Caliper Clearance
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.
It is the responsibility of the customer to insure wheel spacers are properlyIt is the responsibility of the customer to insure wheel spacers are properly

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 grinding 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 between the caliper pistons and backing plate of the pad help reduce the problem. Anti-squeal lubricants are also available to reduce some of the noise. The reality is, performance pads are more prone
to brake squeal.

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 determine if a wheel spacer may be necessary. DO THIS BEFORE YOU INSTALL
YOUR KIT!
Cleaning of Rotors:Cleaning of Rotors:
Cleaning of Rotors:
Cleaning of Rotors:Cleaning of Rotors:
The AeroRotors supplied with this kit are coated with a water soluable, environmentally 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 doesn’t 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 problems.
Follow the break-in procedures listed later in this manual as closely as possible.
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

Note: If you remove the bottom lug nut last while holding the bottom of the tire, it will lessen the
chances of the wheel tilting on it’s own and make removal easier.

Use a screwdriver or pliers to remove the
metal spring clip holding the stock brake
line to the chassis bracket.
Retain the clip. It will be used with
the new brake line.
Finish unfastening the solid brake line and pull it clear of the bracket.
Quickly snap one of the supplied black
rubber caps over the end of the hard
line. This should control brake fluid loss
for the duration of the installation.
Using a 12mm wrench or socket, remove
the bolt holding the line positioning
bracket to the vehicle.
Be careful of any fluid which may drip
from the end of the line.
