WHAT ARE BRAKE PADS? WHAT ARE BRAKE SHOES?
car manufacturers install two types of brakes on passenger vehicles : phonograph record brakes and drum brakes. Both use clash to slow your vehicle, but there are differences excessively .
Disc brakes use “ pads ” of particularly engineered pieces of friction corporeal made of constituent, metallic or ceramic substances pressed against a rotor or “ disk ” when the driver steps on the brakes. The resulting friction slows the vehicle. Disc brakes are found on the front axles of all modern passenger vehicles and on the rear axle of many, excessively .
Drum brakes besides use friction material, much like disk brake pads, but it is affixed to half-moon shaped “ shoes ” pressed against the inside of a drum when you step on the brakes. Their friction against the drum slows the vehicle. Drum brakes used to be common on all four wheel positions, but on modern cars and light trucks, they ’ re only installed on the rear axle.
Whether pads or shoes, both wear down with use, so it ’ second significant to monitor their stipulate by having them inspected regularly. If allowed to wear out before being replaced, early components of the brake arrangement may be damaged – particularly the brake phonograph record or drums. In addition to frequently dearly-won repairs, driving with wear brake pads or shoes can result in insecure force conditions .
WHAT HAPPENS WHEN BRAKE PADS/SHOES WEAR OUT?
Every prison term you engage your vehicle ’ sulfur brakes, a small sum of clash fabric is worn off the pads and/or shoes. Over time, the friction corporeal will become flimsy. If the pads or shoes are not replaced, the clash fabric will be worn off wholly, exposing the steel pieces that held the material. When these steel pieces come into contact with the disk or drums, excessively hanker brake distances and damage to the disk and drums will result. Look for these signs to know when to replace brake pads or shoes :
1. SQUEALING OR SCREECHING NOISES
If a vehicle ’ s bracken pads have wear indicators, a driver may notice a screaky, screeching or whining randomness when the brakes are engaged.

If a audio disappears after the first few times you use your brakes, that ’ s a effective indicator that it was good a sting of moisture on the brake pads or shoes and not a sign they need to be replaced .
2. LESS THAN A QUARTER INCH OF BRAKE PAD
On disk brakes, you can besides visually inspect your brake pads to know if it ’ second clock to have them replaced, though it may require you to remove the wheels to do this. Looking down on the brake fabrication or “ caliper ” holding the brake pads, you should see your bracken pads compressed against your brake rotor. If the friction material on the pad or shoe is less than ¼ inch thick ( about seven millimeters ), consider having your brakes inspected, particularly if it ’ randomness been a long prison term since your stopping point inspection .
3. DEEP METALLIC GRINDING AND GROWLING
If you hear a deep, moo make noise that sounds like metallic element grind or a grumbling grumble, that can be a sign of the zodiac that not entirely are your brake pads worn away, but besides your brake pads or shoes ’ backing plates are making contact with the magnetic disk or drums. Since this metal on metallic liaison can very promptly cause even further damage in your brake arrangement, bring your vehicle in to a service patronize american samoa soon as potential if you hear this type of noise.
4. INDICATOR LIGHTS
Some vehicles have an indicator faint on the splashboard that will signal when it ’ south time to replace the brake pads. Check your owner ’ randomness manual to see if your vehicle comes equipped with the low-pad warn system. Remember that if the abstemious does come on, you ’ ll motivation to have your mechanic replace the warn sensors a good as the brake pads .
HOW LONG DO BRAKE PADS AND SHOES LAST?
The very answer to how hanker brake pads and shoes can last will vary from vehicle to vehicle and from driver to driver. For exemplar, if you tend to drive the most frequently in urban areas or in heavy commuter traffic, you ’ ll be engaging your brakes a batch more frequently than person who drives in rural locations or on highways. Some people besides tend to “ ride the brake, ” meaning they press and depress their brakes more habitually than early drivers, causing the brake pads to wear away more quickly. Brake pads and shoes are broadly thought to be good between 30,000-35,000 miles in urban practice. In less demand situations like highway tug in light traffic, brakes may last 80,000 miles or more .
