What are the symptoms of a bad brake rotor?
Symptoms of a Bad or Failing Brake Rotor/Disc 1 Noisy Brakes. 2 Vibrations from the Brakes. 3 Grooves or Score Marks on the Rotor. 4 Increased Stopping Distances.
How are brake rotors attached to the wheel?
Brake rotors are bolted directly to the wheel hub, so they spin in direct relation to wheel speed. When the brake pedal is depressed, the calipers squeeze the brake pads against the spinning rotors to slow and stop the wheels and the vehicle.
When do brake rotors need to be replaced?
Since rotors work to slow the vehicle by using friction from direct contact with the brake pads, they do wear out over time and will eventually need to be replaced. When rotors have a problem, they usually produce any of the following 4 symptoms that alert the driver they require attention. 1. Noisy Brakes
Why do I have grooves in my brake rotor?
Over time, grooves or scoring marks can develop on the rotor from repeated contact with the brake pads. Scoring and grooves in a rotor can take away from its capacity to slow the vehicle, as well as cause vibration and pulsation that can be felt in the pedal.
What should I do about my Hyundai Elantra brake problems?

Why does my Hyundai Elantra not have a push pull gauge?
OWNERS SHOULD CHECK THEIR ON-LINE MANUAL FOR THE EXACT DETAILS. Why they do not have the tool, look at the ESSENTIAL SERVICE TOOL SURVEY FOR 2008 (on line) not a listing for a force push/pull gauge anywhere.
What causes a brake rotor to warp over time?
This heat can become too great for the original rotors, and cause the metal to warp over time. Once the rotor begins to warp, the warping process accelerates due to uneven heating of the brake rotor, and the issue will quickly turn from light pulsing of the pedal to full-vehicle vibration.
What kind of noise does a bad brake make?
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.

How to install a brake rotor on a Harley?
Bob shows how to remove the front tire and install a custom rotor. He removes the brake pads with the caliper still on the fork as not to damage the caliper. He carefully removes the caliper bolts, notes size and location and tells us to wrap the caliper so it does not ding the fender or caliper when we gently set it aside.
What are the problems with the Nissan NV?
Many Nissan NV drivers have met this problem and the metallic noises and impact noises from the engine also troubled and distracted their attention while driving. What’s more, engine performance reduced as hard starting or inability to start, loss of power while acceleration, and poor fuel economy.
Why are Nissan NV body parts pushed out front?
NV body parts are designed with the engine pushed out front like a pickup truck to create more room for the driver and passengers, as well as a higher rooftop for more cargo space.
What should be the distance between brake rotors?
Tip: While measuring, keep a distance of about 45’ apart and 10mm from the rotor edge as the actual brake pad doesn’t contact those edges. Also, for slotted rotors stay away from measuring the slots, as those will skew the results.
Do you have to resurface your brake rotors?
No. The rule here is resurface when necessary, don’t resurface when it isn’t necessary. If the rotors and drums are in relatively good condition (smooth and flat with no deep scoring, cracks, distortion or other damage), they do not have to be resurfaced.
What happens when a piston moves out of a brake rotor?
When a piston moves out, it twists the square cut seal slightly. This helps pull the piston back when the brakes are released to keep the pads from dragging against the rotors. But as a seal ages and loses elasticity, it doesn’t do as good a job of pulling back the piston.
What happens to the rubber seal on the brake rotors?
Rubber piston seals and dust boots harden and become brittle over time. One of the jobs the piston seals do besides keep the fluid where it belongs is to help retract the pistons when the brakes are released. When a piston moves out, it twists the square cut seal slightly.
