Blow it out with no compressed air, do not inhale any of it. A filtering mask that was approved must be used in the brakes. Never under any circumstances apply petroleum based solvents to clean brake parts but instead apply brake system cleaner. The rear calipers are also complex and therefore overhauling them is not advisable. To replace them as a couple with re-built units will offer a better service at a lesser cost. The caliper may be removed by first loosening the lug nuts at the rear of the wheel and then lifting the rear of the vehicle and firmly holding it on jackstands before taking the wheel out. The second step is to pull out the
Parking Brake Cable of the caliper, and then the brake hose by taking out the banjo bolt and inserting the hose to ensure nothing contaminates it and least amount of brake fluid is lost. Take out the rear disc manual adjustment gear plug then rotate the manual adjustment gear counterclockwise bring the brake caliper piston nearer. Unscrew lower caliper mounting bolt and in 1994 and newer models, the upper mounting bolt as well and then strip the caliper off the bracket. To fit, use the opposite process by which the installation was done, with the addition that the copper sealing washers should be replaced at the end of the brake hose into the caliper fitting. Rotate the manual adjust gear clockwise until the
Brake Pads touch the brake disc, then rotate it 1/3 clockwise, replace the plug, and screw it back on. Lastly, drain the brake system, making sure there are no pipes in the hose attachments, and look at brakes too, before putting the car back in its regular operation.
