Default brakes

the front left brake seems to be grinding when making a hard stop,
also, when i'm driving they make a noise which im not too sure how to describe
they rub with each rotation of the wheel, im guessing its a warped rotor,
the dealer told me it was fine when i took it in but now im pretty sure they gave me a run around
to what extent are the brakes covered under warranty?
its an 02 elantra

if they make a grinding sound when coming to a stop and make an intermitent sound when driving, they are most likely warped.
the dealer should of checked each rotor to see if that is true, if they did and nothing came up then its probably not warped i guess.... BUT they should of atleast told you what it was and tried to fix ituzzled:

:cry:
Brakes that is my sore subject read my previous posts on my problems, and yes they are doing the exact same thing as yours. Besides the chattering when they get hot.

The dealers don't care.

I have been back 9 times.

They replaced Master Cylinder, Brake Booster. Still can't find it. I asked them to replace the car with only 2000 miles and give me another one. But they said no. So they fought me on a lemon law case which I am still fighting. Not only that It would of cost like nothing. Now the lawyers you pursue for everything, I just wanted my car fixed and taken care of.
I realized Hyundai doesn't care about me as a customer. I am going to start a web site maybe then Hyundai will listen..... :disappointed:

PS Now my car, has 12300 Miles, and the gas Guage doesn't read fill only 3/4, when the tank is really filled. They claim they may have to replace the fuel sensor. They have replaced soo much on this car. Seat Covers, transaxle seals, balance tires, align car, rattling back hatch, all MFG defects.


:shocked:

Forget about the dealers, think bigger. Call, email, fax, and write Hyundai USA. Tell them your situation, and make sure they know that you will make sure that all of your friends and family will not buy Hyundais in the future. They will listen then.

sorry a long long descrption , hope below message may help you...

Brake Noise:
Brake noise is far from subjective. Its usually an annoying high-pitched squeal. Hyundai brake systems
have been carefully designed to provide optimum braking under all driving conditions. One of the most
important components in the brake system is the brake pad material. The following factors have been taken
into consideration to select the best pad material:
E Technical and government regulations
E Stopping distance
E Vehicle control while braking
E Operating temperatures
E Brake pedal effort
E Brake pad and rotor wear
E Moisture resistance
E Friction coefficient stability
E Operating noise level
Brake noise levels may result in some instances even when optimum brake performance has been achieved.
Noises that are Normal:
Most brake noises are caused by a vibration of the pads and calipers as the pads grab the rotors when stopping
the vehicle. All vehicles will make brake noise under certain driving conditions. Brake noise such as
squealing, squeaking, grinding, scraping, growling,creeping, groaning, rumbling, etc., is sometimes normal
and sometimes not, but all can be annoying. The following noise should be considered normal:
1. Groaning noise at low mileage (0-300 miles)
a. Noise occurs with light to medium pedal force
b. Noise occurs during medium speed stops
(20-40 mph)
c. Noise usually doesnt occur on the first or second stop
d. Noise occurs with warm or hot brakes (not cold)
e. There may be a low frequency judder vibration
Hyundai applies protective coatings to the brake rotors and pads to reduce corrosion during shipping and
storage. These coatings may cause noise until they are worn off. Under normal driving conditions, this may
take about 300 miles. If this noise occurs during the first 300 miles, it is not necessary to make any repairs.
2. Groaning/Creeping noise (after 300 miles)
a. While the vehicle is barely moving, with light pedal force
b. More noticeable during warm, dry weather. This condition is most common on vehicles with
automatic transmissions, and is normal.
3. High-pitched squeaking/ scraping noise
a. Whenever brakes are applied. Usually heard from just one wheel.
Hyundai uses pad wear indicators to provide an
audible warning that the brake pads need replacement.
The pad wear indicator doesnt damage the rotor surface
if the pads are replaced in a reasonable time.
Check the rotor surface for damage, machine or
replace rotor if necessary and replace the brake pads.
4. Squeaking/Squealing noise
a. Noise occurs with light to medium pedal force
b. Noise occurs during low speed stops (5-20 mph)
c. More noticeable during warm, dry weather
This condition is common on higher-performance
vehicles that are designed to stop in short distances
from high speeds. If you are asked to correct this to satisfy
a customer, use the following procedure.
General Tips
The following may be helpful in resolving brake noise
conditions and improving customer satisfaction:
E Understand what the customer expects
E Never attempt to repair a brake-noise condition without verifying it first
E Remember that rear brake noise may sometimes be mistaken for front brake noise
E Verify the brake noise condition with the driver window both open and closed
E Check for the latest available information from Hyundai
If the noise persists, try the following:
E Replace the brake pads using the latest part number
E Chamfer the pads by about 2 mm before installing
E Apply an anti-squeal, high-viscosity, brake-disc
quieter on the pads
E Check the rotors for extreme wear and/or corrosion
Veither condition indicates that the rotors
should be replaced. If the rotors meet specifications,
clean them up on a lathe using a non-directional
swirl finish. An on-car-lathe is recommended
for machining rotors.
Perform the following bedding-in procedure to help reduce brake noise and make pads last longer:
1. From 30 to 40 mph, brake gently until the car almost stops. Re-accelerate to 30 to 40 mph and
stay there for 30 to 40 seconds while the brakes cool. Repeat this routine about five times.

2. Take the car up to 55 mph and brake gently down to 20 mph. Wait the same 30 to 40 seconds for the
brakes to cool, then repeat this four times.

This beds in the pads, helps reduce brake noise and keeps customers satisfied.

Hey schindler do you work for Hyundai?

Other vehicles I have owned do not do these, and also they should put this on the window sticker. It is just some brake noise is always normal, but the groning, etc.

My 97 expedition has never mad a noise...and that is my hard rider
