Yes. Brakes can make noise even when you are not applying actual braking force. Some examples of this include foreign objects that have been lodged in between the caliper and the rotor. This can be something as small as a pebble that is lodged between the two or something more serious.
In addition I have seen calipers with the piston falling out of them due to neglect. this is not only dangerous it is quite loud. In either case you should have the wheels removed and the brakes inspected for possible damage or foreign objects.
A common reason is that the front rotors have warped. Go check out WikiAnswers on the topic of "warped brake rotors". Rotors should wear out smoothly in normal driving. Use of the brakes that generate lots of heat (hard braking, riding the brakes) will result in warped rotors.
There will be a pulsating on braking.
For the brakes, check for warped rotors. For the turning, check for worn CV joints.
If you only did the front brakes, the problem may be in the rear brakes.
You need to check your brakes and rotors. Typically when the rotors go out it will make any car/ truck do that.
Were the rotors resurfaced or replaced, or just the pads? Warped rotors are the most common cause of vibration when braking
Either the rotors have deposits, or the ABS is kicking in. Either is evidence of aggressive braking.
I could be your rotors are need to be reground. Let your brake man check out your brakes.
This is probably due to worn brake rotors on the brakes, if there is no vibration when driving then this will be the cause.
Most IS 250s, depending on driving, get about 25000-30000 miles on the front brakes and rotors.
the brake rotors are warped. resurface or replace rotors. if the vehicle shakes without applying the brakes, check tire balance.
You can tell if a Lincoln needs a new rotors by the braking fashion of the car. When applying the foot to the brakes, if the pedal tends to vibrate, the rotors could be deteriorating.
