The braking system plays a very important role in safe driving. Faulty brakes often lead to emergency situations, and therefore it is necessary to carry out timely repair or replacement of the main parts of this system. This applies in particular to brake discs. It should be remembered that they only change in pairs. Otherwise, the car will brake unevenly, which can lead to unpleasant consequences.
Necessary
- - brake discs and pads;
- - standard set of tools;
- - jack;
- - spanners;
- - alcohol solvent;
- - rags.
Instructions
Step 1
Brake discs can fail due to malfunctions or normal wear and tear. In the first case, it is necessary to repair the brake system completely, and in the second, only to replace the brake discs. Moreover, for this it is necessary to know the dimensions of the latter. Each manufacturer places this data on the disk in the form of two numbers, which mean the minimum allowable value, as well as the nominal thickness.
Step 2
For example, if the runout of the brake disc is more than 0.1 mm, it must be changed, otherwise it can lead to vibration. In the event of a malfunction of the disks, when mechanical damage occurs, a groove can also be made, but only if their thickness allows this. The most common cause of damage is dirt, corrosion and other damage between the hub and the brake disc seating surface.
Step 3
Each car has its own design, and therefore, when replacing, you need to be guided by the repair instructions specifically for your car. Make sure the brake discs are clean before starting work. Also, remember to remove any dirt from the hub, otherwise the installation may cause various difficulties.
Step 4
So, remove the anti-corrosion protection with an alcohol solvent, and also check the runout of the disc, which must be examined both before installation and after assembly. After making sure everything is in order, remove the wheel. You will see the brake disc and caliper. By unscrewing the bottom bolt at the latter, you can take it off and pull out the brake pads.
Step 5
To replace the brake discs, you will also need to unscrew the bolts holding the caliper bracket. This easy manipulation involves dismantling the caliper. You can now remove the brake disc. For such a procedure, there are several holes in it, from which you need to unscrew the bolts. After you replace the old brake discs with new ones, install the caliper and fix it with brackets. Then install the brake pads and screw on the caliper.
Step 6
And finally, a few more tips. You need to buy brake discs in a specialized store. In this case, a certificate should be required, as well as a translation of the instructions, in which you can familiarize yourself with the recommendations for their replacement. Before installing, the seat must be cleaned of dirt and rust. When disassembling the brake system, remember to secure the caliper, as well as squeeze the piston of the brake slave cylinder. It must be squeezed out until the brake fluid begins to flow into the reservoir intended for it.
