Frequently Asked Questions

Every Brake Line Pros hose is built and tested in the USA at our shop in Holt, FL. We are not a warehouse operation or a drop-ship catalog. We build each hose ourselves and inspect it before it ships.

Yes. Every Brake Line Pros hose is DOT and NHTSA certified to Federal Motor Vehicle Safety Standard 106. Each hose is pressure tested and individually inspected before it ships.

All Brake Line Pros brake lines are compatible with all DOT brake fluids including DOT 3, DOT 4, DOT 5.1, and racing brake fluids. The PTFE inner core is chemically inert and will not react with any DOT fluid.

We currently build brake lines for Toyota platforms including Tacoma, 4Runner, Tundra, Sequoia, FJ Cruiser, and Land Cruiser across all generations, Lexus GX470, GX460, and GX550, and UTV applications. We also build custom brake lines for Ford, Jeep, GM, Ram, Porsche, performance, and any application with non-factory routing.

For lifted trucks, off-road use, towing, UTVs, and drivers who want firmer pedal feel, braided stainless steel brake lines are often better than rubber. For a stock commuter, quality rubber hoses may be acceptable if in good condition. Stainless lines resist expansion under pressure, which produces a firmer and more consistent pedal feel. See the full comparison at Stainless Steel vs. Rubber Brake Lines.

They can improve pedal firmness, but they will not fix air in the brake system, fluid leaks, bad calipers, worn pads, or incorrect installation. Diagnose those issues before replacing the hoses.

Many lifted trucks do, but lift height alone is not enough to decide. Check brake hose slack at full droop and steering lock. A 2-inch lift often does not require extended lines but a 3-inch or taller lift frequently does, especially on the front of Toyota trucks and SUVs.

Street-driven vehicles should use DOT-compliant brake hoses made for the application. Every Brake Line Pros hose is DOT and NHTSA certified for street use.

Measure along the routed path at full suspension droop, not in a straight line between fittings. Use a string or flexible wire to trace the actual arc the hose will follow, then measure that string. Add a small amount of slack for movement. The routed length at full droop is always longer than the straight-line distance. See the full guide at How to Measure Brake Lines.

Stainless braided lines have fixed ends. The exit angle and rotational clock position are set when the hose is built and cannot be adjusted in the field. If the exit direction is wrong, the line will fight the routing, contact suspension components, or pull at the fittings. It has to be built correctly from the start.

Clock position describes the rotational orientation of the fitting exit angle. If a banjo fitting exits at 90 degrees, the clock position tells you which direction that points. Up is 12 o'clock, outboard is 3 o'clock, down is 6 o'clock, inboard is 9 o'clock. Two hoses with the same exit angle but different clock positions will route in completely different directions.

Yes. You can measure yourself with a string or flexible wire, a tape measure, and a few reference points. The process is the same whether you do it at home or in a shop. The key is getting the vehicle to full droop during measurement and identifying the fittings correctly. For custom builds, detailed photos from multiple angles are the best supplement to your measurements when ordering.

The three things to identify are fitting type (banjo, inverted flare, bubble flare, AN-3), thread size (SAE or metric), and exit direction. A thread pitch gauge confirms the thread. If you are unsure, contact Brake Line Pros with photos of both ends and we can help identify them. See the full guide at Brake Line Fitting Guide.

Inverted flare fittings use a 45-degree conical flare and are standard on most North American vehicles. Bubble flare fittings use a rounded convex flare and are common on import and European vehicles. They look similar but are not interchangeable. A bubble flare seated against an inverted flare seat will not seal and will leak under pressure.

Most Toyota and Lexus calipers use a 10mm banjo fitting. Some larger Toyota and Lexus platforms use a 12mm banjo. Hard line connections on most Toyota platforms use metric bubble flare fittings at M10x1.0 or M12x1.0 depending on the platform and year. Always confirm with a thread pitch gauge before ordering.

AN-3 fittings use a 37-degree flare seat and are standard in off-road, UTV, racing, and aftermarket big brake kit applications. They are available in straight, 45-degree, and 90-degree configurations and are common in purpose-built off-road and performance builds.

Yes. A rear shock relocation on a Tacoma is one of the clearest cases where extended brake lines are an absolute requirement. Factory Tacoma rear brake lines are around 16 to 17 inches. Brake Line Pros extended lines for that application are 24 inches. The factory lines will not reach with a shock relocation installed.

Yes. Long-travel suspension significantly increases suspension droop travel, meaning the brake hose has to span a much greater distance at full extension. Factory brake lines will pull tight or fail to reach entirely on long-travel builds. Extended brake lines are required for any Toyota or Lexus platform running long-travel suspension.

Yes. At 3 inches of lift with the suspension at full droop, factory brake lines on Tacoma, 4Runner, FJ Cruiser, and Lexus GX platforms will have tension and may not allow full suspension travel. Extended brake lines are strongly recommended at 3 inches and above.

Not always, but it depends on your bump stop setup and total shock travel. At 2.5 inches the factory lines may still have adequate slack, but if you have removed or trimmed bump stops, run longer shocks, or have additional suspension travel beyond the lift height itself, extended brake lines are a worthwhile upgrade. Check brake line slack at full droop before deciding.

Yes. Any time a brake line is disconnected, air can enter the system and the brakes must be bled before the vehicle is driven. A proper bleed ensures no air remains in the lines and the pedal is firm before use.

After installation, check for leaks at all fittings, bleed the brakes completely, verify the hose has no tension at full droop, confirm clearance from shocks, CV axles, control arms, and tires at full lock in both directions, and inspect the line again after the first drive for any contact marks on the braid.

A soft pedal after installation is almost always air in the system. Bleed the brakes thoroughly at all four corners. If the pedal is still soft after a complete bleed, check for leaks at the fittings, confirm the hoses are the correct type for the application, and inspect the rest of the brake system including calipers and master cylinder.

Do not drive the vehicle until the contact point is resolved. A brake line that contacts a moving suspension component will wear through over time and fail. Check the routing at full droop, full compression, and full steering lock in both directions. If the line is too long, too short, or the exit angle is wrong for the application, contact us and we will work through the issue with you.

All Brake Line Pros hoses carry a 5-year warranty against manufacture defects. The customer is responsible for return shipping on warranty claims.

Unused items may be returned within 30 days of purchase. Free return shipping is provided by Brake Line Pros on eligible returns.

Contact us through the contact page or email info@brakelinepros.com with your order number and a description of the issue. For warranty claims, include photos of the defect. We will respond within one business day.

Yes. Brake Line Pros builds custom stainless steel brake lines for any application including non-factory routing, aftermarket calipers, long-travel suspension, straight axle swaps, UTVs, big brake kits, and performance builds. Submit your details through the custom brake line order form.

You need the fitting type and thread size at both ends, the exit angle and clock position at both ends, the hose length measured along the routed path at full droop, and your vehicle and application details. Photos of each fitting end and the overall routing are helpful and can be emailed to info@brakelinepros.com.

Yes. Straight axle swap applications require measuring from scratch since the OEM routing no longer applies. The caliper location, hard line end location, and routing path are all determined by the build. Contact us with your build details and we will help you figure out what is needed.
