Are rusted brake calipers bad?
Yes, they are, so don’t disregard extensive rust in your calipers. While minor surface rust is not a problem, excessive rust on your caliper’s slides, bushings, and pins may prevent a “floating” caliper from centering itself over the rotors. Because of this, your pads may wear out unevenly and cause unreliable braking.
When do you need to replace a caliper?
Caliper replacement is required if a caliper is leaking brake fluid, if a piston is sticking, or the caliper is worn or damaged. Leaks are very dangerous and should never be ignored because loss of fluid can cause brake failure.

On modern vehicles, it's not uncommon for calipers to last at least 100,000 miles or 10 years. Because caliper life can vary significantly depending on how you drive, the climate you live in, and the humidity level in the air, automakers have always avoided making replacement recommendations at specific intervals.
Should I replace both calipers or just one?
For vehicles with disc brakes mounted on only the front wheels and tires, replace the calipers in pairs. If one side is damaged, then replace the calipers on both sides. If only one caliper is replaced, you may experience brake imbalance between the front wheels and tires.
How often should calipers be replaced?
Most brake calipers do not need to be rebuilt or replaced the first time the brakes are relined. But after 75,000 miles, or seven to 10 years of service, the calipers may be reaching the end of the road. As the rubber seals age and harden, the risk of sticking and leaking goes up.
What causes calipers to go bad?
A leading cause for damaged calipers, however, stems from driving a vehicle on worn-out pads or warped rotors. Both prevent the system from dissipating the heat of friction, as they're designed to do, which can damage the calipers.
Why did my calipers rust?
Rusty brake calipers are a byproduct of time, plain and simple. Endless cycles of rain, sun, dry and wet conditions, cold and hot weather are guaranteed to leave a mark.

