BRAKE CALIPERS 101

Brake calipers are the 'hands' of your brake system. Just like grasping a frisbee, the brake calipers act as the 'hands' and your brake pads are the 'fingers'. When you apply the brakes, brake fluid pressure builds up behind the caliper piston. This gain in pressure forces the piston outward. As the piston moves outward, it presses the brake pads together.

TYPES OF BRAKE CALIPERS 

  • Sliding: Sliding calipers use guide pins as the mechanism to engage and disengage the brake pads. There are 2 guide pins per brake caliper. The guide pins are housed in the brake caliper bracket. The brake caliper slides on these pins. Sliding brake calipers typically have 1 or 2 brake pistons.

  • Fixed: Fixed calipers are typically seen on Toyota trucks, some newer GMC's and European vehicles. The brake caliper and the caliper bracket are all 1 piece. Fixed calipers typically have 4 pistons, 2 on each side of the rotor. The guide pins on fixed calipers are a little different. The brake pads have two guide holes on the top of the pad. The guide pins slide through these holes and the brake pads essentially 'hang' off of these pins. All of the other basic caliper functions are the same.

SIGNS OF WORN BRAKE CALIPERS

  • Dragging Brakes: If you're noticing brake drag or sticking brakes, calipers are the most likely culprit. The guide pins and/or brake caliper piston may be stuck or seized. When either get stuck, it causes the brakes to drag or not disengage.

  • Leaks Present: If brake fluid is present around the brake caliper piston, the caliper will need to be replaced. The brake caliper piston uses a square cut o ring which prevents the fluid from leaking out of the caliper.

Frequently Asked Questions

DO YOU COME TO ME?

Yes. We're a completely mobile brake repair company. We do not have a physical shop location.

HOW LONG DOES IT TAKE TO FIX MY BRAKES?

Most brake services take 1 to 2 hours to complete.

WHY ARE MY BRAKES GRINDING?

When you're experiencing brake grind, it means you waited too long to replace the brake pads. Once the brake pads wear out past he point of no return, the metal backing will start to contact the rotors. This metal on metal friction creates the grinding noise and destroys the rotors.

WHICH BRAKE ROTORS DO I NEED?

In this Houston weather, we highly recommend using fully or partial coated brake rotors. Coated rotors help prevent rust & corrosion from prematurely eating away the rotor.
