Stock brakes on the Focus ST MK3 were built for commuting with occasional spirited driving, not sustained track sessions or repeated hard stops. The EBC Racing Yellow Apollo-4 Big Brake Kit replaces the entire front braking system with a 355mm rotor and four-piston Apollo caliper setup, then balances the upgrade with matching rear friction pads and braided lines for both axles.
A truly balanced brake upgrade. Most big brake kits stop at one axle, leaving the rear system to limit the performance gain. Every EBC Balanced Big Brake Kit includes matching Yellowstuff rear pads for the factory caliper and braided stainless brake lines front and rear, so the entire hydraulic and friction system moves forward together. The result is a firmer pedal, shorter stops, and consistent feel across the full brake bias.
Apollo-4 calipers built in the UK. The Apollo Series calipers are cast, machined, painted, and assembled in the United Kingdom from aerospace-grade billet aluminum brackets. Every metal caliper fitting and disc drive bobbin is stainless steel to resist corrosion over years of hard use. The yellow finish is a factory applied coat, not a rattle-can afterthought.
Yellowstuff pads front and rear. EBC's Yellowstuff compound is the flagship fast-street and track pad formulation. It bites early, resists fade under repeated heavy braking, and remains driveable in daily traffic without the cold-bite issues common to race-only compounds.
Complete hardware included. Every bleed nipple, bracket bolt, and fitting needed to replace all equivalent OEM components ships in the kit. Nothing needs to be sourced separately before the install can begin.
