APG Big Brake Kit Issue

[Ken951]

Need some help. I have a 2022 Supra and I am installing the APG BBK all around. We are having an issue with the rear electronic parking brake not fully disengaging from the calipers which doesn’t allow the car to roll freely. Does anyone have any advice? Thank you.

The OEM rear brake caliper/parking brake? If so remove the 2 Allen heads holding the motor to the caliper then stick I think a 5 or 6mm Allen in there and pull the piston back all the way.

This may sound incredibly stupid, but I've found I run into far less issues when I put it in diagnostic mode, before I do anything. That a possibility? When I replaced rear pads/rotors, I had zero issues with the electronic parking brake, that a lot of people have.

No it’s a full aftermarket replacement with calipers and rotors on all four corners.

Welcome to the club! Are you going to be tracking yours? As in the reason for the change

Figures. I know I use my ebrake every single time I park. Lately I feel like it has been sticking a bit when I try to take off. I feel it grab and makes a shit noise, but only for a brief second. I hope you can get it figured man.
