Skyline R32 Pedalbox Master Cylinder

[Morten Kiil Finsaas]

Hi!

I have been searching the forum but I havent got any closer to the solution.

First of all, I am mounting a Pedalbox from Wilwood, so I need to choose from wilwood master cylinders.

Second, I am upgrading my brakes to D2 356, 8Pot front brakes and 330, 6Pot rear brakes.

The pedal assembly that I have is this one:

I have read that the origional bore on the master cylinder is 25.4mm = 1"

The cylinders that I can choose from are:

Part No.: 260-3372, Bore: 0.625in, Stroke: 1.300in, Volume: 6,54ml

Part No.: 260-3374, Bore: 0.750in, Stroke: 1.100in, Volume: 7,96ml

Part No.: 260-1304, Bore: 0.750in, Stroke: 1.400in, Volume: 10,14ml

Part No.: 260-6764, Bore: 0.750in, Stroke: 1.430in, Volume: 10,35ml

Part No.: 260-3376, Bore: 0.875in, Stroke: 1.200in, Volume: 11,82ml

Part No.: 260-3378, Bore: 1.000in, Stroke: 1.000in, Volume: 12,87ml

Part No.: 260-6765, Bore: 0.875in, Stroke: 1.430in, Volume: 14,09ml

Part No.: 260-7563, Bore: 1.000in, Stroke: 1.100in, Volume: 14,16ml

Part No.: 260-3380, Bore: 1.063in, Stroke: 1.000in, Volume: 14,54ml

Part No.: 260-6766, Bore: 1.000in, Stroke: 1.430in, Volume: 18,40ml

That do you recomend?

The pedal assembly has a brake bias control, with one cylinder for front and one for rear.

And I found this one:

witch ends up prety high on the volume list, and has one output for front left and front right.

I dont know what you think about this?

or just use a single output and a splitter on the brake line?

thanks for the help.

i brought one from compbrake in the UK with .62 fro front and .7 for the rear which is what they recommended to me. Yet to fit it so i cant offer any more info yet but i to run the same calipers as you do.

I would serously be speaking to a specialist motorsport place who engineer braking systems for race cars.
