Due to the rarity of all Brake Boosters, we have implemented a “Rebuild and Return Only Policy Program”.

  • You must send us your Brake Booster Core.
  • Customer is responsible for all shipping charges.


  • We do not ship our Rebuilt Brake Boosters or Master Cylinders internationally.
  • If a Brake Booster is first shipped to a U.S. address and then forwarded to us, we are not responsible for the Unit and our warranty is null and void if it is shipped out of the country internationally. We are not responsible for any shipping or other costs that may be incurred.
  • The weight of each brake booster and/or master cylinder make it cost prohibitive to ship out of the country should your Unit be damaged in the process, or you experience any issue that would require attention.
  • We can however provide you with our full line of Brake Booster Major Repair Kits and Master Cylinder Repair Kits for power brake equipped cars only.
