Disc Dilemmas: Troubleshooting Your Toyota Highlander Brake Disc
It's suicidal to go driving with defective brake parts, as you may have seen in countless movie scenes where the villain drives to his death because his brakes are not functioning. Your wheels won't stop turning without the power of your brake system, so you must ensure all of its components are working properly before using your vehicle. Your Toyota Highlander brake disc is one of the parts that you should always keep an eye on because it is crucial in slowing and stopping your wheels at the right time. When your brake disc becomes damaged, your safety on the road will be compromised. Not only will you get into high-risk road accidents, but you will also face pocket-draining repair and replacement costs. Once you notice problems with your brake disc, it is important to do some troubleshooting right away. This will help prevent total brake system failure and also spare your brake disc from further damage. Read the guide below to find the causes behind brake disc problems.
Brake pedal vibration
This is a common danger sign usually connected with brake disc failure. The vibration may be similar to a pulsating sensation that can be felt each time you step on the brake pedal, and it may also result in wobbly braking. Bad brake discs may also cause vibrations in the steering wheel that can largely affect your vehicle's performance. Shaking and pulsating brake pedal sensations indicate warped brake discs, as their uneven shape prevents your vehicle from achieving a smooth stop. If not addressed immediately, this problem may lead to serious consequences, such as complete brake failure. To test the discs for damage, try to accelerate to around 30 mph and step on the brake pedal without stopping your vehicle completely. Performing this low-speed hard braking test will determine whether the discs are severely warped. If you can feel vibrations or pulsating sensations in the brake pedal and in the steering wheel while doing this test, then it's a sign that your brake discs need replacing.
Premature brake pad wear
Bad brake discs usually cause premature brake pad wear. If the surface of the disc is already too thin and slightly uneven, the brake pads will be forced to press harder in order to stop your vehicle. This causes the pads to wear out prematurely. If you're hearing screeching, grinding, or squealing noises each time you step on the brake pedal, then you should inspect both the pads and discs for damage. Replace these parts if necessary.
