Due to the rarity of all Brake Boosters we have implemented an “Exchange Only Policy Program”.  

  • You must send us your Brake Booster Core.  (Whether we rebuild your unit or have one in stock).
  • Please note, we do carry stock on a few makes and models. 
  • Please call us to find out if we have your unit in stock.  If we do, you must first send your old core to us prior to us shipping out the replacement.  Allow 2 to 3 days for processing your Unit.
  • Customer is responsible for all shipping charges.


  • We do not ship our Rebuilt Brake Boosters or Master Cylinders internationally.  
  • 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 your Classic.  


  • Front Master Cylinder Push Rod  75.00
