The front bearings may be bad if that's where the sound is coming from.

The brakes on my 2004 Concorde come on while driving down the road. The brake pedal comes all the way to the top and is hard to push. The brakes stay on and will bring me to a stop by letting off the...

The problem is most likely in the vacuum booster. It has a valve inside when slight pressure is applied to the pedal, applies vacuum boost to the master cylinder aiding the operator in braking. If you notice applying the brakes several times with the engine off, the pedal will harden in the same fashion. With a malfunctioning internal valve the booster can apply the vacuum boost when not needed.

there really is no easy answer for this because of many factors that may affect brake component longenvity.

brake friction material type
stop and go traffic
hard stops
freeway driving
road conditions
dusty driving conditions

expect 25K to 50K and beyond

Hard driving can lower the mileage below 25K miles

Humm in car

Try moving the tire to a different position and see if the sound stays with the tire or stays in the right front. Does it do it when braking, accelerating, driving straight all the time? Also - if you get on a long straight stretch of road with no traffic - switch it to neutral and turn the engine off - REMEMBER - you will lose power steering and brakes with the engine off.

With the sudden loss in brake pressure, and the light on, I would check the fluid level and if its low, suspect a brake fluid leak, that may be the burning smell, maybe leaking near a exhaust pipe? You dont mention where you are, but if its NORTH and salt is used to get snow off the roads, brake line failures are real common.

Weak humm when driving over 35kmh.

possibly a wheel bearing or tyre noise from badly worn tyres
while driving in a straight line and noise is present change lanes or shimmy car left and right if noise gets worse or better wheel bearing problem
also if noise gets worse in normal town driving speed and gets less at higher freeway speeds check your wheel bearings

Have you checked at the throttle linkage to make sure that all is ok? I have seen this problem, it is only a plastic clip that holds the throttle linkage in place and they brake and then no throttle.
