How to Replace Brake Pads — Step by Step

Replace worn brake pads at home in about 90 minutes per axle. Saves $150–$300 vs. a shop. This guide covers disc brakes — the standard on all modern passenger vehicles.

Time
About 90 minutes per axle.
Tools
Sockets, lug wrench, C-clamp or piston compressor, jack + stands, torque wrench, wire brush.
Parts
New brake pads, brake grease (slide pin lube), brake cleaner spray.

Safety note: Brakes are a safety-critical system. If you're not confident with any step, have a shop do it. A mistake here can mean brake failure at highway speed.

Step 1 — Loosen lug nuts before lifting

With the vehicle on the ground, break each lug nut loose by about one turn — don't remove them. Breaking them loose while the wheel is weighted keeps it from spinning.

Step 2 — Lift and secure the vehicle

Jack the vehicle at the manufacturer's specified lift points. Set it down on jack stands rated for your vehicle's weight. Remove the lug nuts and the wheel.

Step 3 — Remove the caliper

On the back of the caliper you'll see two slide bolts (usually 12mm, 14mm, or 17mm). Remove them. Slide the caliper off the rotor and hang it by a bungee or wire from the suspension arm. Never let the caliper dangle by the brake hose — you'll damage the hose.

Step 4 — Remove the old brake pads

Slide the old pads out of the caliper bracket. Note their orientation — inner vs outer, and any wear-indicator tabs. Clean the bracket with a wire brush and brake cleaner spray to remove rust and old pad dust.

Step 5 — Compress the caliper piston

The piston must be pushed back into the caliper to fit over the new (thicker) pads. Use a C-clamp or a dedicated piston compressor tool. Open the brake master cylinder reservoir first — fluid will push back as the piston retracts, and a sealed reservoir will resist the compression.

Warning for rear calipers on some vehicles: the piston must be rotated in as well as pushed. These need a special tool or cube adapter. Check your vehicle before attempting.

Step 6 — Install the new pads

Slide the new pads into the caliper bracket in the same orientation as the old ones. Apply a thin coat of brake grease to the back of each pad where it contacts the piston and caliper fingers. Never apply grease to the friction surface — it will ruin the pads.

Step 7 — Reinstall the caliper

Slide the caliper back over the pads and rotor. Clean the slide pins, grease them lightly with brake grease, and reinstall the slide bolts. Torque to manufacturer spec (typically 20–30 ft-lb — always check your specific manual).

Step 8 — Reinstall the wheel and lower the car

Put the wheel back on and hand-tighten the lug nuts. Lower the vehicle, then torque the lugs to spec in a star pattern. Typical passenger-vehicle spec is 80–100 ft-lb — check your manual.

Step 9 — Pump the brakes and bed-in the pads

Before driving, pump the brake pedal several times until it feels firm. The piston is fully retracted and needs to re-seat against the new pads. If you skip this step and drive off, your first pedal press will go to the floor.

For the first few miles, drive gently. A proper bed-in procedure extends pad life and prevents pulsing: perform 5 moderate stops from 30 mph, then 5 moderate stops from 45 mph, with cool-down between runs. This transfers an even film of pad material to the rotor.

Step 10 — Log the brake job in Trackara

In the Trackara app, log the brake pad replacement with date, mileage, pad brand (e.g., Akebono ProACT, EBC Yellowstuff), and part number. Set the next inspection reminder — pads typically last 25,000–70,000 miles depending on compound and driving style.

FAQ

Do I need to replace rotors when I replace pads?
Not always. If the rotors are within spec thickness, not warped, and not deeply grooved, new pads on old rotors is fine. If rotors are near minimum thickness (stamped on the rotor hat), warped, or grooved, replace them together. Replacing rotors at the same time is a common "while I'm in there" move.
Should I also bleed the brake fluid?
Not just from a pad change. But brake fluid should be flushed every 2–3 years regardless — it absorbs water over time, which lowers the boiling point and reduces brake performance under hard use.
What signs mean my brake pads need replacing?
Squealing during braking (wear-indicator tabs contacting the rotor), longer stopping distances, a grinding noise (pads are gone — you're into the metal backing plate), visible pad thickness under 3mm, or vibration under braking (warped rotors). Trackara can track pad mileage and alert before they're due.
