Can you drive with a broken caliper seal?

You notice a fluid leak. Sometimes a brake caliper will leak. This is not normal; in fact, it can be dangerous if your brake system loses hydraulic pressure because of a leak. Do not drive your car if it is leaking brake fluid from the calipers or anywhere else. Have it towed to a repair shop for brake service.

On modern vehicles, it’s not uncommon for calipers to last at least 100,000 miles or 10 years. Because caliper life can vary significantly depending on how you drive, the climate you live in, and the humidity level in the air, automakers have always avoided making replacement recommendations at specific intervals.

What causes a leaky brake caliper?

Failed Piston Seal Brake components like the master cylinder, disc brake caliper, or drum brake wheel cylinder all function through a piston. The piston is a moving part that’s activated by brake fluid. It has seals that help contain the fluid, and these can be damaged from regular wear and tear, causing a leak.

What do you check a caliper seal for?

To determine if a caliper piston is operating correctly, you must ensure that the square cut seal is working. The square cut seal is what allows the caliper piston to retract back into its housing. Just because you can manually push the piston in, doesn’t mean the square cut seal is working.
