you like the 93 cobra mc? mm advised me the 94-95 cobra mc
I did a ton of research into Ford MC sizing. I think the '93 cobra MC is ideal.
This is what I learned. Since I have basically 03-04 Mach 1 brakes, i discovered they use a 1 1/16" MC bore. In fact, all hydroboosted 99+ GT's Mach 1's and CObras use a 1 1/16" bore MC. It's equivalent to the 94-95 Gt/V6 MC.
However, i also noticed the hydroboost setups are about 1/16" larger than the vacuum boosted counterparts. The MC for 94-95 CObras is a 15/16" bore MC. However, the 96-98 cobras have the same 38mm piston calipers as the 94-95. They run hydroboost. What's the MC bore size on those cars? 1"...up 1/16 from the vacuum brakes.
Another check...99-04 GT's and V6's. The GT's have hydroboost and use a 1 1/16" MC as mentioned before. The V6's are vacuum boosted..what MC do they have? 1" again.
So going by the fact that Mach 1's have hydroboost and use a 1 1/16" MC, i figure a 1" MC would be ideal.
I also did out the math by measuring the area of the pistons. The 99+ brakes have 40mm pistons vs the 38mm pistons of the 94-98 cars.
SO....what it basically means is if you have 94-98 Cobra calipers, the 94-95 Cobra MC is what you want. If you use a 93 Cobra MC, your pedal will be slightly on the firm side of things. If you use the 99-04 Cobra calipers, you want the '93 cobra MC like i have.
My pedal feels awesome and the brakes are very responsive.
One day when i get bored, i want to put all my data into a spread sheet so guys mixing and matching brake setups can calculate their hydraulic ratio and determine what MC to use. It's really not that hard. Area of all the caliper pistons added up divided by the area of the MC piston bore gives you a specific ratio. Most of the OEM setups are in the 14:1 to 15:1 range.
With the 94-95 GT/V6 MC, my hydraulic ratio was 12.7:1...which is to the firmer end of things. The smaller the number, the firmer the pedal. With the 93 cobra MC, my ratio is now 14.4:1 which is in the range of most of the OEM setups.
Like i said before, one day when i get bored...i'll make a spreadsheet
