What causes a brake calliper to stick?

...

If you’ve noticed your car pulling to one side while driving or a burning smell coming from your wheels, you may have a stuck brake calliper. A sticking calliper can cause uneven braking, reduced fuel efficiency, and premature wear on your brake pads and rotors. But what exactly causes this pesky problem? Let’s take a closer look.

Symptoms of a stuck brake caliper

Some telltale signs that you’re dealing with a stuck calliper include:

  • Car pulling to one side, especially when braking
  • Squealing, grinding, or dragging noise from the brakes
  • Burning smell from the wheels
  • The brake pedal feels spongy or unresponsive
  • Reduced gas mileage

If you notice any of these symptoms, getting your brakes checked out ASAP is important. Driving with a stuck calliper is not only annoying, but it can be dangerous too.

Common causes of caliper sticking

So what makes a brake caliper get stuck in the first place? Here are some of the most frequent culprits:

  • Corrosion: Over time, rust and corrosion can build up inside the calliper, causing the piston to seize up. This is especially common in areas with harsh winters and road salt.
  • Debris: Dirt, dust, and grime can work their way into the calliper and prevent it from sliding smoothly. This gunk can come from the road or even from worn-out brake pads.
  • Damaged slide pins: The calliper relies on slide pins to move in and out. If these pins get bent, broken, or stuck, the calliper won’t be able to release properly.
  • Leaking brake fluid: A leak in the brake line or calliper can allow air bubbles to enter the system, reducing hydraulic pressure and causing the calliper to stick.

Repairing a stuck brake caliper

If you suspect a stuck calliper, the first step is to have a mechanic inspect your brakes. They’ll likely perform a visual check, test drive the car, and measure the thickness of your brake pads. Depending on the cause and severity of the problem, the repair may involve:

  • Cleaning and lubricating the caliper slide pins
  • Replacing the calliper, pads and rotors
  • Bleeding and flushing the brake fluid
  • Fixing any leaks in the brake lines

For most stuck calliper repairs, you can expect to pay anywhere from $300 to $1000 in New Zealand, including parts and labour. However, the exact cost will depend on your specific vehicle and the extent of the damage.
