Replacement inner member for UFP A-60 and A-70 surge brake actuators designed for tandem axle trailers with hydraulic disc brakes. Provides complete internal braking function including master cylinder and reverse lockout.
R&P Knowledge Hub
Compatibility: Fits UFP A-60 and A-70 surge brake actuators configured for hydraulic disc brakes.
Vehicle / System Fit: Designed for tandem axle trailers with four-wheel braking systems.
Installation Notes: Inner member swaps require proper bleeding of hydraulic system and inspection of brake lines.
Performance Insight: The inner member contains the master cylinder and sliding mechanism—core components responsible for converting trailer momentum into braking force.
R&P Service Insight
Inner members are commonly replaced due to hydraulic wear or corrosion inside the actuator housing.
- Hydraulic Fatigue: Internal seals degrade over time
- Corrosion: Moisture exposure impacts internal components
- Loss of Braking Pressure: Reduced performance under load indicates internal failure
