Foreword: The brake system plays an important role in driving safety. My car is a rear drum brake that has been changed from a rear disc brake, and the disc brake also needs to be maintained on time; It is worth noting that the brake discs are easy to rust. If it is slightly rusty, it doesn’t matter. If the rust is serious, obvious shaking of the brake pedal, steering wheel, etc. will be found during braking. This situation has to be handled by the repair shop. Because the rust is too stubborn, not only cannot it be polished, but it will also accelerate the wear of the brake pads. If the brake discs are scratched too deep, they must be polished. The consequence of polishing is that the brake discs become thinner. On rainy days, brake discs encounter alternating hot and cold, which may easily cause disc cracking, which will be troublesome. Therefore, based on the above considerations, I plan to replace the original rear brake to ensure driving safety.
1. Introduction to the owner
Aika ID: Meteor Shower_007
City: Dalian
Car series:2013 Xinrui
mileage traveled: 12w kilometers
Maintenance content: Replace the original rear brake disc
2. Replacement process
After making an appointment for maintenance, I drove my car to the store early the next day.
The handsome little brother is helping me register.
After driving to the workstation, he began to remove the tires.
This brake disc is not from the original factory. There is slight rust around the disc and it is covered with scratches. I need to replace it today.
Start removing the brake cylinder.
Let me show you the original parts I need to replace. This set is a Xindong 1.4T original rear brake disc, together with 4 screws and the handbrake cable clip.
To show the details, the original brake discs are very thick and feel very good.
This is the relevant accessory.
The old brake discs on the car have been removed. Looking at them, do they feel thin and scratched?
There is no harm without comparison. Compare the old and new brake discs.
The little brother in charge of maintenance pressed the new brake disc in three steps.
Then fix the brake cylinder and bracket.
Finally, install the tire and you are done. The effect is great after pressing it?
The total consumption was 939 yuan, including all accessories and working hours.
3. Summary
The replaced brake disc has a layer of galvanized coating, so the brake should not be too hard. It takes a period of time to get the brake to reach the best condition. The replaced brake disc gave me more confidence. In the past, when I brake urgently, I always felt soft and I felt like it would swing left and right. Now the brake feels that the proportion of the rear wheel brake is much better than before. The previous brake problems have been fundamentally solved, so it is worth the replacement this time.
