While many other components on a vehicle can cause this to happen, inspection of the brake calipers is important to rule out the possibility of a brake caliper issue. Additionally, when an auto repair shop is servicing the brake system on a vehicle, a technician has to retract the pistons in order to install new brake pads; brake calipers are also inspected for leaks at this time.
Depending on which style you choose to purchase, it will have an impact on the price. It is important to note that both styles may or may not be available for certain vehicles, although generally speaking both options exist for most vehicles. Additionally, both fixed and floating brake calipers can come either Friction Ready, or Loaded.
The replacement time for brake calipers on 1 axle is between 2 and 3 labor hours, but can be more on some applications. A friction ready brake caliper will generally be the less expensive option since it does not include a set of brake pads. Since there is such a wide variety of brake systems in use on vehicles today, there is also a large range in the replacement cost of modern day brake calipers. With the wide variety of replacement options, comparison of multiple brake caliper offerings generally allows comparison shopping of this component on most applications.
After replacing a brake caliper on a vehicle, the brake system must be bled of air. Brake calipers are also sometimes replaced when an issue is discovered during a routine brake job. Lastly, rubber brake hoses may also be suggested for replacement based on their condition when a brake caliper is replaced. It has gone bad. Of course, if you ignore the signs of a rotten egg, your nose will figure it out as soon as you crack it open.
The same can be said of your brake calipers. When your brakes are wearing out, they will send you signs. Just as with a rotten egg, if you ignore the signs of a bad brake caliper, they will become far less subtle. The symptoms will escalate and the problem will become more evident. Damage will likely be the result. What is a brake caliper?
That system relies on hydraulic pressure to operate. When you press on the brake pedal, force is exerted through fluid inside a network of hoses and tubes to the wheels. Attached to each wheel is a heavy metal disc called a brake rotor. As your wheels roll down the road, the rotors spin with them. Sandwiched around each rotor is a pair of brake pads.
Those pads are suspended in a hydraulic clamping mechanism - the caliper. Every time you step on the brakes, the calipers squeeze the brake pads against the rotors in the same way someone in a wheelchair might grab the wheels to slow down. A bicycle works in a similar fashion. When you grab the brake lever, a cable actuates a caliper to squeeze a pair of rubber brake pads against the sides of your bike wheel. In each case, friction is created and the kinetic energy of a body-in-motion is converted to thermal energy to slow you down and bring you to a stop.
What are the signs that a caliper has gone bad? Fortunately, your brake calipers are designed to last. Where your brake pads are designed to wear out with use your rotors too, to some degree , a caliper is not considered a wear item, one that needs regular replacement. That said, they do sometimes fail. How can you tell?
A bad caliper might present itself in the following ways. During an inspection. The best way to detect a faulty brake caliper is to have your brake system inspected regularly. A technician can spot the early warning signs of a failing caliper - corrosion, dirt buildup, leak, reluctant guide pins, and more - before they become a major issue.
If a caliper already has problems, the technician might notice uneven brake pad wear resulting from a caliper that is either stuck open or stuck closed. The cost of replacing them may not be a bad number to keep in the back of your mind. That depends; there are a couple of variables at work here. The first variable is, what exactly is wrong with the caliper? Is it leaking or did it simply freeze up?
Either way it will need replaced, and in all likelihood so will your brake pads.
