Toyota Highlander Brake Disc

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.

  • Disc Care: Top Tips in Maintaining Your Toyota Highlander Brake Disc 27 February 2013

    Brake system maintenance doesn't stop on the pads, pedal, and calipers. It should also involve routine brake disc inspection and cleaning. Caring for your Toyota Highlander brake disc not only ensures safe driving, but it also promotes better brake system performance. Over time, the brake disc may wear out and become warped, causing braking problems that can jeopardize your safety. But with proper care and maintenance, you can prolong the life of your brake disc and also avoid high repair costs. Follow the tips we've listed below to keep your Toyota Highlander brake disc in good condition.


    Clean your brake disc regularly.


    Since your brake disc is not exposed to sunlight, it is more vulnerable to rust caused by moisture buildup. When not addressed right away, the outer surface of the disc may become completely corroded, forcing you to get a replacement instead of removing the rust. Aside from looking unsightly, rusty brake discs may also perform poorly. To prevent rust from building up, you need to clean and lubricate your brake disc regularly. An aerosol brake cleaner or a commercial cleaning spray is highly effective in removing dirt from the disc. Make sure to clean the entire disc thoroughly in order to eliminate even the most stubborn grime from the surface. To remove rust buildup, apply an oil- or aerosol-based lubricant on the disc. You may also use a rust remover solution that contains zinc phosphate to coat the disc's metal and protect it from rust.


    Do routine visual inspections to measure the brake disc's thickness.


    Performing routine visual inspections will not only reveal signs of ridges and scores on the disc, but it will also allow you to measure the thickness of the brake disc. To prevent the disc from becoming too thin, you need to get its measurement regularly. A simple device called a micrometer may be used to measure the thickness of the brake disc. If the damage on the disc surface is minimal, then a mechanic can simply machine or resurface it to restore its condition. Otherwise, replace the damaged disc to avoid braking problems.
