(AOL Autos)-- Your car is loaded with some very valuable goods. Let\'s talk about a major safety aspect of your car, the braking system. The braking system on most people\'s cars is not noticed because it is \"invisible, invisible \". \"That is, until there is a problem, the well-known grinding usually occurs when you step on the brake pedal. What is the most common sign of brake failure? Poor braking performance ,( Difficult to park) When the brake pulls to one side, it makes a scream or grinding noise, or the brake pedal of the brake pedal during the braking process \"grabs\" the loss, and clicks when the braking excessive resistance during the acceleration process ( \"Anchor walking\" syndrome) The ABS light of the anti-lock brake is on, let\'s look at these warning signs in more detail. The reasons for poor braking performance are as follows: 1. Crystal brake pads and/or brake hoofs: the brakes harden due to heat and no longer effectively grab and stop the rotation of the brake drum or rotor. This usually happens after the brake is over-used, either because of the over-panic stop or because of \"stepping on the brake \". \"The brake material must be soft enough to wear and hold the drum or rotor to stop the car. Overheating will harden the brake material so that the brake fails. 2. The brake will be affected by oil stains or oil stains. Oil from the rear differential or the front cross shaft can be brake from the oil seal that may be faulty. Grease on failed rubber boots on front end components ( (Such as ball joints or tie rods) I can find a way to brake and also cause this symptom. 3. Power brake booster loss of power assist is another reason for poor braking performance. This may be due to the loss of the engine vacuum or the deterioration of the vacuum brake booster diaphragm. 4. The \"hot spot\" on the brake drum or rotor is the hardening point in the drum or rotor metal structure formed by the overheating of the brake. They resist natural wear of friction materials ( Brake pads and shoes) This must occur during the braking process, thus causing a loss of braking power. There\'s nothing to catch on mats and shoes. Screaming or grinding noise from the brakes: this is usually a sign of wear or glaze of the brake pads. The squeaky noise comes from the wear indicator, which is in contact with the brake rotor when the brake pads are worn to the point where replacement is required. The design tells you it\'s time to check the brakes. Unfortunately, most people wait until they hear the grinding sound, which means that the brake is grounded through the wear indicator and the rotor. Check the brakes if you hear the scream! Waiting for grinding noise will cost you money! There is no wear indicator on the rear brake. Check every six months or when the tire turns. Not when you hear the grind! Delays can have economic consequences. Pull or grab to one side: this can happen for multiple reasons. Poor brake adjustment, freezing brake, leakage of brake fluid, leakage of oil/grease on frozen emergency brake cable or brake shoe or brake pad may cause pulling. Loss of brake pedal: This situation is usually due to brake fluid leakage caused by brake hose or rusty metal brake line, worn wheel cylinder or brake caliper failure, or worn main cylinder. A simple \"end\" of the system will reveal what is happening. The pulse of the brake pedal: the reason for this is very simple, that is, heat and wear. The heat and mechanical wear of the brake rotor or drum can cause warping. This distortion is transformed into a pulse ( Motion up and down) The brake pedal that is pressed on the brake. In this case, re- The answer is processing or replacement. Make sure that if the brakes are beating you check if they are worn out because when they arrive at this point they usually wear out more than their service life and the replacement is normal. Click sound when braking: this is a problem since the disc brake appears on site. The disc brake pads keep the pressure on the brake rotor in the appropriate position through the brake caliper. A little out of shape. Factory installation \"defense Stop the \"click\" device of the brake pad movement, which will stop the click. The equipment is made of spring steel. Over time, they become fragile and broken, making the brake pads travel loosely on the seat, making clicking and/or clicking during braking. Excessive drag during acceleration: does anyone feel like \"throwing an anchor\" during acceleration \"? Perhaps it is because the emergency brake cable is frozen due to the accumulation of rust and is not released. An easy way to avoid this is to use your emergency brakes! Remember this very simple rule. . . \"If you don\'t use it, let it loose! \"Light Up ABS lights: a lot of car experiences light up ABS lights with anti-lock brakes. In this case, check whether the harness and electrical plug that cause the wheel speed sensor are worn and corroded. These electrical components are affected by environmental conditions. Therefore, they are worn out due to exposure and may need to be replaced or repaired. You got it! Check the brakes every six months to avoid unpleasant accidents. Just by keeping a close eye on your brakes, the high dollar brake job can \"stop on the pass \". Until the next time. .
