Drum brakes are a fairly well-known and old design. However, many automakers still use them on their vehicles, from budget sedans to crossovers. It is clear that the “drums” need maintenance. If this is not done, faulty mechanisms will lead to an accident. Let’s not forget about the nuances of operation. About this – in the material of the portal “AvtoVzglyad”.
Let’s start with the fact that the “drum” is a closed type unit. That is, with increased load, and even in the heat, it overheats faster than the disk mechanism. This should be taken into account when driving actively or while attacking mountain twisties. The brake pads, being “welded”, will no longer be able to provide the required deceleration efficiency, causing an accident, as the braking distance becomes longer.
A serious accident is unlikely to happen, but a minor accident can. Which is still unpleasant, since modern cars have very thin plastic bumpers. And the body part itself is expensive. In addition, there are quite a few delicate fasteners that also break on impact, making repairs more expensive.
The second drawback is that the “drums” work slower than drives and they have less stable properties. This is due to the non-permanent contact patch between the brake pad and the inner surface of the actual brake drum. They have less room for adjustment.
Let’s not forget the pads. Many owners of used budget cars save on consumables and buy something cheaper, since there are plenty of good ones on the market. However, few people know that no branded product can ignite when heated with an open flame.
As a result, the mechanisms will lead and you will have to change them, which will hurt the wallet of an already poor motorist. In addition, the brake lines can be damaged, which can lead to fuel leakage in the future. This is another possible solution.
Finally, these pads will simply crack from heating and loads. Large pieces will block the drum and thus the wheel. If this happens at high speed, loss of control and an accident are simply guaranteed.
