How come I have to change my BMW brake disc already?

Question

Whats with this people wanting to change my brake disc of a 2 year car ?

I have a Toyota and I change the brake this like one time, and it have 14 years (2002)

I understood that the brake disc deteriorate if you dont change your brakes pads on time, when is needed

I have only change my brake pads on time and was on time, as soon as the light sensor went off, I change the pads

Now the sensor is on and I went where I bought the car to buy my pads but it seems they want me to change both front brake discs, so I went to another recognize BMW part shop and they told me I need to change the four of them!

I want second opinion on this cause I dont think its that neccesary or it deteriorate that fast

With your opinion I'll check again in a particular mechanics and see if Im a need of new brake disc

Thanks in advance

Answer 1

You really must not have driving your Toyota that much or did much braking in that vehicle, or your driving habits have changed with the BMW over the Toyota.

My wife's 2003 Corolla needs a brake job about every 18 months. She drives in very hilly areas and applies her brakes more frequently.

I drive a 2004 Pontiac Vibe (the same as a Toyota Corolla with a different upper shell). Have not had to replace the brakes yet and last inspection still had 50% of my brake pad left.

Brake pad replacement depends on your driving habits and braking frequency. It doesn't hurt to get a second opinion. (It rarely ever does), but not sure how you got 14 years on a single set of brake pads unless you didn't drive that much.


Ok, your talking about the disk rotors, I misunderstood your question. These days manufactures do make rotors out of cheaper metals to minimize brake noise. You can purchase rotors made from higher quality metals that last longer from an auto parts store. Just ask them for the higher quality rotors.

Most manufacturer's have a minimum thickness that is recommended for the rotors as well. These days they don't make rotors as thick to reduce weight and allow for better cooling of the brake area. This unfortunately amounts to having to change the rotors a bit more frequently. From personal experience this is typically every other brake job for the original OEM brake rotors. (ie you can get them turned(machined) once, but typically not twice)

Next time you have the brake rotors replaced, ask for the higher quality rotors. They are more expensive (typically by 50% more), but they will keep you from having to replace them as frequently.

Answer 2

BMWs are heavier,tires are wider,wheels larger and speeds greater which puts stress on the braking system.Brake repair produces the greatest profits and people do not resist because it is a safety issue.Air conditioning in Florida is a must so people bend over and accept the price for repairs.You could do the work yourself if you were the ultimate repairing machine,if mechanics make $50 an hour then every hour you spend under the hood is a pay raise.Get rid of those projector headlights before damage is done to your chassis and the loot fenced on eBay.

Answer 3

Many new cars need complete brake overhaul after two years, when I first heard of this it surprised me as well. I think it has to do with the cars sitting on lot for long time and actually starting to rust and detoriate just sitting there. You would never think to pop off the tires and check out brakes before buying on a new car, but maybe you should.

Answer 4

if the pads wernt grinding and there was not plusating of the brake petel or shaking the rotor its fine. normaly when u have your brake pads replaced they want to replace ur rotors.
