High Performance
73mm Brake
Caliper Kits
Take a look for yourself. The stock 58mm Caliper on the right and the 25% larger 73mm Caliper on the
left. This increased surface area of the brake calipers piston improves all around braking performance
by allowing more pressure to be applied to the brake pad and in turn agaiinst the rotor to improve
stopping distances while at the same time requiring less pedal effort. A great improvement inn
braking for all 1987-93 5.0L Mustangs. Cross drilled or slotted kits available. All kits include Hawk
High Performance Street Brake Pads, 73mm High Performance Front Brake Calipers.

Bedding Brake Pads Has a Couple
of Important Effects
The friction material in semi-metallic pads is held together by an
organic binder, usually a type of phenolic material. As the pads get hot,
the binder boils, and burns, from the top surface of the pad. Once this
burning or Bedding takes place the friction material makes proper
contact with the rotor.
Some race/performance pads, like the Hawk Performance
line of pads, are designated as pre-burnished from
the manufacturer. In our experience these pads still
benefit from bedding . Bedding pads establishes a
wear pattern between the pads and rotor. Some pads,
like the Performance Friction pads, deposit a layer of
carbon in the surface of the rotor. They need that
layer of carbon to perform at peak efficiency.
Racers should Bed a few sets of pads at a time. In
the event you need to change brake pads during a race,
you MUST use a set of bedded pads. Racing on nonbedded pads leads to a type of fade caused by the
binding agents coming out of the pad too quickly. This is called green
fade . These binders may create a liquid (actually a gas) layer between
your pads and rotors. Liquids have a very poor coefficient of friction.
This condition is the reason for reverse slotting or crossdrilling rotors,
as it allows a pathway for the gasses to escape.

Bleeding the Brakes
Bleeding brakes is not done with pressure, it is purely a function of
moving fluid through the system. The object is to displace air, not to see
how far fluid can be shot out of the caliper. Enlist who will help you bleed
the brakes. Make sure thay also read these instructions carefully (so they
understand the goal.)
Slowly pour fluid into the master cylinder so as not to aerate the fluid.
1
For systems which are essentially dry front and rear, start by
filling the master cylinder with proper fluid.
2
Next, at the caliper farthest from the master cylinder
attach the clear plastic bleed line to the bleeder and open it. VERY
SLOWLY stroke the brake pedal by hand or foot until fluid comes out.
Now close the bleeder.
3
ACTUAL BLEEDING SEQUENCE: a) Have your partner very slowly,
with modest pressure (approx. 25-30 ft/lb), stroke the pedal ONE
TIME until hydraulic resistance is encountered. Ask your partner to hold
at this point with the same modest and even pressure and notify you that
he is, holding. b) Open the bleeder, letting the pedal go to the floor or
until it stops using the same modest level of pressure, close the bleeder,
notify your partner, the system is sealed.
4
Repeat BLEEDING SEQUENCE (never stroke the pedal more than
one time), until all signs of air are purged (no bubbles) from fluid.
IMPORTANT NOTE: DO NOT LET THE MASTER CYLINDER RUN DRY, be
sure to check fluid level after every third bleeding sequence or sooner if
reservoir volume is very small.
5
Move to the location which is the next furthest from the master
cylinder and repeat the procedures previously outlined. Continue
until all calipers have been bleed. You are now 75% complete with the
bleeding process.
6
Take a small block of wood or a plastic hammer and carefully tap the
calipers to dislodge any additional air bubbles that may be trapped.
Spray all rotor surface with Brake Klean or a similar product to remove
all dirt and oils from your hand that may have been transferred to the
rotor during assembly. For street use, as with any time you open the
brake system, it may be advisable to repeat the bleeding procedure after
driving the vehicle for a day, as driving the car may dislodge some
additional air bubbles. For competition cars, we recommend repeating
this procedure directly after at least the first two sessions the car is on
the track and at the beginning of each race weekend thereafter.
Even if your pedal is high and firm, and additional bleeding is deemed
unnecessary, always inspect the calipers, hoses and fittings after the first
outing for signs of any fluid seeping and correct immediately.
