Most 17” wheels will clear the outer diameter of the caliper of the 332mm kit and most 18” wheels
will clear the 355mm kit. However, the more critical clearance is the gap between the spokes of the
wheel and the face of the caliper. Do not assume a 19, 20 or even 24 inch wheel will clear the face of
the caliper.

Wheel Spacers
Wheel spacers can provide extra clearance to the outer face of the caliper. This will also space out the
entire wheel, widening the track width of the vehicle. Fender clearances should be checked on
lowered cars, and longer lug studs or wheel bolts are usually required. Note: The Wheel Industry
Council has issued guidelines advising wheel spacers not be used.

Brake Vibration - THIS IS IMPORTANT!
The most common cause of brake vibration is improper bedding of pads and rotors or improper
pad selection for the specific driving environment. Rotor runout may also cause vibration, but
precision manufacturing and inspection typically means runout is not an issue. Double disc grind-
ing insures the rotor runout is within +/- 0.002” when installed on our aluminum hat and controls
thickness variation within 0.0003”. Under the most extreme conditions, any rotor may warp, but
uneven pad deposition is a more typical vibration cause. If the system is not properly bedded in, or
street pads are run on an open track, uneven pad deposits will occur causing an ever worsening
vibration. Failure to immediately address a pad deposition/vibration issue may lead to permanent
damage of the rotors. Please read and understand the bed-in procedures included with this manual.
If you have any questions, please contact the StopTech Customer Service Department for assistance.

Brake Noise
Certain brake pad compounds make more noise than others. Proper anti-squeal shim plates be-
tween the caliper pistons and backing plate of the pad help reduce the problem. Anti-squeal lubri-
cants are also available to reduce some of the noise. The reality is, performance pads are more prone
to brake squeal.

The AeroRotors supplied with this kit are coated with a water soluable, environmen-
tally friendly rust inhibitor. This coating MUST BE WASHED OFF WITH SOAP
AND WATER before installation. Brake cleaner is not as effective as soap and water.
Even if it doesnt look as if anything is coming off the rotor, the rust inhibitor is there
and must be entirely cleaned. Rotors will quickly rust without protection. If the
rotor is not rusty, it’s still coated. After cleaning, you will see the rotor immediately
start to develop a slight rust color. This is normal and desirable as it indicates all the
rust inhibitor has been removed.
Proper rotor and pad break-in is essential to the performance of your new brake
system. Failure to properly break-in the brakes will seriously impact how well they
work and how long they last. The number one cause of brake vibration is uneven pad
material deposition on the rotor. Proper break-in will greatly minimize such prob-
lems.
Follow the break-in procedures listed later in this manual as closely as possible.

Do not assume your wheels will fit. An outline drawing of your StopTech Big
Brake kit is available on our website at http://www.stoptech.com. Measure the
distance from the outer face of your stock caliper to the inner face of your wheel
spokes, or make a template according to the instructions on the website and deter-
mine if a wheel spacer may be necessary. DO THIS BEFORE YOU INSTALL
YOUR KIT!
If you have any questions about wheel fitment, rotor cleaning or
break-in of a particular pad type, please call our Customer Service
Department @ 310-325-4799 X 105 or you can e-mail directly to

Retain the clip. It will be used with
the new brake line.
Be careful of any fluid which may drip
from the end of the line.
Using a 12mm wrench or socket, remove
the bolt holding the line positioning
bracket to the vehicle.
Remove the caliper with stock brake line
attached. There may be some leakage from
the open end of the brake line, especially if
the pads/pistons on the caliper are retracted.
Note: It is helpful to turn the steering away from the side you are working on so the
wrench handle clears the rear of the wheel well.

Caliper bolts may be very tight from the factory.
Ensure that you have a good purchase on the head
of the bolt and are in a good position to turn the

Remove the stock rotor. It may be necessary
to strike the outer edge with a non-marring
hammer if corrosion prevents the rotor from
simply pulling off. If so, place a wheel nut on
one of the studs first to prevent the rotor from
falling when it comes loose.
Remove the two stock caliper bolts with a 17mm

Use a 10mm wrench or sockett to remove the

Use a cut-off wheel to cut the edge of the shield
in the area shown. Cut as far as possible without
cutting into the spindle or upright.
Use a plier to twist un-cut portion of
the shield until it tears through.
Rotate the shield and make a second cut far enough
from the first that when the cut section is removed
the shield can be worked off the upright.

- Determine the left and right side calipers. The calipers are marked on each box. As a
check, the bleed screws always go to the top of the caliper.
Remove the 2 bolts holding the caliper bridge using a 5mm Allen wrench.
Remove the caliper bridge taking note of the direction it is installed in and the correct location of
the pad retaining wire clip, which typically, but not always, stays attached to the bridge.
In order to stiffen the caliper, the
bridge is a snug fit and the bolts
may be tight when removing. Keep
turning bolts gently with pressure
applied in the direction of removal.
After removing the bolts, it may be
necessary to tap the bridge out from
the inside of the caliper with a plas-
tic or leather hammer or similar
tool. The handle of a tool works well
for this. With use, the bridge and
bolt will become easier to remove
and install.

If the fit of the bridge into the caliper is tight it may be necessary to tap into position with
a mallet. While applying pressure to the bolt head, adjust the position of the bridge until
the bolt slides more freely into place.
Apply a light film of anti-sieze compound onto the bridge bolt shaft and threads. Insert the
first bridge bolt and start the first few threads using a 5mm Allen wrench. Gently press the
opposite side of the bridge with the palm of your hand, or tap with a mallet until the second
bolt engages the hole. With pressure still applied, start the second bolt. Torque each bolt to

Remove the rubber cap from the hard line and screw
the fitting into the new brake line by hand for a few
turns before tightening with a 10mm flare wrench.
Be sure the flats on the line fitting line up in the chas-
sis bracket to assure proper fit and retention.
Re-install the stock retaining clip, tapping it into
place with a small hammer.
Install the banjo bolt into the caliper with a
copper crush washer on each side of the
Banjo fitting. Route the line approximately
the same as the stock brake line.
The Banjo bolt only needs to be tightened enough to seal
the crush washers. Excessive torque can damage the
threads inside the caliper and/or damage the Banjo bolt.
Install the line locator tab in the same
spot as the stock line using the new bolt
supplied with the kit.

Bleed the brake system using an 11mm wrench on the bleed screws:
- The sequence for bleeding the brakes should be:
1. Right outboard bleed screw
2. Right inboard bleed screw
3. Left outboard bleed screw
4. Left inboard bleed screw
After initially bleeding the system, gently tap the caliper body with a non-marring mallet or
hammer to dislodge any small air bubbles and re-bleed.
Note: The calipers and lines will need to fill with fluid, quickly draining the master cylinder reser-
voir. Keep a close watch on the fluid level when initially bleeding the system. Do not allow the
master cylinder reservoir to run dry and draw in air. Doing so may require the brake system to be
serviced by a certified brake technician.
After bleeding, apply a constant pressure to the brake pedal and check all connections,After bleeding, apply a constant pressure to the brake pedal and check all connections,

Because of the unusual angle of the caliper on some ve-
hicles, it may be necessary to use the following special
technique to bleed the brakes for the first time:
Remove both caliper bracket bolts leaving the caliper at-
tached to the bracket
Tilt the caliper to the vertical position shown and sup-
port the caliper so the pads are still over the rotor
Bleed the brakes
Reinstall caliper bracket bolts
Tighten both caliper bracket bolts to the specified torque
This special bleeding tecnique will not be required again
unless air becomes trapped in the calipers.
