Need advice about results from brake service
Howdy all,
First a little history.At about 32,000 miles I noticed that the brakes (probably front) were beginning to make a metallic squeaking noise (possibly worn to the wear tab). At this point they were still stopping smoothly and well. I took the car to a local brake shop and had front pads replaced, front rotors turned, rear pads replaced, and rear rotors turned. After getting the car back I noticed a scrubbing sound as soon as the pads engaged the rotors and the stopping distances seemed to have increased and on some occasions it seemed to take an unusal amount of distance to stop while the brake pedal had a slight vibration and seemed to go to the floor more readily than before ( I am accustomed on older vechicles ) to reaching a point where heavy pressure from my foot completely locks the brakes and allows no more pedal travel. ) and reminded me of older vechicles with air in their brake lines limiting braking power and giving an odd feel to the pedal. I followed the brake shops advice and waited @ 2,000 miles for the pads and rotors to wear in and I admit that the noise has been reduced and the feel is a little better. The pedal still seems to travel to the floor with not enough resistance, it doesn't seem to stop as quickly as it did with the original pads, and their remains a subtle vibration that either wasn't their previous to the brake work or was not noticeable. I took the car in to the dealer after I rolled past a stop sign where I felt I had applied brakes early enough to stop in time but went about a cars length into the intersection. The dealer looked at all 4 wheels and lubed "the pins" but said that nothing else was found indicating a problem. Q 1. Is the vibration a normal thing with new pads and resurfaced rotors? 2.Should I expect a firmer brake pedal feel with a hard stop from the pressure of the pedal instead of using all of the travel from the pedal ? 3. Since this makes me nervous not having a satisfactoy answer/explanation/solution what should I do next ? Thanks, Stan |

Re: Need advice about results from brake service
1. Vibration is NOT normal. Period. The original servicing facility
should be able to correct this. It sounds like the rotors were not turned properly. 2. The pads put on your car by the service facility may be of a different composition than the ones originally on your car. This can cause a variety of changes, including required application pressure. Can you lock the wheels or cause the abs to engage if you try. If not, there is a problem. Since the dealer was able to find nothing wrong, I suspect that you may just need to press the pedal harder in order to stop the vehicle. 3. You should demand the vibration be corrected. You should also be able to stop the car. If a dealer who is independent from the repair facility deems your brakes are operating normally, then they probably are. While I can't speak for the dealer, I would presume they were convinced that they were able to stop the car properly. Regardless, if you can't stop the vehicle, you will need to take whatever action is necessary for you to be able to do so. This may require installation of Hyundai pads or other pads with a softer composition than that which is currently on the vehicle. |
Re: Need advice about results from brake service
I don't represent myself to be an authority so the following are
strictly my opinions BUT, 1. Vibration or pusling during stopping is supposed to be SOLVED by resurfacing rotors or drums, not CAUSED. 2. A spongy and.or low pedal is generally caused by either or both air in the brake lines or a defective master cyliner. In any event it is definitely not normal. 3. As to what you should do I would go back where I had the job done and complain until they fix it, even if additional parts might be needed. Meanwhile soothe your nerves with a little Diana Krall, Anthony Wilson and Jeff Hamilton! On Mon, 27 Dec 2004 17:52:36 -0500, jazzisjazz@mindspring.com wrote: >1.

Re: Need advice about results from brake service
Vibration is not normal after a brake job. either the rotors were not turned
correctly, or re-installed incorrectly. Using brake pads of different composition will give different stopping results. Yes, Air in the lines can cause variance in the pedal height and travel. Quite simply, If the previous brakes gave you a differnet "feel" there is something wrong with the new installation. Be it Parts or installation, it needs to be fixed. One other thing, a brake job doesn't take 2000 miles to break in. Maybe 50-100. If they sent you out for 2000 miles, I would find another shop. they expected in 2000 miles you would adjust to the brake deficiencies, not that the brakes would adjust to the car. good Luck! <jazzisjazz@mindspring.com> wrote in message news:o941t0t9mftus336ha4igtm54juhn83jlo@4ax.com... > Howdy all, > > First a little history.At about 32,000 miles I noticed that the brakes > (probably front) were beginning to make a metallic squeaking noise > (possibly worn to the wear tab).
