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:
Disc warping
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.
Odd colors
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.
Excessive rust
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.
Deep grooves
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.
