purchased a 04 ST 1300, after buying it the rear abs locks up same day I got it. Removed the rear caliper and pads to clean it up and put back together. notice front right fork area delay valve leaking now when pushing only rear brakes. internal cap looks to be missing on delay valve, so I ordered a complete rear caliper set with pads, and delay valve. After clearing the rear piston and only using front brakes the bike works on freeway without rear locking up as it did before. I return back to my friends house the bike moves in neutral, I can walk it around just fine, then I shut off then came back a few minutes later to start the bike back up, the abs automatically locks up the rear solid again, I have to go to 1st to drive it to free it a bit but its extremely difficult to move. Any help is appreciated.
