BRAKE SHOE ASSY REAR XCMG TRUCK CRANE QY25K
BRAKE SHOE ASSY REAR XCMG TRUCK CRANE QY25K
This brake shoe assembly is a crucial mechanism within the vehicle's drum brake system. Its primary function is to convert hydraulic pressure from the brake system into mechanical friction against the brake drum. When the brake pedal is engaged, the wheel cylinder pushes the brake shoes outward, pressing the friction lining against the rotating drum to decelerate the 25-ton capacity crane .
The assembly is specifically designed to fit the XCMG QY25K, ensuring a seamless replacement with performance that matches OEM specifications. Using genuine or high-grade aftermarket brake shoes is essential for maintaining the crane's stopping power, especially under heavy loads or on construction sites.

Pre-Installation Checklist
Inspect the brake drum for deep scoring or cracks; replace if necessary.
Ensure the wheel cylinder is not leaking and operates freely.
Clean the backing plate and lubricate the contact points with high-temperature brake grease.
Replacement Procedure
Safely lift the crane and remove the rear wheels.
Remove the brake drum.
Disconnect the return springs and the shoe-to-wheel cylinder connection.
Remove the old brake shoe assembly.
Install the new brake shoe assembly, ensuring the leading and trailing shoes are correctly oriented.
Reattach all springs and hardware using the appropriate tools.
After installation, the brake system must be bled to remove air and adjusted to ensure proper shoe-to-drum clearance .
Wear & Safety Tips
Brake shoes are a wear-and-tear component that must be inspected regularly .Check Regularly: Monitor the thickness of the friction material. Replace the shoes before the lining wears down to the steel backing.
Bedding-In Period: After installing new brake shoes, allow a "bedding-in" period for the friction material to mate with the drum surface. Avoid harsh braking during the first few hours of operation.
Safety First: As these components are vital for safety, always use parts that meet or exceed original equipment specifications .
Superior Durability: Manufactured with advanced friction materials to withstand high temperatures and heavy loads.
Precision Fit: Engineered specifically for the QY25K to ensure perfect alignment and maximum braking efficiency.
Reliable Stopping Power: Ensures safe, consistent braking performance critical for heavy machinery.
