Harmful agents for car brakes

During the operation of a muddy vehicle, it is inevitable that dirt will get into the nooks and crannies of the brake system. If this situation continues for a long time, the brake system parts may rust. Causes the brake system to operate incorrectly and can lead to dangerous situations during traffic, especially on highways. In addition, for drum brakes on the rear wheel, there is a strange sound when pressing the brake or the brake is stuck. This means that the car’s brake equipment has been corroded or the lubricant has dried out.

Car brake maintenance process

Car brake maintenance can take place within a few hours. However, they ensure your safety every time you participate in traffic.

Step 1: Remove the screws behind the brake bracket

Use a specialized wrench to remove the screws behind the brake bracket. If the vehicle has a wear sensor system, unplug it. Then you lift the bracket off the brake disc and then proceed to remove the brake pads.

Step 2: Unscrew the sliding bobbin outside the brake disc

After disassembling all the sliding bobbin parts outside the brake disc. Keep them in a box or in a clean location.

Step 3: Use car brake cleaning solution

In this step, you use specialized brake cleaning solutions to clean the brake pad support shackles and brake brackets. Clean plastic and rubber parts gently. Clean all dirt and rust in the grooves and nooks and crannies of the rack set.

Step 4: Apply grease to car brakes

After the bobbin slides, apply grease to this part. Use specialized beef grease to protect brake pads, eliminate screeching noise, increase hardness, and prolong brake pad life. Insert the pin into the hole and check the slipperiness to see if it meets the requirements.

Step 5: Complete maintenance work

Proceed to assemble the parts into their original positions, namely the brake shackles, brake pads, brake brackets, tighten the screws and then plug in the sensor system line.

Step 6: Reinstall the wheel

Install the wheel, tighten it enough and tighten the previously removed screws. Lower the window so that the wheel touches the ground. Tighten the wheel screws again.

Experience in car brake maintenance

During use, the brake is the part that is under the most pressure, receiving impacts from many different factors. Therefore, brake maintenance is extremely necessary and is carried out regularly. According to experts, cars should have their brake systems periodically maintained every 50,000 – 100,000km depending on vehicle usage conditions.

Observe while driving

While traveling in a car, drivers should pay attention to see if the car’s brake system is working well or not, and this needs to form a habit because the car’s brakes are a very important part. , taking on the task of protecting the lives of you and your passengers, pay attention to these points:

+ If your foot pedal is not firm on the brake pedal, or the pedal almost touches the floor before “sticking to the brake”, this situation may be due to lack of brake fluid or an oil leak, so you need to check carefully.

+ If you step on the brake pedal and the car vibrates or the steering wheel vibrates, you should replace the brake disc because the old brake disc may be too worn out or need to be resurfaced.

+ When using the brakes, there is a squeaking sound due to metal friction, which means that your brake pads are worn out, can no longer be used, and must be replaced quickly.

Observe the engine compartment

+ Check the amount of monthly oil stored in the trunk to ensure safe operation. You should check brake fluid once a month

+ When the amount of oil is exhausted, more needs to be added. In particular, if you observe a frequent drop in oil, the system may have a leak in the system’s main pipeline.

+ Before adding oil to the box, you need to pay attention to clean the mouth of the oil bottle so that dirty substances do not get into the system. Besides, in order not to damage the paint on the car body, avoid letting brake fluid drip onto the side of the car, especially in painted areas.

+ You should regularly open the oil box lid to check whether it is new oil or old, expired oil. If you see the oil change to a dark color, you need to change the oil.

Check the brake oil pipe system under the vehicle

To check the brake line system effectively, you need to jack up the vehicle and pay attention to observe the soft oil lines and hard metal pipes to see if there are any leaks.

In addition to checking the metal pipes running along the length of the vehicle, you should also check the rubber pipes that transfer oil to the oil pigs located at the wheels. For soft pipes, if there is a rough phenomenon, it is a sign of a leak. Be careful not to let these pipes touch the operating and heating parts of the vehicle

Check by removing the wheel

If you have experience, you can remove the wheel to check if your car’s brakes are still secure or not? You can see if the car’s brakes are scratched or not, what level of wear the brake discs are at, and whether they need to be replaced or not.

Usually, scratched brakes are caused by sand, dirt or rocks stuck between the brake pads and brake discs, causing scratches. If you feel like the brake disc surface is too scratched. Then you should send it to the maintenance department to re-coat the brake disc surface or replace it if necessary.

For drum brakes (drum brakes), checking is relatively more difficult. Because it is necessary to remove the brake drum to be able to inspect the inside. Check to see if the brakes are deformed, if the oil pump is still usable and if the lubricant in the brake lining needs to be changed.

Bleed the air after replacing the brake system

After checking and replacing the brake system, blowing the air is something maintenance staff often do after replacing the internal parts of the car’s brake system. This is because when replaced, air will still be mixed inside. Causes vehicle brakes to operate ineffectively and does not ensure safety.

Smoothen the brake disc

With many environmental influences such as soil, rock, weather, etc., brake discs can become bent, warped, rough or inconsistent in thickness. Therefore, in these cases, the most effective solution is to smooth the brake disc.

Brake disc is reversed

The phenomenon of reversed brake discs and unconcentric hubs occurs frequently. When braking, the working environment of brake discs and brake pads is extremely harsh: the surface has many impurities, high temperatures and sudden changes, easily causing deformation and uneven wear.

Besides, the cause of the brake disc being reversed is that the surface of the brake disc mounted on the hub and hub does not have absolutely flat contact due to the disassembly process or local deformation.

When you see the brakes suddenly vibrate or the brakes shift to one side, it is a sign that the brake disc is reversed. When these phenomena occur, you should immediately take your vehicle to a workshop or maintenance center so that technicians can check and take measures to fix the problem of brake discs with many scratches and rough surfaces. rugged.
