Product Description:

RCK70101 – Sheet Metal Cap Seal is a fundamental sealing element in heavy-duty disc brake calipers, sealing the connection line between the mechanism cover and the main body. This part creates a closed working space by preventing contact between the adjustment gears, spring groups, and bearing surfaces inside the caliper and the external environment. It supports the precise fitting of the sheet metal cover to the body and provides a controlled environment within the system.

Maintaining the elasticity of this seal is crucial during caliper overhaul and maintenance. A seal that hardens, compresses, or loses its shape over time can allow moisture and dirt particles to reach the mechanism area. This can reduce the performance of the internal lubricant, leading to irregular operation of the adjustment system and negatively affecting brake characteristics. Therefore, RCK70101 is one of the critical sealing components that must be checked during every comprehensive maintenance.
