Why do life time breaks squeek?

Answer 1

Brakes that have a lifetime warranty are typically made of harder material than those that are not guaranteed for a lifetime. This makes it worthwhile for the manufacturer, because lifetime pads typically places more wear on your rotors and you'll need to replace those more freqently since rotors are more expensive and nobody guarantees those for a lifetime.

The harder material on the pads wearing down the rotors is what you're hearing as squeal.

Answer 2

Multiple part answer: 1. Some brakes squeal because the pads or shoes are made of more durable material than normal brakes. When I asked for these I was warned that these pads cause the front rotors to wear out much faster than normal. (Has anyone else been told this?)
2. More likely 'Lifetime' may just mean that the brakes will be replaced free when they wear out. If this is the case, the cause of squeals may be the sensors that warn you the brakes are wearing thin. Again, 'Lifetime' may mean they will be replaced at no cost if/when they wear out not that they will last forever. Of course shops charge for installing the new 'free' ones but it may still be a good deal.

3. Any brakes will make noise if foreign objects or contaminants are on the pads. In any event have it checked by someone you trust.

Answer 3

**********************************************

There is full lifetime brake pads which will still wear down over a long enough time depending on your braking habits. If you drive fast, you most likely brake harder. These are fully warranted for the life of the car as long as you own it.

Then there are limited lifetime brake pads. These are guaranteed against any manufacturing defects. Meaning they won't crumble, or fall apart. And if they do, they will be replaced. But these are not warranted against wear.

ALL brakes can sqeak. Dirt, grease, or debris get between the brake pad and the rotor. That is what is squeaking. Not the brake itself. This can come from a persons hand when the brakes were installed, a mud puddle when it rains, a gravel road...the origins of foreign materials are too numerous. Just imagine what your tire is driving through everyday.

And if you have had those brakes for a long time, they may have worn and the warning tabs are squeaking. These special tabs are designed to touch the rotor when the pads wear down thin so as to warn you to have them checked. This can prevent you from allowing the pads to wear out completely and have the steel backing of the pad scraping against the rotor and ruining it. This can make an $80 brake job become a $400 brake job.

Answer 4

Usually depends on the install and the preparation of the rotors. Seems if you don't resurface the rotors, the old brake pads may have left a groove in the rotor which is similar to the grooves in an old vinyl lp record, when a piece of dirt or old brake lining has been left ion the rotor it causes the noise you are hearing. You, also, want to place some anti-seize lubricant on the brake pads where they come in contact with metal,as this will eventually rust and cause a squeak. Hope this helps, Good Luck.

Answer 5

U need 2 apply break-oil 2 the breakes 2 stop it from squeeking.

Answer 6

The brake pads may last forever. Break dust and road debris work their way into the braking system (pads, rotors, between pads & rotors, between pads & pistons). With all this junk floating around, the pads won't make a positive contact to the rotors causing them to vibrate and instead of the pads rubbing on the rotors the debris is scraping on the rotors.
Remove the calipers and clean the pads and rotors with "contact/brake cleaner".

Answer 7

I've had the same problem (from Midas Muffler and Brakes).
The harder material makes the linings last longer, but because of that, they tend to sqeak and wear out disc rotors and drums quicker.

Answer 8

think about what they do, they squeeze very hard on to a metal rotor to stop a fast moving heavy object. it seems to me there has to be some noise associated with this. If your brake pads are worn there is a metal spring attached which touches the rotor and squeaks this is to tell you they are worn and need replaced. what ever you do don't put oil on them if you do you will be having a rear end collision.

Answer 9

better check the calipers.i get lifetime pads all the time and mine dont squeek.

Answer 10

They get dirty from use. When you wash your car, hose down the brake parts through the spaces in the wheels. That should take care of at least some of the squeaking.
