Audi A3 and S3 8L Front Caliper Conversion Brake Lines HEL Stainless Steel Braided
HEL part number CALCONV-001
Product details
This brake line kit is assembled in-house and machine-crimped onto stainless steel braided hose, matching the standard brake hoses exactly. Each kit ships complete, so installation is straightforward.
If your setup differs from standard fitment, for example with upgraded or aftermarket calipers, tell us which calipers you are fitting and we will spec the lines. Knowing the fitting type helps, but is not essential.
What are the Benefits?
- Firmer, more consistent brake pedal feel
Rubber brake hoses swell under pressure, particularly during hard braking, which produces a soft and inconsistent pedal feel. HEL's braided hoses use a 3-layer construction designed to handle high pressures and temperatures, improving brake response, modulation and control. Rubber hoses typically need replacing after around 5 years; HEL states its braided lines are built to outlast that lifespan.
- Strong resistance to abrasion and wear
HEL builds every brake hose fitting in-house from 303/304 grade stainless steel. Inside each braided hose is a PTFE core, valued for its chemical resistance and tolerance of extreme temperatures; unlike rubber, it will not perish or crack with age. A stainless steel overbraid reinforces the PTFE core against wear, and a wipe-clean PVC outer layer (clear or coloured) keeps the hose tidy and protects paintwork from scratches.
HEL controls every stage of manufacturing in-house, which gives confidence in consistent quality; brake hoses are tested extensively in the lab and on the track.
- Custom colours for a personalised look
Hose covers come in a range of colours so a brake line kit can match a chosen colour scheme, plain black for an OEM appearance, or a bolder colour to stand out.
- A distinctive HEL hose-fitting and ferrule design
Each HEL brake line fitting has an internal multi-groove design. During assembly, the fitting and ferrule get swaged onto the hose. From there, its PTFE core is forced into three internal grooves that double as sealing o-rings and let the fitting turn freely yet securely after swaging. This keeps the hose sound while letting installers rotate the fitting in place to dial in the fitment. Inside the ferrule, a locking groove engages a channel on the fitting so that, once swaged, the fitting cannot come away from the hose.
