Fix My BMW: When It’s Time for New BMW Brakes
If your BMW was made after 1982, you should get an import brake job that will replace all pads and rotors as soon as the indicator light goes off on your dashboard for your BMW brakes. It sounds expensive, but there are benefits in the long run to this proactive approach.
The brake light sensor comes on when one of the sensors in your BMW braking system has been activated. The light for the BMW scheduled maintenance for your brakes will come on when the pad wears down enough to set off the sensor in that pad. There is no sensor in the rotor. The rotors have a specified minimum thickness in order to properly dissipate the heat, provide great braking performance, and prevent warping in the rotor. If the rotor is below this thickness, it will have to be replaced by your BMW mechanic for you to have the best braking power possible.
The more weight you have near the wheels, the more it can affect your car’s agility and performance. Brake rotors are heavy by their nature;they have to be sturdy to make sure that you stop. Because a BMW’s performance is so important, BMW uses a thinner rotor, and you can definitely feel that difference when on a tight curve. The only negative is that you can usually only use these thinner brake rotors with one set of pads. But this is one of the worthwhile costs of having a high performance machine.
Needing to Change The Rotors is Not Your Fault or the Mechanic’s
Don’t hold it against your BMW mechanic that he has to charge you for new rotors. And don’t feel that it was your mistake for you putting off the brakes too long that made your repair more expensive because of the rotors. That’s just the nature of BMW and brakes. It’s the intrinsic cost of having such a supreme machine. When you have all of BMW’s torque and power, you want to make sure you have all of the braking power of fine European brakes on your side as well.
Ready for New Brakes? Get Your Brake Fluid Checked Too
In addition to your brakes and your rotors, you should also get your brake fluid checked regularly. BMW recommends having your brakes flushed every 60,000 miles. The reality is that your brakes are theoretically part of an enclosed system. Assuming there are no leaky parts, you should be able to run on the same fluid almost indefinitely. But the brake components naturally wear down over time, which can cause water, debris and other contaminants to leak into the brake fluid and gunk up your brake infrastructure.
Our BMW mechanics recommend you have your brake fluid checked periodically rather than doing brake flushes all of the time. Your BMW brake fluid should be a nice translucent color. If it’s dark brown, you should probably have your BMW technician flush the system and add new fluid.
