Self-adjusting brake cable for EV applications

Self-Adjusting Drum Brake Cables (Inside the Drum)

We manufacture the inside-the-drum self-adjuster cable that indexes the star wheel—independent of how the brake is applied (parking cable or in-drum EPB). We build by dimensions and targets: overall length, free cable length, terminal geometry, spring details, environment, and life-cycle.

One-sentence explainer: Actuation moves the shoes; the self-adjuster keeps them set. Our cable is the internal link that indexes the star wheel during apply/release cycles.

Why EVs Choose Drum Brakes & Self-Adjusting Cables

Why Drum Brakes on EVs

Perfect for regenerative braking duty cycles
KEY INSIGHT

Regen does the heavy lifting → friction brakes work less

DRUM BRAKE ADVANTAGES
  • Enclosed design - Natural corrosion protection
  • Low residual drag - Maximizes EV range
  • 150,000 km intervals - Continental's VW ID series
REGULATORY DRIVER

Euro 7 brake dust limits:

  • 7 mg/km (2025) → 3 mg/km (2035 BEVs)
  • Enclosed drums contain particulates

Why Self-Adjusting Cables

Internal star wheel actuator advantages
CORE FUNCTION

Lever + star wheel maintain shoe-to-drum clearance

CABLE ADVANTAGES
  • Tunable drag - Every watt matters on EVs
  • Packaging flex - Tolerance stackup friendly
  • Corrosion proof - 304/316 stainless, coated
  • Fast iteration - Length/terminal tweaks vs retooling
OUR APPROACH

Dimension-driven manufacturing:

  • OAL + free length + terminal geometry
  • Spring details + environment + lifecycle

THE COMBINATION

Regen-friendly drums + precision cable adjusters = Lower maintenance, contained particulates, optimized EV range

EV Brake Cable Engineering FAQ

Most current EVs do not use cable-actuated drum brake systems. However, we provide co-development services for engineering teams exploring this technology for future applications where cables might offer advantages in packaging, cost, or reliability.

Cable systems could offer low rolling resistance for energy efficiency, corrosion resistance with infrequent brake usage, packaging flexibility compared to motor-in-drum EPB systems, and potentially lower costs in high-volume production.

Provide envelope constraints (OAL/free length windows), terminal requirements, operating environment, drag force targets, and lifecycle expectations. Our Tesla-trained engineers will work with your team to optimize the design.

Yes. Drum architectures use a mechanical automatic adjuster (lever + star wheel; some add thermal compensation) to maintain shoe clearance.

No—the self-adjuster cable is inside the drum and only drives the adjuster mechanism; the parking brake actuation (cable or EPB motor) is separate. RIK can also supply parking brake cables—please contact us for more information.
