What You Must Know Before Buying Brake Calipers
Brake Calipers are an integral part of your braking mechanism which s extremely important for your performance of the brakes on your car. Brake Calipers can be found on each wheel separately and are used to squeeze the brake pads on the wheels in an attempt to slow the rotation of the wheel while bringing the car to a stop. Brake pads, when heated by braking processes, become sticky and can cause unnecessary wear of the rotors. This can affect the handling of the car and increase the chances of it getting a flat or a skid. Brake pads are usually made out of metal, ceramic or carbon and are heated by means of a flame from a lamp at the brake-hand brake mechanism.
Brake pads make contact with the piston and cylinder and are moved up and down by the master cylinders, which are in the cylinder area of each brake caliper. If these piston-cups are bent or damaged due to excessive wear, then they can lead to brake fade which is caused by the brake system not being able to adequately work the brakes. The master cylinder in the engine control system receives power from the batteries, which are recharged by the alternator during the braking process. Therefore, if the brake calipers get damaged either through misuse or damage, the brake system may have to be recharged, which can be extremely dangerous.
Brake pads need to be changed on a regular basis. A brake caliper is dependent upon three things; the size of the pistons, the amount of pressure and the length of time the pads have been sitting before being replaced. The size of the pistons is dependent upon the overall size and weight of the brake system, whereas the amount of pressure relates to the volume of air and gas flow required by the braking system. The length of time the pads are allowed to sit before being replaced is dependent upon the type of pads, as well as the ambient temperature and atmospheric pressure in the car. The ambient pressure and temperature can increase and decrease with the car's environmental conditions.
Brake friction is caused by two different types of brakes; magnetic and floating. Magnetic brakes create friction by attracting and repelling. The main advantage to this is that it offers very low friction, while at the same time, the friction is uniform all throughout the braking system. The floating type of braking system uses bolts to connect the piston to the caliper. There is no friction, but the overall effect is more of a loosening of the bolts, rather than a tightening one.
As time goes by, the design of most car engines has changed from the original design, and they now rely on rotors to help reduce brake friction. Brake pads, as we know, are made of rubber and they wear out over time, which makes them less effective and even destroys the material if not replaced quickly. Rotors wear out due to the sheer force of the brake calipers working against each other, as well as road debris and heat.
Brake pads should be inspected regularly to ensure that they are in proper working order. The rotors should be cleaned thoroughly at least once a year to remove any dirt and dust. It is important that the entire brake system is cleaned at the same time to ensure that there are no dirt layers within the brake system. Road debris and heat can cause huge damage to brake calipers. This should be taken care of by the owner as soon as possible, so that it does not have an adverse affect on safety.
Brake discs are made from steel or aluminum. Both have their own advantages, but the steel type is generally preferred by drivers. The main advantage is that they are more durable and do not break easily. However, they are heavier, so drivers must be extra careful when driving on slippery roads. The aluminum type weigh slightly less, making them easier to handle. They are also more resistant to corrosion than steel brake calipers, but this disadvantage is offset by the increased cost, which can be up to $50.
Brake pads and discs can be replaced using either hydraulic or fixed calipers. In general, the former is preferred due to better reliability, however, some drivers may find fixed calipers to be more suited to their driving needs. Whichever type of brake system is used, it is important that owners pay close attention to the amount of force that is exerted on the brake pedals, as excessive pressure can cause damage to the pads and the pistons.
