Signs of a Damaged Bmw X5 Brake Disc
The big and imposing Bmw X5 needs good brakes that can control the weight and demands of this crossover SUV. With this in mind, worn Bmw X5 brake discs should be replaced as soon as possible. You wouldn't want to be driving the car with faulty ones. Doing so would mean putting yourself in an uncontrollable car you're not even sure if you can properly stop. Before you drive the X5 and realize the brakes are unreliable, there are indicators on the discs that can tell you they are in need of replacement. Look for these signs of a damaged brake disc during routine inspection:
A Bmw X5 brake disc with a warped surface is a sign that you should replace these at once. This symptom is usually caused by the uneven torque of the bolts that secure it in place during installation. Make sure that you tighten the bolts properly, following the correct sequence and torque specifications, to prevent this problem from happening again.
Brake discs are designed to be used only up to a specified limit. If the surface appears to be forming patches of rough spots, blue streaks, and other odd colors, it means the rotors are being subjected to high-intensity braking. Going beyond this and you're already pushing the discs beyond safe limits.
Rust on a brake disc should be expected as part of its regular wear-and-tear. When you see too much corrosion on the rotor, this is usually due to your X5 not being used for a long time. The brakes that used to be very hot have cooled and have invited the elements that promote rust to affect it. This problem can be avoided by simply using your Bmw X5 as often as possible.
Scars, cracks, and deep grooves are usually caused, not by bad discs, but by thin brake pads. With thin pads, their metal case ends up rubbing and scratching the surface of the rotor. Light scuffs can be sanded and grinded to achieve an even surface. If unnoticed or left unattended, the small scratch will grow to become a major problem.
Taking Care of Bmw X5 Brake Discs
Since Bmw X5 brake discs play a big role in your ability to stop and control the vehicle, ensuring that these are in good operating condition should be one of the top items on your maintenance checklist. Bad ones could be disastrous for you if you fail to look after their needs. Maintenance of these parts should begin the moment you use or install new brake parts on your car. Follow these simple tips on how to take care of and prolong the service life of your brake discs.
Change discs in pairs.
For a balanced Bmw X5 brake disc assembly, it is recommended that you replace worn out ones in pairs. This would give you more stability and control when driving. The uniform discs also make it easier on the brakes system to apply even pressure for stopping.
Replace old brake pads.
Taking care of brake discs also mean taking care of the brake pads being pressed on these. Many problems with old rotors are caused by the pads that are already way past its service life. Thin ones eventually lose the semi-abrasive compound it's made of. As a result, there is metal-to-metal contact between the Bmw X5 brake disc and pad every time you step on the brake pedal.
Run in the brakes upon replacement.
Failure to run in new brake parts is a common error among people who service their brake discs. This should be mandatory because this is the final setup stage that ensures contact is properly established between pad and disc. This is the time for new pieces to warm up and be familiar with the nature and demands of your car.
Use your car frequently.
One common complaint when it comes to the Bmw X5 brake disc is the accumulation of rust on the surface. Some corrosion is normal. However, too much of it is a sign that you're doing something wrong. Letting your car sit for a long time allows the elements to react on the metal and create rust. Simply use your car as often as possible to limit this occurrence.
