  • Manufacturers all major components in house.

  • Castings go through 2 inspection processes (via micrometer and via go-no go fixture check) before being sent to the assembly department insuring all machining is correct and matches the OE
  • Before assembly all castings and components are cleaned by automated ultrasonic cleaning machines
  • Assembly is done in clean room insuring no contamination is introduced into final assembly

  • Q:

    HELP I recently bought this and it is an exact fit.....but when i see in videos the bench bleeding process...i dont see a video that has one like this...just ones where the pump is sticking out. so what if you have no vice to bleed? do you jack up the car before or after installing it? and i bought my drum brakes and shoes as well...I hear you can replace them after installing the cylinder..since you need to bleed the brakes anyways with both projects.Anyone know a protocol/steps to doing both in one day? drum/shoes first or cylinder first?

      I'm still learning but my rule of thumb is if your engine has trac control it is best to buy a part that can be used for its purpose. I know it cost a bit more....but if it gives you peace of mind...go for it. I knew i needed it with trac because after i did a brake diagnostic check at a shop i saw they were looking to put that in at a high price....just went ahead and bought it and going to put it in myself. But im not a mechanic someone might say you dont need it. i just go with replacing what was already there. Good luck.
