What is a brake caliper replacement?
When you take your car in for a brake caliper replacement service, the mechanic will assess the calipers to confirm if any replacements are needed. The mechanic will also check the brake pads, as they will likely need a replacement.
The brakes need the brake calipers to function, as they push the brake pads onto the rotors to slow down or stop your car.
A car can have two or four calipers. A car with two rotors and two drums will have two calipers in the front. If a car has four rotors, it will have four calipers. When the calipers become contaminated and rusty, they can leak brake fluid.
If a brake caliper is leaking, insufficient brake fluid will reach the pistons in the caliper to push the brake pads onto the rotors. The brakes will not be able to function at full capacity.
How do I know if my brake calipers need replacing?
If you see any physical damage or leakage, it might be time to replace your brake calipers. Other common symptoms to look out for that may indicate a damaged or failed brake caliper include:
Physical damage, including rust and weakened seals
Abnormal squeaking noises
Car pulling hard left or right when braking
Brake pedals feel soft and spongy
A leaking or worn-down caliper is a big risk to you and the cars around you, as the brakes won’t function at their full capacity. This increases the risk of a collision because your vehicle won’t stop as quickly if the car in front of you suddenly brakes.
Pro tip: Have your brake calipers inspected every time your car is serviced. This allows the mechanic to monitor for any issues before any leakages occur.
How often should brake calipers be replaced?
Brake calipers aren’t generally considered maintenance items—they’re not expected to wear over time and are usually only replaced if they fail, are damaged, or you want to upgrade them. This is why experts normally set the lifespan for brake calipers between 75,000 to 100,000 miles or every 10 years.
Some drivers may be able to go longer before replacing their calipers, but it’s a good idea to have your brake system routinely inspected to ensure it stays in proper working order.
Generally speaking, brake pads and rotors wear out faster and need replacing more frequently than brake calipers. However, one of the most common causes of worn-out calipers is driving on worn-out pads or warped rotors. Worn pads or rotors inhibit the brake system from dissipating the heat of friction, damaging the calipers.
Regular brake system inspections and maintenance will not only ensure your car’s safety, but it can also help extend your brake calipers’ lifespan.
Can I replace my brake calipers myself?
If you’re a car-savvy DIY-er and know your way around with a wrench, replacing your brake calipers is usually simple. For most people, the post-replacement brake bleed is the toughest part. But if you have any hesitation about tackling the job, let a professional change your calipers.
