Once you have found the leaky hose, replace it or consider replacing all brake hoses. If one is leaking, there is a good chance all brake lines are leaking.

However, take accurate measurements before you start.

Add your stainless steel braided brake lines to the shopping cart. Repeat the process until your cart is full of braided hoses.

Then select your brass fitting for your Hydrastar or Al-ko IQ7.

The image on the right is what your stainless braided hydraulic kit should look like once added to the shopping cart.

Customers have been asking for different lengths of braided hoses, so the tandem kit wasn’t practical.

Yes, we listened to you, and I can now present this auto-build kit to ensure the exact size for your hydraulic line installation.

Each hose is stamped with SAE (Society of Automotive Engineers) compliance.


Adaptors and Brass Tees

After selecting your stainless braided line, add the adapters and the stainless braided line to your shopping cart until your takeoff sheet is fully ticked and the items are ready for purchase.

The next big decision is how fast you want your gear.

You can select from Express Services to eParcel.

Older trailers use flexible rubber brake hoses on their hydraulic braking systems. The rubber hose has either a male-to-male or a male-to-female end.

Product FAQ & Installation Guide

Stainless Steel Braided Hydraulic Brake Hoses

The Do’s (Best Practices)

  • Do verify fitment: Ensure the hose length and fitting types exactly match your vehicle’s make, model, and year before starting installation.
  • Do use new washers: Always install fresh copper crush washers on both sides of the banjo fittings to guarantee a leak-free seal.
  • Do check clearance: Turn your steering lock-to-lock and cycle the suspension fully to confirm the hose doesn’t stretch or rub against tires and chassis parts.
  • Do bleed thoroughly: Perform a complete brake fluid bleed sequence after installation to remove all trapped air from the hydraulic lines.
  • Do use a torque wrench: Tighten all banjo bolts and line fittings to the exact manufacturer-recommended torque specifications.

The Don’ts (Things to Avoid)

  • Don’t twist the hose: Never install the hose with a twist or kink, as this stresses the internal Teflon core and braided jacket.
  • Don’t reuse old hardware: Never reuse worn crush washers or corroded banjo bolts, as they are prone to high-pressure leaks.
  • Don’t over-tighten: Avoid over-torquing fittings, which can strip threads, crack banjo bolts, or crush the sealing washers excessively.
  • Don’t allow sharp bends: Avoid routing the hose around sharp edges or forcing it into tight radii that violate the minimal bend limits.
  • Don’t drive before testing: Never operate the vehicle on public roads until you have confirmed a firm brake pedal and verified there are zero fluid leaks.
