JCB Brake Piston Compression / Adjustment Spring - 10/301319
The brake piston compression spring is a component of the wet (oil-immersed) braking system used in JCB machinery. It is responsible for maintaining the correct distance and tension of the brake piston, ensuring a rapid return of the piston to its starting position after releasing the brake pedal, and allowing for precise system adjustment.
Technical Specification:
- Function: Compression and brake piston return adjustment.
- Compatibility: Works with the adjustment bolt, part number 336/F0846.
- Operating Environment: Hydraulic and transmission oils.
Compatibility with JCB Machinery:
| Machine Category | Models and Variants |

Workshop Tip: During axle servicing and brake disc replacement, always check the condition of the compression springs. Worn or overheated springs lose their characteristics (clamping force), which can lead to brake "dragging," disc overheating, and faster wear of the entire system. When replacing the springs, it is also recommended to inspect the adjustment bolt for thread damage.
