⚠️ Safety Warnings
Important safety information - read before proceeding
- •Ensure the vehicle is on a flat surface and use wheel chocks to prevent rolling. Always wear safety glasses and gloves.
- •Use the jack to lift the front or rear of the vehicle, depending on which brake pads are being replaced.
- •Secure the vehicle with jack stands to ensure stability.
- •Loosen the lug nuts using a lug wrench while the vehicle is still on the ground.
- •Remove the lug nuts completely and take off the wheel to expose the brake caliper.
- •Locate the caliper mounting bolts and remove them using a socket wrench.
- •Lift the caliper off the brake rotor. Support the caliper with a piece of wire or hang it to avoid stressing the brake line.
- •Slide the old brake pads out of the caliper bracket. Take note of how they are positioned for proper installation of the new pads.
- •Use a C-clamp to compress the caliper piston back into the caliper housing. This will create enough space for the new, thicker brake pads.
- •Inspect the piston for any signs of damage or corrosion.
- •Apply a small amount of brake pad grease to the backing of the new pads (avoid the friction surface).
- •Slide the new brake pads into the caliper bracket in the same orientation as the old ones.
- •Position the caliper back over the new brake pads and align it with the mounting holes.
- •Tighten the caliper mounting bolts to the manufacturer’s specified torque (usually around 25-30 Nm).
- •Place the wheel back onto the hub and hand-tighten the lug nuts.
- •Lower the vehicle off the jack stands and onto the ground.
- •Tighten the lug nuts to the specified torque (usually around 120 Nm) in a star pattern for even distribution.
- •Before driving, pump the brake pedal several times to ensure the brake pads are seated properly.
- •Check for any leaks around the caliper or brake fluid reservoir.
- •Test drive the vehicle at low speeds to ensure proper brake function.
- •Listen for any unusual noises when braking.
- •Check the dashboard for any brake warning lights.
- •Inspect the brakes visually for any signs of miss-alignment or improper installation.
- •Regularly inspect brake pads and rotors for wear.
- •Follow the manufacturer’s maintenance schedule for brake service.
- •Use high-quality brake pads and components for replacements.
- •Monitor brake fluid levels and replace fluid as needed.
Symptoms
- •Squeaking or grinding noise when braking
- •Vibration or pulsation in the brake pedal
- •Reduced braking efficiency
- •Warning light for brake pads illuminated on the dashboard
