EBC Brake Pads
Being one that can not leave well enough alone, I decided to do some research
on brake pads. I ended up with several manufactures to study.
- Performance Friction
The Hawk pads come in several different grades of pads.
- HB111.610 Fronts
- HB183.585 Rears
HPS - High Performance Street
Hawk Performance HPS compound provides advanced braking characteristics to enhance your driving experience. This unique compound combines the safety and quality of Aerospace design partnered with the braking technology of motorsports.
- Extremely low dust
- High friction/torque hot or cold
- Gentle on rotors
- Virtually noise-free
- Much improved braking over OE
- Long extended pad life
HP PLUS - High Performance Street PLUS Race Worthy
Hawk Performance HP PLUS compound can take the heat at the Track and get you home safely without having to change your brake pads in and out. This compound was designed for the serious street and autocross enthusiast. Warning! Due to the dramatic friction levels produced by this product to achieve "race-level" braking; rotor wear, noise, dust, and pad wear may be increased.
- Extremely high friction output
- Race worthy for autocross
- Race worthy for club racing events
- Elevated temperature resistance
I was concerned that that the Street Plus might be harder on the rotors than the street ones so I emailed Hawk and asked. They said that yes there would be more dust and wear on the rotors compared to their Street pads. BUT that for their performance, their Street Plus pads were low dust and rotor friendly.
I emailed Carbotech and they apply all different kinds of pad materials to pads and shoes. They resell Hawk and performance friction.
I looked at the Performance Friction pads. I have had these pads on a Toyota for some time and they do a much better job at stopping than the factory pads did and are quiet after seating. I also had these same pads on my 95 Thunderbird and had no problem with them. They do seem to make a LOT of dust though, so they are probably not that friendly to the rotors either.
While searching for information on the Web I kept running across Miata sites that were praising the EBC street pads. EBC got their start by perfecting motorcycle brakes. In the late 80s they launched their automotive range of Kevlar Disc Brake Pads.
They make pads in three different grades. Note:Their website says they offer three grades but documentation with the pads claims a 4th grade also.
EBC Greenstuff Roadsport Compound
Suitable for all fast road applications
This pad features a high Kevlar content formulation resulting in an ultra high performance road pad which is extremely kind to discs. With a friction co-efficient of around 0.46µ and high resistance to brake fade (550º C) this pad is a superb upgrade for high performance street cars, high speed freeway use and consecutive heavy braking.
EBC Redstuff Semi-metallic Compound
IDEAL TRACK DAY PADS!! Suitable for light to medium race applications, fast road usage by heavier cars and track day use. EBC's semi-metallic Redstuff formulation is a true asphalt race pad with medium lifetime and a friction level of about 0.3µ steadily rising to 0.33µ at 750ºC. Redstuff is very kind to brake discs and can be used on highway vehicles for extreme duty use as well as on race cars.
EBC Yellowstuff EBC's flagship race compound
Yellowstuff is EBC's longest lasting full race compound, again exhibiting zero brake disc damage.
Yellowstuff has an average friction level of 0.34µ delivering awesome stopping power right up to 900ºC
I thought it was interesting that the EBC people actually told you where the pads came in at on the friction scale. I could not find any of the other manufactures specs on this.
The most important thing to remember when choosing a high performance pad is to match the pad to the use it will receive. If the pads temperature range is exceeded then you will not have the braking you need.
If the pads temperature range is not Reached then you will not have the braking you need.
Also the higher temperature the pad will take then the harder they are going to be on the rotors.
Seeing as how the closest my car will ever get to the race track will be watching NASCAR on TV, I was only interested in a better performing street pad.
I went with the EBC because of their higher temperature for the street pads and the fact that they claim higher friction and excellent COLD braking abilities. Also the near dustless or dustfree as some of their literature claims would not be a bad thing either.
NOTE: I ordered the EBC Front and rear Greenstuff. HOWEVER when I went to put the rears on.... THEY WERE TOO THICK.
The GT pads are 17mm wide and the Cobra/Bullitt are 15mm wide. My vendor offered to refund the pads or he said I could just sand them down. I used 80 Grit sandpaper on a 3" belt sander to reduce each pad by 2mm. Took about 2 hours total. I had the sander fixed upside down and I simply laid the pad on the sander untill it was too hot to hold and then moved to the next pad while the others were cooling back down.
Also there is a special tool you need for ratcheting the rear pistons back in once the pads start to wear. I would imagine that it has something to do with the design of the parking brake.
New EBC Pads
- Fronts DP21131
- Rear DP21156
The rear pads are for the GT and are 2mm too thick. If you are going to use them then you will need to sand them down.
