Brake Line Installation Instructions
A professional mechanic should do brake line installation. Read and follow installation instructions completely.
- Raise vehicle. Remove wheels and drain all brake fluid. Carefully remove existing brake lines from vehicle, avoid splashing paint work with brake fluid. Make note of positions of c-clip(s), locating tab(s), and banjo(s), if used. Remove all crush washers from their mating surfaces. Each new kit comes complete with all of the necessary OEM replacement adapters and banjo bolts.
- Clean all sealing surfaces and make sure they are in good condition.
- Fit Techna-Fit’s lines starting at the caliper and following the original path of the OEM lines. Use the new crush washers supplied in your kit. Ensure all locating tabs and mounting brackets are properly attached to their mating points on the frame or chassis and are not causing tension on either end of the connection. Do not fully tighten the bolts or threaded ends until the last step of the installation.
- Check that the lines are the correct lengths. The hose should not be kinked or twisted. The opposite axis torque lines should remain parallel along the entire length of the hose. Full travel of the suspension and steering must be checked to ensure the hoses are not stretched or trapped.
- Tighten banjo bolts and end fittings. If you’re tightening Techna-Fit’s hose to a factory hard line, the hard line must be held in place using the correct size wrench. Banjo bolts should be tightened to 12 to 14 (ft/lbs).
- You are now ready to bleed the brakes. You must use fresh DOT approved brake fluid and bled the system in accordance to the vehicles manufacturer’s recommendations.
- Before test driving your vehicle, make a final check of the brake lines to ensure all connections are tight and do not leak. The brake pedal should be firm at this stage. After 100 miles recheck all of the lines and connections for tightness and any leaks.
- It is not recommended to mix rubber hoses and stainless steel replacement lines on the same brake system.
- Do not try to force, rotate or stretch any stainless steel hose assembly; it may cause failure.

Proper Hose Measurement:
To insure the proper hose length; measure along the route you want your line to run using a lightweight wire. Plan your line route so that the lines will not get pinched. The length of the hose should be measured from the outside edge of one fitting to the outside edge of the other, as shown in diagram above.
