Brake switch conversion.

Hi,
Just wondering if anyone has removed their hydraulic brake switch and gone to a mechanical type switch? My hydraulic switch is sticking. From what I have noticed, mine seems to be heat related. It sticks on after travelling a reasonable distance and the returns to normal as the temperature in the engine bay decreases. Any pictures would be appreciated.
Thank you, Robin.

It's no wonder I was having problems with my brake switch. My 50 year old switch had definitely seen better days (see picture). The terminals were loose, as well as the sticking contacts. I have installed a new hydraulic switch , so time will tell if it's fixed.

Hi Robin,
I would say a switch that lasted 50 years must be a record for longevity
Just curious if during that time you were using silicone brake fluid or not. There is a school of thought out there that the diaphram in these switches deteriorates when silicon fluid is used. Others disagree. And what may have been true in the past may not be true today if they are made differently. I for one have gone to synthetic (not silicone) Dot 3 & 4 brake fluid in recent years since I replaced my switch and some other rubber brake components and have been pleased so far.
Cheers, Gene

Hi Gene,
I have also heard around the traps that very same thing regarding silicon style brake fluids. I have even heard of brand new switches failing prematurely. The last time I replaced the brake fluid, I replaced it with a Dot 5.1 which is compatible with Dot 3 & 4 fluids. I used the AP racing Dot 5.1 which is a non-silicon based fluid. My brake lines have also been upgraded.
Regards, Robin.
