People often wonder when is the right time to get our brakes fixed. If they wait too long can they can ruin the rotors or other vital mechanical parts, and people worry if they do it to soon that they are not getting there money’s worth for what they paid when they got there brakes done last time. There can be multiple causes to what can cause brakes to squeal as you will read below. At Toyota of Danville brake repair is taken very seriously and every effort is made to make sure that the problem is fixed the 1st time.
Worn Pads
A brake pad is comprised of steel backing with friction material attached to it. Application of the brakes produces hydraulic pressure that causes the brake pads (via brake calipers) to clamp down on the rotors (discs) creating friction. It is the friction of the pads against the rotors that slows and stops the vehicle. When the friction material on the pads wears down, it is time to change the pads. Some pads are equipped with a wear indicator, which is a small spring steel clip. When a pad is worn, this clip makes contact with the rotor and generates a high-pitched squeal, telling you that it is time to service the brakes. If the pad does not have a wear indicator, then when the pad has worn down to the steel backing it will grind into the rotor and need to be replaced. In this scenario, the rotor may have to be replaced as well, depending on how badly it was affected.
Pads and Rotors
Brake squeal can also occur when brake calipers stick and the brake stays partially applied. When this happens the pad is in constant contact with the rotor, producing excessive friction and thus heat. Overheated pads harden and crystallize. This glazing occurs on the rotors as well. The squealing sound is a result of these super hardened surfaces coming in contact with one another. Remember, it is the friction created by the brake pad against the rotor that stops a vehicle. When crystallization of pad and rotor occurs, there is much less friction. This results in diminished braking power and squealing brakes. At this point the pads must be replaced and the rotors resurfaced or replaced.
Brakes are one of the most important safety features that a person will have on there vehicle. So making sure that they are always in great working condition does take some thought. Taking it to Toyota of Danville insures that you will be getting the best quality that is available.
