KTM Brake Caliper Cooler Fits: Rear Brembo System Models: KTM 2004 - 2009 125-200 SX EXC 250-300 SX EXC MXC 250 SXF 400-450-525 XS SX EXC 450-525 SMR The Calliper Radiator Kit fits “in line” at the rear Calliper with the supplied Banjo Bolt, Seal Washers and fittings. As the system temperature rises it is not able to dissipate heat fast enough. As the heat rises, your feel or modulation suffers. If the brake fluid reaches the boiling point Major brake fade sets in. The kit allows Brake Fluid to Cycle in and out of the radiator with each push of the brake pedal. With this action the Radiator dissipates heat from the Brake Fluid. Heat is also drawn from the Calliper Casting by the Radiator, as it is tightly fixed to it. Material/Finish: Radiator (6061 Alu. Orange Anodise), Banjo Bolt 4130 Chrome Molly Steel
