Complete brake job...again!, i need new brakes Options

[liquor]

Well the topic says it all. 2 1/2 years ago I changed all four discs (plain brembos) + pads and
the guy at the garage now tells me my pads are going away and that i should change the discs too
(some have been threaded). I havent done much mileage since 2 years - mostly city driving and I
usually drive smooth on the car.

Do you believe its normal wear? or maybe cheap parts or bad installation or the garage trying to rip me off?

Also, whats the best place to buy the brakes ? (I know nopionline.com sells the brembos cheap)

Thanks

Hello liquor,
In March'06 I brought my 94GT to the dealer. They said that my rotors were badly rusted. They told me that I had a stuck caliper on one wheel. I couldn't see this from the outside of the vehicle but on the inside the rear and one side in the front; pads were barely making contact. This was after 12 years of use and 119 thousand miles. I losened the rusted caliper, found aftermarket (non dealer) rotors and replaced them myself.

Unless you brake hard, have put on a lot of miles or have some damaged parts. I wouldn't replace the rotors without knowing why they are bad after only two years of use.(especially if this is the same shop that did the work last time.)

GET DETAILS.
The one reason rotors need to be replaced is if they are damaged: warped, chipped, badly rusted,worn etc. and cannot be used in the present condition with new pads.

The shop should tell you that the reason for the replacement: If they can't or won't give you specific details. I would not allow for them to just jump to rotor replacement. Ask what and why.

Is it warped disks? If this is true how much are they warped?
Are the disks are worn? If this is true how much are they worn?
If you have worn or damaged parts which are contributing to the rotor wear?

1.Occasionally owners choose to have rotors machined with a lathe to eliminate the problem and bring the rotor back within specifications. With the high cost of labor many owners choose to skip spending any time messing with an old rotor and simply buy new rotor knowing that replacing both will eliminate any uncertainly. Unfortunately some shops simply say you need rotors because they don't want the hassle of working with your used parts.

2.If you are going to have the rotors turned on a lathe the shop has to know the standard thickness and how much they plan to remove from the rotor when they resurface them.

3.If all you rotors are in need of replacement that seems unusual. I am making the assumption that the emergency brakes are not influencing the replacement.

4.I got my my parts locally at AUTOPART INTERNATIONAL. The calipers were factory Toyota remanufactured and the the rotors were perfect fit for my old rotors.

The factory brake specifications are listed below.
