Ever had the mishap of a “stuck” caliper? If you have it’s probably something you haven’t forgotten. What happens is that when you apply the brakes the pistons in the caliper press the pad against the rotor and the car slows. All good, right?

But when you release the pedal the piston does not return to its seated position, allowing the pads to release the rotor. How much of a problem is that? When it happened to me a 550 hp engine could barely move the car down pit road. Not good.

Several things can cause this, just disuse, like in a car that has sat for a period of time. Or, more commonly the heat cycles that the brakes go thru eventually deteriorate the seals.

The answer, is of course to add caliper maintenance to your check sheet. Every 2 or 3 races, pull the pistons, check them over and replace the seals. Seals are cheap insurance and it could save a lot of heartache.