Why do rotors rust?
Rust is a fact of life for rotors because the best metal for them is highly susceptible to corrosion. It is an issue for car manufacturers - the cars sit on the lot for months waiting to be sold and the rotor rusts slightly everywhere but where the brake pad seals moisture out.
Can cast iron rotors rust?
As you probably well know, bare iron or steel will rust very easily. The cast iron of this rotor is no exception. The apparent smoothness of the side of your rotor we can see leads me to believe you have plenty of pad left at least on this side (the inside may be a different story).
Do brakes get hot?
For the rust which is present, it is easily explained. When brakes are used they get very hot. Except for a few exterior coatings which prevent this, most coatings/paint heat up and peel off, leaving a nice fresh surface of bare metal behind (even more so if there's no coating in the first place).
When should brake calipers be inspected?
Whenever any brake work is being performed on your car, whether that's pads, rotors, or a fluid flush, the calipers should be thoroughly inspected for any possible needs. This is the most opportune time to check for corrosion, leaks, or any signs of damage.
What is brake caliper?
Brake calipers, found only on disc brake systems, house pistons which use the force of hydraulic brake fluid to stop the vehicle. More specifically, those pistons squeeze brake pads against rotating disc brake rotors - creating the friction necessary for scrubbing off speed.
How do floating calipers work?
As we mentioned before, "floating" calipers slide on guide pins from side to side over the brake rotor. As caliper pistons move outward, the inboard pad contacts the rotor first, causing the caliper to slide over until the outer pad makes contact with the rotor.
Why do brake pads wear unevenly?
As a result, brake pads will wear unevenly if proper contact isn't made when a caliper hangs up. Excessive wear on outer brake pads may result if brakes stick instead of releasing freely, since that side won't be pulled away from contact with the rotor.
Why is it dangerous to have brake fluid leaks?
Of course, ANY brake fluid leakage is very dangerous, because if enough fluid leaks out, the vehicle may completely lose its hydraulic brake system.
Where does the floating caliper center?
When the brakes are released, the floating caliper self-centers itself over the middle of the rotor. Your vehicle owner manual may tell you whether your disc brake calipers are fixed or floating - but if not, a quick call to the manufacturer's headquarters should provide an answer.
How long do disc brakes last?
On modern vehicles, it's not uncommon for calipers to last at least 100,000 miles or 10 years.
What to use when replacing a caliper?
If you’re replacing a caliper, use new slides, bushings and mounting hardware, and be sure to grease these parts with a high-temperature, moisture-resistant brake lubricant. If the slides or bushings on a floating caliper are rusty, worn or damaged, the caliper may not move freely causing the pads to wear unevenly.
Why do shops rebuild their own calipers?
Few shops rebuild their own calipers these days because it takes too long and increases the risk of a comeback if the caliper sticks or leaks. It’s easier, faster and safer to simply replace the old calipers with new or remanufactured calipers.
How long do brake calipers last?
Most brake calipers do not need to be rebuilt or replaced the first time the brakes are relined. But after 75,000 miles, or seven to 10 years of service, the calipers may be reaching the end of the road. As the rubber seals age and harden, the risk of sticking and leaking goes up.
Why are loaded calipers better than calipers?
Loaded calipers are even better because they give you everything you need in one box, and there’s much less chance of mismatched parts. Caliper replacement is required if a caliper is leaking brake fluid, if a piston is sticking, or the caliper is worn or damaged.
Why do calipers freeze up?
But both fixed and floating calipers alike can sometimes “freeze up” or lock if a piston becomes jammed or stuck in its bore due to corrosion or swelling.
What does uneven wear mean on brake pads?
If you find uneven pad wear between the inner and outer disc brake pads, it’s a sure indication the caliper (or caliper piston) is sticking. Calipers should usually be replaced in pairs, especially on high-mileage vehicles.
Can a caliper cause uneven brakes?
Mismatches side-to-side may cause uneven braking. Other items that may be needed when replacing calipers include new brake hoses (replace if leaking, cracked, brittle or worn), and certainly brake fluid. Always flush the brakes to get rid of the old fluid, and bleed all of the lines to get rid of any trapped air that could cause a soft pedal.
What to do if caliper fails?
If your caliper fails any of these visual inspections, it’s a good idea to replace the caliper. Keep in mind, many calipers do not come with the replacement hanger, so if your hanger does have signs of failure issues, you will need a semi-loaded caliper, or replacement hanger. 5.
What are guide pins on a brake caliper?
In most calipers, these guide pins secure the caliper to the caliper hanger, and need to glide in and out effortlessly. The pins need to be cleaned thoroughly and properly lubed with brake grease before reassembly. Failed guide pins will usually become seized or extremely difficult to remove.
How to tell if brake pads are worn thin?
When one caliper works and another doesn’t, your vehicle will jerk to one side as you attempt to slow down or come to a complete stop. Squealing, grinding, and metallic scraping noises while braking are all signs that your brake pads are probably worn thin.
What happens if one wheel has more resistance to turn than the other?
If one wheel encounters more resistance to turn than the other, this side’s brake caliper may be suspect. Keep in mind, some calipers can intermittently stick or hang-up, and if that’s the case, if it’s not hanging up at this time, both wheels will not encounter different resistance. 3.
Why do brake pads get hot?
At the same time, a stuck caliper that is applying constant pressure to a brake pad or pads will cause that side of the car’s braking system to get extremely hot.
How does a brake system affect braking?

Clean each piece individually and make sure that there’s nothing left on there that would interfere with laying down the primer coating. Once you’re sure your caliper is all nice and clean, plug off every hole using tape or whatever you got at hand. Honestly, earplugs w…
Step 6 – Painting The Calipers
- With the calipers ready for painting, you can start spraying the primer. Use three coats of primer with plenty of time for each coat to dry off. Now comes the part where you chose the color you want your calipers to be in. Some people like a solid black coat of paint while others have a thing for a flashy, borderline neon shade of green. It’s your call; we won’t judge. Applying three coats o…
Step 7 – Reassembly and Installation
- All you’re left to do now is put the caliper back together, making sure that all of the parts fit nicely. Applying a bit of brake fluid around the piston and on the seals should make the whole process go smoothly as well. Slap a pair of new Brembo pads, and you’ve got yourself a wholly rebuilt brake caliper that looks awesome and performs excellently. Just make sure to use new brake fluid per …
