The brakes system can exert as much as 1,000 pounds (450 kg) of hydraulic pressure on each of the four brakes.What It DoesThe Brake System applies frictional force to the wheels to slow or stop the vehicle.Service & MaintenanceThe following inspections and maintenance procedures can help prevent potential brake problems:Check brake fluid level at every oil change.  Replace fluid according to Owner's Manual recommendations.Calipers and wheel cylinders should be checked every brake inspection and serviced or replaced as required.Inspect the brake lines for rust, punctures or visible leaks (you may be able to do this, but consult a qualified technician if necessary)The following should be conducted by a qualified technician:Inspection of the brake hoses for brittleness or crackingInspection of brake lining and pads for wear or contamination by brake fluid or greaseInspection of wheel bearings and grease sealsParking brake adjustments (as needed)New DuraStop rotors DO NOT need machining.Used rotors can be machined provided minimum thickness can be maintained:Before you machine rotors, make sure the lathe is clean, within specs and has sharp tool bits.After completing the finish cut, sand both sides of the rotor for one minute per side using a sanding block and 130- to 150-grit sandpaper to obtain a non-directional finish.After sanding, wash the rotor with dish soap and water. DO NOT clean the rotor with brake cleaner/solvent-based product.Thoroughly clean the calipers, caliper slides and hardware. Remove all dirt, rust and grease.Great brake pad performance at a great value.
