Knowing how to replace brake pads is essential for every car owner. Brake pads are one of the most critical components of your vehicle’s braking system, ensuring your car stops safely and efficiently.
In this guide, we’ll explain how to replace brake pads, show you signs of wear, provide step-by-step replacement instructions, offer maintenance tips, and cover costs and types of brake pads.
What Are Brake Pads?
Brake pads are a part of your disc brake system. They press against the brake rotors to create friction, slowing down your vehicle. Over time, brake pads wear down due to friction and need replacement to maintain safe braking performance.
Signs of Worn Brake Pads
Knowing the signs of worn brake pads can help you prevent accidents and expensive repairs:
- Squealing or screeching noises: Often caused by a metal wear indicator on the pads.
- Grinding sounds: Indicates pads are completely worn and metal is contacting the rotor.
- Longer stopping distances: Brakes feel less responsive than usual.
- Vibration or pulsation: Felt through the brake pedal when stopping.
- Brake warning light: Some vehicles have sensors to alert low brake pad thickness.
How to Check Brake Pad Wear
Checking your brake pads regularly is part of routine brake maintenance:
- Visual Inspection: Look through the wheel spokes to see the brake pads. If the pad thickness is below 3mm, it’s time to replace.
- Listen for Noises: Squealing or grinding indicates wear.
- Monitor Stopping Distance: If your car takes longer to stop, inspect the brake pads.
- Check Brake Fluid: Low brake fluid can indicate worn pads in some vehicles.

Step-by-Step Brake Pad Replacement Guide
Replacing brake pads yourself can save money, but only if done safely. Here’s a step-by-step guide for disc brakes:
Tools Needed:
- Jack and jack stands
- Lug wrench
- C-clamp or brake caliper tool
- Socket set
- New brake pads
- Brake cleaner
- Gloves and safety glasses
Step 1: Lift the Vehicle
- Use a jack to lift the car and secure it with jack stands.
- Remove the wheel with a lug wrench.
Step 2: Remove the Caliper
- Use a socket to remove the caliper bolts.
- Carefully slide the caliper off the rotor. Do not let it hang by the brake line.
Step 3: Remove Old Brake Pads
- Slide out the old pads from the caliper bracket.
- Inspect the rotors for grooves or damage.
Step 4: Install New Brake Pads
- Apply brake grease to the backing plate of the new pads.
- Slide new pads into the caliper bracket.
- Use a C-clamp to compress the caliper piston if necessary.
Step 5: Reinstall the Caliper and Wheel
- Reattach the caliper over the new pads.
- Tighten bolts to manufacturer torque specifications.
- Reinstall the wheel and lower the vehicle.
Step 6: Test Brakes
- Pump the brake pedal a few times before driving to seat the pads.
- Test drive at low speed to ensure proper braking.

Brake Pad Types
Brake pads come in different materials, each with pros and cons:
- Organic Brake Pads: Quieter, less expensive, but wear faster.
- Semi-Metallic Brake Pads: Durable and good performance but slightly noisier.
- Ceramic Brake Pads: Long-lasting, quiet, minimal dust, but more expensive.

Brake Pad Maintenance Tips
Regular brake maintenance can extend pad life:
- Inspect pads every 10,000 miles.
- Avoid heavy braking when possible.
- Keep rotors clean using brake cleaner.
- Rotate tires regularly to reduce uneven wear.

Brake Pad Replacement Cost
Brake pad replacement costs vary depending on vehicle type and pad material:
- Standard cars: £50–£100 per axle
- SUVs and trucks: £80–£150 per axle
- Premium or ceramic pads: £120–£250 per axle
Labor costs vary if replacing at a garage, but doing it yourself can save money.
