What is the minimum thickness of brake rotors on a Lexus is250?
The minimum brake rotor thickness for a Lexus IS250 is 12 millimeters (mm) or 0.47 inches. This specification is critical for ensuring the proper functioning and safety of the vehicle's braking system.
Understanding Brake Rotor Thickness
Brake rotors, also known as discs, are an essential component of a vehicle's braking system. They are responsible for converting the kinetic energy of a moving vehicle into heat energy, which is then dissipated through the brake pads. The thickness of the brake rotor is an important factor in determining its durability and performance.
As the brake pads press against the rotor during braking, the rotor's surface gradually wears down. Over time, the rotor's thickness decreases, and it becomes necessary to replace the rotor to maintain the vehicle's braking efficiency and safety.
Minimum Brake Rotor Thickness for Lexus IS250
The Lexus IS250 is a compact luxury sedan that was produced from 2005 to 2013. According to the manufacturer's specifications, the minimum acceptable brake rotor thickness for this model is 12 mm or 0.47 inches.
It's important to note that the minimum thickness is the lowest allowable measurement before the rotor needs to be replaced. Driving with rotors that are thinner than the minimum specification can lead to decreased braking performance, increased brake pad wear, and potentially dangerous braking conditions.
Checking and Replacing Brake Rotors
- Regularly inspect the brake rotors for signs of wear, such as grooves, cracks, or uneven surfaces.
- Measure the rotor thickness using a micrometer or caliper to ensure it meets the minimum specification.
- If the rotor thickness is below the minimum, it's recommended to replace the rotors and brake pads as a set to maintain optimal braking performance.
- Consult your Lexus owner's manual or a qualified mechanic for the specific replacement procedures and parts required for your vehicle.
Maintaining the proper brake rotor thickness is crucial for the safety and performance of your Lexus IS250. By regularly inspecting and replacing the rotors as needed, you can ensure your vehicle's braking system remains in top condition.
How much brake rotor wear is acceptable?
This lip is created as the brake pads normally don't contact all of the rotor surface and therefore leaves an outer lip when the rotors are worn down. Keep in mind that rotors reach their wear limit at only about 1mm. If there is an obvious lip, it's most likely near it's wear limit or is wearing unevenly.
How much do Lexus rotors cost?
Lexus RX 350 Brake rotor replacement can cost anywhere between $300 - $750 for all four rotors to be replaced. This price estimate includes labor and parts.
Can rotors last 200,000 miles?
Generally speaking, brake rotors usually last between 30,000 and 70,000 miles before they need to be replaced or resurfaced.
What is the minimum thickness of brake rotors?
Brake rotors are marked with a “minimum thickness” on the casting (usually 2 mm to 3 mm less than the new rotor thickness). Rotors should be replaced before they reach this minimum thickness and should not be “turned” (machine refinished) below this.
What is a fair price for front brakes and rotors?
Based on our research and also our own experience, we found that the average price range for a brake service is $250 to $500 per end of the vehicle (front or back). Figure on average a brake pad and rotor replacement has an average cost of $350 for each end of the car (front or back).
At what measurement should brake rotors be replaced?
Within the veins of the rotor. Or on the head of the rotor. To accurately measure against the minimum thickness using micrometer at several points on the surface of the rotor where it meets the pads.
How long do Lexus brake rotors last?
30,000 - 80,000 miles
The answer depends massively on your driving style, the conditions of your daily commute, the type of rotors, and the type of vehicle you're driving. Typically, Lexus rotors need to be totally replaced each 30,000 - 80,000 miles depending on the factors above.
How thin is too thin for brake rotors?
A brand new Shimano rotor is 1.8 mm thick. Every brand of disc brake rotors—Campagnolo, SRAM, Shimano, Tektro, etc. has a minimum thickness; when your rotors get this thin, they want you to replace them. Shimano for example recommends that its rotors be replaced when worn down to 1.50 mm.
How much does it cost to replace brakes on a Lexus IS250?
The average cost for a Lexus IS250 Brake Pad Replacement is between $267 and $320. Labor costs are estimated between $81 and $103 while parts are priced between $186 and $217.
What is the minimum brake rotor thickness for a dot?
An air braked commercial motor vehicle shall not be operated with brake lining/pad thickness less than 6.4 mm (1⁄4 inch) or to the wear indicator if the lining is so marked (measured at the shoe center for drum brakes); or less than 3.2 mm (1⁄8 inch) for disc brakes.
