My 2017 has a linked braking system , not ABS. After about a year after getting it [ new] I had the left front brake caliper fail to release completely and it turned the rotor very dark. The caliper and rotor were replaced under warranty, so last summer the replaced caliper did it again. So, this time I removed the caliper and pumped the brakes to make the pistons move out and cleaned the caliper and pistons with brake clean then reinstalled, then the right caliper did it while riding the Blue Ridge Parkway, so in a parking lot I removed the caliper and cleaned again. Well it happened last weekend again, now keep in mind I have always had the brake fluid replaced as required and it is always the front calipers and never the rear. The front calipers are 6 piston calipers so finding aftermarket calipers are out of the question because no one makes a caliper with two hoses except for HD [Brembo]. So I have just a few options, 1 replace with factory calipers which I don't think will help 2 replacing with Performance Machine 4 piston calipers and making the front and rear systems separate. 3 replace front brake line assembly hoping that will fix the issue. I have my doubts that it is the hose assemblies since it has happened to both front calipers at different times. I am just stumped by this.
