2006 Chevrolet Cobalt Brake Drum Parts Questions & Experts Answers

• Q: What tools are required to refinish brake drums and what steps should be followed on 2006 Chevrolet Cobalt?

  A: Refinishing brake drums needs two separate kits: Rotor/Drum Flange Resurfacing Kit J 41013 and Hub Cleaning Kit J 42450-A. Refinish brakes only when you see severe surface corrosion, deep damage, deep cracks, extreme overheating marks, darkened spots, or unwanted drum surface roughness along with unacceptable level of radial runout. First take off tires and wheels to measure brake drum diameter and spot brake surface wear or diameter unevenness. To resurface the brake drum flange apply the Rotor/Drum Flange Resurfacing Kit (J 41013) and follow the brake lathe manufacturer instructions with vibration dampening attachments safely secured. Place the cutting tool against the rotating drum while monitoring the tool's marking edge for correct mounting. The manufacturer guides lead operating procedure when refinishing the drum with checks for diameter changes and replacement if the finished drum exceeds manufacturer limits. Use 120 grit aluminum oxide sandpaper on the finishing tool when it lacks a directional mechanism or 150 grit when using a sanding block. Wipe all particles from your brake surfaces using denatured alcohol or a brake cleaner replacement. Take off the drum from the lathe and use the kit (J 42450-A) to clean away wheel bearing corrosion. The cleaning keeps the brake system from making a pulsing sound.
