Question:

Brake pads????

Ok someone correct me if I am wrong. I assume that this is the way brakes are made upyou have the pads, which are cheapand ‘underneath them you have the rotors, calipers, etc. Why not just frequently replace your brake PADS, that way they would never grind down far enough to where you would have to replace the more expensive componants of your brakes. As in, replace your pads every 6 months.before they grind away and into the major components of your brakes. This would save everyone a lot of money correct?

Answer:

the shape of the pads can be changed by simple road anomolies like dirt and gravel. Your rotors will adjust to this shape eventually, but the best thing is to replace your pads when needed and have your rotors turned at the same time. This will ensure the best use of your brakes, which is vital to the safe operation of your vehicle. Replacing your pads every 6 months is a bit excessive, brakes can last a few years if you don't abuse your vehicle.
No brake pads are made with a metal composion in them ie semi metalic brake pads Metal to metal will wear down the rotors even if you replace them every 6mths. Also there is a lot of heat that is generated when you apply your brakes which is why rotors warp and calipers frezze up And even if you did replace your pads every 6 mths, you will still need to have the rotors trued up or the new pads you just installed probally won't last 6 months
Not a bad theory, but you overlooked a couple of things. It takes two surfaces to create friction, and in a braking system, it takes something to bring those two surfaces together. Friction creates heat, which can have an adverse effect on braking surfaces. Pads are made of a softer material than rotors, and tend to wear out faster, but rotors also have material taken away with each braking. Also,the heat generated by braking can warp rotors, not unlike a CD left in the sun. The piston in a brake caliper has to push and pull the pads toward and away from the contact surface of the rotor. As with anything that moves, wear and tear is inevitable. If you only replace the pads when they are worn, or every 6 months, you are not looking at the whole picture. As far as underneath is concerned, all braking systems are just that: systems. Without all braking components working together, and within specs(BTW this includes tires, which actually stop the vehicle), your vehicle is potentially dangerous to you and everyone else on the road. Have your vehicle inspected by a qualified technician and ask questions.
