It’s about timethis retirement rumor stops. The truth is...

Brake Repair Means BusinessBrake repair is among the leading drivers for automotive repair facilities because of the replacement rate. A key to increasing brake business is the ability for service writers to get what they need when they need it — if you don’t have them in stock, you can’t sell them or install them. Listed below are the top ten drum system part numbers including hardware:

Avoid Premature Retirement of Drum SystemsUnder normal conditions — and when adjusted properly — rear brake shoes will last two to three times longer than the front pads. This is because the proportioning valve limits the amount of pressure to the rear brakes.

Extending the Life. The drum brake system should be inspected during every brake job, even if only the front brakes are being serviced. The rear brake shoes and emergency brake should be checked and adjusted. All the hardware should be checked for broken springs or pieces. If there are any signs of leakage near the rubber boots of the wheel cylinders, the wheel cylinders should be replaced. If no leakage is obvious, the rubber boots should be peeled back to make sure no fluid runs out.

Positioning. A problem that accelerates wear on the rear brake shoes is when they are installed in the wrong position. It is imperative that the low shoe with the most bare metal backing on top is located in the front toward the engine. The high shoe is located in the rear. They will fit either way, although the wear rate will be dramatically different.

Shoe and Drum Wear. Brake shoes should be checked for cracks, missing pieces and for wheel cylinder contamination. Shoes should be replaced when the braking material is only 1/8-inch thick at any point. The brake lining should be inspected for deep grooves that could reduce brake effectiveness. If this is indicated, the drum will also be grooved and must be machined to eliminate this condition. Drum warpage can be checked by turning the rear axle with the drum on the brakes and see if it hangs up or can be heard rubbing in any location. Drum diameter should be checked prior to turning. If the inside diameter of the drum exceeds the diameter limit spec stamped or cast on the outside of the drum, it should be replaced.

Parking Brakes. Parking brakes and cables should be examined during every brake job for damage, corrosion, proper adjustment and operating condition. Customers should be advised to engage them regularly to prevent corrosion and ensure normal hydraulic operation.

34 Stability Control

New Technology. Drum Brake Systems Now Support ABS and Stability Control Programs – These technologies once drove designers and engineers away from using drum brake systems. Now, technological advances allow drum brake systems to work seamlessly with these advanced safety features.

Costs Less. Lower Cost to Vehicle Manufacturers than Disc Brakes – The caliper assemblies required in disc brake systems are more expensive, making drum brakes a more cost-effective choice. A four-wheel disc brake system requires an additional assembly for a parking brake, while a drum brake system can double as a parking brake system.

Weighs Less. Drum Brake Systems Weigh Less Than Disc Brake Systems – Gas mileage standards are a driving force in many of today’s vehicle designs. The lighter weight of a drum brake system is a desirable solution to removing overall weight from a car or truck.

Higher Braking Standards. Drum Brake Systems Meet Federal Safety Standards – In recent years and as Federal Motor Vehicle Safety Standards (FMVSS) have changed, some OE designs have found that using drum brake systems allow them to meet new, higher braking standards.
