I noticed the other active brake thread so I thought Id ask about my braking system.

The brakes work OK, not great but OK. The car stops fine, but the brakes wont lock up (front or back).

The car is in my sig. My system consists of 10.75 front discs, 11 inch drums rear. No booster, manual. The calipers are from a 72 Challenger. The master is a MP unit from the late 90s. I do believe it is a 1.125 bore. Not 100 percent on the bore size, but I do know it was bigger of two sizes listed in the MP catalog in 1998ish. I do have a dial type prop valve in the rear brakes.

Ive had the car back together for about 5 years. I drive it on the street as well as track.

But, I feel they arent "right" as I cant make them lock up. The pedal feel is good, not overally stiff or soft.

I assume I need a smaller bore master. Something around a 7/8 inch unit?
