HEL Performance MAZ-4-124 4-Line Braided Brake Line Kit
HEL Performance braided brake line kit for Mazda MX-5 Mk4 / ND and RF models fitted with the factory front Brembo brake upgrade as listed in the compatibility table.
MAZ-4-124 is the Brembo-specific MX-5 ND brake hose kit and contains four braided hydraulic brake lines covering the front and rear of the vehicle. It is designed to replace the flexible brake hoses on cars equipped with Mazda's factory Brembo front-brake package.
HEL Performance brake hoses use a PTFE inner core reinforced by stainless-steel braid with a protective outer covering and stainless-steel fittings. This reinforced construction is designed to minimise hose expansion as hydraulic pressure increases, helping provide a firmer and more consistent brake-pedal response.
Braided brake hoses are commonly fitted when the original flexible hoses have deteriorated with age or as part of a brake-system refresh or performance upgrade. This MAZ-4-124 kit is specifically configured for the factory Brembo front braking system and should not be confused with the MAZ-4-119 kit used on standard non-Brembo MX-5 ND applications.

Fitment advice: MAZ-4-124 is designed specifically for Mazda MX-5 ND / RF models fitted with the factory front Brembo brake upgrade. Cars retaining the standard non-Brembo front brakes require the alternative HEL Performance MAZ-4-119 kit. For imported, modified or previously repaired cars, matching the braking-system layout and hose kit reference is recommended before ordering.
Other items to consider: When changing the brake hoses you may also want to consider purchasing fresh brake fluid, replacement bleed nipples where required, brake cleaner and any related brake components showing signs of corrosion or wear.
Useful tools / consumables: Brake pipe spanners, suitable brake fluid, brake bleeding equipment, brake cleaner, protective gloves, axle stands and normal workshop hand tools are useful when carrying out this job.
Difficulty guide: DIY Difficulty: Moderate / Advanced. Replacement requires opening the vehicle's hydraulic braking system, correctly routing and securing each hose and thoroughly bleeding the system afterwards. A firm brake pedal and leak-free hydraulic system should be confirmed before the vehicle is driven.
Why HEL Performance? HEL Performance braided brake lines are designed for drivers and workshops looking for a durable hydraulic hose upgrade with a firmer, more consistent brake-pedal feel and improved resistance to hose expansion compared with ageing conventional flexible brake hoses. Their PTFE-core, stainless-steel braided construction and stainless-steel fittings make them well suited to road, fast-road and track-day MX-5 preparation.
What’s in the box: 1 complete HEL Performance MAZ-4-124 kit containing 4 braided brake lines for the front and rear of the vehicle. Stainless-steel banjo bolts and copper sealing washers are supplied where required by the individual hose configuration, together with installation information.
Installation / bleeding notes: The brake hydraulic system must be bled after installation. Each hose should be routed without twisting and must remain clear of wheels, suspension and bodywork throughout the full steering and suspension range. Use the correct brake fluid for the vehicle and carefully check all hydraulic connections for leaks before use.
