When purchasing rotors choose the part store that gives you a choice of two different rotors (NAPA) purchase the rotors that are more expensive with a two year warranty on them ( always retain your receipts for warranty) then buy the ceramic metallic type brake pads they are more expensive but I have found that I get about 4 years service out of them. Always replace rotors when doing the brakes do not have them resurfaced, my experience after doing 40 to 50 brake jobs in recent years has been that the newer vehicles posses fairly thin rotors that after being resurfaced heat up an warp faster than a new set so I don't bother anymore with resurfacing especially when inspecting the rotor you see heat fracture cracks on the surfaces. Always clean off the protective coating provided on the rotors before installing with rubbing alcohol or acetone. When braking on hills apply brakes in spaced out intervals if possible to allow the vented discs to cool even for two to three second intervals this helps more than most are aware of.

Good Luck and be safe.

When I start slowing down the front tires start shaking after I apply the break. What is causing that ?


You have one or two warped front brake rotors.
Many things can cause warped rotors. Here are a few.
1) Braking quite a bit, causing the rotors to heat up, and then going through a mud puddle or water which will cause rapid cooling of the disc.
2) Rotors made in China, which sometimes will warp prematurely.
3) Rotors that have been "surfaced" (ground down) during a brake job beyond their recommended thickness.
4) Bad luck. ( re: Heaven knows)

3 Cures. (You ain't gonna believe this!)
a) Take the offending rotors off and hit them with a sledge hammer. This worked for me once. ( You frighten them to death.)
b) Take the car or rotors to a shop and see if they can "turn" them on a machine to true them up. This is the same machine that is used to "grind them down".
c) Replace them. I recommend no Chinese. (See above)

When applying brakes the steering wheel shakes.


If the steering wheel is shaking when you apply the brakes, this is usually caused by the front rotors being warped, you can either replace the rotors (replace front brake pads as well) or if they measure thick enough, they may be able to be machined to recover a smooth - non warped surface again. Your local Auto Zone, Advance Auto Parts, or any other parts place usually can machine the rotors for you at a resonable price, but sometimes it is better to just replace them.... the thinner the get machined the less heat they will disapate and could possibly warp again after a few thousand miles.

Hope this helps

When the speed over 50 miles, use of brake will make the car vibration.


Probably warped front brake rotors. This is common on all vehicles.

Car shakes when brakes are applied after being driven for about 30 minutes. Brake pads (front & rear) are fine and tires have about 10 miles.


rotors are probbably warp from heat or corroded heavely (check inner surface harder to see)
external surface is visible

2006 Kia LX Van has 60,000 miles front end shutters during braking. Bought and replaced pads with ceramic from napa.Did an alignment job and replaced tires all around with Toyo High Country. The rims are...


Yes I would say that the rotar is warped. I just had the same problem. Just barely touching the brake at hight speed and it felt like the car was going to jump over into oncoming traffic. I replaced both of the rotars and its like a new car. The abs light was on to. It was a blown fuse, I guess from where the antilock brake overloaded from trying to compensate for it?

Our 2007 AWD Edge has 25000 miles on it. We


Every 500 miles, no, if you meant 5000 then yes, but if the inside is extremely worn down that sounds more like an alignment issue. If it was just a rotation issue, then the front tires would most likely be the ones worn down the most, but they should still be evenly worn across the tread. Also, i wouldnt take it to the dealership unless you just want to spend more than you have to, ask around, find a reputable shop, anything but the dealerships.

Right rear pad and worse


The problem described here indicates that you may have the AWD (full time 4WD) drivetrain of the 2003 Element.

It is normal to have 1 side of the vehicle to have increased wear due to the transmission differential, that allows your vehicle's wheels to move at different speeds from the others (turning, inclines, etc.)

Your brake pads really need constant inspection and possible replacement (approx 5,000 miles) with everyday driving, and is really a consumable item like your fuel.

You will find that it is much cheaper to replace the brake pad/lining of your disc brakes than grinding down the supposedly shiny discs that slow down your vehicle.

RE: salt/snow, you can improve your discs' longevity by rinsing them out with warm water after being driven in extreme conditions.

Hope this helps.

Vibrating proplem


Your car has front disc brakes, the disc's are running out of true, as u apply the brake this causes the steering wheel to shake, the higher the speed the more u feel this, the solution is to have the front brake disc's machined true again on a brake lathe or if they are to thin replace them.

Driving with parking brake on


More likely than not you wore the parking brake pads down. The parking brake pads are seperate from the rear disc brakes. They are a drum style. The rear rotars are designed to work as both drum and disc.
I would say in 20 miles you did little no no damage to drivetrain.
Typically when you get a brake job they will adjust the parking brake shoes. It is extremly easy if you have already gone and removed the brake calipers. Essentially you pull off the rotor (you would need a tool for this called a puller. not expensive, maybe $10. Something somone doing your brakes would have. Once the rotars are off you just turn a star gear.
This might add $15-20 to a standard brake job. Maybe $50 if the shoes need to be replaced.
