2003 Sx2.0

Ive got a 2003 SX2.0 and i think that there is something wrong with the brakes because every time i touch the brake pedal the car feels as though it is hitting a series of rather large speedbumps. Ive taken the car in 2 or 3 times and the mechanic insists that the brakes are fine. Is the mechanic wrong or could it be something else?

Thanks

Air in the system,do you feel a palsating. if you do, its the rotor. it has high/low spots in it. master cilinder!?what state do you live in? National trie and batt. do my brakes here on Ohio. they are pritty good

actually i dont live in the states i live in canada, toronto The dealer usually does all of our brake work but they have been saying that everything is fine. Con artists

your brake rotors might be warped
