Braking force distribution

[damusto]

Hello I have question, what should be proper distribution of braking force between the front and rear axle in stock AE86 ?

[damusto]

Ok maybe I'll try to ask this question differently...

... is there any pressure reducer or regulator for the rear wheels, in stock AE86 braking system ?

There's a reducer for the back according to my inspection data sheet. I don't know the value though. Also two different BMC have been used on these cars despite the callipers being the same. I'm not 100% sure if they have different values or just the fitting has changed.

Thanks for reply, Mate.
Do U have brake torques on wheels in inspection data sheet ?

Unfortunately not. They are more concerned for equality than actual figures.

[damusto]

OK thanks anyway.

Does anyone know stock brake pads dimensions ?
I'd like to calculate their friction area

Great thanks a lot Oldeskewltoy, this will help.
I hope these drawings keep proportions.

You can't have different braking force with the same size MC piston.
The rear's pressure limiter does deliver reduced pressure before its valve finally closes.

The only devices that regulate stock brake pressures are abs and brake proportioning valves (attached to rear axle). I'm not sure if these cars are equiped with and such device. Other devices are custom made and are attached to the master cylinder, mostly on race cars.
