How Long Do Brake Shoes Last on a Semi Truck?

Semi trucks have a lot of components that need to be properly maintained in order to keep them running smoothly. One of those components is the brake shoes which are a crucial part of the braking system.

The brake shoes are responsible for providing the necessary friction to slow and stop the semi truck. But, how long do brake shoes last on a semi truck?

In general, brake shoes on a semi truck should be replaced every 100,000 to 200,000 miles. This is because the brake shoes can wear down over time due to normal use and exposure to heat and moisture.

Additionally, if the brakes are not regularly inspected and serviced, then this can lead to premature wear of the brakes as well. It’s important to note that it’s best practice to replace both the left and right side of the brakes at the same time since they both wear down together.

Signs That it’s Time To Replace Semi Truck Brake Shoes

  • Excessive Noise – If your semi truck is making grinding or squealing noises when you apply the brakes then this could be a sign that it’s time for new brake shoes.
  • Vibrations – If you feel vibrations when applying your brakes then this could indicate that your brake shoes are worn down.
  • Brake Pedal – If your brake pedal feels soft or spongy then this could also be an indication that you need new brake shoes.

Cost of Replacing Semi Truck Brake Shoes

The cost of replacing brake shoes on a semi truck will vary depending on several factors such as make and model of truck, as well as where you get them from. Generally speaking, you can expect to pay anywhere from $500-$1000 for new brakes depending on these factors.

Conclusion

Brake shoes are an integral part of keeping your semi truck running safely and efficiently.

They should be replaced every 100,000-200,000 miles in order to ensure optimal performance. The cost of replacing them can range from $500-$1000 depending on make and model of truck as well as where you purchase them from. It is always best practice to replace both sides at once so that they both wear evenly over time.
