What size are Chevy brake lines?

Brake Line Sizes for Chevy Vehicles
The size of brake lines in Chevy vehicles can vary depending on the model and year. However, the two most common brake line sizes found in Chevy vehicles are 3/16″ (4.75mm) and 1/4″.
– The smaller size, 3/16″ (4.75mm), is found on virtually all cars and trucks made worldwide.
– The larger size, 1/4″, is most frequently found in short pieces between the master cylinder and ABS pump, as well as in the long run to the rear of full-sized cars, trucks, and hydraulic clutch lines.
It’s worth noting that some late-model GM and most European-built cars may have a larger line size of 6mm, and some Japanese trucks may have 1/4″ tubing.
To determine the diameter of your brake lines, you can measure them using a caliper. The 3/16″ size measures approximately 0.1875″.
Please keep in mind that these are general guidelines, and it’s always recommended to consult the specific vehicle’s manual or a professional mechanic for accurate information regarding brake line sizes.
