Despite modern technology and the introduction, in the braking system, disks, the drums are still used on most cars. Thus, the issue of dismantling did not exhaust itself completely, its relevance is at the proper level.

Rear drum brakes, building

To begin with, we will analyze the structure of the braking mechanism.

It consists of a fixed part represented as brake shoes and a part that rotates with the wheel while driving.

The drum is a rotating element.

The process of reducing the speed is carried out by interaction, i.e. the friction of the drum and the pads, until a complete stop.

The structure of the device, in general, is not complicated, besides the cost is acceptable. Drum-type brakes have mechanical self.

What it is?

This process is due to the special structure of the pads. Their lower parts are connected.

Thus, in the process of braking, the block that in front, interacting with the drum, generates an additional force.

This helps to use the rear pad, which increases the efficiency of the entire process.

Dismantling brake drum It is a common phenomenon in the world of motorists.

This is due to the conditions for its operation.

The condition of the roadway, humidity, driving style, accidents affect the reduction of functions.

As for the road, everything is more or less clear here.

But with humidity, the problems are more serious.

Without paying a proper influence of the system, the processes of formation of corrosion are possible, which leads to a decrease in braking quality.

The condition also affects the driving style.

Cars manufactured for the mass population and not adapted to aggressive control are quickly overheated, which leads to a decrease in functions.

One of the most serious reasons for reducing the efficiency of the brake system is a traffic accident.

Depending on its scale, relevant repairs are carried out. In some cases, a complete replacement of the system is required.

But mostly the considered factors work in aggregate.

As a result, ideal conditions are created for the occurrence of scratches, grooves and others. Defects.

Despite the experience of the car owner, the data of the "diseases" of the system is easily determined in visual inspection.

In parallel, the removal of the drum should be inspected by the pads, and in particular their brake surface, including special linings.

How to remove the brake drum

Having understood in the structure, it seems that the removal of the brake drum is not a particularly difficult matter.

But this is a delusion, with long-term operation of the car, brake drums sometimes, quite often, "burn", which very complicates their removal.

There are three basic methods.

To begin with, we will analyze the more rigid method.

The jack rises the side, from the wheel of which it is necessary to dismantle the brake cylinder. Other wheels are fixed. Then the studs are eliminated, the wheel is removed. The car is installed under the car bridge so that the position is stored unshakable.

After conducting preparatory activities, sit behind the steering wheel, turn the ignition key, set the third gear and we look at the tachometer.

When achieving 3 thousand revolutions, the brake pedal is clamped.

The breakdown of the drum is possible immediately, but if this did not happen, we try until you achieve due results.

The method has its own minuses, one of which is the risk of injury.

In this regard, it is not desirable to find unauthorized persons in the damage zone. But in this way it is not necessary to use, knowingly knowing that the drum in a faulty state.

The second method implies the presence of you already guessed the puller.

But here you will need a certain experience of using it.

Market conditions allow you to purchase it without any problems.

But possessing due knowledge, there is an opportunity for its independent manufacture.

It will be necessary to make components. The device is simple enough.

To assemble it, you need to use the services of metal processing masters.

The holder is manufactured, the basis of which is a prepared metallic cylinder.

Captures are mounted on the bolts to it.

To establish the desired sizes, you can use the information located in the World Wide Web (Internet).

There are all the sizes by which the details should be made.

The assembly does not represent special difficulties.

remove the brake drum, heating

The third method is used in the occurrence of corrosive processes, as a result of which the drum is not denied.

In this case, it is necessary to increase the temperature of the compound so that, accordingly, to carry out its gap.

It uses the properties of boiling water.

The connection is evenly poured with hot water.

Boiling water ensures the connection of the connection at all points.

You should take care of safety and put on protective gloves.

Having done the operation, the bolts are easily dismantled, and the braking cylinder is removed.
