Car brake drum rear and front

Brake drum is a part of brake system that plays an important role in braking. Braking effect is achieved by converting kinetic energy into heat that is absorbed by the brake drum. This is a simple mechanical process. But there are special material strength requirements, which the brake drum is made of, as it is subjected to strong mechanical stresses. In brake drum friction pads are located inside the drum, while in the brake shoes or clamping bands friction surfaces are outside.

Excessive heating that occurs during braking, requires the use of special alloys with a high wear resistance. However, wear occurs. So each time you change tyres, inspect the brake drum for obvious signs of wear. It can be deformed, for example. If you find defects or signs of corrosion on the surface of the drum, screening is necessary. Manufacturers specify the maximum diameter of the brake drum. These values should be guided when estimating wear. In addition, brake drum can be damaged in the result of an accident.

Worn brake drum or drum with a clear defect should be replaced immediately, because the risk of brake failure is too great. Brake drum replacement should be done in the auto repair shop. Brake system repair is related to car safety and even the slightest error can have serious consequences. So do not do this by yourself and trust professionals. In our online shop you will find rear view mirrors, mufflers, spoilers and fenders. You will be able to install them without any assistance if you have mechanical skills. Our Internet shop guarantees the best quality and reasonable prices.

Drum brakes failure

• part surface deformation;
• increase of the gap between shoes and drums;
• drum entire surface worn-up;
• part deformation;
• wear out;
• oiling of the part working surface;
• cracks or indents occurrence.

Signs of brake drum failure

• worsening of vehicle response;
• lengthening of brake path;
• vibration or extraneous sounds when braking;
• beating vibration of the steering wheel or brake pedal;
• skids when braking;
• excessive free travel of the brake pedal.

Causes of brake drum failure

• untimely components replacement;
• sporting driving style;
• damages or worn-out drum return spring;
• usage of low-quality consumables;
• frequent driving on the roads with low-quality surface;
• installation of unsuitable parts or faulty components;
• thermal impact.

Diagnostics

The experts will perform diagnostics of the entire braking system at the service station. It is examined at the special repair bench where the resistance of each of the wheels when braking will be estimated. We remind that the maximum indicator of the drum diameter shouldn’t exceed 204,4 mm. Higher rate testifies that the component should be replaced. We will note that you will be able to diagnose the system yourself. So, accelerate the car to 70 kilometers per hour, be sure the road surface is flat and dry. Then press the brake pedal sharply. If the car starts skidding or if you feel the pedal or steering wheel vibrations, hear extraneous sounds, you need to inspect the braking system at the service station urgently. Inspect the system in such way every 20000 operational kilometers, and do the cleaning and preventive maintenance of the unit every 10000 operational kilometers.

Drum brakes repair

Perform the machining of the drum in order to remove surface shears that increase braking path and make the car vibrating. Also it should be taken into account that repair work will be much cheaper than brake drums replacement. The serviceman removes the top layer by the lathe thus restoring initial condition of the part.

Brake drum replacement

If you found brake drum failures that you cannot eliminate, replace the component. It will be reasonable to replace the part at service station where high-precision calibration of the braking system can also be performed.
