/\ can you explain what you mean here /\
I was just stating that ceramic pads will work fine with the stock calipers, and his wear will be considerably less.

I did go on to say that if the calipers are sticking, it does need to be addressed.

**EDIT** Changed my statement above to reflect what I meant.

I have stock rotors and ceramic pads and have plenty of stopping power.
The uneven wear could have been caused by not properly shiming the pads so they are even on the initial install. Or the spring clip could have came out of one end at some point?

$1k for upgraded brakes front only
I bought a disc brake conversion complete with tubular upper a-arms and new spindles for my 65 Acadian...$600

No warping on the rotor at all?

Cool! You may try that, then if the rotor warps under them, switch the rotors.

But, as mentioned, the sticking on the caliper does need to be addressed first and foremost.

Bout 15,000 miles so far, no warping and no brake dust
Just follow the companys break in procedure to 'season' the pads and rotors, thats the key

The GXP calipers (and rotors) should work great on your car. FYI, I'd advise doing both front AND rear to try and keep the balance.

this COULD also require a new proportioning valve as well.. however, i do not know if the GXP/SSEi/SEs all use the same or not

Yup I agree 100% on that, some research would have to be done...

From what I've read on the gp boards, they just swap over the calipers (and the pedal for them) with no nil effects. I don't think a new proportioning valve is needed.

I'm gonna see if I can hunt me down some GXP calipers and brackets myself. These brakes blow, the brake fade is the worst on any car i've EVER owned.

For the record, DRILLED rotors are a BAD idea on a street car. This is nothing but a cosmetic gimmick that will decrease your stopping power unless you increase the diameter of the rotor to make up for lost area.

In addition, most drilled rotors on the market will crack very early, and most brake shops won't turn them for that reason. Rotors that have the holes CAST into the blanks, not drilled, are a good option, but you still must increase your rotor diameter.

Drilled rotors have no purpose on a street car except for the excitement factor when one breaks on you.

Slotted is great. I prefer the Powerslot rotors with ceramic pads, but ultimately, it sounds like this car has a brake problem that needs to be resolved first. I would suspect sticking caliper bolts myself.

I wonder if GP GXP rotors would work with bigger wheels? They are cross drilled, and provide absolutely amazing stopping power.
