I have a 1999 Ford Contour. I replaced the rotors, pads, drums, shoes, and the brake fluid valves. This vibration did not occur before the brake work was done. The mechanic is saying this is more related to the tires, not the brake sytem. I am not convinced.

Tires do not vibrate only when hitting the brakes. This is due to a rotor that is warped. To fix this problem on my car, I took a sanding disc and cleaned the hub assembly, machined the rotors, and torqued the wheels. Any one of these or a combination of these may be causing your condition. I would take it back and have the mechanic do the above.
On the other hand, tires that are out of balance will vibrate at speeds over 35mph. Tires that are bad such as having a bad cord will vibrate all the time, not just when braking.
FOR THE RECORD:
Rotors do not have to be factory defect. They could be in perfect condition when they leave the factory but doing something as simple as placing them on their edge can cause them to warp.

He may be right. However, you may want to have the mechanic take another look at the rotors that were replaced. Sometimes, not often, rotors come out of the box defective. It's called warpage. Essentially, the rotors are out of round. It sounds like that is the problem if the steering wheel vibrates when you brake. It should all still be under warranty. Good luck!

Your mechanic is full of donkey snot. Its not the tires. It could be your anti-lock brakes are malfunctioning -OR- your car is afraid of excessive speeds greater than 20 miles per hour.
I would insist he go back over his work. If the anti-lock breaking system is malfunctioning it could be very dangerous. And don't be shy about it. Just tell him something is very wrong and he has to look into it.
If you get any static or he charges you for doing any extra work - turn him into the Better Business Bureau. Also some television stations have a program where they go to bat for the little guy and give the business owner bad press unless he or she makes good with his or her customer.
Never underestimate the power of the media.

Your mechanic is full of crap. The vibration is most likely being caused by the front rotors he put on the car, they are warped and either need to be resurfaced or replaced.

Generaly, that indicate a warped, or cracked rotor.
In this case, I'm at a loss. Did you possibly get some debris between the rotor and spindle? Causing an out of "true" condition?

1. the tires are out of ballance
2. the pads are grabbing the rotors
3. belive it or not after the tire have been remounted on the car the lug nuts were not tourqed down fords are famous for this read your manual it will be in there

the tires doesnt sound like its your problem.did he spray the brakes after he installed them to get the dirt and grease off them.also if he doesnt know what hes doing,he might have got the rear brakes on backwards.did he check the calipers,maybe 1 of them is hanging up.

It is possible your ABS (antilock system) is malfunctioning,,,usualy because of air remaining in the brake lines.
your tires would have to be damn near square to cause a vibration at low speed.

warped rotors, I've seen them brand new right out of the box put on a car and be warped.

both a bad tire and a wharped rotor or drum can do this.
