out more about ACDelco Professional DuraStop Rotors/Drums and how
they fit into the Brakes system with the product
facts below.
Brake Rotor:
FUNCTION:
A rotating disc that helps slow or stop the vehicle when the brake pads press against its surface (disc brakes).
SIGNS OF WEAR:
Brake pedal pulsation (not to be confused with normal ABS operation), squealing or grinding noise, low brake pedal height, vehicle pulls to the left or right when brakes are applied.
Brake Drum:
FUNCTION:
A drum attaches to the wheel that slows the rotation of the wheel when the brake shoes contact its surface
SIGNS OF WEAR:
Reduced braking force, low brake pedal height, increased stopping distances, squealing or scraping noises, 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.
SERVICE AND MAINTENANCE:
The following inspections and maintenance procedures can help prevent potential brake problems:
Inspection of then 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) New DuraStop rotors DO NOT need machining.
Used rotors can be machined provided minimum
thickness can be maintained: Before you machine rotors,
make
sure the lathe is clean, within specs and has sharp tool bits.
After completing the finish cut,
sand both sides of the rotor for one minute per side using a sanding
block and 130- to 150-grit sandpaper to obtain a non-directional
finish. After sanding,
wash the rotor with dish soap and water. DO NOT clean the rotor with
brake cleaner/solvent-based product. Thoroughly clean the calipers,
caliper slides
and hardware. Remove all dirt, rust and grease.
DuraStop brake tech tips:
Lubricate
caliper slides, shims and rubber components. Use ACDelco silicone-based lubricant or
equivalent before installation. ACDelco lubricant is rated at
2,000° F. DO NOT use a petroleum-based or spray adhesive
product: Lubricate all hardware rubber
components and all metal-to-metal contact points. Give caliper slides and disc
pad
shims/insulators a thin film of lubricant. This will allow the shim
to withstand normal brake pad movement without damage to the shim.
Additionally, this helps dampen vibration. Make sure the disc pads are tight in the
caliper and torque the caliper to the housing. Check the adjustment of the rear brakes.
Adjust if necessary. After cleaning all wheel-hub mating surfaces,
install the wheels. Make sure they are torqued to
manufacturer's specifications.

SERVICE AND MAINTENANCE:
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)
- The following should be conducted by a qualified technician:
