HALO Brake Line Fitting Manual

Thank you for deciding to purchase a set of HALO brake lines for your car. Because you take your vehicles performance seriously - we only supply serious performance products. Please take a few minutes to read the following information on the fitment of the product. If you require any further assistance or advice please feel free to contact our technical department in the UK on 01246 281 543, or email us at

Our Brake Lines are manufactured from the finest quality stainless steel fittings swaged directly onto a hard drawn tensile stainless steel braided ptfe hose. This eliminates that 'spongy' feeling often with rubber hoses underneath extreme braking conditions - when you need their performance the most. The stainless steel exterior provides excellent resistance to both corrosion and abrasion. Our swaged fittings give a streamlined finish and a secure connection. Please examine the kit before installation to check that you are familiar with how the new set replaces the original hoses on your vehicle. 

Carefully remove the existing brake lines from the car - avoid splashing the paintwork with brake fluid. Remove all of the old washers and drain the system of brake fluid. Ensure all sealing surfaces are clean and in good condition.

Fit the enclosed HALO brake line kit using the new copper washers supplied.

Check the pitch of the any new banjo bolts supplied in our kit with those been replaced on your vehicle.

Check that all end fittings are securely attached to each line.

Check line(s) for clearance and that the kit has been installed without any kinks or twists in the system but do not fully tighten at this stage.

Make sure that any brackets or rubber retaining bushes are secure and that the hoses sits within them in the same position as with the OEM hose.

Check each brake line does not foul any suspension or steering components at full travel and then fully tighten all fittings and / or bolts in the following order : calliper fitting first followed by chassis fitting. It is always better to turn any fitting which has remained on the car rather than a fitting on the flexible hose as this will ensure no torsional force is applied to the new hose

Bolts should be tightened to the correct torque settings:

Stainless steel banjo bolts - Min 19 N m - Max 32 N m

Check line(s) again for clearance and that the kit has been installed without any kinks or twists in the system. No torsional force should be shown along the length of the hose.

Hoses with brackets / locators :

Calliper to bracket / locator - These two points move in relation to one another. If the hose is slack this side then the hose will be tighter the other side where movement does not need to take place.

Bracket to female / male - This part of the hose is subject to movement. Each end moves independently to the other. This side of the bracket needs the maximum amount of free hose as if the hose does not have enough slack length then during full lock or travel this hose is 'pulled' at the connector. This will mean that the stress is transferred to the sharpest point between the hose and fitting ( the ferrule ) which over time could result in a hole or hose being cut.

Double flare seatings - Halo use their own dual flare seatings in most of their male and female fittings. This was created so that the end user would not be able to use the wrong seating on their hose. As the pipe or hose which connects to our stainless steel fittings would be an OEM mild steel or brass fitting the dual seat deforms the softer OEM fitting to provide the perfect seal.

If your hoses have line locators on them you will find OEM line locator clips included. Place and tighten these clips approximately 1cm either side of the locator once it is in its correct position on the hose. It is crucial that you use the OE hose you are removing to note exactly where the line locator should and that the correct amount of hose is apportioned either side of the line locator. Failure to do this will result in the hose rubbing on any moving parts such as the shock, hub or suspension arms. Furthermore if the locator isn't placed in the correct position on the hose this could also lead to it becoming unsafely over-stretched in one direction.

Bleed the brake system in accordance with the manufacturers guidelines using fresh brake fluid.

Warning - Before driving ensure all brake connections are tight and free of leaks. The brake pedal should feel firm under pressure.

Thank you for choosing to purchase HALO brake lines.
