Car Disc Brakes Section

car disc brake pads

This is the car disc brakes section of the You Fix Cars website. On this page you'll find a general overview of how they work and some details of how long brakes last on the average automobile. Knowing the actual mileage on them can help in the diagnosis and decision making process.

Also included is a brief description of the major components involved in making them function properly. More in-depth articles about each individual component and common specific problems like noise, pulling and pulsation can be found below in the helpful articles section. Learning about how brakes work is essential for anyone who owns a car.

Even if you don't perform your own automotive repairs it is good to know more about car disc brakes. This way when you do have problems you are properly prepared to deal with them.

If you own a car for more than a couple of years chances are you will run into at least basic maintenance and replacement of the front brake pads. I can't tell you exactly how long brakes last because your mileage will vary.

I can tell you that the average replacement mileage is around 25,000 miles. Generally speaking they will last longer for highway driving and less for city or fleet driving. Either way when you take your vehicle into an auto repair shop it is very nice to be able to speak knowledgeably about the subject.

How Car Disc Brakes Work

Being an expert on the subject just might prevent unnecessary repairs such as complete system overhauls and excessive costs from life time pad replacement deals.

Disc brakes operate by using friction to slow the automobile. This friction comes from replaceable brake pads that are made of varying materials. These include semi metallic and the increasingly popular ceramic composite.

These brake pads are clamped against the rotor by a hydraulically operated caliper. Since the pads are clamped against both sides of the brake rotor both sides are machined to a smooth flat surface.

The brake rotor itself is usually separated into two surfaces with fins in the middle to help dissipate the heat that is generated by the friction. These types of rotors are called ventilated rotors and are the most common on today's automobiles.

The brake caliper is mounted to the steering knuckle to hold it securely. The standard brake caliper contains the piston and related seals and is connected to a hydraulic system. The pads are forced against the rotor by the caliper piston. Hydraulics are used to multiply the force of foot pressure.

Why They Use Disc Type Systems

Disc brakes are more resistant to heat fade during high-speed braking and repeated stops. This is because the design of the rotor exposes more surface to the air and dissipates heat much more efficiently than old-fashioned drum type systems.

How long brakes last is directly related to the heat generated and the efficiency of getting rid of it. City driving generates more heat and provides less cooling air flow therefore wearing out the brakes faster.

Disc systems are more resistant to water and problems associated with running through puddles. The rotation of the rotor throws moisture off and out of the system. The design of the hydraulic system and the clamping action makes them less likely to cause pulling conditions when the car is stopping hard. They also automatically adjust for wearing pads and require no manual adjustment.
