Is 3 16 brake line the same as 4.75 mm?

The short answer is that 3/16 brake line and 4.75 mm brake line are not the same. While they may appear similar, they have distinct measurements and specifications that make them different. Let's dive into the details to understand the key differences between these two brake line sizes.


Brake Line Measurements: Inches vs. Millimeters


Brake lines are typically measured in either inches or millimeters, depending on the region and the specific application. In the United States, brake lines are commonly measured in fractions of an inch, such as 3/16 or 1/4 inch. On the other hand, in many other parts of the world, brake lines are measured in millimeters, such as 4.75 mm or 6 mm. The key difference is that 3/16 inch is not the same as 4.75 mm.


Conversion Between Inch and Millimeter Measurements


To understand the difference, let's look at the conversion between inch and millimeter measurements. 1 inch is equal to 25.4 millimeters. Therefore, 3/16 inch is approximately equal to 4.76 mm, not 4.75 mm. This small difference in measurement can be significant when it comes to the proper fit and compatibility of brake lines and their associated fittings.


Importance of Accurate Brake Line Measurements


Choosing the correct brake line size is crucial for the proper functioning and safety of your vehicle's braking system. Using the wrong size brake line can lead to leaks, improper fit, and potentially dangerous situations on the road. It's essential to always refer to the manufacturer's specifications and use the correct brake line size for your vehicle.


Conclusion


In summary, 3/16 brake line and 4.75 mm brake line are not the same. While they may appear similar, they have distinct measurements that make them incompatible with each other. When working on your vehicle's braking system, always ensure you are using the correct brake line size to maintain the safety and integrity of your brakes.

Is 3/16 the same as 4.75 mm?


3/16" (4.75mm): This is the most common size used in most passenger vehicles. It is often referred to as the "universal size" for brake lines. 1/4" (6mm): Typically found in trucks and larger vehicles, this size can handle higher pressure and is used in applications where the braking system requires more robust lines.

How many mm should brake lining be?


10-12 millimeters
A: New brakes pads are generally about 10-12 millimeters thick. At 3 millimeters the brakes are just about worn out and should be replaced. Replacing the front and rear brakes at the same time may save a little money and, certainly, your time without a car.



What is the common brake line wrench size?


Brake line wrenches (often called flare nut wrenches or simply line wrenches) serve a specific purpose in a mechanic's toolbox. Several styles exist, but determining which brake line wrench is right for my vehicle isn't really that hard. Most domestic cars use a 7/16-in. size, while imports typically use a 10 mm.



What is the difference between 1 4 and 3 16 brake line?


The size of the brake line is ultimately determined by the hydraulic system that the manufacturer used. Both sizes, 3/16" and 1/4", deliver the pressurized fluid equally so nothing would be gained by switching to the 1/4".



How to measure 3/16 brake line?


You can also use a 1/4" open end wrench to gauge your lines. It will fit easily onto 1/4" line and will bang back and forth on 3/16" line. A stack of three pennies is about 3/16" thick and three pennies and a nickel are around 1/4" thick. On some late model GM and most European built cars the larger line will be 6mm (.
