StopTech Big Brake Kits deliver championship-winning performance with original equipment quality, dependability and user friendliness. Each Big Brake Kit is engineered to provide optimum stopping performance for each vehicle application.
StopTech Engineering and Testing
StopTech's southern California facility houses our engineering and manufacturing departments.   
Over 75,000 square feet of production space are dedicated to StopTech brake systems and Power Slot performance replacement rotors.
StopTech Big Brake Kits are engineered to optimize braking performance for each vehicle application. Component and kit designs are produced in Solidworks, and FEA studies are completed in Solidworks Simulation.
StopTech's engineering team utilizes advanced data acquisition tools to measure and inspect components.
Computer controlled CMM machines inspect components for dimensional accuracy.
Advanced optical inspection processes ensure each component meets stringent quality control requirements.
StopTech has invested in two Link Engineering brake dynos to perform in-house testing of our brake components and systems.
Big brake kit calipers, pads and rotors are dyno tested to determine their performance characteristics under different operating conditions. Test parameters may include repeated stops from 160mph, or extended driving cycles to measure wear life.
Our first Link 3900 brake dyno was placed into service in January 2008. Since then it has been used primarily to test passenger and light truck applications. As delivered from the factory its air handling system provided 150mph of airflow. Modifications made by StopTech increased the air velocity limit to 210mph. Dyno #1 can simulate GVW's (gross vehicle weights) of up to 12,000 pounds.
Our second Link 3900 dyno entered service in February 2010 and has been used primarily for full-size truck testing including drum brakes, armored vehicles, and for parking brake testing. Dyno #2 has also been configured to reach a maximum air velocity of 210mph and can simulate GVW's of up to 24,000 pounds.
Sensors monitor brake rotor temperatures throughout the testing process.
Temperature sensors embedded in the inner and outer brake pad provide real-time temperature data during the testing process.
In addition to our in-house testing capabilities, StopTech performs extensive on vehicle testing.

On-vehicle FMVSS testing is performed using the Link 3801 Data Acquisition System.  For quick setup and changeovers, especially during racetrack testing, we also employ the VBOX 20SL3 GPS Datalogger featuring simultaneous 3-axis measuring.

StopTech Caliper Production
Each StopTech brake caliper starts its life as a forged aluminum blank. Each brake caliper is then finished utilizing the latest production processes and machines.
Using specially engineered production jigs piston bores and mating surfaces are CNC machined.
After all bores and mating surfaces are finished. StopTech calipers are finish machined. For the Trophy caliper the weight is reduced  up to 20% and the engraved logo added.
All inlets and fluid ports are finished machined and threads cut.
These Trophy calipers have completed their machining process and are ready for final finishing and anodizing
After final inspection and approval, caliper bodies are hard anodized. This finish is specially designed to handle extreme temperatures associated with hard braking situations.
Finished caliper bodies have pistons, pressure seals, dust boots and abutment plates installed
Once all the components are installed, the two caliper halves are mated together and sent for final inspection and pressure testing.
Each StopTech caliper is pressure tested to over 2700psi. This step ensures proper operation of the caliper under the most demanding conditions.
After passing QC and pressure testing. Each StopTech caliper is boxed and labeled for shipping.
STOPTECH AeroHats
StopTech's patented AeroHats are manufactured from Alcoa aluminum alloy bar stock, pre-aged for optimal tensile strength and corrosion resistance.
AeroRotor hats are CNC machined for each vehicle application.
Aircraft grade hardware is used to mate AeroHats and Rotors. The specially engineered drive pins have been developed to handle the stresses of heat cycling and repeat stops.
Split cast AeroRotor rings and hats are assembled and sent for final inspection.
Each AeroRotor recieves a visual inspection and is checked for run-out. This process ensures proper alignment of the rotor components and eliminates vibration and feedback after vehicle installation.
StopTech Caliper Brackets
Application specific caliper brackets are machined from premium billet aluminum.
After machining each bracket is inspected before being sent for anodizing.

StopTech Stainless Steel Brake Lines
StopTech stainless steel brake lines consist of a Teflon® inner hose supported by a layer of woven stainless steel braid that is wrapped in a clear PVC plastic coating. Each application specific hose is engineered and manufactured to provide optimum performance.
Finished Big Brake Kits
Following final QC inspection, each StopTech Big Brake Kit is boxed and ready for shipping.
Stoptech's attention to detail, advanced engineering and manufacturing techniques result in superior quality and performance make Stoptech Big Brake the only choice for championship winning production based race teams.
