Replacing pads on BMW cars

BMW brake pads are an integral part of the braking system and have a direct impact on the process. It is thanks to the possibility of interaction between brake pads and discs that the driver has the opportunity to use standard or emergency braking on BMW cars.

In terms of construction, this vehicle's brake pads are made of a special material that incorporates special alloy pads that are highly resistant to the frictional force resulting from the contact between the brake pads and brake discs.

The brake system used on cars of this brand is one of the most advanced in Europe, which is confirmed by a large number of tests, as well as feedback from car owners around the world.

But physical wear, coupled with friction forces, cannot spare even high-quality pads. Gradually, they wear out and cease to fulfill their duties, as a result of which the life and health of the driver and passengers, other road users are in danger. The only way out is to replace them.

BMW Brake Pad Replacement Period

It is strictly individual for each car. According to information received from the manufacturer, this procedure should be carried out every 40 thousand kilometers or depending on the degree of wear. The on-board computer will inform the driver about the need to perform this action.

In addition, he himself may feel changes during the use of the machine, such as increased consumption of brake fluid, poor braking performance, increased pedal travel, possible destruction of the brake pad.

Aggressive driving style, in which speed is gained in a short time, and also quickly decelerates, significantly accelerates the failure of the pads. Yes, and sudden changes in temperature, especially with high humidity, have a negative effect. During operation, the temperature of the pads rises and the ingress of moisture causes them to cool rapidly.

Step-by-step replacement of brake pads on a BMW car

On machines from a Bavarian manufacturer, this procedure is divided into replacing the front and rear pads, which is not much different.

Replacing the brake pads on the BMW E53

Replacing the brake pads on a BMW E53 car is as follows. The fact that the pads need to be replaced is indicated by the appearance of a message on the dashboard stating that the minimum thickness has been reached.

To remove the pads, follow these steps:

• Prepare accessories "34.1.050" and "34.1.080". It is necessary to tighten the parking brake and loosen the wheel bolts a little, depending on which wheels the pads are being changed on. It is also necessary to mark with paint or a marker the relative position of the wheels, hubs and disks;
• Using a syringe, pump out some brake fluid from the reservoir. Lift the necessary part of the machine, put it on supports and remove the wheels;
• If you need to continue using the pads, pay attention to their location relative to the calipers;
• Using a 7 head, unscrew the upper and lower caliper pins. Remove the caliper without disconnecting the brake hose;
• Move the piston as deep as possible into the cylinder;

Remove and replace pads, install in reverse order. Please note that the pads are tied to the direction of travel and install them exactly in the caliper. When replacing, the position of the retaining spring must also be taken into account.

Replacing pads on the BMW F10

If you try to change the pads on the BMW F10 yourself, you will have to work a little, as this car has an innovation that has completely changed the procedure for scheduled maintenance.

When performing this procedure, you will definitely need a scanner. If earlier it was possible to do without it, now the electric motor responsible for the parking brake is located in the rear caliper. After receiving the update, the EMF system has also changed.

First of all, it must be connected to the diagnostic connector. A special table will be displayed on the screen, where you need to select "Continue", after "Chassis" and EMF of the brake at idle. Number 4 will contain all diagnostic modes.

There will be quite a few registrations, but only one will be needed: the EMF workshop mode. After clicking on it, a list of service functions will be provided. In the list, you need to select the last line "Replacing the brake caliper or brake pads", which translates as "Replacing the caliper", and it should be selected.

After that, a key with this symbol is selected > Next, you need to go to screens 6 and 7, where it is easy to release the brake. The switch will display the "P" key; You will have to release the parking brake. Only then can new pads be installed. The ignition is turned off and the tablets are removed after going to screens 9 and 10.

After that, you need to remove the caliper and remove the pads, which is done quite simply. After completing this procedure, the scanner is no longer needed. To install new ones, you need to try to drown the piston into the caliper, to do this, remove the lock from the electric drive and turn the piston inside it. The pads are then loaded and you can snap the clip into place.

All actions with the correct caliper are performed in the same way. Now you need to assemble the pads together, everything is done automatically. To assemble the pads together, simply push the button up.

Finally, you need to return to the screen and select the CBS key, check the correct levels of the brake fluid, the condition of the engine oil.

The brake system of the car needs timely maintenance, as it ensures safety on the road. One of the procedures included in the standard type of service is the replacement of used brake pads and discs.

BMW vehicles have a special electronic system that warns the driver in advance of the need to replace the car. The average service life of brake pads in a car manufactured by a German company is 25 thousand kilometers, and sometimes more.

Brake discs are enough for two pad changes. With an aggressive driving style, the pads will fail after 10 thousand kilometers. Since most of the load is applied to the front wheels when braking, it is normal to quickly change the appropriate pads.

Its condition must be monitored, since a pad worn out to a layer of glue can lead to failure of the brake disc.

Brake pad replacement procedure

The whole process of replacing brake pads on a BMW can be divided into several stages:

•       Remove the wheels from the supports;
•       Removal of dirt and dust;
•       Removal of worn out brake pads and installation of new ones;
•       Installation of clips and fasteners;
•       Bleed the brake system;
•       Conducting a control test.

After completing all work, be sure to reset the service interval indicator.

The procedure for replacing brake pads on BMW cars is not particularly difficult, but has its own nuances for each model. They must be taken into account in order to facilitate the procedure and prevent the occurrence of malfunctions, so that all the necessary actions can be carried out independently.
