ATB Novoflex Instructions:
- Choose the Flexible Honing Tool for the specific hole size. The actual NovoFlex tool will be approximately 10% larger than the hole size.
- Use 10-30 weight oil for honing lubrication, when honing hydraulic brake cylinders, use hydraulic brake fluid as a honing lubricant.
- Have the NovoFlex Flexible Honing Tool rotating upon entry and removal from the bore.
- Recommended RPM range for the NovoFlex Tool is 100 to 1200 RPM, based on the brush diameter. Air tools are not recommended.
- Use 60-120 strokes per minute depending on the RPM. Final stroking may be accelerated to develop a 45° cross-hatch angle.
- Honing time should be 20/45 seconds per bore.
- Do not use solvents for honing or cleaning.
- Clean cylinders after honing with warm or hot water and detergent using an Osborn plain nylon brush, and then lightly oil the bore.
