- Warped brake rotors. This is the number-one braking myth. Perhaps it has become so ubiquitous because, at first, it appears to make sense. If you feel steering wheel vibrations or pedal pulsations when braking, then the disc’s surface must be uneven because it is “warped” from excessive temperatures, right?
- Bigger brakes will help you stop quicker. Brake rotors with a larger radius will increase the lever arm of the braking force over the center of the hub and, therefore, the braking torque applied to the wheel.
- Drilled or slotted brake rotors are better. We’ve already seen that fitting bigger rotors does not necessarily make sense for a normal street-driven vehicle.
- Disc brakes stop faster than drum brakes. Fewer and fewer cars nowadays use drum brakes and those that do only use them on the rear wheels, where the braking forces are lower.
- Your Brake Pedal Feels Soft or Weak. Your brake pedal should have a firm feel when you press on it. It should move freely as you move it from its resting position, and as the brakes are applied the pedal should become firmer with more pedal use.
- Your Brake Pedal Feels Solid as a Rock. As frustrating as a soft pedal is, a hard pedal can be equally appalling as you try to stop your car with no luck.
- Your Brakes Fail to Disengage. With a hard and soft pedal feel, your brakes still disengage after you apply the brakes. What happens if the brakes won’t let go?
- Your Brakes Squeal or Howl When You Step on The Pedal. Your brakes shouldn’t make any significant noise when applied, but when they start talking you need to listen.

When you press on the brake pedal and feel vibrations from the brake pedal this likely means that your brake rotors are warped and need to be replaced. Brake rotors can become warped when they are subjected to high levels of heat which can cause the metal brake rotor to bend and warp. The vibration that you are feeling is because the brake rotor su...
One way to tell that your brake rotors need to be replaced is by visually inspecting them to determine if there is a lip around the edge of the brake rotor. Over time a lip will form on the edge of the brake rotor as the brake pads start to wear into the brake rotor. While a large groove or lip at the outer most edge of the brake rotor is a sign th...
Brake rotors should be smooth and not have many surface imperfections. If you notice that your brake rotors have scored or have grooves etched into them this can be a sign that your brake rotors need to be replaced. When replacing your brake rotors it’s always best to replace your brake pads at the same time. Otherwise, you risk causing the same so...
Hearing grinding noises when you are braking is definitely a bad sign and is when you need to inspect your brakes for issues. A grinding noise when braking can indicate that your brake pads have worn down to the metal backing plate. When this happens the metal backing plate will grind into the surface of the brake rotor which it’s not designed to d...
But if you inspect your brake rotors and you notice that rust has started to form around the outer edge, this is usually a sign that your brake rotors will need to be replaced soon. Another reason why you may hear a grinding noise while braking is that your brake rotors are worn and falling apart. Brake rotors are designed to have a smooth surface ...
Let’s say you go to stop your car but notice that your brakes no longer stop your car the way they used to. This can be a symptom that there is something wrong with your brake rotors. If your brake pads and brake rotors become glazed over this can cause your brakes to not work as effectively as they used to. Another reason why your braking power ma...
Another symptom that your brake rotors are bad is cracks on the brake rotor surface. Cracks can develop in brake rotors after they have been heated up to extreme temperatures causing the steel brake rotor to form cracks on the surface of the brake rotor. These cracks are fine as long as they are on the surface level, if you notice that a piece of b...
Now that you have seen what brake rotors look like when they need to be replaced you should know what new brake rotors look like so that you can compare yours to new ones that way it gives you an idea as to how worn your brake rotors are. New brake rotors should look like the brake rotors in the below picture. If your brake rotors look more worn do...
Deciding to not ever replace your brake rotors can have dire consequences that can potentially leave you stranded on the side of the road. Let’s say that your brake rotors are worn now, you have 100,000 miles on your car and the brake rotors have still never been replaced. Over time your brake pads would wear into the surface of the brake rotor and...
Brake rotors by design will be flat and smooth. Usually, with warped brake rotors, you can’t tell with the naked eye that they are warped. The easiest way to tell if your brake pads are warped is to feel the brake pedal for vibrations or pulses when braking. Your brake pedal should feel smooth as you press on it and you should not feel any vibratio...
Mar 27, 2020 · A pulsation in the brake pedal. A grinding, screeching or growling noise when you brake. Of course, there are other problems in the braking system that can cause these problems. A brake caliper, which holds the brake pads and presses them against the rotor, can become sticky and wear out one brake pad, even causing damage to the rotor.
Air in brake fluid. Bad master cylinder. Bad caliper/wheel cylinder. Blown brake line. Bad residual valve. Fluid leak in system. Boiled brake fluid. Bad wheel bearing. The first thing to check with any brake issue is the fluid level and condition in the master cylinder reservoir.
Jul 26, 2021 · A. The only time you’ll need to replace your brake pads and rotors is when the pads are worn and your rotors are warped, though that doesn’t happen often. Rotors are engineered to last about ...

Jan 4, 2016 · 1. Noisy Brakes. One of the first symptoms commonly associated with bad brake rotors is noise. If the rotors are warped (meaning not perfectly flat) or severely worn, they may produce squealing or squeaking sounds. Usually, warped rotors will produce a squeak, while severely worn rotors will produce a scraping sound.
