ACDelco GM OE DRUMS

Brake Rotors & GM OE Rotors | ACDelco

ACDelco GM Original Equipment Brake Drums are cylinder-shaped bowls where the wheel cylinder presses the brake shoes outward against the inside of the drum. Drums are typically found on older vehicles and on the rear axles of trucks and some cars. These original-equipment brake drums are engineered to fit your specific GM vehicle and provide the same performance, durability and service life as your factory-original equipment.

Signs of Wear & Troubleshooting:

  • Low brake-pedal height.
  • Increased stopping distances.

  • Brake-pedal pulsation (not to be confused with normal ABS operation).

 

Did You Know?

When you step on your brake pedal, you command a stopping force 10 times as powerful as the force that puts the car in motion. The brakes system can exert as much as 1,000 pounds (450 kg) of hydraulic pressure on each of the four brakes.

What It Does:

The Brake System applies frictional force to the wheels to slow or stop the vehicle.

Good Maintenance Practices:

The following inspections and maintenance procedures can help prevent potential brake problems:

  • Check brake fluid level at every oil change. Replace fluid according to Owner's Manual recommendations.
  • Calipers and wheel cylinders should be checked every brake inspection and serviced or replaced as required.
  • Inspect the brake lines for rust, punctures or visible leaks (you may be able to do this, but consult a qualified technician if necessary).
  • Check the thickness of your brake pads.


The following should be conducted by a qualified technician:

  • Inspection of the brake hoses for brittleness or cracking.
  • Inspection of brake lining and pads for wear or contamination by brake fluid or grease.
  • Inspection of wheel bearings and grease seals.
  • Parking brake adjustments (as needed).
