The Danger of Squealing Brakes
Abnormal wear and checking the caliper’s piston are two ways to check a brake caliper. When you push the brake pedal to apply the brakes, brake fluid is released into a caliper. There are fixed and floating calipers. Fixed calipers mount to a steering knuckle, and floating calipers mount to an adapter plate bolted to a steering knuckle.
The pressure forces a piston inside a caliper to squeeze the brake pads against the rotor. Friction is created by this chain of events, and the vehicle decelerates and stops. A caliper mounts to a steering knuckle. Brake hoses deliver pressurized fluid to the caliper. Bleeder screws are used to empty air from the brake system. There may be one or two pistons to bleed.
Do you notice your vehicle pulling to one side when driving? Many people think it’s an alignment issue which it could be. Still, there could be an underlying condition and serious braking issue with a failing brake caliper.
As you continue to drive, do you notice a dragging sensation? Brake calipers sometimes get stuck and cause the brake pads to be pressed against the rotor while driving. The brakes are partially engaged when driving, even when your foot is not on the brake. That is dragging.
Pulling to one side and a squealing sound are signs of a seized brake caliper. A failing brake caliper will emit a similar sound worn-out brake pads make. It’s a rubbing sound that may escalate to metallic grinding, scraping, or rubbing. Many drivers don’t understand the various noises associated with brake caliper failure and assume it’s an alignment issue that can be overlooked or delayed until later. Stop playing mechanic and go visit Cottman Transmissions.
This thinking can lead to frustration when operating your vehicle. A bizarre sound was noticed, and you ignored the issue based on faltered logic. Your friends will most likely say it’s your alignment. You need to take immediate action and contact Cottman Transmission in Cincinnati, OH.

To test the caliper, you must put the car on a lift or jack stand. If the wheel is hard to turn, a caliper may stick and push the pads against the rotor. A second method to test the caliper piston is to try to push it back into its bore.
A leak from a brake caliper can result from a leaky piston or bleeder screw. The hydraulic fluid seeps out, reducing braking ability, which could result in serious damage to your vehicle or another motorist.
