Shortly speaking

Problems after replacing brake discs and pads affect most cars. It takes time for new brake components to run in. Before this happens, there is noise and beating when braking, which is not a cause for concern. If, having driven several tens of kilometers, the problems do not disappear, they probably arose through an oversight of the mechanic.

The most common problems after replacing discs and pads

Replacing brake pads and discs is designed to improve the efficiency of the braking system. When we pick up a car from the workshop, we expect it to work like new. No wonder that Hearing crackling when braking, we begin to doubt if everything went as it should.

Noise after replacing a disc and pad is not always a cause for concern. During braking, the fluid pushes the piston downward, which brings both elements closer together. In direct contact, the friction pad rubs against the usable disc surface. Both components take time to arrive, which may require us to travel even several hundred kilometers.

Many drivers who have just replaced brake elements complain about the visible vehicle pulls to one side... Most often this is due to the careless installation of new elements. Inaccurate assembly can also cause beating of felt when pressing the brake.

What is the source of the problem?

Having just picked up the car, it will be difficult to prove exactly what might be wrong. First, it is worth looking at our possible errors and only after eliminating them, look for a malfunction in the actions of a specialist.

Problems arising from driver errors

When receiving a repaired vehicle from the garage, it is natural to want to test the functionality of the system being replaced. To check this, many drivers decide to continue. maximum vehicle acceleration and hard braking... This is a serious error that could damage the newly replaced components.

As we mentioned it takes time for new brake pads and discs to fit snugly together... This is a process that even requires several hundred kilometers of driving. Attempting hard braking results in overheating of the materials of both components, resulting in poor braking performance. Smelly brake pads after replacement this is the effect of such actions.

Problems after replacing discs and pads due to mechanic errors

Replacing brake discs and pads is a routine and relatively simple task that professionals face on a daily basis. Unfortunately, the rush and the desire to make an already uncomplicated job easier lead to omissions that exacerbate problems while driving.

Often, problems after replacing brake components are due to do not clean the hubs and terminals by a mechanic... Replacing the pads and disc with new ones will give little if the elements that come into contact with them are rusty and dirty. Even a small amount of foreign matter will cause uneven disc wear, which is easily recognized by its characteristic runout when braking.

Another problem, which, unfortunately, is also not uncommon, is that careless assembly of components... Many experts do not pay attention to the exact tightening of the screws that secure individual assemblies. It is especially important to properly tighten the screws that position the disc and secure the brake caliper rails. Looseness or excessive pressure will result. severe beating and pulling the car to the sidewhich can be very dangerous during heavy braking.

Observe the car and draw conclusions

Self-diagnosis is not always easy. To find out if the listed components of your car are working properly, observe it. Pay close attention to braking style and make corrections. If, after a long time after picking up your vehicle from the workshop, you still experience the problems described above, please report your concerns to the mechanic who handled your vehicle. Never ignore signs that seem disturbing to you. It's better to check something extra, but instead make sure that the car is working properly and that you are safe while driving.
