It felt worse immediately after the change. Today it felt a little better I would say. I still have a strong feeling the bleeding was not done correctly.The pedal should feel solid from the get-go. If you have to pump the pedal a few times to get a solid feel then there is still air in the lines. Did they bleed the brakes a second time? I'm assuming you're saying that it feels worse now than before the caliper change.
I will drive for a day and see - If I measure the moisture and it is a high number - that should give me a hint? shouldn't it?
