Can you change brake discs yourself?

Can you change brake discs without changing pads?
We are often asked why brake discs cannot be replaced without replacing the pads at the same time. The main reason is that if you don’t replace brake discs and pads together, your brand new discs will wear unevenly and can get damaged.
How do you know when brake discs need replacing?
A grinding sound: If you hear a grinding noise when you brake, it could mean your brake pads or discs need replacing. Brake pads include a metal wear indicator that make a noise when it contacts the brake disc. When your pads are worn to this extent, it is likely you will need to replace the discs too.

Do you need to replace both brake discs?
The answer is YES. For example, the brake discs do not need to be changed if the car is relatively new and there is still a lot of disc life left. They absolutely need to be changed if the discs are unevenly worn or badly scored. Braking force is created by the brake pad and brake disc.
How much does it cost to replace brake pads and discs?

What happens if you don’t change your brake discs?
If you let your brakes go and never tend to them, the pads and rotors could wear out and go bad, and a number of other things can break down. These things operate together as a team in order to slow your vehicle. When one or more item is no longer working, your disc brakes can fail.
Is it better to change the brake pads and brake discs at the same time?
It is important to note, if the discs are unevenly worn or badly scored, that it is recommended to replace your brake pads and brake discs at the same time.
Are brake discs easy to replace?
Brake discs tend to last a lot longer than brake pads so most car manufacturers have taken to using them on the front wheels to prevent drivers from having to change them quite as often. The process of fitting new brake discs is not that difficult and doesn’t require any specialist equipment.
What happens if brake discs wear out?
When you drive with worn out brake pads, rotors, or calipers, you may find yourself slamming on the brake pedal more often to slow or stop the car. All this hard braking can wear your tires down quicker or cause them to become unbalanced, leading to uneven tire wear.
What is the wear limit on brake discs?
It is generally acceptable for two to three millimetres of wear. It’s easy to detect natural brake disc wear. A burr can be felt at the rim when a disc is worn, as the disc only becomes worn where the brake pad is applied.
What causes scoring on brake discs?
Scored brake discs This noise is caused by two metal pieces grinding together when braking. If your brakes have got to this stage you may also have felt some vibration through the steering wheel or brake pedal. Unsurprisingly metal on metal doesn’t stop you very well when compared to metal and rubber.
