost impossible to put on brake pedal switch?

meh. The TPMS are not worth the $ to replace on my 350Z - so I keep a tire gauge handy and check them...
So just keep an eye on brake fluid... ;)

Confused...how is replacing the brake light switch almost impossible? It takes like 5 minutes...10 if you remove the drivers seat.

Patrick’s pretty quick with seat removal and installation.

He pulls the seats, both, every time he gets new wiper blades,.....

I can do it - but because I removed/installed/removed/installed the switch... ;)

Word of advice...remove the seat. It’s four nuts.
Word of advice...put three layers of black electrical tape at the base of the switch between the tangs. Trim any excess out from around the tangs. Works every time.

Replace that "brake pressure sensor" with a '64.5 Mustang brake light pressure switch.

Why is this better? I could not find the psi. The one I have is 60-100psi and I am assuming if I get one that is lower pressure it will engage the lights earlier when I depress the pedal, Am I correct?

yep. the original factory switch is set too high pressure wise, lower pressure means the lights come on sooner.

The Ford hydraulic brake pressure switch has a very low PSI closure setting. All you have to do is to touch the brake pedal and the lights come on.
