Disc Brake Rotor Minimum Thickness Chart

Disc Brake Rotor Minimum Thickness Chart - As shown here in figure 1 the base brake article contains a section titled technical specifications. If your rotor has worn past this thickness or needs to be cut, you need new rotors. Choosing to ignore rmt is a safety risk. Refer to relevant service information for unknown vehicles. Continued use of disc rotors below rmt can lead to brake system failure. Web measure rotor disc thickness at a minimum of six locations, but preferably at eight equidistant points along the rotor — at 12 o'clock, 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees, 270 degrees. Web most specifications for rotor thickness are found in the “base brake” articles. Web each vehicle manufacturer specifies a minimum thickness for brake rotors, which is the lowest allowable measurement for safe operation. Disc brake rotor minimum thickness (rmt) is the minimum safe working thickness of a rotor. These specifications are typically found in your vehicle’s owner’s manual or the vehicle’s repair manual or stamped directly on the rotor.

This is usually found on the hat (the central portion of the rotor), within the cooling veins, or on the outer edges. Web the average difference between nominal and machine to thickness is.050″ to.060″. Web measure rotor disc thickness at a minimum of six locations, but preferably at eight equidistant points along the rotor — at 12 o'clock, 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees, 270 degrees. As shown here in figure 1 the base brake article contains a section titled technical specifications. Web each vehicle manufacturer specifies a minimum thickness for brake rotors, which is the lowest allowable measurement for safe operation. Web to measure your rotor’s minimum operational thickness, place a micrometer at the thinnest point on the rotor’s surface where it meets the brake pads. Choosing to ignore rmt is a safety risk. When a disc rotor reaches rmt it must be replaced. Your rotor may exhibit signs of disc thickness variation (dtv). The lowest value should be used as reference for the entire rotor.

Web Rotors Have A Minimum Thickness That Is Typically Written On The Side Of The Rotor.

Discard thickness the discard thickness of a rotor is the thickness at which the rotor should be replaced. Refer to relevant service information for unknown vehicles. Nominal size thickness minus 1.6 mm. ** not serviceable, replace at each brake job if grooved or undersized.

Web When It Reaches What We Call The “Minimum Thickness”.

Regularly measuring brake rotor wear is important to maintain braking efficiency and avoid costly consequences. Developed and manufactured under iso/ts 16949 standards. Measurements vary from 1.7mm to 1.5mm. Web most specifications for rotor thickness are found in the “base brake” articles.

Web Locate The Minimum Thickness Standard:

If your rotor has worn past this thickness or needs to be cut, you need new rotors. The lowest value should be used as reference for the entire disc. Web measure rotor disc thickness at a minimum of six locations, but preferably at eight equidistant points along the rotor — at 12 o'clock, 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees, 270 degrees. Continued operation at or below rotor minimum thickness can lead to brake system failure.

These specifications are typically found in your vehicle’s owner’s manual or the vehicle’s repair manual or stamped directly on the rotor. Different brands recommend different minimum thicknesses so check the details for the rotors you use. This is usually found on the hat (the central portion of the rotor), within the cooling veins, or on the outer edges. Web the minimum thickness for general inspection (motor vehicle inspection) is defined as follows:
