Lisle 50600 GM Single Brake Release Tool
- Releases Tension on Both Large and Small GM Single Spring Brakes During Servicing.
- Many GM brakes use a heavy single spring.
- The 50600 engages the spring and quickly releases the spring tension.
- The brake can then be disassembled to replace brake shoes, emergency brake cable or service the brake cylinder.
- Supersedes our 49900 which works on the small spring
