I have a 2007 Honda Civic. I had its front brake pads replaced 2 months ago and had the rotors replaced. Now (and perhaps before--I can't recall) whenever I'm braking and hit a bump, the brakes lose their grip on the rotors and I no longer can slow down. I have to press the brakes much harder in order to stop. What could be going on and how can I fix this? It is especially terrifying coming off a freeway and hitting minor bumps where the road changes from concrete to asphalt.

(My brake job is guaranteed through Midas, so I shouldn't have to worry about the possibility that it was done wrong. If I recall correctly I requested ceramic brake pads. Also, multiple sources tell me that the rear brake pads are fine--though I haven't looked at that myself.)

Update: Took it to Midas, the master cylinder is going out.
