I've just purchased Wilwood Floor mounted pedals, the dual master cylinder brake pedal and the single Master cylinder pedal for the cluch..
I havent bought the master cylinders yet as im unsure what im supposed to get.

Wilwood make 3 models each with a different bore. The three size they have are:
3/4"
7/8"
1"

What is the difference between these 3 models, how would you make your desicion on what to get? Currently the car has its std brakes all around, only a 1pot system but im wanting to upgrade in the very near future, but im just trying to find a rear brake system that has a parking brake...
So yeah im just a tad confused on what bore Master Cylinder to use for the brakes

Your help will be greatly appreciated.

The larger the master cylinder size, the harder you will have to press the pedal to get the same amount of braking. Not like you'll have to stand on the pedal, just it will feel more solid. Unless you enjoy a very soft pedal and lots of travel, the largest master cylinder size is usually the best. I would not use one smaller for the brakes. For the clutch, the stock size is fine, as a larger one will increase pedal effort without much benefit.

I'd like more info on this. I hate Honda brakes and really want a better feel. Let me know what setup you are using, and how you will fit it. Thanks.

 

tnx Dr D,
I'll post pics and more details as soon as i find out the specs on my current brakes etc... Will like to here more views on this as well, i never thought brake systems could be so indepth, im learing everyday

 

to really figure out which ones ull need ull need the rotor size, # of pistons/caliper, size of pistons, etc... and then there is a formula to figure it out... i dont know what the forumla is though

 

Im gonna try and get all the info today, Will look out for that formula u mentioned.

Thanks!

 

i dont know if theyll figure it out for with other manufacturers stuff... but when u buy tilton mc's for pedals... they ask these questions and then figure out which ones u need

 

k the Front rotors are: 240mm while the rears are: 227mm
Im still trying to find out the size of the Piston, but its only 1 piston per caliper front and rear.
The thickness of the front rotors are around 20mm thick while the rear rotor thickness is about 10.5mm

okay found out the size of the pistons,

The fronts: 48.0mm / 1.89 inches
The Rears: 34.0mm / 1.34 inches
Im not sure if thats the correct way of converting it, used some web convertor..

So would anyone be able to tell me what size master cylinder i need to use for the front and rear from all the info i've given in this thread...

Thxs for the help so far
