Replacement 2-Piece 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

Folks who track regularly, often purchase a second set of rotors and hats as spares.  If a rotor becomes too worn to continue, it can be easily swapped at the track as a complete rotor/hat assembly.  After the event, the old assembly may taken apart and freshened up with new rotors and mounting hardware at a time and place of your convenience.  Taking apart and reassembling brake components 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 are 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 sooner.  Each time rotors and drive hardware are replaced, the installer should inspect the hats for 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.  StopTech hats are directional, for improved airflow, so there is a left and a right part number.  Contact Zeckhausen Racing for the correct hats for your car's big brake kit.

Titanium Backing Plates

Racers with competition tires or heavy, powerful cars, may experience fluid fade and destruction of caliper dust boots, even after the installation of a big brake kit.  Titanium backing plates can help.

Titanium plates approximately 0.8mm thick, placed behind each brake pad, significantly reduce heat transfer, preventing dust boots from vaporizing and reducing brake fluid temperature.  They are especially effective when the pads have worn 50 percent or more, since worn pads do not provide much thermal insulation between the rotors and the calipers.

To order titanium backing plates, click here: and select the correct part for your caliper.  Or call us at (800)222-8893.

Caliper Rebuild Parts

For street applications, most calipers 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 pressure seals or even loss of brake pressure.  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 severe racing conditions, especially if race pads have been worn to the backing plates, there may be distortion or cracking of pistons.  If so, you should replace the pistons.  Calipers on race cars should be inspected regularly and components replaced as necessary.

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. 

Instructions: How to measure pistons

Dust Boot & Pressure Seal Kit

Each kit includes 2 dust boots and pressure seals.

Example: StopTech 4-piston caliper with 36 and 40mm pistons, order one each of part numbers 143.99036K and 143.99040K to rebuild one caliper.

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.
