Understand your car brake system - General

[Rogan]

[h=2]Discover how to help escape costly auto brake repair bills with regular inspections.[/h]When your car brakes (pads, linings, shoes) are almost worn out, metallic tabs will create a squealing noise when the brakes are applied to alert you that the brake linings are due for replacement. Heed the warning. If you ignore the warnings long enough, you can do costly damage to the rotors, drums and other components. This will likely lead to an unpleasant auto brake repair bill.

Even with regular replacement of the linings, some additional service is typically required over the long haul. The surfaces of drums and discs wear unevenly in normal use and eventually need to be remachined or replaced to work properly.

Help avoid costly accidents or auto brake repair bills repair by routinely checking your car brakes. Here’s how to do it yourself.

The brake system works by your foot pushing a piston that pushes fluid through the brake lines, which creates hydraulic pressure that applies the friction materials against rotors or drums.

[*]Car brake pad indicators are designed to emit a scraping sound when the pads are worn out. If you hear this sound or a grinding sound when you apply your brakes, they need replacing.

[*]A car brake pedal that continually creeps toward the floor while you are stopped indicates problems in the hydraulic system, such as air bubbles, leaking internal seals or an external leak.

[*]Most hydraulic system problems are from contaminants in old brake fluid, which pulls water out of the air. They can corrode metals and destroy the rubber seals.

[*]Locked auto brakes do not stop as quickly as brakes on the verge of lockup. ABS (anti-lock brake systems) use sensors to prevent any wheel from locking up, and provide shorter stopping distances.

[*]Inspect the fluid level in your master cylinder regularly. As the friction materials wear, more fluid is displaced to the wheels. A sudden drop in the fluid level indicates problems.

[*]Your brake fluid should be a clear amber color. If it is cloudy or brown, have it flushed completely, as this indicates the presence of water and corroded metal.

[*]Always use fresh brake fluid from a sealed container and make sure to check for the proper DOT (Department of Transportation) specification number for your car.

[*]If your car brake pedal becomes hard to depress, check for vacuum leaks around the hose that connects to the brake booster canister. (See your repair manual.)

Suggestion:I visually look at the thickness of the pad and the condition of the rotor or drum if applicable, when rotating tires. (It's a pain, but the extra time to pull the drum is worth it at that time.)And when the tire is off, I use silicon to clean and protect the rubber hoses at each tire rotation or every other time. This prevents cracks in them.
