EBC BC4103RED-R Apollo-4 4-Piston Red Caliper Passenger Front for 2013-2018 Ford

Vehicle Fitment

• 2013-2018 Ford Focus ST (Mk3 2.0L Turbo, Front Passenger Side, Apollo-4)

Fitment Notes

• Caliper is Front Passenger (right side driving-side) position only.
• Requires wheels that provide sufficient clearance for the larger caliper.
• Brake line routing must match OE or be adapted; use correct banjo bolts and seals.

Features

• Fixed 4-piston aluminium Apollo-4 design for improved stiffness and braking control. 
• Two-piece bolted bridge section with 12.9-grade high tensile steel bolts for added rigidity.
• Painted in Racing Red with high-temperature Teflon-polyester coating that resists fading and heat damage. 
• Aluminium material keeps weight down, improves heat dissipation over cast iron. 
• Piston sizes staggered (38.1 / 41.2 mm approx) for even pad wear and improved modulation. 
• Max working pressure rated at ~140 bar. 
• OE replacement quality - intended to replace equivalent factory parts for proper fitment. 
• Wide application across many years and trims of the Focus ST, good for upgrades or replacements.

Product Description

The **EBC BC4103RED-R** is a high-quality performance brake caliper designed for the **2013-2018 Ford Focus ST** (Mk3, 2.0L Turbo), specifically for the front passenger (right) side. This Apollo-4 model uses a fixed 4-piston configuration, with a lightweight aluminium body and advanced coatings to maintain performance and appearance even under aggressive driving conditions. With staggered piston sizes, you get even pressure distribution and consistent pad wear. The bolted bridge design with high-tensile steel adds stiffness over OE castings, giving better pedal feel and reducing flex during high brake loads.

When replacing or upgrading, ensure your wheel and brake hardware setup allow the larger caliper to clear the wheel's inner barrel. Also verify hose routing and line fittings match the OE setup. This item is a direct replacement for the front passenger side only - for optimal braking balance, replacement of the driver (left) side is recommended as well.
