RotorVISUAL INSPECTIONCheck rotor for roughness, cracks or chips.RUNOUT1.Secure rotor to wheel hub with at least two nuts (M12 x 1.25).2.Check runout using a dial indicator.Make sure that wheel bearing axial end play is within the specifi-cations before measuring runout. Refer to FAX-5, "FRONTWHEEL BEARING".3.Change relative positions of rotor and wheel hub so that runoutis minimized.4.If the runout is still out of specification, turn rotor with on-carbrake lathe (“MAD, DL-8700”, “AMMCO 700 and 705” or equiva-lent).WFIA0029EMaximum runout: 0.07 mm (0.0028 in)SBR219C

Use extreme caution.1.Drive the vehicle on a straight smooth road at 50 km/h (31 MPH).2.Use medium brake pedal/foot effort to bring the vehicle to a complete stop from 50 km/h (31 MPH).Adjust brake pedal/foot pressure so that vehicle stopping time equals 3 to 5 seconds.3.To cool the brake system, drive the vehicle at 50 km/h (31 MPH) for 1 minute without stopping.4.Repeat steps 1 to 3, 10 times or more to complete the burnishing procedure.

Do not blow with compressedair.●While the brake pad and cylinder body are separated, the piston may suddenly jump out, so do notdepress the brake pedal.●It is not necessary to remove bolts on torque member and brake hose except for disassembly orreplacement of the caliper assembly. In this case, hang cylinder body with a wire so that brakehose is not under tension.●Do not damage piston boot.●If any shim is subject to serious corrosion, replace it with a new one.●Always replace shims and shim covers as a set when replacing brake pads.●Keep the rotor clean of brake fluid.1.Union bolt2.Copper washer3.Brake hose4.Sliding pin bolt5.Sliding pin6.Cap7.Air bleeder8.Cylinder body9.Sliding pin boot10.Piston seal11.Piston12.Piston boot13.Torque member14.Inner shim cover15.Inner shim16.Inner pad17.Pad retainer18.Pad retainer19.Outer pad20.Outer shim21.Outer shim cover22.
