I had the brake pads and rotors changed on the rear with OEM parts, and it doesn't look like the pads are being fully utilized, like the rear rotors have more rusty unused area than the fronts. Can't think of anything that went wrong because it is a pretty straight forward install...

Any ideas? searched for an hour and couldnt find ****.

 

This is the same for every car ever made. The front wheels see more braking stress because the weight of the car shifts forward when braking. (That's why front brakes are always larger and more powerful than the rears.)

 

I thiught about ghat, but the rotors I took off were being fully used. With no indications of not all the rotor not making full contact with the pad

 

This will probably change as you use the new rotors a bit more, as they begin to wear they should make full contact (whatever is hitting the rotor now will begin to wear down so that the whole surface is uniform).

 

Pics may help.

 

Are the rear pads supposed to be smaller than the fronts? It stops really well, it just looks like ****.

 

Ohhh. That's bad.

Are both sides the same? What kind of modifications have been made to the rear end? Was anything changed when you went to the corvette wheels?

 

Both are the exact same. No rear end mods... A few f body guys in town said that's just how it is...

Why is it doing this? There's only one pad that will fit the caliper, correct? Rotors too big?

 

Yeah that doesn't look right. It looks like the inside of the pad is no touching. Did you have the rotors turned?

 

New rotors

 

There's a slight vibration when I brake.

Do I need to bleed them?

 

Those pads don't look like the correct ones. Yes, they fit in the calipers, but the friction area is too small.

 

Yeah, sorry, I figured you just put them on ad they needed to be driven a bit, but yeah....that almost looks like the wrong sized pads like leadfoot4 said.

 

Are the calipers on the right way? Should only be one way for them to be on right? I saw a picture in a boom and the caliper looked slanted an mine are straight

 

they look like mine.

 

Just checked mine. The pads are correct and only a very small area of the rotor wears on the back. The only thing that looks odd is the feathering at the inside edge.

How many miles are on these pads at this point? Did you check the slider pins to make sure they were moving well.

... And before I forget - did you adjust your parking brake to those shiny new rotors while you had your calipers off? A lot of people miss the adjustment inside the rotor hats.

 

Not even 3k miles yet. What are the slider pins?

My ebrake engages at a good position in the cabin, I didnt need to adjust it.

I looked at an install manual and it showed the brake asembly on a 98 TA, the caliper was slanted a tad...mine are straight on like the picture looks, not slanted.

Is there only one way for the caliper to go back on?

 

Looks like a slide pin or hardware issue unless they are the wrong pads.check and see if the slide pins move in and out easily. If they are rough or siezed it will do this cause the caliper gets cocked crooked. Use silicone lube to lubricate them

 

Whoops should have read every thing the slide pins are where the caliper bolts too. You will see a rubber grommet on each one. where the bolts thread into is the slide pin. It goes in approximately 2" to the mounting bracket. And they need to move freely for the caliper to move properly

 

I had a couple of minutes of spare time, so I just took a walk out to my unheated, 22 degree garage, and looked at my rear rotors. They have a "swipe pattern" all the way to the inside of the hat, so my pads are indeed contacting ALL of the rotor, not just that small, outside band.

FWIW, my car is a '96, however...
