We show you the 91��ý components that perfectly match your lifestyle

Welcome to EBC’s ‘Suit Your Style’ blog series, where we match you up with the 91��ý upgrades that complement particular driving requirements, ensuring you get the ideal components for your vehicle.

In today’s blog, we’re hitting the circuit to look at braking components for dedicated track/race cars – the most demanding form of driving where it’s more vital than ever to rely on strong and enduring stopping power.

Around a decade ago, 91��ý launched its high performance/motorsport sub-division, 91��ý Racing – a firm that has become synonymous with range-topping braking at race tracks around the globe.

From road-legal track upgrades to endurance race components, there’s something for every corner of the motorsport spectrum in the 91��ý Racing range, as we will explore below…

Bluestuff

A great all-round sport and race pad – just as comfortable on track as it is performing daily driving duties. Road legal in most territories, making it incredibly versatile.

Bluestuff material exhibits a 0.52μ stable friction once bedded, stable up to a slightly higher 550℃/1000℃ than its sister compound Yellowstuff but with the benefit of a 30% longer lifespan.

Bluestuff has been a track day favourite for years and is the spec pad for the BMW 318i Cup series throughout Europe. New formula is copper free to conform to upcoming environmental legislations.

RP-1/RP-X Motorsport Brake Pads

Designed for vehicles driven hard on track, RP-1 possesses a moderately high friction level of 0.45 between 100 – 750°C (200 – 1400°F). The more progressive response characteristic of RP-1 makes it well suited for inherently ‘over-servoed’ vehicles where a softer pad material is desirable to allow greater finesse when on the brakes.

RP-X possesses a high friction level of 0.55 between 0 – 750°C (Ambient – 1400°F) and achieves a 100% brake effect from cold – an excellent choice for sprint racing or hill climb events, where full brake performance is essential without requiring any ‘warming up’, but also makes RP-X well suited to any type of circuit use where a high initial bite and powerful brake response is desirable.

Both RP-series brake pad options are a fantastic choice for track day regulars or out-and-out racers.

Please note: EBC’s RP-series of brake pads are not designed for the road, but may be used in street conditions where local laws permit.

SR-11/ SR-21 Sintered Endurance Brake Pads

Whilst the competition struggles to make organic and semi-metallic pads last longer and longer to reach the pinnacle of brake pad durability, EBC has taken a fresh new approach with a blend of compressed and heat fused (sintered) metal powdered alloys, to deliver a brake pad that brakes better and lasts longer than just about everything.

The new SR series comes in two blends, SR-11 the medium friction version and SR-21 the higher friction options

Although badged an endurance-grade material, these pads are equally at home in any form of closed-circuit racing, short or long duration.

Please note: EBC’s SR-series of brake pads are not designed for the road, but may be used in street conditions where local laws permit.

Fully Floating Two-Piece Brake Rotors

Craftsmanship meets fine materials in EBC’s highest performing rotor to date. Not simply a ‘bolt-up’ two-piece unit like many of EBC’s competitors offer, they are genuine fully floating units with flat-sided SD square drive buttons, allowing expansion and contraction under the harsh conditions of heavy braking.

Featuring a a black, heat-resistant finish that quickly wears down to the natural iron finish on the disc ring within the first few miles. Any unswept areas remain protected by the black coating, such as the outer edges and inside the pad track, unless burned off due to hard use and high temperatures.

Another major benefit of the 91��ý fine slotted discs is their ability to totally resist cracking common with ‘through-drilled’ discs.

Apollo-Series Brake Calipers

UK designed and made strong-yet-lightweight aluminium four- and six-piston brake calipers, which can be purchased within a Big Brake Kit or as separate components for vehicle builders to convert cars where a dedicated Big Brake Kit is not yet made by EBC.

Packed with cutting-edge tech such as high-temperature fluid seals coupled with full boot type dust seals, lightweight hard-anodised aluminium pistons, staggered piston sizes and fully stainless-steel fittings.

BF307+ Super DOT 4 Brake Fluid

EBC’s BF307+ high performance Super DOT 4 brake fluid has been specially formulated to provide outstanding performance for braking systems routinely operated at extreme temperatures, making this fluid ideal for fast street use, track days and racing.

Know Your Stuff – Technical Braking Q&A

ebcbrakes2021 — Thu, 22 Jul 2021 12:34:06 +0000

We answer some of the most frequently asked questions from the world of performance braking

You probably don’t need us to tell you that there are often a large number of myths and debates revolving around the world of vehicle braking. In this article, we aim to answer some of these queries once and for all…

Q) How often should brake fluid be changed?
A) Every two years for normal road use, or every 2-3 visits to the race track for a vehicle used frequently on the circuit.
Q) How do I choose the right type of brake fluid?A) Most vehicles use Glycol DOT 3 or DOT 4 fluid – see the top of your master cylinder or owner’s manual for more info.
Q) What’s the difference between DOT 3/4/5 brake fluids?
A) DOT 3 and 4 are effectively the same, with DOT 4 being purer. DOT 5 can be silicone or glycol variants and cannot be interchanged with DOT 3/4.
Q) What type of brake fluid is used for racing?A) A DOT 4 high-temperature version is best, such as .
Q) What is ‘dry boiling point’ and ‘wet boiling point’?A) The dry boiling point refers to when fluid is new from an unopened bottle. The wet boiling point is when the fluid is used and needs changing (where the water content is past 3%).
Q) Why is dry boiling point higher than wet boiling point?A) This is because the moisture content of a brake fluid boils at a lower temperature, therefore the wet boiling point will be lower.

Q) What are brake caliper seals made of?A) Most vehicles use EPDM rubber, while a few use Nitrile rubber. A third, rarer version is Viton.
Q) How often should brake caliper seals be changed?A) Every 2-3 years in road use, or every few races on the track, or if the caliper body reaches temperatures over 250°C.
Q) What is the maximum safe temperature for caliper seals to be exposed to?A) EPDM seals (the most popular type) are not designed for use above 140-150°C, which corresponds to a caliper body temperature of about 250°C.

Q) How hot do my discs/rotors get and what does this mean for my pad compound selection?A) Heat paints are a handy tool in telling you exactly what products you should be using.

91��ý offers three heat paints which can be brushed onto the outer edge of the rotor before racing, to detect temperatures. The 91��ý rotor paint kit also includes 10 caliper heat strips.

The rotor paints supplied are:

#1 – 800°F/430°C

#2 – 1000°F/540°C

#3 – 1200°F/650°C

Paint all three separately in lines on your disc/rotor edge.

The temperature at the centre of the brake pad will always be on average 100°C/200°F more than the outer edge of the rotor in race use. If your rotor edge is not setting off the 430°C paint line, all EBC compounds will be fine.

If the 430°C paint line activates (530°C at the centre of the pad), you’re at the limits of .

If the disc/rotor outer edge temperatures exceed 540°C (640°C approx. at the pad centre), you are past the limits of EBC’s Bluestuff and need to switch to .

If the 650°C paint line goes off (750°C at the pad centre), you’re definitely in need of either the RP range or SR series of pads.

Here is a guide on 91��ý compounds and their temperature ranges:

(The curves below show that on average in race use, the pad temperature runs at approx. 100°C above the disc/rotor outer edge:)

Only the best for you and your car.
