Shimano 1052c Coned Disc Spring

Product Description

The SHIMANO 1052c is a coned disc spring designed for use in Shimano disc brake systems. This small but critical component maintains consistent clamping pressure and spring tension within the brake assembly, ensuring reliable pad retraction and brake feel. It is typically installed by bicycle mechanics and service technicians during brake caliper overhauls or component replacement. The coned profile allows the spring to flex under load and return to its original shape, maintaining proper caliper function over repeated brake cycles.

This coned disc spring is suited for service and maintenance applications where the original spring has fatigued, deformed, or been lost during a caliper rebuild. It is a direct OEM-style replacement part intended to restore factory brake performance in Shimano disc brake calipers.

Key Features

• Coned disc profile delivers consistent spring tension and pad retraction force
• OEM-style replacement restores factory brake caliper function
• Compact form factor fits within the brake caliper assembly without modification
• Engineered for durability through repeated brake cycles

Compatibility

Designed as an OEM-style replacement coned disc spring for Shimano disc brake caliper assemblies. Refer to the Shimano dealer manual or exploded parts diagram for your specific caliper model to confirm fitment before installation.

Installation Notes

Installation should be performed by a qualified bicycle mechanic familiar with Shimano disc brake caliper service procedures. Fully release brake pressure and remove the wheel before disassembling the caliper. Consult the applicable Shimano dealer technical document for the correct spring orientation, as incorrect installation can result in reduced braking performance. Follow all manufacturer service guidelines when reassembling the caliper.
