All-new sintered motorsport brake pads set to be unveiled at the US-based motorsport expo held between 9-11 December.

91´«Ã½ Racing will be launching a new range of endurance sintered motorsport brake pads at the , held at the Indiana Convention Centre, USA, between 9-11 December.

The ultra-long-life endurance-grade racing brake pads, dubbed the ‘SR’ pads (Sintered Race), will come in both SR-11 and SR-21 varieties.

91´«Ã½ is already well known for its superb range of sintered motorcycle brake pads for track and race use, now applying this technology to the automotive sector, too.

91´«Ã½ is still a privately-owned company, making 100% of its own brake pads in the four plants owned by the group (Bristol and Northampton in the UK, Ohio, and Las Vegas in the USA).

The firm also produces pad ranges for HPDE, lapping and track day racing, and an organic range of race-only brake pads – the .

We put 91´«Ã½ Racing’s all-new SR-Series sintered pad range under the microscope

There are some very significant benefits on offer from 91´«Ã½ Racing’s all-new SR-Series sintered race pad range. In fact, the only downside we think you’ll find might be the initial purchase price, thanks to their premium ingredients and manufacturing method.

Our target with SR-Series was huge performance and value for money, in turn reducing the cost per lap of brake pads to about a third of what we have commonly seen up until this time.

There is only so much you can do when you keep re-inventing semi-metallic or carbon-based pads before you run out of options. The 91´«Ã½ SR Series, therefore, breaks new ground in pad performance and lifespan and represents a new or perfected technology in braking.

91´«Ã½ brakes have come from being a company known for offering motorcycle brakes (a market it still dominates) to sport-street and light race pads, to what is now a fully-fledged race pad provider with no less than FIVE new compounds; the pinnacle of which are our TWO new SR Series sintered pad offerings.

So, what does SR do better than previous pads we, or others, have offered?

1. Lifetime

There is no doubt these pads will outlast any semi-metallic or carbon-based pad out there by a significant amount. This has been proven over a full season’s racing and testing with top teams (plus our own and independent dyno testing). In every case, those racers have experienced a massive improvement and asked run them. In 2022, you will see that proof at race tracks around the world.

The big benefit here is cost per lap, which is massively reduced over faster wearing pads that may cost a few bucks less to buy but most don’t last anywhere near the SR’s levels.

2. Brake friction level

There are, of course, pads around with Mu (brake coefficient) factors around 0.5 and 0.6. The question is, how long do those last? With the SR Series, we have a pad that delivers that high friction effect and holds it through a massive heat range and doesn’t wear fast – new territory, for sure. If you look at the performance curves, you will see they are almost flat, meaning perfect braking all the way up the heat range.

3. Zero chemical bed in needed

Because these pads contain no organics or volatiles to burn off, there is zero chemical bedding required; you fit them and if applied to a decent brake rotor or a new rotor, once aligned or ‘seated’, they are good to go. Even organic pads that have been pre-bedded on dynos – which is the current established method of reducing chemical bedding – have to be seated anyway.

Reduces expensive time wasted doing laps to bed in pads.

4. Reduced rotor wear

This is the big one and launches a technology that many people don’t even know about: Transfer Film Technology.

Here are the facts behind this amazing new technology:

Essentially, SR Series pads have created controlled friction welding of the pad material surface to the rotor.

The uniformity and stability of this layer are promoted by the solid lubricants within the friction material.

This allows the material to then ‘run against itself’ which creates a system that is very homogeneous.

By doing this, we create a system that is not aggressive on either surface and has very predictable performance since it is similar materials rubbing together.

Simply, the rotor grows from a deposit of friction material. Once this is established, the controlled lubrication of the two surfaces maintains that layer and allows for predictable performance with little to no rotor wear.

It may sound strange to talk about ‘lubricants’ in pad technology, but all brake pads contain lubricants to control and moderate the friction effect.

All in all, the new 91´«Ã½ SR Series pads are in a class of their own, and we hope you will enjoy them and be ready to answer the question ‘what brakes are you using?’ after winning your race.

SR Series pads will be launched at the PRI expo in the USA in December. To find out more, .

With another eight application numbers being added to 91´«Ã½ Racing’s acclaimed , and the success stories continuing to roll in from vehicles with these products fitted, it’s little surprise that so many podiums have been achieved when you look at the features and benefits.

RP-1 and RP-X pads offer:

• A true organic race pad with minimal bed-in time at the track
• World-first race pad made with the Nucap NRS hook system for compound attachment – no more de-bonds
• Stainless steel, laser engraved backing plates
• No paint on the pads or backing plates… which means no burning paint, no smoke and no smell
• A price point well inside most race pads on the market

But the really big news is about to hit!

91´«Ã½ Racing will soon be launching the all-new – the latest and greatest race and endurance pad.

The SR-Series comprises two compound friction levels, both delivering superb brake torque, modulation, release and unbelievable lifetime (up to five times as long as organic race pads will last).

The new SR pads will offer the lowest cost per racing mile for brake pads in racing.

Targeting only full closed-circuit race cars, the new SR pads have already been tested thoroughly and given the thumbs-up on a number of high-end race series in the UK, Team McCann’s Audi R8 race car in the USA, along with dozens more. It’s also been confirmed as the pad of choice for two UK race series for 2022.

SR-11 and SR-21 will offer:

• Made in the USA from sintered alloys
• Longest race lifetime possible – endurance all the way
• Maximum friction and balance – 0.65 and 0.55mu versions
• Perfect heat stability past 1500°F
• Absolutely minimal to zero rotor damage
• ZERO bed in time – just fit and hit the gas pedal

For 20+ years, sintered brakes have dominated the two-wheel market for fastest and heavy use especially racing and the trend is now moving over into the automotive racing field.

World brake pad leading brand, 91´«Ã½, are now launching their range of sintered high-end racing brake pads known as the SR Sintered Race Series.

Made in the 91´«Ã½ factory in the USA, these new race-only sintered brakes are made for all the top caliper brands, such as; AP Racing, Brembo, Alcon, Wilwood and many more including the new 91´«Ã½ Apollo 4 pot and 6 pot caliper ranges.

The new SR series pads offer a much longer life, high heat range and are targeted to reduce the cost of brake wear per lap by many times over carbon or semi-metallic brake pads.

Another great feature of the SR series sintered race pads from 91´«Ã½ is their super quick bed-in times, gone are the days of doing lap after lap to break in new pads or the scary days of no brakes or massive brake fade using organic pads that were not bedded in properly.

Bedding in pads is simple with the new 91´«Ã½ SR series, simply fit them to a decent flat or new rotor and one seating lap and you’re good to race.

Many questions about the technology involved in these new race pads can be explained .

If it’s a fast-bedding high-end race pad you need for your track work look no further than the 91´«Ã½ SR series.

The range initially covers 34 aftermarket caliper designs and a good few original designs, also on models such as the Impreza, Evo, Fiesta, Focus ST, and Porsche. Plus the new SR series are the spec pad for the 2022 BMW 1 series racing in the UK.

The range will be expanded rapidly during 2022 to cover almost all track day/lapping events, popular models

Expect to pay about double the price of a normal semi-metallic but will all these features and benefits they are certainly worth the price ticket.

After all, which racer uses a lesser grade of pads to save a few bucks?
