| POWER STOP/AUTOSPECIALTY FRICTION PRODUCTS
Autospecialty supplies premium grades of brake pads featuring
non-asbestos Abex and Axxis friction materials in our 911 Extreme
Performance, Metal Master and Metal-lux pads and shoes for the
discerning driver. |
| 911 EXTREME PERFORMANCE 26- Series (by Abex
A non- asbestos disc brake pad from AUTOSPECIALTY) 911
Extreme Performance is a proven performer for police cars, taxis,
ambulances, buses, medium duty trucks and other critical use vehicles.
This compound is the O.E.M. friction used on 1995 and newer
Ford Crown Victorias with the police package and is FMVSS 105
approved. |
| AXXIS Metal Master 23- Series (byAbex) A premium
asbestos free semi-metallic brake pad, Metal-lux is an excellent
replacement pad for the driver wanting an O.E. quality asbestos
free semi-metallic pad, or wishing to upgrade from present organic
brake pads. METAL-LUX is the "WORK HORSE" pad for the today's
vehicles. |
| 911 EXTREME PERFORMANCE Brake Shoes 32- Series - (High
Performance non-asbestos riveted brake shoe) Specifically formulated
for severe and high performance vehicle applications, these
shoes are engineered to provide superior stopping performance
while maximizing fade resistance and wear life during operation
under high temperatures & heavy loads. |
| ABEX Friction Products Abex is an O.E.M. friction
manufacturer and has been awarded the coveted Q-1 Award from
the Ford Motor Company. Abex friction is the most consistent
product in the market. After a formula has been approved the
following tests occur on an ongoing basis to make sure that
Abex products stays consistent. |
| Thermal Gravametric Analysis (TGA) This consists of
heating an oven at a controlled rate, placing a piece of friction
material into the oven and letting all of the fillers and impurities
burn off. The weight is then measured and compared to the weight
of the sample prior to the burn off. The weight loss can then
be related back to brake fade, because the material burned off
is not a necessary component of the friction. |
| Thermal Mechanical Analysis (TMA) A piece of friction
material is heated and then measured, then allowed to
cool and again is measured. Swell from the original dimension
is then determined. If the swell is too great, it could cause
the brake pad to remain in continuous contact with the rotor,
causing the brakes to over heat. This condition would lead to
premature brake wear or brake fade. |
| Swell Growth and Dimensional Stability test (SGDS/SAE)
A piece of friction material is rapidly heated to 400° F in
an oven for one hour, after which the dimensions are compared
to the originals. Here again, too much swell can cause premature
wear, though initially it may appear that the pads are lasting
longer until the fillers and impurities burn off. After this
has occurred the pad will experience rapid wear and unpredictable
braking characteristics. |
| Friction Assessment Screening
Test (F.A.S.T.) In this test, a set of pads are installed in
the test machine. This machine will then run at approximately
25 mph for 90 minutes while a hydraulic system maintains
constant pressure on the pads against a rotor. This test evaluates
not only friction material swell and dimensional stability,
but also allows engineers to forecast the life expectancy of
a set of pads. |
| SAE J843d Performance Test This is
the most important test, as it is on the actual vehicle.
This test consists of two stages: |
| Stage 1: The first stage consists of 200 stops from 60
mph to 0, using a "fresh" or "pre-burnished" set of pads. The
SAE specifications require that the stopping distance be no
more than 216 feet, while pedal pressure is not to exceed 150lbs.
|
| Stage 2: The second stage consists of another
200 stops from 60 mph to 0, using a set of "broken-in" or "
post-burnished" set of pads. The SAE specifications require
that the stopping distance be no more than 206 feet, while pedal
pressure is not to exceed 150lbs. All Abex pads meet or
exceed these performance specifications. In fact, Abex performs the
J843d test with a more realistic 60 pounds of pedal pressure.
Not all major manufacturers meet these specifications and many
do no testing at all. |
