Brake master cylinder brace, and servo / booster removal
#21

I had already put on the 1.8 brakes all around, and was unhappy with front lockup all the time. My approach was to up the rears a little, with the larger sport caliper.
This was the fix for me, as now instead of the prop valve screwed to all the way more rear, to about 3 turns from the end, and now I can adjust for track conditions. No more flat spotted fronts, much less front pad wear, and now that the rears are actually biting the rotor, the noise is all but gone.
I cannot imagine a front only upgrade being manageable, and I now have another set of sport calipers to put on my street car!

My car now has 11.75" front rotors with 1.38" X4 pistons. and 11.44" rear rotors with 1.375" Sport caliper pistons but it still has a booster although it has a 1" Master cylinder.
The bias is great and tunable with this setup via the wilwood adjuster. But sometimes Heal toe and left foot braking the booster really jacks with brake feel and consistancy.
So in getting rid of the booster. it seems I would want to up the mechanical leverage ratio a bit to make up for the lack of boost? There are some options.
1) Go back to a 7/8" master cylinder.
2) Maybe use calipers with 1.5" pistons front and rear. Or maby 1.5" in the front and 4 piston 1.375" in the rear.
Designing the braking system from scratch I do have some options. I might even go to a dual master setup.

Just my "opinion" but I would think the 1" would be an improvement to mine, less pedal movement. I do not have issue with pedal pressure, but dont think less distace would be an issue.
Willwood tripple master is in my future, with luck this winter. I have good brakes, but with losing the E-Brake, one leak could be serious! The tripple (dual with clutch) would be safer, and more adjustable. I'm also in for less clutch pedal distance.
Bigger rotors are out for me till I can afford to change to 8 larger wheels.

Since you are in the UK, check these guys out
https://www.compbrake.com/product/ma...ylinder-kit-b/
Looks like a proper bit of kit, including a bellcrank to get the pedal ratio right, balance bar, dual AP master cylinders etc.
