A-60 Hydraulic Drum Brake Actuator UFP Inner Member Slide Assembly for One Axle - 75K
Complete A-60 inner member slide assembly for compatible hydraulic drum brake actuator housings. This listing is for one inner slide assembly for one compatible 7,500 lb GVWR hydraulic drum brake actuator application; outer housing and wheel-end brake parts are not included.
Overview
This A-60 hydraulic drum brake actuator inner member slide is a complete replacement inner assembly designed to install into an existing compatible A-60 outer actuator housing. It includes the internal working components needed to help restore proper surge brake operation on compatible hydraulic drum brake trailer systems. This is a one-actuator service assembly for a 7,500 lb GVWR application, not a complete axle brake kit.
R&P Service Insight
Replacing the inner slide can be a practical repair when the outer housing is still serviceable and the hydraulic drum brake actuator needs renewed internal function.
- System Match: Use only with compatible A-60 hydraulic drum brake systems.
- Housing Required: This listing is for the inner member slide, not the outer actuator housing.
- Pre-Install Check: Confirm coupler condition, brake type, rating, and actuator series before ordering.
R&P Knowledge Hub
Compatibility: Designed as a service replacement inner member for compatible A-60 actuator housings.
Vehicle / System Fit: Hydraulic drum brake trailer systems using an A-60 style actuator setup.
Installation Notes: Existing outer housing must be reusable and compatible. Bleed the hydraulic brake system after installation.
Performance Insight: A properly matched inner member helps restore actuator movement, master cylinder operation, and trailer brake response.
Brand & Fitment Note
Selling Brand: A-60 style hydraulic brake actuator replacement inner member.
Application Reference: A-60 hydraulic drum brake actuator service replacement for compatible outer housings and 7,500 lb GVWR drum brake applications.
What This Means: This listing includes one complete inner member slide assembly only. It does not include the outer actuator housing, wheel cylinders, brake lines, backing plates, drums, or other axle brake components.
Before Ordering: Verify A-60 series compatibility, hydraulic drum brake configuration, 2" ball application, one-axle service needs, and 7,500 lb GVWR rating.
R&P Repair Insight
When replacing an actuator inner member, inspect the full brake system rather than treating the slide assembly as the only possible wear point. Brake fluid condition, line condition, wheel cylinders, and the outer housing can all affect braking performance.
- Bleeding: This actuator can be pressure-bled or manually bled through push-rod operation.
- Brake Type: This is for hydraulic drum brake systems, not disc brake systems.
- Housing Condition: Confirm the outer actuator housing is straight, secure, and not excessively worn before reuse.
