What You Will Need to Replace Brake Pads at Home
The parts list is short. Pick up the correct pad set for your exact make-model-year; check the part finder on any major auto-parts site. You will also need:
- Safe jack stands rated for curb weight plus 50 %
- OEM jack to get the car up, then stands take over
- Wheel chocks for the axle that stays on the ground
- 17 mm or 19 mm lug wrench (size varies)
- Socket set with ratchet & 6-inch extension
- C-clamp or dedicated caliper wind-back tool
- 12-inch bungee cord to hang the caliper without stressing the hose
- Brake cleaner spray and rags
- High-temp brake grease (never regular grease or WD-40)
Have nitrile gloves and a small tray to keep hardware organized. An old cookie sheet works. Total tool cost under $40 for the common sockets and one C-clamp. Most garages already own the jack stands and cleaner.
Before You Start: Safety, Parking Surface, and Torque Values
Work on level concrete. Loose gravel or asphalt softens under hot brake parts and the jack can tilt. Confirm curb weight in the owner’s manual, then set stands at the official pinch-weld points. A Ford Focus sees about 2,900 lb; a Toyota Camry about 3,300 lb. Always stay below rated capacity.
Brake work relies on one critical number: wheel-lug torque. Typical passenger cars use 80-100 ft-lb. Buy a dial-type torque wrench if you do not already own one. Over-tightened lugs warp rotors; under-tightened lugs come loose. Write the spec on a piece of masking tape and stick it on the fender.
Step 1: Loosen Lugs & Secure the Vehicle
Break each lug a quarter-turn before lifting the car. Place chocks behind the rear wheels if you start with a front-axle lift. Chock the front if you begin with the rear.
Jack the corner until the tire is clear by two inches, then slide a stand under the factory point. Lower the jack so load rests on the stand, not the hydraulics.
Step 2: Remove the Wheel & Inspect Existing Hardware
The full caliper sits inside the rotor “hat.” Look for uneven pad wear patterns: inner vs outer, tapering, or glazing. Cracked rotor faces or visible scoring indicate rotors need machining or replacement. Clean these inspection surfaces now with brake cleaner to avoid breathing dust later.
Step 3: Open the Caliper Assembly
Two slider bolts hold the caliper bracket to the assembly. On many Japanese cars the bolts are 12 mm or 14 mm; German cars often use Torx T40 or Allen 7 mm. Remove only the caliper carrier bolts, not the larger bracket-to-knuckle bolts unless you swap rotors.
Once loose, push the caliper upward or outward to clear the outer pad. Tie it gently to the coil spring with a bungee. Never let the caliper hang by the rubber hose.
Step 4: Remove the Old Pads & Retainer Clips
Pads usually slide out of sheet-metal ears. Make note of small anti-rattle clips or shims—the new pads reuse some of these. Snap a quick photo with your phone; it prevents mix-ups on reassembly.
Step 5: Compress the Caliper Piston
Open the master cylinder reservoir cap and pad a towel around it; this catches overflow when you push the piston back. Align the C-clamp over the old pad and caliper body, then turn slowly. Pressure should build evenly. If the piston cocks to one side, reposition and try again.
Some rear calipers use a threaded screw-type piston requiring the caliper tool. Twisting clockwise compresses and resets the parking-brake self-adjuster.
Step 6: Prep New Pads & Hardware
A quick swipe of high-temp grease on the metal backing plates prevents squeal. Do not let the compound touch the friction material. Most copper-based anti-seize works, but dedicated brake paste stays put above 400 °F. Re-install any stainless shims exactly as they came off; they control thickness and locate the pad ears.
Step 7: Install the New Pads & Re-Mount the Caliper
Drop the outer pad into the bracket ears, then the inner, aligning the clips. Slide the caliper over the new pads so the piston lines up. Tighten the slider bolts to the spec—usually 22-30 ft-lb. If you use a regular ratchet, “snug plus a quarter-turn” is close enough, but mark a note to revisit with a torque wrench when you next rotate tires.
Step 8: Bleed and Top Off Brake Fluid (Optional but Smart)
If you cracked the bleed screw to reset the piston, bleed one corner until new, clear fluid flows out. Keep the master cylinder above the minimum line at all times. Old fluid turns the color of coffee; it absorbs moisture and lowers boiling point. One small bottle of DOT 3 or DOT 4 costs less than $5 and is money well spent.
Step 9: Re-Install the Wheel & Torque in a Star Pattern
Wipe rotors clean with brake cleaner to remove oily fingerprints. Spin the wheel to ensure no pad drag. Lower the car completely, then tighten lugs in a cross pattern with the torque wrench until you hear the click. Roll forward a few feet and double-check lugs once more.
Step 10: Bedding Procedures Matter: 10 Cycles from 35 to 5 mph
Factory engineers from Brembo and Akebono recommend 10 moderate stops from 35 mph down to 5 mph with 30-second cool-downs between. This heats the pads and rotors evenly, transferring a consistent film that prevents green-pad glaze. Do NOT brake hard during this set; hard stops before bedding can glaze and lead to squeal for life. Allow at least 200 miles of light city driving before full-throttle use.
DIY Cost vs Shop Labor: Real Numbers
A quick price check on July 18, 2025, shows:
- Quick-lube chain shop front pad change: $280 (includes pads and labor)
- Independent garage quote: $195-225 (mid-grade pads)
- OEM parts alone online: $55-80 (ceramic pads)
- Your 90-minute labor: free, plus $8 in brake cleaner & grease
Savings of roughly 60-70 % are typical for four-wheel-drive and large SUVs where shops charge premium labor.
Warning Signs to Watch After Installation
- Squeal immediately after bed-in: usually a missed shim or lack of grease on ears
- Grinding after 50 miles: rotor run-out or loose lug nuts
- Pedal sinks to floor: air in lines (bleed again) or internal caliper bypass
- Pull to one side under braking: uneven pad thickness or caliper slider stuck
- Slight burn odor first 20 miles is normal; strong smoke is not—pull over and check pistons
Making the Job Faster on Your Second Car
If you change a second vehicle, borrow or buy a cordless impact driver with 17 mm socket. Lug removal drops from 3 minutes per wheel to 15 seconds. Reuse the same brake-clamp: the 4-inch size fits almost everything. Keep a loop of stainless safety wire in the tool box to secure caliper clips if they vibrate loose on older cars.
When to Replace Rotors Too
Rotors have a minimum thickness cast into the edge, usually printed in millimeters. Typical sedan rotors start around 25 mm new; discard at 22 mm. If you feel a steering-wheel pulse that started before the pad change, rotors are warped and turning or replacement is the fix. Turning costs $15 per rotor at most parts stores, but below discard thickness replacement is mandatory.
Storage & Environment Notes
Brake fluid absorbs water from humidity, so keep the cap closed. Brake parts hate grease on friction areas—keep a separate tray for oily tools versus clean ones. Store half-used cans of brake cleaner upside-down; the propellant stays inside, extending shelf life.
