Step-by-Step Guide:
Step 1: Preparation
-Park your Blazer on a level surface and engage the parking brake.
-Loosen the lug nuts on the wheels but don't remove them completely.
-Use a jack to raise your Blazer until the tire is off the ground.
-Secure your Blazer with jack stands.
Step 2: Remove the Wheel
-Remove the lug nuts and take off the wheel.
Step 3: Remove the Caliper
-Locate the two bolts holding the brake caliper in place. These are usually located on the back of the caliper.
-Use a ratchet and socket to remove the bolts.
-Once the bolts are removed, gently lift the caliper off the rotor.
-Hang the caliper out of the way using a piece of wire or bungee cord. Be careful not to let it hang from the brake line.
Step 4: Remove the Old Brake Pads
-Inspect the old brake pads for wear. If they are less than 1/4 inch thick, they need to be replaced.
-Use a flat-head screwdriver to pry the brake pads out of the caliper.
Step 5: Clean the Caliper
-Use a wire brush to clean the caliper. Remove all dirt, debris, and rust.
-Spray the caliper with brake cleaner to remove any remaining dirt.
Step 6: Apply Caliper Grease
-Apply a thin coat of caliper grease to the caliper pins and where the brake pads will contact.
Step 7: Install the New Brake Pads
-Place the new brake pads into the caliper.
-Make sure that the pads are seated properly.
Step 8: Reinstall the Caliper
-Reattach the caliper to the rotor by sliding it back into place.
-Install the two bolts and tighten them securely.
Step 9: Reinstall the Wheel
-Put the wheel back on and hand-tighten the lug nuts.
-Lower the Blazer using the jack.
-Tighten the lug nuts with the ratchet and socket.
10: Test the Brakes
-Pump the brake pedal several times to get a firm pedal.
-Test the brakes by driving your Blazer around a safe area. Make sure the brakes work properly.
Tips:
-Before you start working on the brakes, inspect them for leaks or other damage. If there are any issues, have them repaired by a qualified mechanic.
-Make sure you use the correct size and type of brake pads for your vehicle. Using the wrong pads can damage your brakes.
-Be careful not to get brake fluid on your skin. Brake fluid is harmful to your health.
-Wear safety glasses to protect your eyes from brake dust and flying debris.
