To change brake pads, start by parking on level ground and engaging the parking brake. Jack up your vehicle, secure it with stands, and remove the wheel. Loosen the caliper bolts, pivot it up, and slide out the old pads. Inspect the rotor for wear, clean components, then install new pads with brake grease. Reassemble, tighten lug nuts, and check fluid levels. Stick around to uncover deeper insights into perfecting this task.

Preparing for Brake Pad Replacement
Before diving into brake pad replacement, make sure you’ve got everything set for a safe and efficient process. Start with level ground preparation by parking your vehicle on a flat surface to guarantee stability. Engage the parking brake firmly and place wheel chocks for added security.
If your manual advises, perform battery disconnection to eliminate electrical risks during the job. Don’t skip wearing safety gloves and eye protection to shield against brake dust. Ensure you work in a well-ventilated area to avoid inhaling harmful fumes or dust during the process. Having a caliper spreader tool ready will make compressing the brake pistons much easier.
Next, gather your tools—jack, jack stands, lug wrench, and socket set. Check your brake pads and rotors for wear, and review the service manual for specific torque specs. Verify replacement pads match your vehicle’s specs. Finally, organize your workspace with brake cleaner and adequate lighting for precision. This DIY approach can save you considerable money compared to professional service costs.
Removing Wheels and Caliper
With your workspace prepped and tools at the ready from the earlier steps, it’s time to tackle removing the wheels and caliper to access the brake pads.
Start by positioning the jack at the vehicle’s lift points, raising it, and securing it with jack stands. Remove the lug nuts, pull off the wheel, and set it aside safely.
Next, focus on the caliper. Using the correct socket, loosen and remove the caliper bolts, ensuring brake line safety by avoiding any kinks or twists. Before removing the caliper completely, slightly loosen the banjo bolt to minimize brake fluid loss. Swing the caliper up, securing caliper mounting with a wire or clamp to hold it without stress on the lines. Pay close attention to the caliper bracket as it’s essential for maintaining proper pad alignment with the rotor. Check for clearance around the rotor, and you’re set to proceed. Remember, this process of removing the caliper is crucial as it allows you to inspect brake pads and replace them if necessary.
Extracting Old Brake Pads
After securing the caliper out of the way, dive right into extracting the old brake pads with a keen eye for detail. Pivot the caliper upwards to expose the pads, ensuring you’ve supported it with a bungee cord to avoid strain on the brake hose. Check the pistons for alignment and cleanliness, then release the retaining clips holding the old pads in place. Carefully slide the pads out of their slots in the caliper bracket. If they’re stuck, use a flathead screwdriver to pry them free with precision. Be sure to wear gloves to protect your hands from grease and debris during this process. Double-check the mounting bolt torque when working near the caliper bracket to ensure proper specifications are maintained. Take note of the tension tab placement as you remove the old clips to ensure proper orientation during new clip installation.
During this brake system inspection, examine the old brake pads for uneven pad wear patterns, as this could signal deeper issues like caliper misalignment requiring further attention. Handle the old pads properly for disposal.
Inspecting and Cleaning Components
Several critical steps await as you dive into inspecting and cleaning your brake components to guarantee ideal performance. Start with a thorough brake rotor surface inspection, checking for cracks, grooving, or excessive wear. Measure rotor thickness to confirm it meets specs, and use a wire brush to clear debris.
Next, examine calipers for smooth movement, rust on slides, and hydraulic leaks. Clean around them with a soft brush, ensuring no contamination. For maximal safety during inspection, ensure calipers are securely supported while checking components. Additionally, ensure that the brake pedal movement is smooth and fully depresses to confirm proper caliper function brake pedal movement. Watch for any spongy pedal feel that could indicate collapsed brake hoses acting as check valves.
Don’t overlook brake hoses—look for cracks or brittleness and clean connections with compressed air. Verify brake fluid cleanliness in the reservoir, ensuring it’s free of contamination, and wipe up any spills immediately. Finally, inspect wheel bearings for play and clean them meticulously to maintain smooth operation.
Installing New Brake Pads and Reassembling
Now that you’ve thoroughly inspected and cleaned the brake components, it’s time to move on to installing new brake pads and reassembling the system. Start by aligning the new pads with the caliper notches, seating one tab and rotating them into place. Apply brake grease to the pad backs for smooth operation. Guarantee compatibility with your vehicle’s system. Ensure that the inside and outside pads are correctly shaped for their specific positions correct pad shapes. Using manufacturer-grade parts will help ensure optimal brake performance and longevity. Remember that brake pads must be installed in paired sets for proper braking function.
Next, focus on securing the caliper by compressing the piston with a suitable tool. Pivot the caliper into position over the rotor, aligning it properly, and tighten the slider bolts to the specified torque.
When reassembling the brake assembly, inspect the wheel hub for debris, reinstall the wheel, and tighten lug nuts in a star pattern. Finally, check brake fluid levels.
