GTO BRAKE SWAP!!!

:... well the install is done here are the results...

I upgraded from the single piston Omega Brakes to the dual piston Pontiac GTO brakes and so far I love them.

The brakes work awesome and they seem like they stop way better then the OEM ones so it was well worth the money (100$):



ok enough talk here are the pictures:

They will not fit unless you also change to the 05-06 hub and disc, if that can even be done. Of course now you'll have hubs/discs with a different lug bolt pattern from stock meaning you'll need different wheels fore and aft. Might be the reason far no one has tried it that I know of.

Is it possible to change the rear calipers on a 99 Cat to the dual pistons on the rear

The rear calipers on all Cateras are already twin opposed calipers. One inside, one outside.

FYI: There is a set of 2004 GTO front calipers, brackets, and hoses for sale on the LS1GTO forum.

For the fronts, do we need to change the front rotors as well?

Nope you can use the OEM rotors.... the calipers center over the rotor exactly, so you dont need to make any changes...

Also the 04 GTOs came with rotors that were same size as the Cateras.... in the 05-06 they moved to larger rotor, so they had to offset the caliper and push it back some to clear....

Okay and just to verify, the rotor size is 11.7in in diameter right? I wonder if any of those GTO guys have another set they are willing to part with...

Do you guys know what tools are required for the swap?

I think a 13mm, 15mm and 17mm wrenches... I think you may need 19 or 18mm wrench for the bracket mounting bolts.. .

The brake line is 10-11mm the bolts for the calipers are 13-15mm

Thats about it...

Pad install with pins, or clips?

Well neither I suppose...

The bracket is where both pads are installed inside a 1/2" channel and then the caliper simply slides over them. Then the caliper is bolted to the bracket so that neither can move...

It took some simple tools to install mine, and took maybe 2 hours tops to complete the swap.

I will be selling a set soon as well..

Well man, if you have no one else in mind let me know!

dumb question...how do you get the sensor off the pads? i see a pin but its so rusted i cant tell how to pop it out, if it even pops out???

Okay so I'm looking at picture #2. What are the bolts on the far left for? The ones with the holes in them.

my guess would be since there are only 2 and they have holes, possibly banjo bolts for the brake lines on either side??

I was thinking that, but when I look at the install, I don't see their use. Plus the lines are already attached, just a little confused.

Will these bolt on? The work on the 2004 GTO, why not the Catera?

Is this too much for SS brake lines? lol

As far as the brakes go, the OEM hoses are plenty fine for what you will be doing... I think the increase in brake caliper surface area etc... greatly benefits the braking of the vehicle thus the solid brake lines are not needed.

If you want to go solid, then you will need to go fr/rr because if you only do the fronts the rears will still flex and the pedal feel wont be any more different then it is now..

As far as the willwood brakes, if it says they will fit 04 then those will work but the question is do you have 18" wheels to use them with the brakes and are 2000$ brakeds worth anything on a 2-4K car...

Gotcha on the lines, the Wilwood post was supposed to be funny for that exact reason, other than the V8, maybe one or two others the $1800 Wilwoods would be a great mod. On mine it would be a joke! Though my sell value may go up! Been looking on upgrading to a set of 18s or 19s, gotta connect that might be able to get me a good deal on wheel and rubber. So I'm holding out from buying a set online. I can get a decent set for 400-500 online so who knows.

...exactly why i havent invested more than ive had to other than basic maintainence...plus with 123k on the clock i dont know how much longer she has, tho the engine and tranny still feels strong and smooth
