Analysis
NAICS 33634 is the 2022 NAICS industry for motor vehicle brake system manufacturing, part of 3363 (Motor Vehicle Parts Manufacturing).
It has only one more detailed code, 336340, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns counts 168 US establishments in this code in 2023, employing 20,474 people at an average annual payroll of $59,122 per employee (32nd percentile of national industries). 22% of the establishments have fewer than five employees, which points to larger operations.
By establishments it ranks 8th of the 8 codes at this level within Motor Vehicle Parts Manufacturing, with 3.6% of them.
Between 2018 and 2023 the number of establishments fell 8% and employment fell 16%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.
