What size brake line is a 1995 Toyota 4runner?
Front brake lines are 3/16 inch in diameter, while rear brake lines are 1/4 inch in diameter.
In this article, we break down the standard hard-line sizes used on the 1995 Toyota 4Runner, explain where those lines run, and how to verify the exact measurements for your vehicle. We also touch on related considerations when replacing lines, such as material and fittings.
Brake line sizes by location
Below are the typical hard-line diameters used on the 1995 4Runner, with front lines smaller than rear lines.
- Front hard lines: 3/16 inch (4.75 mm) diameter steel tubing.
- Rear hard lines: 1/4 inch (6.35 mm) diameter steel tubing.
These measurements refer to standard automotive steel hard lines. Variations can exist by market or production run, so it’s wise to confirm with the vehicle’s service manual or a Toyota parts diagram.
Verifying sizes on your 4Runner
To ensure you’re using the correct lines for your exact vehicle, perform a quick check against official diagrams and physical measurements.
- Consult the factory service manual or an official Toyota parts diagram for your VIN/market.
- Measure the tubing diameter directly on an existing line if you have access to one.
- Compare the measured size to standard 3/16" (4.75 mm) and 1/4" (6.35 mm) tubes to confirm which applies to the front and rear lines.
- If replacing lines, ensure you purchase the correct length and routing for your vehicle and follow proper flaring and mounting procedures.
With the correct size confirmed, proceed with proper installation and bleeding procedures to maintain braking performance and safety.
Replacement considerations
When replacing brake lines on a 1995 4Runner, consider using copper-nickel alloy lines for easier bending and corrosion resistance. Use the appropriate flare type and ensure all connections are leak-free after installation. Bleed the brake system thoroughly after replacement to restore pedal feel.
Summary
For a 1995 Toyota 4Runner, the front hard brake lines are typically 3/16 inch in diameter, and the rear hard brake lines are typically 1/4 inch in diameter. Always verify with your vehicle’s service manual or Toyota diagrams, as regional variations can occur. Accurate sizing is essential for a proper fit, safe braking performance, and a successful repair.
Are most brake lines 3-16?
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 do I know my brake line size?
To measure a brake line, use a caliper to measure its outer diameter, or a thread gauge to measure the thread pitch for the fitting. Alternatively, use a quick-check method with wrenches or coins. Always start by consulting your owner's manual for vehicle-specific information.
Using a caliper and thread gauge (most accurate)

- Measure the outer diameter: Use a caliper to measure the outer diameter of the brake line itself. Take readings at multiple points to ensure accuracy.
- Measure the thread pitch: Use a thread gauge to measure the distance between the threads on the fitting. For imperial sizes, measure the threads per inch (TPI); for metric, measure the distance in millimeters.
- Identify the size: Use your measurements and a reference chart to identify the correct brake line size and fitting type.
- Convert units if needed: To convert inches to millimeters, multiply by 25.425.425.4. To convert millimeters to inches, divide by 25.425.425.4.
Using common objects (for quick checks)

- Wrenches: A wrench that fits the line snugly is the correct size (e.g., a 1/41 / 41/4 inch wrench on a 1/41 / 41/4 inch line). A wrench that rattles loosely indicates a larger size (e.g., a 3/83 / 83/8 inch wrench on a 5/165 / 165/16 inch line).
- Coins: A stack of three pennies is approximately 3/163 / 163/16 inch, while a stack of three pennies and a nickel is about 1/41 / 41/4 inch thick.
Before you begin
- Consult the owner's manual: Check your owner's manual for the correct specifications before taking any measurements.
- Be aware of variations: Some modern vehicles use different sizing standards, such as 6mm, which is slightly smaller than 1/41 / 41/4 inch.
What size brake lines does Toyota use?
It should be a standard 3/16 m10-1.0 brake line. Toyota only uses double flare and never bubble flare. Any auto store will have them in various lengths.
