I wanted to know if the front brakes pads and rear brake pads were interchangeable, because i am interested in buying EBC green stuff compound brake pads for the front, and wanted to know if I could just throw the front pads that I have on now (which are new) onto the back.

Nope... they're 2 different sizes... also it's pointless.

The usual time that the rear brakes actually do stoping is on light applications and parking brake. When you slam on the brakes, the front goes into work. You want to stop faster all around... Slots

edit:
Here I'll help you with a couple of other choices. I run Brembo slots all the way around, with normal pads, and they work great.

If you're looking for something more aggressive... BLEHMCO Our resident engineer and he has some Big brake kits.

Thanks a lot for the advice. Now i have to focus my money else where.

Note edit... I don't know if I got it soon enough.

I thought it was the other way around. Front brakes usually do the stopping, and rears come into play during hard braking only. I was just wondering since on my car, one side in the rear, the caliper is done for, and on the other side the pad is nearly finished, and my light braking seems fine.

It depends upon the system design. Usually the brakes are used in a X pattern. The F/L and R/R work off one branch, and F/R and R/L work off the other. The actual percentage for the brakes are around the following

Stop Front Rear

Light 40-50 60-50
Hard 60-70 40-30

That's why there's usually a nose dive on a hard brake. The valve keeps pressure on the rear to keep the front end from hitting the ground. But a majority of the braking comes from the front.

Hm, interesting. Thanks. So how about drums? Do drum brakes work the same way, or are they only applied during hard braking?

Brake type does not affect that configuration. If rear tires were to hit first & harder, on slippery conditions car would easily start spinning.

Theres also a load valve actuated by rear ground clearance: more rear load, more rear brakes.

Edit:
ActuAlly maxima has got Twin Load Sensing Valves... The load sensing valves should be periodically lubricated to function properly (use lithium grease or smtg)
They are to be adjusted with added rear axle load to 1323lb, rear & front bleeder valves open and twin press gauge attached...

Setting/adjusted pressure is 1. low pedal press, 2. high pedal press.
1. front: 711psi - rear 555-697psi
2. front: 1422psi - rear 739-939psi
