Is the caliper supposed to move?
Most cars are fitted with a floating brake caliper system. It is by nature free to move laterally by about an inch or so and seeing this could understandably alarm those unfamiliar with the system. Floating caliper movement is normal behavior. You can easily check if the caliper is secure.
Why would my caliper be loose?
Worn rotors/pads do not commonly make calipers loose, however they can severely damage the aforementioned elements, specially the caliper ears in those with sliding pins… too much rattling can make things loose, damage holes, etc.
How are brake calipers supposed to move in a car?
As the caliper has the ability to slide laterally across the rotor, it only needs to employ a single piston. On initial application of the brakes, brake fluid forces the single inner piston outward and the inner brake pad meets the inside of the rotor.
How does the stopping power of a caliper work?
The stopping power of a caliper is determined by its clamping force — the amount of force it can apply to the surface of a rotor. This is primarily a function of the number of pistons and the surface area of the brake pad (where it actually contacts the rotor).
What’s the difference between fixed and floating brake calipers?
Fixed calipers are fixed firmly to the brake carrier and the more common floating caliper is free to move laterally on it’s sliding pins. In this post you’ll learn how to check that your brakes are indeed tight.
How do you remove the caliper from a car?
If you can’t remove the caliper by hand, then place the end of a flathead screwdriver between the brake rotor and caliper. Pull the screwdriver handle up to lift pry the caliper off of the brake pads. Once you remove the caliper, you’ll see the brake pads held in place by the caliper bracket.
