Can You Replace Brake Pads And Not Rotors?

Do-it-yourself (DIY) automobile repairs are on the rise, contrary to expectations that fewer car owners would perform their maintenance because baby boomers are growing too old to work on their cars, and millennials are unwilling to do so. The replacement of brake pads is one of the most popular do-it-yourself repairs. Although it is a relatively simple task, specific concerns arise.

They are not rotors but brake pads. Is it possible to change them? Yes, it is possible to change the brake pads, but not the rotors. However, you will be required to replace the rotors at some point in the future. A standard piece of advice says you should change the rotors once every two times you return the pads. It is also possible to “turn” rotors to grind them down until they are smooth again.

Because brakes are the first line of defense against accidents, it is essential to perform routine maintenance on them and to keep an eye out for any symptoms of wear. Make sure you follow the correct techniques and utilize quality components if you decide to do any brake repairs.

The Operation of Disc Brakes

“disc brakes” and “rotor brakes” are synonymous with brakes. Strengthened steel is used to construct the disc, which rotates with the wheel assembly. When the brake pedal is depressed, pads that are formed of cast iron and equipped with a textured metallic covering exert pressure on the rotor. This causes the rotating disc to slow down until it stops completely.

To “squeeze” the rotor and bring it to a halt, two pads exert pressure on either side of the rotor. The pads are abrasive, which means that they cause wear on the rotor because they are textured with grit to provide grip strength. This indicates that it is time to either replace or resurface the rotors when the wear has defaced the disc’s surface so that the pads cannot make adequate contact with it.

It is possible to replace both the pads and the rotor, and the work associated with completing these jobs is designed to require just a minimal amount of disassembly and reassembly procedures.

The Ways to Recognize When It Is Time to Replace Your Brakes

Except for the most devoted gear nuts, only a tiny percentage of individuals try to visually examine their brakes regularly. Jacking up the vehicle, removing a tire (or two, if you have two distinct kinds of brakes), and drawing a brake system component is challenging.

A few things to keep an eye out for, pay attention to, or listen for are as follows:

  • Brake Light On
  • Noises From Brakes
  • Vibration or Shuddering When Braking
  • Leaking Brake Fluid
  • Soft Feel to Brake Pedal
  • “Hot” Smell
  • Pulling to One Side When Brakes Applied

Activation of the Brake Light

A brake warning light is shown on the dashboard of your vehicle unless you drive a 1957 Chevrolet that has been repaired. Depending on the technology available when your car is assembled, the brake warning light may either alert you that it is time to inspect the brakes or that sensors have identified a problem.

The brake light system of a vehicle manufactured within the last two to three years is most likely sensor-driven. When everything is in proper functioning condition, electronic brake pad wear sensors can glide on the end of a caliper, which is just a few millimeters away from the surface of the rotor.

On the other hand, the sensors will ultimately come into contact with the rotor when the brake caliper enters a groove formed by the brake pads’ wear and tear. This causes the system to illuminate the dashboard, indicating that the brake pads have reached the end of their useful life.

Generally speaking, the brake warning light will illuminate before you become aware of any other fault suggesting that the brakes are wearing out. Some automobile owners are indifferent about the warning light, thinking they have plenty of time for the repair. However, the longer you go without it, the quicker the brakes will wear out.

The sounds

In terms of sound and appearance, the noises from the brakes differ. The two significant sounds are as follows:

  • When the brake wear indicators come into contact with the rotor, a metallic squeal causes the vehicle to emit this sound. This is the warning light on the dashboard in the form of an auditory alert. It is possible to hear them while the vehicle is moving; oddly, they disappear when brakes are used.
  • The sound of grinding or scraping indicates a more significant issue. This suggests that the brake pads have reached the end of total wear and tear, and the holding plates of the pads are now making contact with the rotor. One must not, under any circumstances, disregard the distinctive sound of metal hitting metal. The rotors may sustain damage to the extent that they need to be replaced, even if the mileage may not necessarily require such a replacement.

The vibration

When you press the brakes, if you sense a shaking sensation in the steering wheel, this might be an indication that the brake pads are wearing out. You may not experience any vibration if your brake pads wear down evenly. However, if you wait long enough, the gouging of the metal rotor will eventually form a rough surface that “fights back” against the pressure the brake pads are applying.

Brake fluid that is leaking

There is a possibility that this is an instance of brake wear, but it is unlikely. There is a high probability that the master cylinder, brake lines, or fittings are the suspects in this situation.

Brake fluid rushes through the tube to the brake caliper when you use the brakes. This provides hydraulic pressure, which assists in pressing the brake pads down onto the rotor. It is possible that a seal is splitting or has become so worn that it cannot contain the fluid if it is leaking.

If it is necessary to bring the vehicle to a stop, a leak in the braking fluid might indicate that the additional pressure will enable the fluid to push open a seal momentarily. It is essential to consider the possibility that this is not the most probable option in this circumstance.

The brake Pedal Has a Spongy Feel to It.

If you are acquainted enough with the features of your vehicle, you should recognize when anything is acting unusually. If you feel that the travel of your brake pedal is more than it used to be, that you have to push harder to bring your vehicle to a stop, or that it is one way one day and another the next, then there is a problem with your brakes that necessitates a checkup.

This does not definitely indicate that your brake pads are worn, but it is one of the possibilities, and it is probably the most probable one. One possible explanation is that air or moisture is present in the master cylinder or the brake lines. Without a doubt, you should have this condition checked out as soon as possible.

Combustion of odor

If you come to a halt and instantly detect an unpleasant odor, the odor may be coming from your brakes after you have stopped. Your brakes may be overheating, or you may have been driving with your parking brake on. Both of these possibilities are possible.

Never go behind the wheel of a vehicle that is smoking, burning, or has overheated brakes. They may cause your brake fluid to boil and then release it into the environment, resulting in you having no brakes.

As brakes wear down, they are more likely to overheat.

To the Side, Pulling to One

If your brakes wear unevenly, the braking capacity of each brake will also wear unevenly. This disparity in stopping force has the potential to “pull” the vehicle in the direction of the brake, which is the primary source of effort.

Making a Rotor Rotate

By having a rotor “turned,” it is often possible to extend its lifespan. It is necessary to machine the surface of a rotor till it is smooth once again before turning it. It is not a do-it-yourself project.

Whenever the scoring on a rotor is more than half a millimeter deep, the rotor must be replaced or machined to a flawlessly flat surface. It is possible to machine the rotor by a total of little more than two millimeters, and this may be accomplished via a single procedure or by numerous turnings (which is exceptional). It is necessary to replace the rotor after that.

Lengthen the Time That Your Brake Pads Will Last

Your driving style significantly influences the amount of wear and tear that your vehicle experiences, especially its brakes. As you progressively slow down, you will most likely be required to come to a complete stop at the next junction. It is not a good idea to approach the intersection at full speed only to find that you must apply a lot of pressure on the brake pedal because the light has gone red. On many occasions, over a short period, this might cause the brakes to overheat, which can be dangerous.

There is a clutch-free manual shift option available in many current automobiles. Downshifting to a stop provides a significant benefit over upshifting from a halt through all of the gears, which is more work than it is worth. When you are getting close to a stop sign or a red light, you should pull the gearbox out of automatic mode and manually bring it down one gear. Downshift once again when a moment has passed. This causes the vehicle to slow down without the driver ever having to touch the brake pedal.
