Inspecting and replacing your Cadillac brakes is a simple task, and one that may save your life. So at the first sign of wear and tear, check your Cadillac brakes. Normally, the job first requires inspecting the mechanical, hydraulic, and electrical components in both the front and rear brakes. If necessary, replace the front and rear pads or shoes, or the brake rotors or discs. You should also inspect wheel bearings, and in older models, you must repack those bearings. It's a good practice to lubricate all critical areas such as caliper slides and shoe pads with moly-based high temperature brake grease at that point. Then, check and adjust the parking brake. Replace the Cadillac brake fluid, if the levels are low. Bleed the brake lines to remove trapped air. Look for leaks in the hoses, lines, wheel cylinders, calipers and master cylinder, and see if there are any cracks, bulges, or damage to the hoses. While you are there, look at the calipers and wheel cylinders for leaks, severe corrosion or damage. Does the brake pad wear sensor show cracks or damage? Then, make sure you do not see any warning lights or trouble codes for the ABS system, if you have one. After all that work on your Cadillac brakes, take it for a test drive to make sure the new parts are working smoothly.
