I took it a step further, and am happy with the results, was able to drop the peddle pad about an inch. Used a 1/4 in. 20 TPI bolt and lock nut and hand tools. Can adjust it now with a 1/2 in. and 10mm wrench.......
2015 K1600GTL - After having the Suburban Machinery foot peg lowering kit installed, I needed to resolve the usual shifter and brake pedal issues that result. For the shifter, I had Ilium Works' shifter extender installed. For the brake pedal, I had Ilium's replacement brake pedal installed.
I didn't like the brake pedal-foot interaction so I tried adjusting the brake pedal and in the process the rear master cylinder push rod came out of the rubber boot. I put everything back together and did not find a way to get the pushrod to connect to anything up inside the rubber boot. The rear brake is working, but I'm not convinced it's going to fail shortly.
So the question is: Is there some kind of connection to be made with the push rod, or is it just centered inside the boot (as I have done) and that's all there is to do?
