Every time you hit the brakes, whether you're coming to a routine stop or screeching to a halt just inches from the bumper in front of you, thank the Acura brake caliper for doing its job. Each Acura brake caliper-there are four on your car, one at each corner-contains a piston or pistons in a bore, along with a pair of brake pads. When you hit the brake pedal, fluid is pushed up against the pistons in your Acura brake caliper, and the pistons push the brake pads, sandwiching the brake rotor between them. The force of your stationary Acura brake caliper squeezing the spinning brake rotor is what brings your Integra or TL to a stop. Now, you don't have to be a rocket scientist to figure out that there's a lot of heat generated when your Acura brake caliper is doing its job. That's why the Acura brake caliper is generally made of steel or iron, to help it absorb some of that heat and prevent the brake fluid from boiling. Additionally, the Acura brake caliper has to be extremely strong to withstand the incredible forces generated as it tries to drag two tons of car to a halt. So make sure you take care of each Acura brake caliper on your vehicle. Be on the lookout for fluid leakage; if the seals in your Acura brake caliper go bad, they allow brake fluid to escape from the Acura brake caliper housing, resulting in poor pedal feel, pad contamination, and other dangerous conditions. Likewise, don't let your pads wear too low, since this can cause Acura brake caliper damage. Take care of each Acura brake caliper and they'll do their best to make sure you stop in time to avoid serious trouble.
