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!).

Balanced is Better™

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 Truck Yellowstuff™ Sport Brake Pads

Because of its huge heat range, the applications where EBC Yellowstuff will deliver benefits range from fastest street use on higher horsepower cars and race use on most street based cars and even as a brake upgrade on Trucks and SUV.

High Efficiency Performance

• Truck Yellowstuff Sport brake pads are especially appreciated on Trucks for towing and heavy loads and where wheel and tire oversize upgrades have been fitted.
• Truck Yellowstuff Sport brake pads are not rated as low dust but create lower dust to OEM pads. These pads are a full FMVSS grade higher in friction level than most stock pads and as such will feel stronger on the pedal after install and bedding.
• The pads are also a race developed friction material designed for heavy heat and brake abuse. As an ideal upgrade pad when fitting oversize tyres and wheels, the EBC yellowstuff brake pads have been tested to destruction by the likes of Randy Merritt of Mongo Racing in off road desert racing.

Features

• Truck Yellowstuff Sport brake pads are a high friction formula that improves brake effect 30%
• Zero brake fade makes this material perfect for heavier loads such as towing
• Capable of repeated heavy brake use without brake “Fall-Off”
• Very minimal disc/rotor damage characteristics
• Suitable for all light trucks, Jeep and SUV in highway use
• Superb brake control and pedal response
• Features red “brake in’ surface coating for instant safe braking after install

Performance

Ultra high friction brake pads for US built trucks and 4×4 vehicles.

• If you want improved stopping power with just a pad change, this is the perfect pad choice. This refined version of the famous EBC Yellowstuff race formulation is now available in pad designs to fit popular American trucks/pick-ups and many Asian and European built 4x4s. This fast growing market for improved horsepower trucks and oversize wheel conversions has thrown up a black hole requiring a performance pad to fit these makes and models that will stop even the fastest driver in a heartbeat. Average friction coefficient 0.5 with similar dust to original pads and the dust is the same or perhaps slightly more than many original pads, this is not a low dust pad.
• Stretched limos is another superb application for this material. EBC Brakes is now supplying this compound for stretched F250s, stretched Excursions, stretched Hummers which are subject to a PSV (public service vehicle) test. Vehicles which failed the PSV test with standard brakes passed the test quoting a 20% brake improvement when using this material.
• Yellowstuff performance range is a high friction aramid fiber pad, totally resistant to brake rotor vibration, and easy on rotors.
• Many part numbers now carry ECE R90 approval.

Trucks

USA Light Truck Drivers love it because…

Normally race pads require warm up….but not the EBC Yellowstuff. This compound works well from cold and is therefore a perfect solution if you simply want the best stopping power you can get for street use on a truck or SUV where the brakes are “Marginal” from the factory or you have enhanced your ride with oversize wheels tyres or raised suspension, all of which place much higher demands on the brakes.

Drivers with Trailers love it because…

Towing brings extra loads and that mushy feel of many stock or low friction aftermarket pads does not inspire confidence. EBC Yellowstuff gives you as much bite as you can get from a stock system and in most cases will give a noticeable brake improvement under loads of towing.
