Replacement AeroRotors (Made in USA!)
Each StopTech AeroRotor includes a
hat installation kit with
replacement drive pins, screws, anti-rattle washers, Loctite 290 thread
locking compound, and an instruction sheet. More comprehensive
instructions with photos may be found here:
Instructions for replacing StopTech rotors
Listed
prices are per rotor. Left and right rotors required.
StopTech AeroRotors are 100% made in the
USA, with casting and machining done in California. The manufacturing
facility is equipped with state-of-the-art Doosan vertical turning centers,
Doosan 3-axis CNC mill and Balance Technologies rotor balancing machine.
Many customers who track their cars purchase a second set of rotors and hats as spares. If a
rotor becomes too worn or cracks, it can easily be swapped at the track with
a new rotor/hat assembly. After the event, the old assembly
may be freshened with new rotors, drive pins, bushings, and washers at a time
and place of your convenience. Taking apart and reassembling brake
components still hot from the track, between run sessions, often in grueling
heat or pouring rain does not contribute to the enjoyment of motorsports!
Save yourself the hassle and order a spare set of hats or a complete
hat/rotor assembly. Contact
Zeckhausen Racing for pricing.

Replacement AeroHats
Many customers who track their cars regularly,
purchase a second set of rotors and hats as spares. If a rotor becomes
too worn, it can be swapped at the track with a complete new rotor/hat
assembly. After the event, the old assembly may taken apart, inspected, and freshened up with new rotors, drive pins,
bolts, and washers at a time and place of your convenience.
Taking apart and reassembling brake components still hot from the track,
often in grueling heat or pouring rain, does not contribute to the enjoyment
of motorsports! Save yourself the hassle and order a spare set of hats
and rotors.
Hats should be considered wear items, just like rotors
and pads. For street driven cars, old hats may be reused several times
with new rotors, although winter driving on salty roads may accelerate
corrosion. For track cars, depending on the severity of duty,
the hats may need to be replaced much sooner. Each time the rotors and
drive hardware are replaced, the installer should closely inspect the hats
for any sign of damage or cracking, especially around the rotor mounting
holes. If it doesn't look right, be safe and replace the hats!
Hats are specific to each big brake kit application.
Since StopTech's hats are directional for improved airflow, there is a left
and a right part number. Contact Zeckhausen Racing for the correct
part numbers for your car's big brake kit. Prices shown are
approximate, since some applications require more complicated (and thus more
expensive) hat designs.

Titanium Backing
Plates
Racers with competition tires and/or heavy, powerful cars, may experience fluid fade and destruction of
caliper dust boots, even after
the installation of a big brake kit. In order to control the transfer
of heat, some race pads use special materials which act as insulators
between the pad friction material and the backing plate.
These titanium backing plates, placed between the pad and
the caliper, dramatically reduce heat transfer, preventing dust boots from vaporizing and reducing the
temperature of the brake fluid. They are especially effective when the
pads have worn by 50 percent or more, since worn pads do not provide as much
thermal insulation between the rotors and the calipers.
To order titanium backing plates on-line, click here:
and then select the correct
part for your caliper. Or, feel free to call us at (800)222-8893.

Caliper Rebuild Parts
For street applications, most calipers will
never have to be rebuilt for the life of the vehicle. However, with track use, dust boots and pressure seals may eventually become
brittle and crack. This can result in brake fluid weeping past the
pressure seals or even loss of brake pressure. For this reason, it is
suggested that club racers rebuild their calipers at the end of each racing
season. Some professional race teams replace caliper seals after every
race. For most customers, only pressure seals and dust boots will be
required. However, under very severe racing conditions, especially if
race pads have been worn all the way to the steel backing plates, there may
be distortion or cracking of the pistons. If any cracks or distortion
are observed, you should replace the pistons. Calipers on race cars
should be inspected regularly and components replaced as necessary.
Warning: StopTech caliper
piston sizing is unique to each application. Pressure seals and
dust boots are not returnable if the wrong sizes are ordered. Please measure
caliper piston diameter before ordering.
Click here for instructions on
piston measurement. |

|
Dust Boot & Pressure Seal Kit
Each kit includes two dust boots and two
pressure seals. Order one kit per 2-piston
caliper, two kits per 4-piston caliper, 3 kits per 6-piston caliper, and 4
kits per 8-piston caliper.
Example: For a StopTech ST-40 4-piston caliper
with 36 and 40mm pistons, you should order one each of part numbers
143.99036 and 143.99040 to rebuild one caliper.
Save $5 per rebuild kit, over the cost of
purchasing individual parts. Save $40 total when rebuilding four
4-piston calipers! |

GiroDisc Caliper Pad & Piston Spreading Tool
Save time and protect your caliper from cocked
pistons when changing pads with this unique tool. A must for anyone
who changes pads with regularity. Works with most 2, 4, 6, and
8-piston calipers. I have one of these amazing tools in my own shop
and was recently timed at less than one minute to change the pads on
a Porsche 993 TT caliper. (The wheel was already removed.) This
is our new favorite tool. |
