S4 Brake Kits with Redstuff Brake Pads Features

About Slotted Rotors

• All EBC rotors including USR Slotted Rotors are British made and are precision machined in the UK. Rotors are made from high quality grey iron to exacting standards and undergo extensive testing and rigorous quality control. Slotted rotors can significantly improve brake performance and longevity when used with a matching high friction brake pad set. Having sold hundreds of thousands of brake kits EBC Brakes feel confident their approach is as perfect as it gets.

• EBC is of the opinion that slotted rotors have been “Over sold” by certain marketplace participants and their findings are that a slotted rotor will only give benefits if used with a pad that compensates for its reduced surface area.

Ultra Quiet Slotted Brake Rotors

• Manufactured using premium disc blanks mentioned above, the narrower multi slot design of the Ultimax sport rotor and the progressive angle at which the slots are machined creates a quiet running sport rotor that still has benefits of removing gas, dirt, water and debris and maintaining parallel pad wear.

• EBC have always been honest enough to say that the biggest advantage of slotted rotors is the fact that they promote flat and parallel pad wear rather than allowing ridges to develop on pads and rotors which is typical of “drilled only” sport rotors. By preventing these ridges brakes stay more consistent throughout pad and rotor wear life (simple physics!).

Why Slotted! The Benefit?

• The benefits of degassing and promoting flat and smooth pad wear are a clear plus in favour of sport rotors but the trick is to opt for a matched set of brakes and not to just expect a slotted rotor to improve braking on its own. . When used with higher friction EBC Redstuff, Greenstuff or Yellowstuff brake pads these rotors will deliver better brakes.

• The different slot pattern of the EBC USR Series has made this range a popular choice for drivers who desire improved sport braking with minimal air noise from the slots. The finer slot pattern is what makes these sport rotors more silent in operation whilst still offering pad degassing and removing dirt dust water and debris from the braking area.

Statement Of Quality

Geometry Issues

One in seven cars suffers geometry problems during its life that can affect steering and cause brake vibration. These are not a product quality issue. These can happen by simply nudging a kerb or by driving over a pothole. EBC is not alone in recognising this problem but is the only brake supplier on the planet prepared to offer diagnosis and a solution.

Installation or hub run-out issues

These cause what is known as DTY. The videos below show how to correct for brake vibration caused by DTY (disc thickness variation). DTY develops in a car after 3000-4000 miles caused by runout built in to the car or due to incorrect alignment of the rotors at install. This is quite a common fault on modern cars and many cars require this at every rotor change. Drivers also confuse hub distortion with a rotor quality issue but in 99% of cases the DTY is a car problem, not a rotor quality problem. You can replace the rotors as many times as you like trying to solve vibration and the problem will only go away for a few thousand miles and then return. This means you have purchased new rotors in good faith but the problem is not solved and will not go away permanently until you perform this procedure. After this skimming of the rotor surface you will have smooth brakes , more effective brakes and zero vibration. It is even a very worthwhile practice when fitting new rotors to have all four rotors skimmed into perfect alignment on your car with this inexpensive procedure. Rotor distortion due to DTY is very common, in fact one in seven cars has a steering geometry problem either when it is built new or after nudging a kerb or hitting a large pothole. Uneducated people still say “my rotors are warped”. Well the engineering facts are rotors do not warp, they are made of cast iron, they are very tough and can be run to red heat and cooled time after time and they will not distort, we do this day in day out on our Dynos in the EBC lab. Thats why the whole world still uses cast iron as a vehicle brake rotor material, there has never been anything to beat it and probably never will be. Pro cut machines work on both plain rotors and even better on slotted and drilled rotors of all types.

Who are Pro-Cut?

Pro cut are a USA based multi national and extremely professional corporation. Their machines are used and approved by many major car manufacturers and used all over the world to do exactly what they do best, correct for rotor mis-alignment no matter how it arises on a car. You cannot achieve this with any other device.

EBC Redstuff™ Ceramic Brake Pads

As EBC’s flagship street brake pad material for prestige and faster cars, EBC Redstuff™ ceramic Brake pads sets new standards in brake performance.

Product Information

High friction formula improves brake effect 15%. Redstuff™ ceramic brake pads have always been known for its low dust ability but the latest blend has greatly reduced the phenomenon of pad “Pick up” or disc scoring and reduced dust even further. Tested at the UK Motor Industries Research Association (MIRA) in witnessed tests early Redstuff™ reduced car stopping distance in tests by almost 50 feet from 100 MPH offering a staggering 30% brake improvement.

• Redstuff™ ceramic brake pads, passenger car/saloon car pad NOT made for Truck or SUV fitments
• EBC lowest dust fast street pad with 15% brake improvement
• Capable of repeated heavy brake use without brake “Fall-Off”
• Very minimal disc/rotor damage characteristics
• Superb material for Prestige imports/European and Asian cars
• ECE R 90 type approved for most cars
• Features red “brake in’ surface coating for instant safe braking after install

The Pad That Inspires Confidence

• Redstuff™ is only available for heavier and faster cars and does find its self at its best on slightly heavier cars. Selecting the right grade of EBC brake pad for you car is important and you can see the entire EBC selection and how to choose the right brakes for your car by switching to this linked page.

• Redstuff™ brake pads are however as a harder compound does take longer to fully bed in to achieve its highest levels of performance (can be up to 1000 miles/1600 Kms urban use) during which time the odd “Chirp” of brake noise may be heard when starting from cold in damp and cold conditions at walking pace speed. One press of the pedal to clear the rotor of any dampness and this disappears to leave EBC Redstuff™ a pad that inspires confidence in all cars. The motto is be patient give the pads a full chance to bed down.

• Brake dust has been rated by many OEM builders to be a more serious source of complaints than even brake squeal and as such EBC Brakes is proud to bring you with this new EBC Redstuff™ blend what is probably a world first in a pad that is almost dust free yet delivers performance braking.

• Less dust also means less rotor wear and it is almost guaranteed that your rotors will last double as long as when used with the more abrasive steel fibre brake compounds used by almost all of our competition.

• EBC Redstuff™ should be used at both front and rear for optimum balanced brake performance.

Performance

• High Performance lowest dust rating pads for Prestige imports and faster street driving.

• There are two reasons our customers love Redstuff, First because they are the lowest dust pad we have encountered by reducing dust by 60-90%. Plus the minimal dust you see is very easily removed with a simple sponge wash as it contains no steel fibre particles as in all other pads. Second they brake like an alligator right from cold (as good as Original pads or better) and just get better as they heat up.

• This material is a aramid fibre based brake compound enhanced with ceramic particles. If you have previously tried EBC Redstuff™ (pre-ceramic compound) this material is light years ahead. It lasts longer, it brakes better and is quieter.

Technical Info

Being a hard wearing pad, bed-in times can be as long as 1000 miles and drivers must be patient until the pad takes up the shape of their disc (brake rotor). This is a truly impressive fast road pad for repeated heavy braking. It emits far less dust than semi-metallic pads and has been proven to stop a passenger car/sedan/sport compact/hot hatch 13 metres quicker than OEM pads from 100mph/160kph. Features EBC Brake-In surface coating which conditions rotor surface and accelerates pad bed-in. Nominal friction coefficient 0.5 with approx. 50% dust reduction. Most EBC Red Ceramic pads are approved to ECE R90 brake safety regulation.
