Walking in an auto repair shop because you need an estimate on how much it would cost to service the front brakes of your vehicle is simple right? Afterall, they are only 'brakes'.
What most folks do not realize is that it's a braking system, meaning a combination of parts working simultaneously in sync to bring your car to a stop. It is a system of brake fluid, hoses, calipers, master cylinder or booster, brake pads, brake rotors or drums, wheel cylinders. Now all those items does not make it sound like it's only 'brakes'.
Keeping healthy brakes in your car begins with keeping your brake fluid clean and free of moisture. The fluid needs to be replaced every two years or 24,000 miles as recommended. The fluid runs through what is called brake lines. Sometimes, air might exist in the lines. The system is a sealed system and if air is present in the lines, there is cause for concern. Another part that you need to be aware of are front disc brake pads. These pads typically have what is called 'wear indicators' which are like metal tabs that rub on the brake rotors making a distinct squeaking or squealing sound when trying to stop the car. These wear indicators are there to alert you before you consume all the pads. The pads are attached to a metal backing, consuming all the pads will cause you to go metal to metal (metal pad backing to the brake rotors made of metal), often hear grinding noise and would cause excess heat on the brake parts. Metal to metal means damage is being done period. Cost of repair start going up up up. If you could not afford brake pad replacement, you would not be able to afford anything else that go bad if you choose to ignore the needed service. I mean, what are you going to do when your car does not stop? How much do you think it will cost you if you hit something or someone? Now brake pad replacement does not sound like too much now does it.
Keeping up with brake inspections after 20,000 to 40,000 miles between front brake pad replacement will save you money in the long run by keeping your brake system clean and functioning at it's best. Pricing a brake job really depends on how much or how little damage has been done and how soon you react to the signs that your brakes need some attention.
Hope this contribution helps.
