Mechanic Recommendations in Kitchener?

Hey guys,

So out of the blue my car brakes are not working as well as before. The pedal is softer and can be pushed all the way down. I can still brake somewhat but it takes a little more time to stop the car now. This all happened out of a sudden. The brakes were perfect in the morning, but they just weren't right in the afternoon.

Anyway, I took it to Kieswetter in Kitchener. They inspected the brakes and decided that the car needs a new Master cylinder. They quoted me $300 for the part + $340 for their time + tax! Besides the costly quote I am still not fully convinced that a new cylinder is needed. Hell they didn't seem confident themselves! And wouldn't you just hate it to pay this much for a part only to later discover it wasn't the problem? :) Not saying that they are wrong, but I would like a second opinion.

Any recommendations for a good and inexpensive mechanic in the Kitchener area?

Thanks guys!

Forgot to mention, the car is an 07 Mazda 3 GT (manual) :)

Is the brake fluid low?
