Diagnostic Steps

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, C-clamp, brake cleaner, and safety goggles.
Ensure vehicle is parked on a level surface and the engine is off.
Wear safety goggles and gloves.

2. Lift the Vehicle

Loosen the lug nuts on the front or rear wheel where brake pads will be replaced.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel by fully unscrewing the lug nuts.

3. Remove Brake Caliper

Locate the caliper bolts (usually two) on the back of the caliper.
Use the socket set to remove these bolts and carefully slide the caliper off the brake rotor.
Support the caliper using a bungee cord or similar to avoid stressing the brake line.

4. Remove Old Brake Pads

Inspect the old brake pads and note their orientation.
Slide the pads out of their mounting brackets. If necessary, use a flathead screwdriver to gently pry them loose.
Take note of the wear indicators, if any, for proper placement of new pads.

5. Compress the Caliper Piston

Use a C-clamp to compress the caliper piston back into the caliper housing. This creates space for the new, thicker brake pads.
Ensure the piston is fully retracted and check the condition of the piston seal.

6. Install New Brake Pads

Apply a thin layer of brake grease on the back of the new pads to prevent noise.
Position the new pads into the caliper brackets in the same orientation as the old ones.
Ensure the wear indicators are properly aligned.

7. Reattach the Caliper

Carefully slide the caliper back over the new pads.
Reinsert and tighten the caliper bolts to the manufacturer's torque specifications (usually around 25-30 ft-lbs, verify with service manual).

8. Reassemble Wheel and Lower Vehicle

Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle using the jack and remove the jack stands.
Fully tighten the lug nuts in a crisscross pattern to the recommended torque (typically 80-100 ft-lbs).
