Thumping in brake after service

Last week I posted about a squeek from the front brakes. Local Big-O
tire shop replaced pads and turned one rotor, replaced one rotor, also
flushed brake system. (105,000 miles on the car).
It was fine on the way home, but last evening I took the car out
(first time after service) and heard AND felt a thumping at slow speed
when the brake pedal is applied. It almost sounds like it is in time
with the wheel rotation. We put the car back in the garage.
Due to my schedule, I can't get it back to them for a day or so. (2nd
car, usually garaged till weekends).
Anyone have any ideas as to what could have gone wrong? It definitely
sounds like it's coming from the right front (the one that had the
problem). 1997 Dodge Caravan ES
Thanks in advance.
PS
I have been using this shop for some time for all my service and have
had no problems in the past with the quality of repairs.

loose bolts for the braket where the caliper sits. it might happen. or
pad springs or even loose or inporperly tighted nuts.
