2008 chevrolet malibu brake problem

Most likely problem is brake rotors warped. If you replaced pads without machining rotors, or if rotors are getting worn and close to minimum thickness, warping is more likely. If you replace the rotors, replace the pads at the same time. The pads that are on the car now are wearing unevenly due to the warped rotors and can cause new problems for the new ones.

That's what I would imagine. It is usually the front rotors that warp due to the fact that they work a little harder than the rears. However, rear rotors can warp. If you feel the shake more in the body of the car, so in the seat and you feel like the whole car is moving and the steering wheel stays mostly calm then I would imagine the rear rotors are warped. However if the shaking is felt mostly in the brake pedal and the steering wheel shakes too then it is probably your front rotors. Shops can usually resurface rotors and it may be cheaper than buying new, so that could be an option for you.

i think you have overheated the pads so the brakes just seemed to fade with a hard brake pedal but no stopping power ,they might be ok with some use as this will clean up the burnt surface of the pads ,if the disks show no blue colour then your ok and maybe a different grade of brake pads will resolve this problem

Normally a "pulsing" brake pedal means that that you have a warped brake rotor or the brake caliper is lose. I would start by taking the front wheel off and inspecting the brake pads and the rotor. If the brake pads are worn down bad replace them. Pay special attention to the brake rotors also as if the are grooved very bad, they should also be replaced.

Usually it is a warped brake rotor. Take a look at the car's maintenance history (was anything done that might be related to this new issue). Are there more then one person using the car. (any lead-foots in the family?), how many miles are on the car (it may be due for its first brake job).

yes that is a very common feeling in warped rotors, if you feel the brake pedal the pulsing then you defintly have warped rotors, replace rotors and brake pads, never reuse pads when they have been in contact with a warped rotor, they will cause the new rotors to warp also

you need to replace the rotors.On new vehicles the manufacturer designed the rotors along with other parts to be replaced at certain mileage or ware.When they ground the rotors they became thinner.So now when the brakes warm up the rotors are easier to warp,which is the problem your having now.

resurfacing rotors is not very expensive should be $40 to $80 . I believe you have brake pulsation . if so your mechanic is right and rotors are the round disk that pads grab on.

Rotors are a part of the disc brake braking system, and they warp due to a number of things. And the amount they warp ranges from very little, to quite a bit, so much so that you can feel the warpage in the brake pedal when you stop.

They can cost from $20.00 to $150.00 per rotor, depending on the vehicle. They can be turned at the auto repair shop for about $10.00 per rotor. There is 1 rotor per wheel. Turning them gives you a new rotor for all intents and purposes, but once turned, depending on how much was turned off, they cannot be turned again. So a badly warped rotor might can be turned, or might be too warped to be turned. A slightly warped rotor might can be turned again.
