I forgot about this test. Great info. Especially on the temps.

Another great article about balance:

These guys are pretty open about their views on brakes, bbks, pads etc.

I might look into the Castrol LMA if I can find it local. Bert thanks for the info. That info reminded me of the LMA stuff.

 

valvoline synpower works great and can be found everywhere. Remember also that the higher the boiling points, the more often you will have to change the fluid, there is no perfect fluid with high BP's and long life

 

I agree.

The castrol LMA stands for Low Moisture Absorbtion. Probably best for my application, use and frequency of changes. Plus I think it still specs out decent

 

That link agrees with my point that brake pads are indeed a tradeoff. As for the the upsizing of the 05-06 rotors, realize also that while the rotor may be larger, it's not necessarily true that they upped the torque, as the caliper pistons may in fact be smaller (I don't know this for a fact, however), resulting in a smaller force being applied. My guess is they did this for better thermal handling rather than increased torque. Plus a bigger rotor looks better, of course.

 

I think we mostly agree. But IMHO, they upped the brake force via bigger rotors (to also increase the thermal capacity) and more piston area (my guess) in order to maintain the great 03-04 performance w/o having to use the agressive pads and eating up the rotors so much.

I'll guess I have some measuring to do when my 05 stuff gets here.

 

Could be. I'll be interested to hear the measurements...good luck with the project.

 

They arrived. Just no time to measure yet.

If someone has the piston size of the 03 front/rear brake piston, that would prevent me from having to measure later.

 

Okay. FINALLY made time to do the swap. Rear pads were just about toast so I decided to just get it over with

Some background information.
'03 and '04 Sedan, '04 and '05 Sedan X
Front: 11.7-inch X 0.9-inch power-assisted vented disc - 1 piston
Rear: 11.5-inch X 0.6-inch power-assisted vented disc - 1 piston

'05+ Sedan and Coupe, '06 Sedan X
Front: 12.6-inch X 1.1-inch power-assisted vented disc - 2 pistons
Rear: 12.1-inch X .63-inch power-assisted vented disc - 1 piston

Rotor weights/ dia and thickness
06+ NON BREMBO BRAKE SIZE INFO.

Fronts: Rotor 21.5 lbs 12.6" dia 28mm thick (used)

Caliper piston dia. 43mm od / 35mm id x 2 pistons (didn't know which one you need but I'm guessing it's the od). I also rounded up to the nearest mm it was close to 43 and 35 anyway


Rears: Rotor 13 lbs 12": dia. 16mm thick (used)

Caliper piston dia: 38mm od 29.25 mm id.

Onto the pics
Front done: Don't mind the paint, it wears off. lol I also put on the Technafit SS lines all around

bump for pics

 

subscribed. plan on doing this soon and will update afterwards....

 

Would all Z/G two-piston, non-brembo calipers work with the 04 Sedan?

 

What year Z/G? The set I got was from a 05 6MT coupe, and it's a direct swap on my 03.5 sedan, everything works.
