Stock braking systems on the Focus ST MK2 were never intended for sustained hard driving, and heat soak and fade arrive quickly when you push them at the track. The EBC Racing BBK011YEL-1 Yellow Apollo-4 Big Brake Kit replaces the entire front braking system with purpose-built, track-capable hardware and backs it up with matching rear friction pads and braided lines for a fully balanced upgrade across both axles.
Balanced braking, not just bigger braking. Unlike front-only kits that leave a mismatched rear axle, this kit ships with EBC Yellowstuff friction pads for the rear original calipers and braided stainless brake lines for both front and rear. The result is a consistent, predictable pedal feel that holds up under repeated hard stops without pulling, fading, or fighting itself.
Apollo-4 calipers built from the ground up in the UK. Cast, machined, painted, and assembled in Britain, the Apollo-4 four-piston calipers clamp 330mm rotors at the front. Every metal caliper fitting and disc drive bobbin is stainless steel to resist corrosion, while the caliper brackets and disc bells are machined from aerospace-grade billet aluminum for strength without unnecessary mass.
Yellowstuff pads included front and rear. EBC's Yellowstuff compound is the pad of choice across the kit, rated for fast street and track use. The compound reaches operating temperature quickly, bites hard from a cold stop, and maintains consistent friction through extended sessions where conventional pads begin to fade.
Every piece of hardware is in the box. No sourcing additional bolts, bleed nipples, or brackets. The kit ships complete with everything needed to fully replace all equivalent stock components, so installation is straightforward and nothing is left half-done.
Product Benefits
- Balanced Full-Vehicle Upgrade: Front 330mm rotors and Apollo-4 calipers paired with rear Yellowstuff pads and braided lines for a matched system.
- Apollo-4 Four-Piston Calipers: Cast, machined, and assembled in the UK with stainless steel fittings throughout.
- 330mm Front Rotors: Larger swept area dissipates heat faster and delays the onset of brake fade.
- Aerospace Billet Aluminum: Caliper brackets and disc bells machined from high-strength aluminum alloy.
- Yellowstuff Compound: EBC's flagship fast-street and track pad included front and rear for consistent friction across the full system.
- Braided Stainless Lines: Front and rear lines reduce expansion under pressure for a firmer, more responsive pedal.
- Stainless Steel Hardware: Every bobbin, fitting, and bleed nipple resists corrosion for long service life.
- Complete Kit: All hardware included to fully replace equivalent stock components with no additional parts required.
- Fitment: Front axle upgrade for the Focus ST MK2.
