Bleeding
the brakes requires a properly sized box wrench for the bleeder
and the clear plastic bleed hose provided with your system.
Good quality, non-silicone fluid is also a must. Baer Brakes
has tested a wide variety of fluids and strongly recommends
Performance Friction’s Z-Rated fluid #90016 for street
and occasional track use (with Motorcraft PM1 our backup suggestion
for this same duty). These two have been proven to be more effective
than fluids that are often many times more expensive. For racing,
Baer recommends and uses only Castrol SRF. Baer stocks and sells
both the Performance Friction Z-Rated and Castrol SRF.
Always
remember, good to excellent brakes or fluid do not function
without adequate cooling. In fact, the more serious your brake
system, the more attention that needs to be directed to proper
ducting, as they will generate more heat due to increased
capacity.
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!
Proper
Bleeding Technique
Enlist
someone who will help you bleed the brakes. Make sure they
also read these instructions carefully (so they understand
the goal).
For systems
which are essentially dry front and rear, start by filling
the master cylinder with proper fluid. Pour slowly so as not
to aerate the fluid.
Next,
move to the first caliper, attach the clear plastic bleed
hose to the bleeder and open it. Hold the hose upright so
that you can monitor the escape of air bubbles. VERY SLOWLY
stroke the brake pedal by hand or foot until fluid comes out.
Now close the bleeder.
ACTUAL
BLEEDING SEQUENCE:
Have
your partner very slowly, with modest pressure (approximately
25-30 lbs.ft.), 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.”
Open
the bleeder, letting the pedal go to the floor or until it
stops, using the same modest level of pressure, then close
the bleeder again. Notify your partner “the system is
sealed.” He can then slowly release pedal pressure.
Repeat
the 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 the fluid level after every third bleeding sequence
or sooner if reservoir volume is very small.
Before moving to the next caliper, take a small block of wood
or a plastic hammer and carefully tap the caliper to dislodge
any additional air bubbles that may be trapped. Then bleed
one last time.
Move
to the next caliper and repeat the procedures previously outlined.
Continue until all calipers have been bled. Before re-installing
wheels and placing the car on the ground, we recommend you
carefully wipe clean all caliper surfaces, hose joints and
fittings, making sure they are all dry and free from seepage.
If not, inspect and tighten appropriately. Spray all rotor
surfaces with Brake Kleen® or a similar product to remove
all dirt and oils from your hands that may have been transferred
to the rotor during assembly. Also remember to remove the
nut that has been holding rotor in place before attempting
to re-install the wheel.
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 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 seepage
and correct immediately.
