Volks,
Just got back from my FLATS.  Had new metal valve stems put in so I could crank the pressure on my Mich MXTs up to 50 lbs.  While they were at it I asked them to look at the brakes to see the condition of the linings.  When I picked it up yesterday.  First time I hit the brakes it made a "wacka-wacka" noise and I could feel the same pulsing in the pedal.  I took it back today to complain and have them fix it.  Come to find out they "heated it up" (I assume meaning the drum) to get it off to look at the brakes.  Today they turned the drums (no charge) but said they'd replace it if was still causing a problem.  I just drove it now and really can't detect either the pulsing or the noise.  Should I be concerned about this and make them pony up for the new drum or just be happy they got rid of it?  Is there any long term concerns?
TIA
