So got the bike back after the rear shock was rebuilt. Now the front left brake seems to build up pressure and seize. The pistons on the caliper are fine. The wheel stops turning I bleed off some fluid (don't have to apply the brake) from the caliper and it works normally until I've driven for 5km then I pull over and the brake is seized. I repeat the bleeding process and fine for 5k more. You can feel the difference on the brake handle too. Normal...then rock hard as the pressure increases. Pretty sure this is the ABS pressure mod. Any ideas/fixes? I totally bled the lines on both brakes with new fluid. There is no warning light on the console.
