EBC 355mm Front Big Brake Kit For F30/F31/F34 BMW 3-Series - Yellow Apollo 4 Calipers

Every individual component found in a Balanced Big Brake Kit has been designed from the ground up to perform, right down to the very last bleed nipple. Every single brake caliper metal fitting and brake disc drive bobbin is manufactured from stainless steel to ensure parts are long lasting and do not corrode.

The brake disc bell and caliper brackets are machined from aerospace grade billet aluminium for high strength and durability. To finish off, every kit is supplied with EBC’s flagship fast street and track Yellowstuff™ brake pads.

Why Apollo Calipers?

Apollo brake calipers utilise a 2-piece bolted design, incorporating high tensile 12.9 grade steel bolts for reinforcement of the caliper bridge section. Computer FEA analysis shows that the utilisation of high-tensile steel bolts to reinforce the bridge brings significant improvements in caliper stiffness compared to a mono-block design. A stiffer bridge section means less elongation during brake apply, giving a firmer and more responsive pedal feel, especially after a period of harder braking where the aluminium bridge of a mono-block design caliper softens appreciably with increasing temperature.Unlike the vast majority of cast calipers, which are typically gravity cast, Apollo Series caliper bodies are machined from heat treated low pressure castings. Low pressure casting is a vastly more expensive production method than conventional gravity casting, but by forcing the aluminium alloy into the mould under pressure the consistency of the finished part is greatly improved.

This gives EBC’s Apollo Series brake calipers a noticeable performance advantage over conventional gravity cast calipers, exhibiting higher overall strength and a comparable caliper body stiffness to forging. Unlike most painted calipers on the market, Apollo brake calipers are not painted using a powder coat finish. Powder coat cracks and discolours with exposure to high heat, meaning that powder coated calipers look great out the box, but the colour quickly fades away in use. We don’t just want Apollo calipers to look good in the box, we want them to look great for years to come, that’s why EBC finish every caliper using our advanced high-temperature Teflon™ polyester coating process. This top-coat paint system is similar to what’s used in the cookware market on the underside of pans and it gives a durable, fade resistant coating that’s easy to wipe clean and ensures that Apollo calipers will look great for years to come.

YellowStuff Pads

Compound has an extremely low metal content, meaning these pads are very kind on discs and any brake dust can be easily wiped off painted wheels and calipers with a damp cloth. Yellowstuff™ pads will not eat through rotors like most other performance pads on the market, where some users report a wear ration of 1 set of pads to 1 set of discs! Although not a legal requirement for brake caliper conversions, Yellowstuff™ material is ECE R90 approved giving you peace of mind that these pads will operate safely in all climates, at any vehicle speed and in all weather conditions.
 

Floating Brake Rotors

• Fully floating 2-piece rotor that allows outer ring to expand freely in response to heat. This reduces stress which in turn extends rotor life and reduces the tendency for rotor cracking during extreme use.
• Drive bobbins machined from a single piece of stainless steel giving maximum strength and corrosion resistance. Stainless bobbins reduce the requirement for regular disc maintenance and ensures the outer ring continues to float freely even when used on the public road with corrosive salts and other road grime.
• Each bobbin assembly features an anti-rattle spring clip ensuring silent operation when driving on the public highway. Rotor rings feature 48 directional internal curved vanes for improved rotor cooling

Friction Rings

• Friction rings are cast from high carbon G3500 alloy giving excellent wear properties and improved thermal capacity.
• All EBC disc rings are cast using the ‘centre split’ casting method, ensuring a balanced casting that will not distort under high heat, an issue common with cheaper ‘moulded out’ castings.
• Unique Swept Groove slot design for effective evacuation of braking dust and gasses whilst ensuring good initial ‘bite’ on brake apply
• Replacement disc rings for EBC floating rotors are significantly less expensive than our major competitors.
• EBC floating rotors are now enhanced with a Thermic Black anti-corrosive paint, which reduces corrosion and extends the life of the product.

Super Dot 4 Brake Fluid

Every kit is supplied with 1 litre of BF307+ super DOT 4 brake fluid. This fluid has a 307 degrees C boiling point, a significantly higher boiling point than standard DOT 5.1. Having such a high boiling point gives your braking system exceptional endurance, allowing you to push hard for extended periods without heat soak causing the fluid to boil and resulting in fade.

This DOT 4 fluid is compatible with all vehicles which use DOT 3, DOT 4 and DOT 5.1 fluid including vehicles fitted with ABS systems.
