I think maybe if I had higher performance fronts I might get a better balance gived the weight transfer dynamic you mentioned in the Cobras.
What do you reckon professor Mike?  |
So your rears are locking way before the fronts? What size are the rear rotors and calipers?
Slowy,
If your fronts are locking way before your rears you need to add more line pressure to the rear circuit or take it out of the front circuit. That means an increase in crack pressure (that's if the valve is in the rear circuit).
The problem with Tandem master cylinders that most regular cars run is they have the same piston bore for front and rear. This means the caliper piston sizes need to be dialed in to suit. Easy done if you are a big manufacturer as you can ring up PBR and give them the spec of what you want. When we are taking parts from these production cars and adapting them to ours we end up with missmatched systems. Proportioning valves are used as a band-aid fix when they should be a tuning aid.
