I'm having a problem finding some replacement front brake calipers. I'm trying not to get the stockers but instead was thinking about some 2-piston calipers. Has anyone out there upgraded their calipers and if so, where did you get them? As far as 2-piston calipers go, is there that big of a difference and is it worth the money? I'm planning on getting some Powerslot rotors and Hawk Pads also, just can't find the calipers that I want. Any help and or direction would be great....

no one has ever done a brake upgrade on a bonneville.

Not the calipers, anyway. The single piston caliper is plenty, all you need. Some have went with drilled and slotted rotors with ceramic pads to upgrade the stopping power.

May I ask why you are wanting dual piston calipers?

dont quote me on this.. but i know the bville and the grand pix brakes are sorta close.. and there are ppl taking camaro and vette calipers puting them on the grand prix.. so im sure with some modifications is could work...

but then agian you can make anything work just depends on how much time and money ya willing to spend.....

I seem to go through rotors real fast and was hoping for better stoping power. So, I was planning on upgrading to slotted rotors and some performance pads and figured that better calipers might make sense too. Plus I think I need new calipers anyways because my pads were wearing worse on one side. I could be wrong though.

The most That I have done was installed Baer Rotors, they are crossdrilled and slotted.
I also use KVR Carbon fibre pads. I have used Hawk pads before, and didnt notice any difference, but they were on stock rotors. I am actually looking at fabin' up brackets so that I can run a four piston. I just did a complete SSBC 4 piston conver'. on my 76 GMC. 13.5 rotors in the front 12 in the back.

Usually what causes the pads to wear worse on one side is because the other side of the caliper isn't backing off of the rotor.

What I would suggest is just moving to slotted and drilled rotors, with ceramic pads. With those pads, the wear is considerably less. One thing you can check on is the two slider rods that the free side of the caliper rides on. Make sure it'* not dry, or the rubber "boot" isn't cracked or broken, or even gone.

If they are, may need new regular calipers anyway.

Correct me if I'm wrong, but moving to dual calipers will require a revamp of you brake lines, and maybe even an upgraded MBC. You'll need a hose to each caliper, unless the caliper is designed for one line in, and splits from there.

try www.ssbrakes.com they have a kit

Seems they do... For a 2000 Bonneville, they are:

$1,040.00 for the two front wheels only, and the minimum wheel size is 18", meaning that they will not work with the stock 17" rims.

If you want rear, too, then it'* an additional $830.00, and will work with a minimum 17" wheel size.


Kind of spendy, if you ask me... :?

/\ can you explain what you mean here /\
