Product Code:SAE J1570
Title:Rubber Dust Boots for the Hydraulic Disc Brake Piston
Issuing Committee:Automotive Brake And Steering Hose Standards Comm
Scope: This SAE Standard covers molded rubber boots used on disc brake pistons to prevent the entrance of dirt and moisture which could cause corrosion and otherwise impair caliper operation. The specification include performance tests of brake piston boots of both plain and insert types under specified conditions and does not include requirements relating to chemical composition or physical properties of the rubber compound. Further, it does not cover the strength of the adhesion of rubber to the insert material where an insert is used. The rubber material used in these boots is classified as suitable for operating in a temperature range of -40 to +120 degrees C +/- 2 degrees C (-40 to +248 degrees F +/- 3.6 degrees F).
