Can you drive with a sticking caliper?

Sticking calipers impair performance as much asefficiency. In the vast majority of cases, only one caliperwill be affected — even if more than one issticking, the severity of the problem will probablydiffer. Since one wheel is affected more than the others,your vehicle will pull to the right or left as youdrive.

Clean the area on the piston and caliper where the padbacking plate touches. Apply the anti-squeal adhesive,reinstall the pads and button up. These anaerobic products willstay gummy until you apply the brakes and squeeze out theoxygen. Then they stick like, well, glue.

What causes brake drag?

Brake drag is caused by the brakepads or shoes not releasing completely when the brake pedalis released. A worn or corroded master cylinder bore causesexcess pedal effort resulting in dragging brakes.Brake Lines and Hoses: There may be pressure trapped in thebrake line or hose after the pedal has beenreleased.

How often should you change drum brakes?

The braking habits of the driver as well as thequality of the original brakes are far more indicative ofwhen brakes should be replaced than the mileage on thevehicle's odometer. That said, for a Honda Civic, the generalconsensus seems to be around 60,000 to 90,000 miles or the life ofthree brake pads/drums.
