font tire make a whisting sound when turning left Check the front brake pads, it may be the brake warning "squealer" letting you know the brake pads are worn down.
If you are talking about the brake pad wear sensor also known as "squealer", most replacement brake pads come with the "squealer" attached. So it would depend if the mechanic installed pads with the sensor or not.
They are shaped to fit tight against back of the pad.
Brake pads are worn and the squealer tab is rubbing on the rotor. Pads will need replaced.
Some brake pads have a 'squealer' plate attached. This thin plate does not do anything until the pads become badly worn. Then the plate rubs against the rotor, squealing (emitting a high pitched singing noise) letting you know you need to replace the pads - before they damage the rotors. Without this feature, pads wear out then grind deep grooves in the rotors that then have to be resurfaced (ground smooth again if there is enough metal left) or replaced. So getting pads with this feature saves you from having to replace a set of expensive brake rotors.
That would be the brake "squealer" making that noise. It's telling you the brakes pads are worn down and in need of attention.
They are not supposed to make noise unless abs is on. If you are talking about the squealer tabs on the pads, they will some times squeak when you are off the brake and go silent when you brake.
Brake bads need to be replaced based on wear and not on mileage or age. Most brake pads will include a "squealer" or indicator that will make a high pitched squeaking noise as your breaks reach the end of their useful life. Most break shops will also be able to measure the remaining life on you brake pads and will often do so free of charge.
Usually because of wear, a disk brake system typically has a squealer that with contact with the rotor will make a squeaking sound telling you its time to change the brakes..some have no squealer and the sound is coming form the rivets on the pads making contact with the rotor..ie past time to change..If the brake pads have been changed or are in fine shape and there is a squeak it is because there is no anti squeal compound on the back side of the pads.
If you want to know if there is somewhere you can get instruction on changing brake pads because you need your brake pads changed, then the answer would be yes.
Alot of cars have whats called a squealer on the front brakes . . . it makes the brakes squeal when you use them. . . if it doesn't then a good indicator is grinding cause that's telling you that the brake pads have wore down to nothing.
Brake pads are part of the cars disk brakes. There are four different brake pads they are semi-metallic brake pads, organic brake pads, low-metallic NAO brake pads and ceramic brake pads.
