^^^ I'm not even sure why you would want too?
Hey Guys, I'm doing the R33 caliper on a G-Series diff, mainly so I can keep the internal drum hand brake..
I just ran into this thread and saw what you guys have done with the twin calipers to get a hydraulic handbrake out of one of them..
What I've been wondering is there potentially anything wrong with running two calipers like you guys, but for both as the foot pedal brake...?
So, it would be two R33 calipers, hooked up in series on the same brake line, per disc on each side?
All good? Legal? Other thoughts?
Thanks

Need bigger brakes on rear, need non-hydro handbrake, don't want drums.. not many choices, if twin R33's will run with no issues, I've got everything I wanted for a reasonable price.
putting 2 calipers will not make you stop any quicker.
only advantage would be decreased pad heat and wear.
Hmm, maybe I'm thinking about it the wrong way then...?
I figure, brake pad area of contact + force on discs = braking power? Slows rotation of rotor/hub/wheel??
So, double the surface area with equal pressure to the first again - it's like going from single pot with small brake pad to two pot caliper with larger pad?
Where am I going wrong with my thinking here man??
Cheers..
Just remember, your braking force is only going to be as powerful as the friction of the tires on the road.
Two callipers will double the applied force on the rotor, but realistically it will be no advantage in a light car that can only have so much grip to the road.
Oh ok, I see what you guys are saying.. Yeah, I understand that once the wheels lock (stock and big brakes kits alike) that deceleration will be the same, etc.
Anyways.. Do you guys see any major pitfalls in the idea, and it should be avoided??
I was worried that one caliper might fade quicker, or in different areas of the pad to the other one, things like that...?
Just don't want to find later that my rears are locking quicker than the fronts or something..
While I'm doing the disc brake swap and the diff isn't in the car, just trying to go the extra effort to eliminate any future issues..

The reason people go dual calipers is so it doesn't mess with the pedal feel when you use a hydro handbrake so they have one normal caliper hooked up to the brake pedal then another caliper with separate lines to a hydro handbrake.
That's what I think the reason is anyway?

Yeah, that's pretty much it i think, but drum shoes can wear out quicker too..
Well, that, or you do it to if you loose your factory hand-brake form going to discs/bigger calipers.
Think someone mentioned that hydraulic handbrakes are illegal for road use but..
Yeah you need a cable handbrake for road use, well legal road use chances are if you want a hydro there will be other illegal mods so probably won't make it any worse if you have one.
