The Short Answer
To paint brake calipers without removing them, lift the car safely onto axle stands and take the wheels off, clean the calipers with a wire brush and brake cleaner, then mask everything around them. Apply several thin coats of heat-resistant caliper paint, 10 to 15 minutes apart, and leave it at least 24 hours before refitting the wheels.
Freshly painted calipers behind a set of clean alloys make a car look sharper for very little money, and it's a job you can do on your drive in a weekend. Most of the time goes on preparation, and that's where a good finish is won or lost.
Brakes get extremely hot under hard use and live in a cloud of brake dust, so ordinary paint won't last. You'll need a heat-resistant brake caliper paint that's made for the job.
Tools And Materials You'll Need
- A wheel brace or socket to undo the wheel nuts
- A trolley jack and a pair of axle stands
- A wire brush and a can of brake cleaner
- Masking tape, plus newspaper or plastic bags to cover everything else
- Your chosen caliper paint
- A torque wrench for refitting the wheels
Work in a garage or under cover if you can. A shower halfway through the second coat will ruin your afternoon.
How To Paint Brake Calipers Without Removing Them
- Lift the car and take the wheels off. Loosen the nuts while the wheel is on the ground, jack the car up at the correct point and support it on axle stands before you remove the wheel. Do the fronts only or all four, whichever you prefer. If you haven't lifted a car before, read our guide on how to use a car jack safely first.
- Clean the calipers thoroughly. Scrub off loose rust and dirt with a wire brush, then soak the caliper in brake cleaner and let it dry. Paint won't stick to grime, and any dust left behind shows through the finish.
- Mask everything that isn't caliper. Remove the retainer clip, cover the bleed nipple with tape and wrap the disc, hub, suspension and arch until only the caliper body is showing. Cover more than you think you need, because overspray on the disc or hub is a pain to get off.
- Apply several thin coats. Build the colour up gradually and leave 10 to 15 minutes between coats. One thick coat runs down the caliper and leaves a messy finish that's hard to rescue.
- Let it dry fully. Plenty of brands say their paint is dry within a few hours, but we leave it at least 24 hours. Paint that hasn't cured properly loses its heat resistance and can distort the first time you brake hard.
- Refit the wheels and lower the car. Take care not to knock the fresh paint, then tighten the wheel nuts to the manufacturer's figure with the torque wrench once the car is back on the ground.
The photo shows how far the masking needs to go. Only the red caliper body is left open, with the hub, disc and arch wrapped in newspaper and a bag so nothing else catches the paint.
Painting Brake Calipers With Them Off The Car
If you're confident taking a caliper off, painting it on the bench saves all the masking and lets you work at a comfortable height. You'll get into the corners more easily, and it's easier to get an even finish.
The trade-off is that you're disturbing the braking system. Unbolting the caliper from its carrier without opening the hydraulics is the simpler option, but if you disconnect the brake hose you'll need to bleed the system afterwards, and our guide to brake fluid explains why that matters. Anyone unsure about working on brakes should paint them in place.
What Colour Should You Paint Your Calipers?
Pick a colour that works with the bodywork and the wheels rather than fighting them. Red, yellow, green and silver are the classic choices, and blue sits well on plenty of electric cars.
Bright colours show up best behind open spoke wheels, while a darker car with busy alloys suits something subtler like silver or graphite. Give the wheels a proper clean afterwards, as our guide to cleaning alloy wheels shows, so the new paint isn't hidden behind brake dust.
Take Your Time With The Prep
Most people paint their calipers in place, and that's how we'd do it on a car that's used every day. Spend the time on cleaning and masking, keep the coats thin and give the paint a full day before you drive, and the finish will hold up to proper use.
Brake Caliper Painting Questions We Get Asked
Can You Paint Brake Calipers Without Removing Them?
Yes, and it's how most people do it. With the car safely on axle stands and the wheel off, you clean the caliper, mask the disc, hub, suspension and arch, then spray or brush on thin coats. It takes longer to prepare than painting a caliper on the bench, but you never touch the hydraulics, so there's no brake bleeding afterwards.
How Long Does Caliper Paint Take To Dry?
Leave 10 to 15 minutes between thin coats, then let the paint dry for at least 24 hours before refitting the wheels and driving. Some brands say their paint is dry within a few hours, but paint that hasn't fully cured loses its heat resistance and can distort under hard braking, so the extra wait is worth it.
Do You Need Special Paint For Brake Calipers?
Yes. Calipers get extremely hot under heavy braking and are constantly coated in brake dust, so standard spray paint discolours and flakes. Use a paint sold specifically for brake calipers, which is formulated to handle the heat and resist brake dust and cleaning chemicals. Our roundup of caliper paints covers the ones we rate.
How Many Coats Of Caliper Paint Do You Need?
Plan on several thin coats rather than one or two heavy ones. Thin layers build an even colour and don't run down the caliper body, which is what spoils most DIY jobs. Stop once the colour is solid and even with no metal showing through, then leave the final coat to dry fully before the wheels go back on.
Should You Sand Calipers Before Painting?
A wire brush is enough for most calipers, used to knock off loose rust and flaking old paint before a thorough soak in brake cleaner. The aim is a clean, dry and dust-free surface the paint can grip. If the existing finish is peeling badly, take it back further, because new paint won't hold on to coating that's already lifting.
How Do You Keep Paint Off The Brake Discs?
Mask them completely before you start. Wrap the disc, hub and surrounding suspension with newspaper or plastic bags held by masking tape, and tape over the bleed nipple, leaving only the caliper body exposed. Paint on the disc surface affects braking, so if any gets through, clean it off with brake cleaner before you drive.
