How to Change Brake Pads
Changing front brake pads is one of the more approachable jobs on a car — two bolts, a caliper, a piston to compress, and a couple of hours. It is also a braking system, so the standard for getting it right is different from the standard for an oil change.

Two honest caveats before you start. Rear brakes on many modern cars have an electronic parking brake, and the caliper pistons must be retracted electronically before the pads can come out — without a suitable scan tool you will not get the job done, and forcing it damages the motor. And if you are not confident torquing wheel fasteners or compressing a piston, this is a job worth paying for. There is no shame in that and a great deal of downside in the alternative.
What You Need
- Brake pads for your exact vehicle: there is no universal brake pad. Confirm year, make, model, trim and brake package — our brake pads guide, or check on Amazon
- Rotors, if yours are worn: measure against the minimum thickness stamped on the rotor before deciding — our brake rotors guide, or check on Amazon
- Jack stands: non-negotiable. A jack lifts, stands hold, and you will be under the car — our jack stands guide, or check on Amazon
- A torque wrench: caliper bolts and wheel nuts both have specifications, and both matter here — our torque wrench guide, or check on Amazon
Changing Front Brake Pads, Step by Step
Check whether this job is the one you think it is
Front pads on most cars are straightforward. Rear pads on a car with an electronic parking brake are not — the caliper pistons are driven by small motors that must be retracted with a scan tool before the pads will come out. Winding them back by hand damages the mechanism.
Check which you have before ordering parts. If your handbrake is a button rather than a lever, assume electronic and confirm you have a tool that supports your car, or leave the rears to a shop.
Loosen the wheel nuts, then lift and support
Crack the wheel nuts loose while the car is on the ground. Then lift at the manufacturer's jacking point, lower onto jack stands, and shake the car firmly before going anywhere near it. Chock the wheels that remain down.
Slide the removed wheel under the sill as a last-resort backstop. Work on level concrete, never on a slope or soft ground.
Remove the caliper, and support its weight
The caliper is held by two bolts on the back, often behind rubber dust caps. Undo them and slide the caliper off the rotor. It will still be attached by the flexible brake hose.
Do not let it hang on that hose. The hose is not a structural component and stretching it damages the inner lining in a way you cannot see. Hang the caliper from the spring with a bungee or a length of wire.
Take the old pads out and inspect everything
The pads lift out of the carrier, usually with anti-rattle clips. Note how they sit — take a photograph. Compare their thickness to the new ones so you can see how much was left.
Now inspect the parts nobody looks at. The caliper slide pins should move freely and be greased; seized pins are the most common cause of pads wearing unevenly and are worth fixing while you are here. Check the rubber boots for splits and look at the rotor for scoring or a pronounced lip at its outer edge.
Compress the piston slowly
New pads are thicker, so the piston has to go back into the caliper. Use a C-clamp or a proper piston tool, pressing against the old pad so the load spreads across the piston face rather than a single point.
Open the brake fluid reservoir cap first and watch the level as you push — fluid is being displaced back up the line and an already-full reservoir can overflow. Go slowly. Forcing it fast can damage the piston seal.
Fit the new pads and grease the right places
Clean the carrier where the pads sit, fit the new anti-rattle clips if supplied, and slide the pads in the same orientation as the old ones. Many pads have a wear indicator tab that goes in a specific position — the photograph from earlier settles it.
Apply a thin film of brake grease to the back of the pads and to the slide pins, and to nothing else. Grease on the friction surface or the rotor ruins both.
Refit the caliper and torque properly
Slide the caliper over the new pads and start both bolts by hand. Torque them to the manufacturer's figure — this is a fastener holding your brakes to the car and it has a specification for a reason.
Refit the wheel, lower the car, then torque the wheel nuts in a star pattern with the wheel on the ground. Over-tightening is the more common error and it distorts rotors.
Pump the pedal before you move, then bed them in
Pump the brake pedal until it feels firm before the car moves at all. The piston is retracted and the first press or two only takes up that slack — driving off without doing this means no brakes on the first application. This is the step that causes accidents on driveways.
Then bed the pads in: a series of moderate stops from around 35 mph without coming to a complete halt, then drive gently for a few miles without holding the brakes at a standstill. This transfers an even layer of friction material onto the rotor and prevents the judder people later call warping.
Safety: Brakes are a safety system. Pump the pedal until firm before the car moves. If you are not confident compressing a piston or torquing fasteners to specification, pay a professional — and never let a caliper hang from its flexible brake hose.
Common Mistakes
Driving off without pumping the pedal
The retracted piston means the first pedal press does nothing but take up slack. People reverse off a driveway, press the brake, and find it goes to the floor. Pump until firm before the car moves an inch.
Letting the caliper hang on the hose
The flexible hose carries hydraulic pressure and is not designed to carry weight. Stretching it damages the inner lining invisibly, and a hose that fails later fails completely. Hang the caliper from the spring.
Ignoring seized slide pins
If a pin is stuck, the caliper cannot centre itself and one pad does most of the work. New pads on seized pins wear unevenly within months. Clean and grease them while the caliper is off — it takes ten minutes.
Skipping the bedding-in procedure
Bedding transfers an even layer of pad material to the rotor. Without it you get uneven deposits, which produce a pulsing pedal that gets blamed on warped rotors. It costs one drive and prevents a common complaint.
Front pads are a genuinely achievable afternoon and the parts cost a fraction of a shop bill. Check whether your rears are electronic before ordering anything, hang the caliper properly, torque what has a specification, and pump the pedal before you move.
Frequently Asked Questions
How long does it take to change brake pads?
About two hours per axle for someone doing it carefully for the first time, and closer to an hour once familiar. Seized slide pins or corroded caliper bolts are what turn it into a longer job, so allow more time than you think on an older car.
Do you need to replace rotors when changing pads?
Not automatically. Measure the rotor against the minimum thickness stamped on it and check the surface for deep scoring or a pronounced lip. Smooth rotors above minimum spec take new pads fine. Grooved, cracked or thin ones should be replaced, because new pads will not bed properly against a damaged surface.
Why do you have to pump the brake pedal after changing pads?
Because the caliper piston was pushed back to fit the thicker new pads, so the first pedal presses only take up that slack. Until the pedal feels firm, the brakes are effectively not there. Pump before the car moves — this is the step that causes driveway accidents.
Can you change rear brake pads with an electronic parking brake?
Only with a tool that can retract the caliper motors. Winding them back mechanically damages the mechanism. A bidirectional scan tool that supports your vehicle can do it, which is one of the main reasons people buy one. Without that tool, the rear axle is a shop job.
What is bedding in brake pads?
A series of moderate stops from around 35 mph, without coming to a complete halt, that transfers an even layer of pad material onto the rotor face. Skipping it leaves uneven deposits, which cause a pulsing pedal that is usually misdiagnosed as warped rotors. It takes one short drive.

How We Write Guides
Every product named in the “what you need” section is one we have researched and written about separately, and each links to that guide so you can see the reasoning rather than taking a recommendation on trust. We publish no prices, because they change faster than we can update pages. Where a job carries genuine risk we say so plainly rather than burying it, and where a job is beyond a home mechanic we say that too. Last reviewed August 10, 2026.
A note on safety: Pump the brake pedal until firm before the car moves. If you are not confident with any part of this job, brakes are the right place to pay a professional.
