Stop light switch adjustment

[Jim69coronet]

I just finished installing a bendix booster and linkage. Yes.... the pedal is lower but may not be a problem. The pedal is even with the accelerator pedal and the bottom edge is 4 inches off the floor. My problem is the stop light switch is about 1/2 inch from the brake pedal. There doesn't appear to be enough adjustment to close the gap. It looks like there may be a "slot" in the bracket for making adjustments but not sure. Maybe I can elongate the slot? Are there other options? The m/c is not installed if that makes any difference. Thanks.

4" is kind of low, I asked the same question a while back 7"-7.5" seemed to be the norm. You should get the pedal height corrected before reworking the switch.

I'm using a Dr Diff's kit. How do I raise the pedal height?

Usually lengthen the push rod for the Master or booster.

I’m not familiar with Dr Diff’s kit, you might have to source an adjustable pushrod.

I recently fitted a Dr Diff kit, Bendix style booster and linkage. I had to lengthen the linkage pushrod by 1/4" to bring the pedal up. I just cut it in half and welded a 1/4" length of rod in the middle. This will lift the pedal up to just the right height, not too high that you have to take your heel off the floor but a lot higher than it was. Removing and refitting the pushrod is not an easy job once the linkage is installed but it is possible. Once done the brake light switch can be adjusted to work without any further modifications.

This is where my pedal ended up. I get a full pushrod stroke and the pedal doesn't hit the floor, close
though. I'm going to leave it as is for now. Way back when I had a new 1969 Sport Satellite and remember the brake pedal being like this or close to it.

Classic Industries has a good selection of hardware you can use to lengthen your pushrod. I spent like 100 bucks putting together a combo of things and after I was finished, I saw they had what I needed for cheaper. (Oh well)
