Brake Master Cylinder Kits for Baron, Bonanza, Cleveland, and King Air models.

  • Improved lip seal eliminates main O-rings
  • Better sealing performance at any temperature
  • Rebuild your brake master cylinder - no need to purchase a new replacement!
  • Easy to install - tooling included
  • STC Approved - STC# SA04634NY

All kits include all O-rings and hardware to refurbish and upgrade your brake master cylinder, plus their proprietary Piston Rod Lip Seal. Their Piston Rod Lip Seal design combined with the advanced self-lubricating elastomeric polymer offers superior performance and durability over the traditional rubber O-ring.

Note: The piston is not included in this kit. This kit DOES NOT fit brake master cylinders manufactured by Gerdes or Paramount. 

Caution: Thorseal® is made from Marsh Brothers’ proprietary material known as AeroLas™-Flex which is not compatible with phosphate ester hydraulic fluid, commercially known as Skydrol. Exposure to this fluid contamination will damage the seals.
