Brake Master Cylinder Kits for Baron, Bonanza, Cleveland, and King Air models.
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.
For more information, go to Brake Assembly Master Cylinder Kits.
