Brake Repair in St. Louis, MO

You step on the brakes and your car comes to a stop. It’s something we do thousands of times every year and we just take it for granted…up to the point where something goes wrong.

Your disc brakes aren’t unlike the hand brakes on a bicycle. The wheels are bolted to smooth steel rotors, called discs, and a heavy caliper encloses part of the rotor like a clamp. The caliper holds the brake pads, and when you step on the brake pedal hydraulic pressure forces the pads against the rotor, dragging the vehicle to a halt via friction.

Brake Repair in St. Louis, MOThe friction material of the brake pads is a ceramic or semi-metallic compound that may take as many as 60,000 miles to wear down. With wear that’s so gradual, it can be hard to know when it’s time for brake service. Here are some sure signs, though:
  • Strong pull to one side while braking
  • Vibration or pulsation through the brake pedal while braking
  • Longer stopping distances
  • Longer brake pedal travel before brakes engage
  • One or more wheels tends to lock up and skid while braking
  • Brake pedal feels “soft” or “spongy” underfoot
  • Brake pedal slowly goes to floor while holding the vehicle stopped and in gear
  • Loud squeal, groan or metallic grinding noise while braking

Of all these, the grinding noise is by far the worst. It means that your brake pads’ friction material has worn to a point where the metal backing plates of the pads are exposed. All your braking effectiveness is coming from metal/metal contact, and the metal plates are quickly digging grooves into your rotors. Very dangerous!
