Stock S197 Mustang GT brakes fade fast once you push past street speeds, and bolting on a front-only big brake kit just shifts the imbalance instead of fixing it. EBC Racing's BBK016YEL-1 Apollo-4 Yellow Big Brake Kit addresses both problems at once, replacing the front calipers and rotors while simultaneously upgrading the rear friction and lines for a fully balanced, track-capable braking system.
Apollo-4 four-piston calipers in signature yellow. Machined from aerospace-grade billet aluminum and assembled entirely in the United Kingdom, the Apollo-4 calipers bolt to purpose-built brackets that position the larger 355mm rotors without clocking or shimming. Every metal caliper fitting and rotor drive bobbin uses stainless steel construction to resist corrosion across seasons and track days.
355mm rotors sized for serious heat management. The larger swept area moves heat away from the pad face more efficiently than the OEM rotor, pushing the threshold for brake fade significantly further down a long straight or repeated braking zones. The disc bell is machined from the same aerospace-grade billet aluminum as the caliper brackets, keeping unsprung rotating mass in check.
Yellowstuff pads front and rear. EBC's Yellowstuff compound is their flagship fast-street and track formulation. The front pads bed into the new Apollo calipers, while a matched set of rear Yellowstuff pads fits the factory caliper, so both axles generate consistent friction force through the same temperature window.
Balanced is Better, not just bigger. Every EBC kit ships with braided stainless brake lines for both the front and rear axles. A firmer pedal means nothing if one end of the car locks before the other; the rear line upgrade and rear pad upgrade close that gap without requiring a separate purchase or a second installation session.
Complete hardware included. Every bleed nipple, bracket bolt, and fitting comes in the box, so no hardware-store runs are needed. The kit replaces all equivalent stock components on the front axle and supplies everything the rear needs to match.
Product Benefits
