Calipers Technical Information

Materials

• The calipers are machined from aluminium alloy and have a clear, hard anodised finish for protection.
• The pistons are also manufactured from aluminium alloy and are coated with TUFRAM. This specialised aluminium coating combines the hardness of aluminum-oxide ceramic with the properties of selected proprietary polymers, providing aluminum parts with new levels of hardness, wear and corrosion resistance, and permanent lubricity.
• Any caliper carrier supplied is made from the same material as the calipers.

Fitting and maintenance

• All calipers use a standard banjo bolt fitment for brakes lines of M10x1.25mm.
• The brake pads are held in position using a pin and 'R' clip system. This simple yet effective method makes it easy to change pads quickly.
• The majority of calipers come supplied with large, hard anodised bleed bolts with a separate, removable bleed nipple.
• Virtually all parts of the caliper are replaceable, making them a cost effective solution.
• In some cases, the calipers are direct replacements for standard discs and forks, but if not, mounting brackets can be provided to suit both standard and oversized disc sizes.
• Detailed dimensional diagrams are available on request.

Master cylinder requirements...

If you are upgrading to bigger calipers, you need to ensure that your master cylinder can cope with the increased pad area to get the full braking improvement. For ISR calipers, see the table below for guidance on required master cylinder bore size for front brakes.
