ISR Brakes from Sweden are very high quality and rugged systems designed for top racers who demand the best performance and durability from their brake systems.  Race proven, all ISR brake systems are CNC machined from aerospace quality billet aluminum and then finished with a clear anodized coating for the ultimate in corrosion protection.  The 4 piston CNC machined calipers from ISR have the highest strength to weight ratio of any aftermarket caliper today.  


The 22-048-OD monobloc calipers are designed for BMW rear brake applications with 94mm spacing.  The calipers are extremely light weight and feature a solid monobloc design that minimizes flex.  The four individual pads allow more edges to bite into the disc resulting in an extremely high friction characteristic.  Each pad has its own machined pocket that allows for pad retention in the event of pad pin failure, a feature designed as a direct result of Swedish Superbike racing involvement.


The caliper pistons are machined from an aluminum alloy for light weight and are then plated with a very hard Tufram coating designed to minimize wear from long piston life under the most demanding conditions.  The 22-048-OD monobloc calipers have the following specifications for motorcycles 94mm axial mount bolt centers and 150mm-250mm rotors:

• 25mm x4 pistons
  
• Pistons are made from a Tufram plated aluminum alloy
  
• Pad area is 20.9 square centimeters
• Swept height of rotor is 27mm
• 150mm - 280mm rotor size
  
• Rotor thicknesses 4.6mm-5mm
• Banjo bolt size M10 x 1.25mm
• 94mm axial mount centers
  
• 0.46kg (1.76lb) weight
  
• Clear anodized

Calipers are sold each.  As always please check the dimensions and measure carefully, verify the calipers will fit before purchasing.
