i have searched and havent found much about which rear OEM calipers and rotors I can use to upgrade my OEM 02 Accord ones? I already have ITR calipers and Si VTEC rotors up front and would like to compliment that with something a little better in the rear. I am replacing my rear brakes so i figured while i was there i would upgrade the calipers and bigger rotors if possible. I'm wondering if the 4G Prelude setup in the rear is larger then my Accord one. I know for a fact the 6G Accord V6 rotors and calipers in the rear are the same as the I4.

 

Grab some cross drilled/slotted rotors off of ebay if you care that much about appearances. Because the proportioning valve limits the amount of braking force applied to the rear of the car during braking, not too many people mess with the brakes back there because their miniscule duty in braking doesn't affect much anyway.

 

If you have a 4 lug rear, then the first step is to convert to 5 lug. Then a later Accord rotor from, say a 2010, is a 282mm is a possible choice. But you would have to determine if the rotor will fit the hub properly, and then if the caliper bracket will work.

 

Because there is no point. If anything a larger rear caliper or rotor will cause more rear bias which in turn will upset the balance of the brake system. Your car would take longer to slow down, or worse, than with the factory bits.

With harder/faster/frequent braking, upgrading the front allows one to have a larger mass in the rotor as a heat sink/swept area. This allows for harder braking while not diminishing performance from overheating the front pads/rotors/fluid. There is an advantage from torque with a larger rotor as well.

Increasing the rear rotor size does not gain much. At best the brakes look symetrical front to rear, but with more uneeded rear bias it is most likely that the rears will lock up. Not good. Preferably you never lock up the rear before the fronts. If this happens more than likely the car will spin. This does noting for slowing quickly, and is dangerous.

Usually only vehicles that have a larger rear cargo carrying capacity requirement, such as vans and trucks, will have larger rear rotors and/or rear caliper pistons.

'95 Accord coupe/sedans use 260mm/57mm and 260mm/34mm combination.
'95 Accord wagons use a 282mm/57mm and 260mm/38mm combination
'95 Odyssey van use a 282mm/57mm and 282mm/38mm combination
There is an increased front rotor diameter for the heavier wagon, and it is balanced back out in the rear with a larger caliper piston. Then there is the Odyssey which uses an even larger rear rotor due to its heavier rear and larger cargo capacity.

For stopping power you are better off finding pads that will allow for maximum deceleration for the conditions, and fine tune with an adjustable proportioning valve to find the limit.

Click on the 'centric whitepapers' link in my sig, also look up 'StopTech whitepapers' for more performance based tech.

 

I installed 300mm Acura RL rotors on the front with NSX calipers. This gave the front a little too much bias so I changed the rear calipers to the 38mm ones. So far it seem to have balanced out the system a little better. But I also run slightly larger tires on the rear so this may have an effect as well.

It seems that almost all Accords run very much the same brake bias. In 2008 the Accords went to a larger rear rotor, probably because the car got bigger.

 

I appreciate the information. thank you.
