Does this help?

Button Panel

Does anyone have the wiring diagram for the button panel surround

Oh, my package might very well come with that same paper. That would help very much. Thanks.

How does one determine a sticking caliper from a sticking pedal?

I had a drive recently when I got home the drivers rear caliper smelled real hot and barely let me pull the car into the driveway. I pulled up on the pedal and then I was able to pull into the driveway. Now the car has always kinda had a hangup, but that comes back to my question above.

If it's the pedal, binding or misalignment on the rod between the pedal and the brake booster would be a good place to start. Or your brake booster could have a diaphragm issue with the internal spring is not pushing back enough. Might need a spring on the pedal to pull it back all the way, some have added this when experiencing a similar issue.

There’s also a foam “spacer” on the booster to brake pedal. If it’s on the wrong side, it can bind.

also check the alignment of that caliper to the rotor. some have had to add a washer on the adaptor to center it properly.

Ive got 500+miles on this car already, I feel if if it was a build quality issue, it would've presented itself already. But I will check.

What should the pedal foam assembly look like? The order, not its physical shape. I know its there. Im just not out there at the moment.

It has nothing to do with build quality. It has everything to do with its still a new build and something could be slightly off or settling in. I would check to make sure the booster rod is in alignment with the pedal stud. I would also make sure the pedal pivot/mount area is free and lubed if possible. Then I would go to the rear calipers and see if they are properly centered on the rotors and make sure everything is tight.

the setup for the pedal from right to left is pedal, booster shaft, foam spacer, then retaining clip.

Almost positive mines and oval nut, not a clip. Wonder if its too tight or if there is room for adjustment.



Revision G is here.
22-23 PSI is the target and overboost issue has been adjusted.
