Brake Pad Replacement: A Detailed Guide

Brake pad replacement is a common maintenance task that every car owner should be familiar with. Over time, brake pads wear down, reducing your car's braking performance and safety. Before you start, gather your tools: a jack, jack stands, a lug wrench, a wrench for the caliper bolts, new brake pads, and possibly a brake caliper compressor. First, park your car on a level surface and engage the parking brake. Loosen the lug nuts on the wheel you're working on. Use the jack to lift the car and secure it with jack stands. Remove the wheel and locate the brake caliper. Use the wrench to remove the caliper bolts. Carefully remove the caliper from the brake rotor and hang it out of the way, being careful not to stretch the brake line. Remove the old brake pads from the caliper. Use the brake caliper compressor to compress the caliper piston. Install the new brake pads into the caliper. Reinstall the caliper over the brake rotor and tighten the caliper bolts to the manufacturer's torque specification. Replace the wheel and tighten the lug nuts. Repeat this process for the other wheels. Always test your brakes after replacing the brake pads to ensure they're working correctly. Make sure you follow all the safety precautions and refer to your car's service manual for specific instructions and torque specifications. Replacing brake pads is a task you can handle yourself, saving you money on labor costs. Make sure you use the right tools, and double-check your work to ensure your safety.
