Car brakes how good are yours?
Are you hearing a nasty screech when you press the car brakes pedal in your car? Does it sound like rock monsters are playing the world’s loudest frame of bowling every time you need to slow down? Well, it may be time to change your car brakes. Here’s how. A car’s braking system is one of the most important components in your driving experience, as it’s the only thing keeping you from smashing into that bus full of nuns on your spirited run to the grocery store. It’s a fairly simple hydraulic system that allows the force applied at the pedal to be translated to clamping force at the wheel. Here’s how it works: When a brake pad wears down on a rotor, it will often make a squeaking sound when applied. This is an audible safety measure to make sure that the driver knows to change the brakes soon. Unfortunately, some pads don’t do this particularly well, so newer cars have brake pad wear sensors installed as part of their system, alerting the driver on the dash that the pads needs replacement. In addition, when a brake pad gets low, it will require a longer stroke of the caliper’s piston to clamp down on the rotor, therefore lowering the amount of fluid in your brake reservoir. If the pads are low, you’ll be able to see a noticeable change in your brakes fluid level, and may even get a “BRAKE” warning light on the instrument cluster. If all these signs are ignored, the pad’s material will wear down to the point where the only thing making contact with the rotor surface is the pad’s metal backing plate, which is made of steel, and it will make heavy grooves in your rotor’s surface, forcing you to replace the rotors as well. Check your car brakes always and make sure they are in good condition.
